Cheers Rob - really useful. I was getting some spluttering when accelerating and you commented about the needle on the PHBL being a bit small, so I put the clip on the top groove and it’s accelerating very smoothly (SX200). Amazing how such a small adjustment can make such a big difference. 👍🏻
Thanks Rob, really appreciate this one!!! I got a 175 kit with the same exhaust and carb, but way different jets. Not running that well, I should really get it on a dyno. Interessted to hear how you guys come along on the jetting, once its on the road.
Nice to see there's a method inya madness & tbh a good idea with airfilter rod & nut. I'll be interested in running results using this carb. Cheers Rob 👍🏼
HI Rob Sorry another question. Did you use a special inlet manifold? The reason I am asking is that I fitted a BGM RT 195 Kit. The inlet manifold I am using with the carb means the throttle cable foul's with the toolbox as it seats to high on the manifold. In your vid it sits, I would say in the correct position. I think I may need the BGM Inlet manifold for the kit, but do not wish to buy it is it does not make a difference. Any thoughts. Cheers. Excellent vid by the way.
Hey Rob, I'm doing a jet 200 at the moment and I'm thinking of fitting a PHBL carb, is there any real reason to change any of the jets etc from how they come out of the box? it's a standard 200cc inlet manifold, wonder if you can advise , cheers Ken
Hi Ken. You definitely need to jet to suit your scooter. We don't actually know which machine these are jetted for in the first place. If you are worried about doing it yourself then any reputable scooter dealer can fit the correct jets before sending it out. Mb, chiselspeed and many others.
Hi Rob been waiting for this one good tip about the wing nut very clever check out the jetting on MB website for this carb it says with air box and filter main getting92 90. 88 with remote98. 95. 92 no filter 105. 102 100 I’ve gone for the remote option and it’s flying 👍👍
That info is slightly outdated. With the bgm filter and the elbow removed in the filter box it's supposed to be about the same as with a remote filter but we will soon find out.
Rob, have you ever fitted an extra throttle return spring on the throttle control rod? My dellorto will not return to tick over position without my assistance?
I've never needed to fit one. Your throttle rod is probably rubbing on you cables in the headset or the twist grip tube needs cleaning or re lubrication.
Always wondered about the drain tube on the air hose. I get that it is there to drain fuel from a flooded carb, but doesn't it risk sucking road grit up the tube into the engine?
The air hose being at such an angle is going to cause future problems I suspect. I am glad I didn't use an air box on my rebuild. I have a ram air filter on mine, it looks good if not original but having the hose at an acute angle doesn't look original either. Its all about compromise sometimes, originality against usability. Looking forward to seeing the TV fired up and on the road.
Hi Rob would you use the same carb and set up with the air box on a 225 RT kit as I would like to keep the original look on my SX 200 and to keep the noise level down thanks 👍
It is really restrictive through the air box. The chap with the blue TV has fit a bgm clubman sport and a open 30mm phbh and it's much quicker without being obtrusive. If you look on my story on Instagram you will hear what a open carb, bgm clubman and rt sound like. It's actually quite pleasing to the ear.
Hi Kickback did you have to reset this set up, as previously you only ran in cold weather, just follow up from our previous correspondence, cheers mate.
I have a 25 mil carb on my 186 kit and has been running great for the last 3 years. All of sudden running crappy won't stay idling. Took carb apart and noticed one of the floats is full of fuel. If you ask me there shouldn't be fuel in there but what do I know. Can anyone answer??? Thanks
does anyone happen to know if the main jets are 5mm or 6mm? I've got a dellorto jet kit from my scooter and wondering whether they'd be interchangable on this carb (different bike). Thanks in advance :) [edit] nevermind, jsut found it, M6 (6mm) apparently..
ok rob...just finished dry build on 195 rt on 125 series 3 dellorto 25 mm 100 mjet 42 clubman exhaust bgm 12v ignition...have spark...cannot get it to fire and fuel seems to be in barrel... ideas? thx
@@kickbackgarage hmmmn great Q ill check, i think 70 is stock? what should it be? or is it arbitrary to the running condition at the present? thx again!
Hi Rob how did this run with the D26 needle, I have just used the RT kit same set up with D22 needle runs really well, slight stutter1/4 to 1/2 throttle, it’s hard to determine whether it’s rich or weak at the present, maybe a slighter reacher needle taper may just iron this out. Thanx
@@kickbackgarage thanx for the reply yes airtight, when I say stutter it’s like one misfire then ok again, does it consistently at this position, maybe rich but the D22 is a weaker needle than than the 26, thanx for your reply , interesting videos.
@@kickbackgarage yes the through the air ox with neck opened up, and the gause type from MB, I may try dropping the needle it’s on third clip down may try moving it up to 2nd before I try the D26 needle, the engine pulls nice except for this blip,
I think the safest way to determine if it's running rich maybe actually to try it a couple of steps richer. If it gets worse, then you know which way to go without running the risk of trying it too weak.
Alright mate i am from hull and have rs125 aprilia with 28mm vhst but its impossible to jet so got the 34mm silver top dellorto but putting bike back standard mick abby did a fast road tune on it what i need to know is all 28mm phbh carb same jets roughly anyone you know near hull fancy so work on my bike i will pay top rates i am terminally il but can guide them
Damn i bought one came with a main jet 116. Working my way down now at 75, still not running as it should. Its way to rich. 172cc malossi on a Runner m07
Edit. Back on 110. The float level is off it keeps overflowing. Small 5mm jet was a 100. Changed to a 45 runs smooth on 1/4 to 1/2 Are these notorious to overflow?
Batman would know that the top clip position is 1st then downwards is 2-4 from top. When you move the clip down you richen the mixture because you lift the needle up.
@@kickbackgarage haha yes bud i was just wondering how to access the needle as i wont be fully removing the carb rather just working on it with the top seat removed (rs125), cheers

