- How we installed the High-Performance S&S Camshaft in our Interceptor 650.
We approached this install in a peculiar way, as we wanted to gather accurate Dyno information on the cam's effect alone. We'll follow up with a more instructional video where we remove the head (as recommended by S&S), but for now, here are some tips and insights from the TEC workshop.
Take a look at the cam on our website: www.tecbikeparts.com/product/...
Here is a link to the (unofficial) Service Manual: drive.google.com/file/d/1EPfo...
Thanks for watching,

The enfield is looking well smart mate,.....even better than the triumph!!!, sorry my own personal view.
Shame you didn't fire the old girl up, take care on the road, see you later .👍👏👏
Thanks for making the effort on the excellent videos! I appreciate the stepped performance Dyno testing! Looking forward to some porting and bore kit!
You guys are awesome, as always!
Been waiting forever for someone to install these. Lovely video.
Ps- please post more videos of y'all whacking through the gears with these beautiful pipes. The world needs to hear more of it.
Here you are.😂

to gain more knowledge of 650twin to improve more bhp torque of your twin 650 In bestest form in the world ...
Btw hello ! 😂
Guys, your videos are the best...so informative.
A nice informative video ,will wait till you have ported the head to see who it goes , down to earth and easy to follow , thank you .
Innovation in engineering great to watch top job from Belfast Northern Ireland it's brilliant to be able to see that you're doing what big companies should be doing,, enjoying the videos ☘️☘️☘️☘️
Really nice explanation ref pros and cons of fitting the cam, thx 👍
I was waiting to see one of them, ah, thanks mate.
I really want to see the 865 kit! Also, no matter what I do to the motor, I want to improve the brakes. My Auto Shop Teacher began the entire program by saying, If you can’t stop it, or you can’t steer it, don’t drive it! Everything I’ve ever driven, in my work as a mechanic, test driver for one shop, or on my own cars began by testing the brakes and steering before I went on to anything else.
Excellent video very informative thanks for taking the time to do 👍🏍️
The bike sure does look pretty!
Very interesting. Some may say if you want a faster bike but a Triumph etc but I like my Interceptor.
People used to say the same when I had a GSX1400 but I had TTS change the cams and I fitted a KN and Akropovic exhaust, it flew (136 at the rear wheel) and Below a ton it wasn’t far off a Hayabusa.
Ive had the S&S cam fitted along with the stinger 2into1. I already have the dna filter and booster plug on my gt650. Where to start.... well the bike still keeps its essence but is just a bit more manic! The power is more instant and builds quicker through the gears, you find yourself over the national limit with plenty of oomph left to go if the mood takes you. It will rev all the way into the red no problem but is just as happy chugging around if the mood takes you keeping that ability to have a chilled ride.Overall, with the mods now fitted I think its a noticeably better and more versatile bike than standard.....and that stinger exhaust note is bliss. Thanks Tec.
Good to hear your thoughts on it. Is the drop in torque at lower rpm very noticeable to you? And has it affected some of the daily practicalities like starting, idling, fuel economy that you've noticed? Cheers
@@MrJulianneave hi mate, I actually changed bikes just last week moving over to a Harley! I will say it was a difficult decision that I finally made due to long rides with friends becoming uncomfortable and in no way diminishes my appreciation of the GT650. Now to answer your question, the cam made no difference at all to the basic functions such as idling. The supposed drop in torque for outright hp wasn't really significant at all, in fact I'd say after a few hundred miles on the bike it actually felt more predictable with a better torque spread throughout the range with the added bonus of being able to get more of a shift on should you want to. If I had another enfield I wouldn't hesitate in doing exactly the same mods again. Hope that helps, anything else just ask.
Oh and fuel economy. Strangely I felt that the fuel economy was the same if not slightly better! I put it down to the fact that the bike was quicker through the gears therefore requiring less effort to achieve the same speed as before. Not a clue if that is a scientifically apt view but it's all I could come up with. Thanks again.
