Interesting to see what a few modifications can do. Taking off the weight from the exhaust system must also make a difference to how the bike feels.
Any improvement in power is always welcomed,modern bikes are strangled.
I'm not convinced the 650 twins really need a bigger front sprocket. I live in rural Australia and I spend most of my time on my Interceptor at 90-110 kmh and I don't feel it's over revving. At 110kmh it's doing about 4500rpm which is 60% of the revs to the red line and the engine is really in a sweet spot at that point.
Nice sound..
Let's see what can be done with the engine...
Thanks
Hi ya. Any chance you could tell me if you are getting pops and bangs on the decel?
I have the big bore and filter but not the fuel x and don’t wanna loose the pops with the fuel x.
Thx
I would like to see a modern Enfield twin tested against a good T140 for performance and handling. The chap that sold me my Triumph also had an Interceptor - he thought the T140 was quicker...
With an extra 100cc of displacement the T140 had better be quicker. Now compare the T140 to a Royal Enfield Interceptor 865cc.
@@TheSkeptic-lz2cc Maybe, but the power of both is similar - I assume the T140 is lighter. 360 crank v 270. OHV v OHC, EFI v Carbs - I think it would be interesting.
@@gmhgb Ok, but at least unchoke the Interceptor's engine by removing the catalysts and giving it more fuel (Interceptors are now meeting Euro5 standards). And displacement matters a lot. Put the S&S 750cc pistons in the Interceptor.
Of course the T140 is faster. If it's running right, anyway. I doubt a stock 650 Interceptor would even outrun a stock 1972 Yamaha XS 650.
The T140 would probably be faster. The big question vill be for how long before it has shaked itself to bits.
I have the same setup, With ECU and AFR mods from Powertronics. Now, I am itching to install a high raise cams and bigger Valves. But the stock frame, brakes and shocks are just not aligned with the performance.
Was the camshaft upgraded?
With the YSS front fork kit, did you enlarge the holes on the damper rods?
I'm running Stratos headers, aew 201's with baffles, Stratos intake retainer and filter. PC5 set up on a roller. A smidge under 50bhp at the wheel. Really eager to run up the road now.
Just different dyno showing different numbers
@@morri03 Same Dyno used on the before and after. I'll dig it out when I get home and scan it. Great improvement over stock. Mpg has suffered slightly though.🤣🤣
@@peterwilson8797 what was the before number?
@@morri03 need to dig it out. A lot lower than advertised being at the wheel.
I would love to see you do an 865 kit with cams ,exhaust & tune.
But really though , wouldn’t an upgraded camshaft make a significant difference?
About 70hp in that case
You should be able to get decent hp from a 750 version if it breaths. I'd like to compare the 650 Enfield with a 650 BSA A65. But from building an 883cc A65 and a 734 A65 the 750 should make ample power. And the bigger motor is not particularly nicer nor worth the extra effort. I have only dynoed the 883 with a best of 85hp at the wheel, though it was lean enough to knock a few hp off. The 734 punches really hard. If it made the same hp to cc it would be 70.6hp and at the engine that would be around 80hp, but it feels much better than that.
when i had an interceptor i put hagon rear shocks loads better paul west yorkshire
I find the supposed benefits of very lean mixtures questionable, with the resulting hot exhaust temperatures and generally high engine temperatures (particularly in town), and it actually increases NOx - I'd consider maximising the life of the engine as more 'environmentally friendly'.
Big expensive, for minimum gains, 😮
Ignore the numbers, bike will run and feel much better
@@churchofbrap876 well a remap alone would of sorted the air/fuel mix. Everything else for a 2hp gain is pointless, especially in these bikes.
@@richardclark1448 some like the look and sound of the aftermarket exhaust
@@churchofbrap876 not knocking the look, but an awful investment for little gains.
@@richardclark1448 bike will run better, look better, sound better. You're too focused on numbers.
I wonder how much of this improvement is psychological because the rider knew that it had been tuned and the exhaust noise? Dont think that 2-3 extra bhp would be noticed by someone not in the know. Those indicators look awful, put the originals back! There's nothing wrong with the standard bike, leave it alone.
Why talk over the fly bys?
Really? Have you swapped the most beautiful indicators in the entire motorcycle industry for these cheap plastic things?
Don’t know about beautiful but agree that TEC Chinese rubbish is naff
Just buy a more powerful bike in the first place?
why? people bought Norton and BSA and RE and modified them and got them in to the 100mph range. Also the TT was full of stock bikes that owners modified, them you got bikes like the Manx norton, AJS, Velocette, etc etc
If you want a fast bike sure, but you don't get the point, is not just about getting a fast bike, some of us enjoy modding a bike. But ya, if you just want a fast bike, buy a faster bike.
Some enjoy modding as part of the hobby
I gave your comment a thumbs up before thinking about the changes I’ve made to my 79 z1000. I’m such a hypocrite.😂
@@ark1289 plus what some noobs don't get is the bikes run so much better after doing these types of mods. It's not just about numbers on a Dyno sheet.
I keep trying to tell people that unless you’re going to change the cam, these mods are useless. The stock intake and exhaust are engineered to work with the stock cam.
I wish they would do an 865 big bore hi compression ,cam,exhaust& tune
Except that the bike will be running cooler and likely smoother and less snatchy at low speeds. I'd take that without the little power bump.
@@sd3457 I do think the fuel X lite may be worthwhile.
@@sd3457the bike fuels beautifully stock. This result is the same as most of these Enfield mods. It’s louder with more intake bark so you think it’s faster but it’s making bugger all more. If you’re serious you need high comp pistons and a cam or go crazy with the 865 kit etc.. then you are spending as much as buying a second bike as you could just get a speed twin 1200 and blow it away.
@@sd3457yes, some one who gets it