@@WarpVisuals in the 1980s i was using AMEL and dellorto then in the early 90s i move to Mikuni and keihin which had better performance from the flat slide carb , finally settling for the keihin because of its D slide making better atomization but also keeping some of the round slide advantages ...... now i see people like ERIC COPE using the same carb on his silhouette race bike at elvington with a great top speed of 127 mph need i say more ?

Hi Rob what is the main cause of fuel spiting out of the dellorto carb with no filter at high speeds😊😊
Tip, use electrical heat shrink where the clip touches the paint:).
I know. Your the 3rd one to mention that 😎
Kickback Garage the funny thing is, i know you know this😂
Hi rob
Scooter center do a dedicated head cowling for the rt kit and the armadillo air hoses have a drain on them .
We know but they didn't when we painted this.

I've never needed to fit one. Your throttle rod is probably rubbing on you cables in the headset or the twist grip tube needs cleaning or re lubrication.
Hi Rob When you fitted the carb to your scooter did you use the standard throttle cable and choke cable or did you have to modify?
Standard. But had to modify the choke cable a tad.
Always wondered about the drain tube on the air hose. I get that it is there to drain fuel from a flooded carb, but doesn't it risk sucking road grit up the tube into the engine?
Not really an issue. My engine has a breather that is basically a tube. No need over thinking these things.
The air hose being at such an angle is going to cause future problems I suspect.
I am glad I didn't use an air box on my rebuild. I have a ram air filter on mine, it looks good if not original but having the hose at an acute angle doesn't look original either. Its all about compromise sometimes, originality against usability.

Hi Rob would the jetting be the same with a remote filter or with no filter at all 🤔🤔🤔 thanks if not the same what jetting and needle would you use
Almost the same with a remote filter. This is a slightly rich starting point 😎
Cheere for that Rob, I'm fitting the choke cable kit to my phbh26..do you have a video for that, or one you can recommend.
Cheers, Joel
No, sorry.
@@kickbackgarage Cheers for the reply 🍻
Does the fuel intake banjo need a seal between the black plastic banjo and the carb housing?
If I remember rightly, it seals on the filter.
@@kickbackgarage ok brill thank you, also any ideas where to get a carb rebuild/main seal kit from?
Eurocarb
air tube looks far too cranked over, surely it will crack & split in time. is there any option?
Maybe a different manifold would move it over. Will probably last a couple of years though. Probably a good idea to have a spare in the toolbox.
Hi Kickback did you have to reset this set up, as previously you only ran in cold weather, just follow up from our previous correspondence, cheers mate.
No. This scooter did 860km this weekend on these jets.
@@kickbackgarage yes I saw your photo on the RT site and it made me wonder, good for all subscribers to know this.👍

You are correct. New float needed.

[edit] nevermind, jsut found it, M6 (6mm) apparently..
Yes, m6. I have a small bunch of m5 wrongly bought 🤣 the smaller carbs are m5 so that's why they are listed as main jet. 🙄
Hi Rob what’s the benefit in performance of using a larger needle D26 in your carb just interested thanks
I have no Idea! 😂 It's what mb recommends after many hours on dynos on the Rt195.
Did you drop the banjo on the carb vertical to get that nice loop.
Eurocarb in the UK sell loads of different angled banjos.

It actually runs fine but the climate here in Norway dictates slightly rich settings. I would suspect stutter being rich if the engine is airtight.