@@redstormcrow Really appreciate the response. I've never had much interest in Harleys myself but I think they'd definitely fit the bill if you wanted more comfort and more relaxed cruising at higher speeds - hope it's going well for you! I think if I was to get a new bike I'd maybe go for a 1200cc Triumph like the Thruxton R, but couldn't really justify the extra cost to myself and don't really need the extra performance.
Yeah it's funny that you get some people like TEC with the opinion that the s&s cam significantly changes the character of the bike from a more tractable machine to a high revving "more Japanese" feeling bike, whilst others like yourself say the drop in torque wasn't really that noticeable. I suppose it's partially individual opinion. I'd definitely be keen to get a bit more of a free revving feeling and continuation of the power at higher rpm, but wouldn't want to lose too much of the ability to do easy hill starts with a pillion, or recover by just opening the throttle if you find yourself coming out of a corner a year high, or being able to stay in high gear up a hill by just twisting your wrist a bit more.
I currently have DNA filter, free flowing mufflers and headers and a powertronic ecu so figured the cam might be the last modification I do before I decide I'm done with chasing performance. Did you have an ecu tuner on yours, and if so did you get a map made on a dyno after installing the cam?
I've got a feeling we're both in Australia - I was thinking about maybe getting the work done at revelry cycles in Sydney, who seem to be pretty committed to these bikes.
@@MrJulianneave no mate, I'm in UK. I love revelry cycles, great company. I never thought I wasca harley-davidson man until I ride one. The s&s cam does change the character in the fact that I can only describe as schizophrenic, its basically the same as before but if you want to ride harder and faster it will certainly change personality to oblige. I didn't do a remap, I was planning one with a power commander when I changed bike I felt the booster plug made a massive difference to the bike at low revs and improved the gear shift, I have no explanation but a smoother ride. Also, I think that after riding the bike for a few hour or so rides after the cam was installed the bike seemed to adapt to the cam as I'm sure I did too. Honestly, money well spent in my opinion and with revelry nearby I wouldn't hesitate in letting them fettle my bike. Cheers.
This videos are amazing!
I was waiting to hear it running
for that see end of this video th-cam.com/video/ED4sYnCcJXY/w-d-xo.html
Excellent content
love it . . . makes me want to get a RE
Yessss. I’ve been waiting for this.
Me too and the results are what I expected
Just want to say guys, I think I'll be starting to work towards my biking licence in Spring 2021 and I'm hoping to pick up an interceptor when I've passed all my tests. Your videos have not only helped cement my love of the interceptor, but I also feel much better informed about the modifications I would want to make and think I'd be comfortable making a lot of these changes myself! Though I might start with the Stinger exhaust, fuel booster & DNA filter / intakes before I go around messing with the camshaft haha. Thanks for all your informative content!
04:36 Right there. That's me. So, I'm going for the exhaust system change I gather...
Nice vid xden
Great been waiting for this. Someone has done the 865 kit but the overall horsepower is the same as you got. The torque on the other hand has gone upto about 72nm. Also how did u manage to get the 49hp on the stock headers ?
sir plz upload more videos been wating for this
another video tomorrow and will try to get a few a month out from now. Work load permitting !
@@georgemilburn6213 same work load here too ,give us a nice view of whats inside the engine & how u r upgrading it clearly well we all love it
I would love to know if the 2 into 1 produces more power than the 2 into 2 big bore front pipe kit.
Workshop manual link?? Couldn't see it in the description??
Are you thinking about doing the cam with yours?

@@TECBikeParts do you have a link for the himalayan manual?
Thanks for the vid , going to get one early next year , doing the exhaust air filter and power plug , but as for the cam and big bore kit , if you want more power buy a bigger bike , and as far as the looks , nice job looks great , really do like the look
Hi
To some point I agree, power gains must not effect the basic bike's soul too much and most importantly be affordable.
It is easy to get carried away and pour cash into a bike in the search for more power. But in the case of the RE 650 the bike has been well designed, then had power removed for marketing reasons. Why would your bike smash the land speed record for its class, then not shout it from the rooftops like Triumph did in the 60's with the Bonneville. We live in different times now.
Perfect something else i want in my life. Now trying to how to make some more money post C19
Nice video.
George has finally got a proper lathe.
A 3:1 Clarke horror will be for sale soon.
