With the TM40 you can run the needle leaner due to the pumper aspect. Mine runs great at the 3rd notch and gets better economy than the BST. 50 mpg plus is easy to do.

Both carbs run the same main jet for the set up. My TM40 likes more out on the pilot screw though. I run it about 2 3/4 turns out compared to 2 or less on the BST.

So, if both carbs were set at 3rd notch, 150 main and about 2 turns out they will both run about the same above say 3,000 rpm... I'm guessing there. The TM40 will give better throttle response and pull at a lower RPM better than a vacuum carb. Thats it, no big HP gains, no squid go fast BS.

If your having trouble its probably the install or the carb is not set up like you think. If you did not verify needle position, main jet size and AP rod position then you don't know where your at. Many times its an intake leak, loose or ill fitting boot, a bad choke knob fitting, vent lines going up hill etc..
good info on set-up.

the carbs may be the same size but the TM flows a good bit more air at W/O throttle than the BST.

OK i sprayed around the carb with choke off using starter fluid. There was a slight increase in rpm but it wasnt huge. The thing is i have both manifolds on as far as they will go and the collars are screwed in as tight as they will go. I dont know how to create a better seal than that. How could I seal the manifolds better? Im also taking the bastard off to muck with the pilot jets.

jonkohl - good catch.

N.dica - can you post up a few pics of the TM40 installed? I'm not adept at tuning carbs but something on the install may look off.

I bet you have found your problem. I may not seem like much but it doesn't take much of a leak to mess you up. As far as getting a better seal; just go slow and careful. Clean an check the mating surfaces carefully. I have had a leak that went away for no apparent reason after I took the carb off and put it back on carefully. Could have been a tiny piece of sand or something, who knows. Good luck.

yeah i can do. Ive got her off at the moment to do a run through. One of the links said a guy used araldite to make a seal on his front manifold, but I didn't think I should have to use an epoxy to make a seal. The manifold on the bike is in good shape, and the rubber is in good condition. The nipples were cut off, and the carb was in fully and the ring cinched down as much as possible.. I thought it was supposed to come sized from procycle so I wouldnt have to use any sort of epoxy to make the seal. And if that is the problem- as the starter fluid indicated there is to some extent, i still dont know what the best sealing compound would be that wouldnt be problematic with future carb work.. I do not want to use an epoxy to make a better seal if I can help it..

Ill take some pics...

cheers

I think I found the problem!

Ok- so procycle puts a ring around the carb where it plugs into the engine head, basically sizing it to fit the rubber manifold of the bike....

I inspected that ring very closely and noticed that where the ring was epoxied onto the carb, procylcle missed a spot and I can see a slight bit of light coming through from the backside of the ring, MEANING, even with everything plugged in properly and cinched down, the vacuum leak appears to be coming from inbetween the carbureator mouth and the adapter ring procycle put on there. which no amount of refitting would be able to seal.

My question now is what kind of sealant would be best to put directly on the carb that will hold and block this space.
This is my next step and Ill see if this solves the problem before doing any more wrenching.

Hopefully ProCycle will step up and make it right. At some point I want to get the pumper for my bike, so I've been following this pretty closely.

Well, that would sure do it! I don't know what to recommend to seal the hole but I'm sure procycle can tell you what they use to glue the ring. Glad you found the problem!

Just hang on, they will be ringing in shortly for your solution I'm positive of that.

I have the Commuter..the question with windscreens is..Do you want the air to go over or under your helmet? I tried both ways..ended up cutting mine down, so the wind hits my helmet clean, but blocked from my chest..

Looks like Bergdonks links to comments about the rings paid off. Glad you found the likely source.