Followed by a proper mill...
Interesting how a big bore Enfield has the same bore & stroke as an 865 Triumph.
Side by side, imo, shows how much more attractive the Triumph motor is over the blob that is the Enfield.
Sorry, but the designers should have swapped the whole bottom end round to replicate the wonderful look of the Redditch twins.
I am attached to my Clarke horror ( Nu TOOL actually) Had it for 30 years and I still like it for very small simple things.
I don't do that much machining at home so that new lathe is a bit over the top. But handy for making one off parts.
My mate just along the road has a great machine shop I can use anytime. but always handy to have something at hand.
Is it best to add one performance mod at a time for the ECU to make the adjustments? Or is it OK to pile on air filter, exhaust, fuel plug at once?
Great work....did u do any modifications to the head for improved cam profile or keep them stock..
Another great video thanks....but stop the teasing with the stinger exhaust just let us get our hands on them. Thanks again for your video guides. 👍
On web shop from tomorrow
@@TECBikeParts I will be poised to buy the minute they go on plus a set of those S&S cams 👍
Hello please i ask for you sir am install cam shaft S&S and then how much tappet adjustment clearance valve intak and exhaust. thanks you sir
@TEC Bike parts Any horsepower or torque specs on S&S Big Bore and this Camshaft with proper air filter and exhaust (cumulative) ? ESTIMATES OK.
Request to clarify my below mentioned doubt regarding usage of valve spring spacers provided with the purchase of S&S performance camshaft.
When my mechanic opened the engine top cover I noticed the stock valve springs are already compressed enough & it is coiled up, now if we add the additional valve spring spacers doesn't it further compress the valve springs and increase the load on the rocker arm?? Is it necessary to use these valve spring spacers??
Did you ever clean the ports and re-dyno the bike? Are you under Covid lockdown still?
Cool video. What fuel injection mods did you guys put on or is this just the stock fuel mapping? S&S doesn't say anything about this and I am wondering if their kits have or require a re-mapping. Look forward to your next video.
Hi
S an& s are not helping at all with this. it is still on stock ECU and tune and running well as you can see.
S &S offer a powercommander in the USA ,but without any tune installed !
If you wanted one you will be probably be better off getting dynojet to install and map one for you. Or wait till somebody else does and dynojet will let you use the tune if you buy a power commander from them.
A little late to the show but here nonetheless. How does this camshaft alter fuel mileage? I don't have a RE yet but doing my homework now for a near future purchase of an Interceptor 650. Thanks!
Please show is the power figures and how does the bike run after the mod. Please.
I was a bit surprised to see the cam lobes for left and right cylinders have different timing and duration. I suppose this is helps exhaust tuning with the uneven firing intervals. The valve durations still look pretty mild for the S&S cam so the original RE cam must have been barely opening the valves!
The intake and exhaust timing is different of course. Different specs left cylinder/right cylinder? That doesn't make sense unless it is because of the 270-degree crank (as compared to a 360-degree) so; good question.
@@frederickwoods5943 Hi
This was quite common on cams used when flat track racing V twins and 270 degree parallel twin motors like XS650 conversions when racers converted them from a 180 to 270 for better traction out of corners. S & S showing the heritage !
Hi, great video, good work! witch stage is this cam? i search and found stage 1 and stage 2, thanks
How long does it take to fit. Second time around?
I believe the RE 650 designer was ex Triumph hence the similarities.
All of them are ex Triumph, that's why the built the RE R&D centre at Bruntingthorpe 13 miles from Triumphs world headquarters, and not in India !
@@georgemilburn6213 yea interceptor and continental gt is designed in UK ...
@@georgemilburn6213 not all of them are ex -triumph
@@georgemilburn6213 I am glad that it is staffed by top UK bike Bloks, In India the knowledge and know how is lacking.
@@georgemilburn6213 It was joint R&D effort!! Both the R&D center in India & UK played their part.
I've noticed a notch on the S&S cam on the area where the cam socket goes on to 🤔 what is this for exactly, to me almost looks like some special tool would be used here. I currently doing a cam change and high compression piston's upgrade not a 865 it will still a 650 .
But how much has the exhaust, intake, and cam affected your range?
What tires are those? In the USA, I'm having issues finding dual sport tires that will fit.
👍🏻
Would it not be better to fit a strong valve spring then if you go to oversize bore it will well sorted shims always seem to be a copermise?
The stiffer the springs the more power is needed to open them.
You are clearly a very savvy mechanic/engineer but I personally couldn't be bothered doing all that work I'd just buy a triumph fill it with petrol wash it and above all ride it😁
Need help!! I have installed the s&s cams following instructions that came with them. Upon installation and firing it up we find that the high lift of the cams are causing the valve to hit the pistons. I am trying to figure out why. Please let me know if I might have done something wrong?
Timing off a peg?
Don't know how this worked out for you, but did you add the supplied shims under the valve springs?
Do you have the dyno results of the S&S camshaft with stock exhaust?
Wish I knew all that stuff.
S&S makes it clear their pistons and big bore kits cams etc. are for racing applications only "FOR CLOSED COURSE COMPETITION USE ONLY. NOT INTENDED FOR STREET USE. LEGAL IN CALIFORNIA ONLY FOR RACING VEHICLES WHICH MAY NEVER BE USED, OR REGISTERED OR LICENSED FOR USE, UPON A HIGHWAY", so while they want to sell them, maybe they are reticent to promote them in the general market. You will get guys throwing in an 865 kit, not putting a stronger clutch in and burning up a clutch. I put a cam in a Street twin and it was really pretty easy. The cam install on the RE doesn't seem suitable for the average owner as replacing the shims seems beyond most guys capability., plus removing the head to port the exhaust. But just my thoughts. AS always you present great information about the nitty gritty of the technical aspects on installation.
I agree, personally I would just change to a 2-1 exhaust as the extra benefits of fitting a cam are really not worth the time and cost unless you want to go much further.
53bhp and 55 lb torque just fitting the exhaust gives you will be enough for most people without diving into the motor .
@@georgemilburn6213 im waiting on your exhaust as we speak been corresponding with Mathew. I'm going to do the exhaust intake, and a 14 tooth countershaft sprocket as where i live 6 gear us pretty useless. No big highways. I think it will be fine for me and the limits of the stock suspension and brakes.
sounds like you will have a wheelie machine , LOL
@@TECBikeParts LOL, That's what everyone on the forums said when I put a 44 tooth rear sprocket on my Street twin, but it just added a subtle amount of first gear and low end grunt. and shortened the gear ratios which I felt that bike needed. I'd rather put on a larger rear sprocket (up 3 teeth) but I have not been able to source one yet, hint hint. not sure what will happen dropping one tooth on the front, but easy to swap out, and a cheap experiment :)
Is the fuelling re mapped to produce the extra power? Thank you
@NorCal Rider Well, if you don't remap the fueling you won't get much out of a recam
😊
So, you can use this cam on any of the 650's?
What tyres are on it ? Still stock wheels ?
Where can I get that seat on your bike ?
I want to install this part in my interceptor, just want to understand if I would require any other upgrade to be done as well... upgrade like exhaust, filters ecu???
To get the best from the cam you need to change the exhaust, but no other mods to ECU needed
@@georgemilburn6213 hey thanks so much, exhaust is quite an issue in India....
I caught one comment. A free workshop manual. Where would I obtain this please. A friend has acquired the beautiful chrome tank model and I will prob7end up servicing.
see-www.royalenfieldlesite.fr/spip/IMG/pdf/service_manual_-_p_model.pdf?fbclid=IwAR1Ctsu3X-1_e9l2fkoDTM6-6CCaqx-ooLD45oi2ge212MkTw4SVJxUeE-w
This is horsepower at the wheel, right?
Cam for Meteor 350..? Would it even help ?
working on it !
What about how the cam sounds at idle?!? Is it lumpy now?
no noticeable difference to idle
Was the cam installed centered on the gear or was any advance/retard dialed in? I just ordered one for my bike. I’ll probably give it some advance.
@@CQBWarfighter Hi installed exactly on timing marks, as we wanted to see the results at recommended setting first
I seen ppl with high compression pistons , tuner , cam , full exhaust only geting 55hp
Instead of going 865 in the future any thought to just using the 650 high compression piston kit. To me keeping at 650 is more authentic to the RE and not trying to make it a poor mans Triumph
Yes we thought that too, but S&S is not selling them in Europe yet
Go half way with the "750 kit", it is 742cc and should make 52-55hp with only the TEC SS-304 silencers and standard cam. I am going this route with my 2020 650INT am have posted some of the process on FB already. The TEC silencers actually improved my fuel economy.
@@frederickwoods5943 it seems if your going to the trouble to remove the engine to install a big bore kit, you might as well drop in a cam.
that was vary cleaver putting 40psi in ro the cylender to close the valves.
4.03 Japan has left the chat...
Do a top speed run with all these mods
Now put a big bore kit and dyno it.
If you want to restore your lost torque - there's a magic torque multiplier called "gearing"! Add a tooth or two to the rear sprocket and the bike will pull as hard as before at lower revs and the new top end means you can carry the revs rather than run out of puff.
Adding teeth to the back you lose top end tho so fuck that
@@danielkerr4100 Not it the bike has more power up top - as it should with the new cam - it's a win/win.
How long will this take to install at a garage?
I think the guys who fitted mine at a main dealer took around 4 hours with testing. It is a one off job for most garages to be fair.
@@redstormcrow it did take around that long, with around 1.5hours dyno time
@@Agent01Orange it does take a little from the torque but gives it back in bhp, a fair trade considering the amount of torque available with the 2 into 1 fitted. It allows me to run with bigger engined bikes comfortably.
Do you have an updated timeline for release of you TEC factory style header pipes for the Continental GT 650? Someone in India posted a video last month with an S&S “full” exhaust system, but S&S sold the manufacture rights to Royal Enfield in 2019.They were either on an old prototype, or something R.E. Is about to release. “About” could mean never. I’d rather support you if you make them.
Hi
Are you thinking of a company called SS moto in India (rip off name) They have made a copy of our 2-1 with a bigger silencer, but are charging a lot more than us for it.
@@georgemilburn6213 No, the video claims its S&S Cycle in Wisconsin USA. The bike also has the S&S Race Only Silencers. You'll see the header pipe is smooth with no buldge from the cat. You Tube: THE RIDER'S VIEW-Custom Royal Enfield Interceptor 650
th-cam.com/video/dV4BRmIvYq8/w-d-xo.html
Let me know what you think.
@@brookcampbell2940 must be looking at something different, can you send me a link
@@georgemilburn6213 and that pipe (Indian SSmoto) is crap, even if you only look at it on video, I saw some dyno charts on it and they were pathetic.
I can tell you 100% that S&S Cycle in USA made a set of stainless steel catless header for the 650 twins. It was posted on their website in a PDF price list when I looked on 6-30-19. By the time I took my Continental GT 650 home on 7-2-19, the website was revised and the headers missing. I went round and round with S&S for a couple of months before they finally told me they sold the rights to the headers to R.E..The mystery continues! At some point R.E. may release these or not. This is a HUGE opportunity for someone to make a set of free flowing header pipes, without mid-stream Cat Converters, to mimic the factory routing allowing use of any number of silencers. The 2 into 1 looks great on some Interceptors, but the Continental GT. I have sever buyers remorse after buying the 650 GT and lack of support from R.E. I should have purchased that Thruxton R from Thailand. At least triumphand their partners support the bikes.
Mine revs like crap with the standard cam.
isn't that cam supposed to go with the pistons and big bore kit?....
It can be used on its own but as with fitting most cams with longer valve timing you lose power and torque at the bottom end of the range and gain at the top.
If you also fit the 865 kit you should gain all the way through the Rev range. Hopefully someone will post a video of a bike with both mods fitted.
A guy posted a video a few days ago of his Interceptor with the 865 kit and it was pulling wheelies.
@@nigeh5326
Do you have a link to the video?
Strideo1 sorry no just try a search for big bore kit interceptor
Maybe I'm alone in my thinking here, but I reckon it would be a right laugh to see you cursing and swearing, George. Especially with that accent.
Hi
link to service manual -www.royalenfieldlesite.fr/spip/IMG/pdf/service_manual_-_p_model.pdf?fbclid=IwAR1Ctsu3X-1_e9l2fkoDTM6-6CCaqx-ooLD45oi2ge212MkTw4SVJxUeE-w
Very informative and interesting BUT surely its missing the point of this bike. Early Japanese had higher performing engines in inferior chassis/running gear. I get improving the torque but turning the engine into a high rev sports type engine. Buy an old r6 and tune the ass out of it. As an experiment to see the highest performance you can achieve I suppose is of value.
Yes I total see your point and personally for my own use would just fit an exhaust system , as this enhances the essence of the bike . For me the cam is starting to affect the motors character too much and like I say now feels more like a Honda motor in it's power delivery . A lot of younger riders may feel at home with a rev hungry motor, but I like the mid range grunt a 2-1 exhaust and slightly milder cam gives you. I may make my own 'stump puller ' cam tuned particularly for torque, but this would probably not be for production. Best way for more torque is more cc's but cost to benefit on a £5500 bike has to be questioned. especially as I was more than happy with the 53bhp simply bolting on an exhaust and air filter gave ( also easily taken off again when selling a bike). I think that spec hits the bikes sweet spot !
@@georgemilburn6213 Well said sir👍
The link does not work😫
Hi
sorry it look's like youtube or google has removed or blocking it. Try searching via interceptors owners pages on facebook as they had a few links to it listed
Please don't get me wrong, each to there own, but I really do not understand why you would buy a bike like the RE 650 and them try to make it a fast bike? Why not just buy a fast bike to begin with? Your quality of work and knowledge is without question. However, your judgment to do all of this in the first place is a bit spotty, in my opinion. But, party on...
The stock RE 650 motor is lightly tuned/understressed, but does have plenty of potential. What is spotty about an engineer wanted to explore that?? Seems natural.
When these things first came out I got so much flack for suggesting that a 650 twin should be easily capable of producing 20% more power than the quoted and test figures.
It was if I was talking heresy, akin to suggesting fitting a turbo to the baby Jesus!
The biker world has apparently grown old and stupid. It’s as if the desire is for an antidote to the Blackbird/Hayabusa/Kawasaki thing race to the top end of the speed chart, by begging for a kiddies paddling pool - and water wings just in case the tiny Swedish Elf puppet gets upset because the plants get ‘too much’ carbon!!
In my humble opinion, these Triumph inspired, Anglo Indian re-imagined ‘Royal Enfield’ 650s are perfect for creating REAL cafe racers, as opposed to the passé racers with their vacant Bermuda Triangles behind the carbs, impractical, thin, cross-ribbed poser seats in brown leather - with integrated LEDs!!!
For an authentic modern cafe racer:
Alloy rims; alloy GP tank; alloy mudguards; the decent exhaust and cam fitted here; bigger valves; gas flowed head (including widened and polished exhaust ports); big bore kit if you like.
Plus, as well as getting rid of all the Eurotwattery sensors... CARBS! A pair of Amal Mk II Concentrics would be an historically appropriate choice. Maybe enough to achieve 60bhp?
How nice would that be?
Did I just describe a proper bike? You be the judge.
“It feels more Japanese” and “You lose a bit of torque at the low end”. Hmmm. Not for me, ta.
You could just fit the exhaust
@@stevemarshall5197 Amazing.
Yep🤔 to my mind the best bang for your buck is the DNA filter plus the stinger exhaust plus maybe a couple of iridium plugs 😊
I fitted the cam at stock timing, but we will experiment with dialling in some advance on the cam to get back some torque
@@stevemarshall5197 Yes that is the logical thing to do and far easier as well as the weight saving bonus
Just kick it up to 750cc and call it good.
I think the message here is don't buy cornflakes if you want Weet-Bix for breakfast. Nothing wrong with the work you are doing but why buy a cheap, lazy cruising bike and spend all the money you saved turning it into something it was never designed to be? Just buy one of the many sports bikes that will hose this any day of the week, even after all the mods.
