MOPED ARMY

nothing major on the airleaks? get rid of all airleaks period.

Also make sure timing is legit.

that's exactly what you need to do. spray EVERYWHERE there is a surface change. carb to intake, intake to cylinder, cylinder to head, cylinder to case, exhaust. EVERYWHERE. have a friend help

How about getting the leaks resolved, ck the seals also, using a Estoril pipe and making a intake to accomodate a 16mm PHBG. Quite an upgrade and $ but it would work

why won't it idle?

when it dies is your plug soaked in fuel or is it bone dry?

What size needle jet is in your bing? if you have too much gas at idle and its a 2.22 try switching it with a 2.17

tccd + phbg + estoril is a really nice set up.

I think a lot of the idle problems come from using the larger 14mm bing. You may be able to better top speed out it but its idle circuit is too rich. In the wiki they call the jet holder which is weird but that part comes in numbers like a jet. I believe 14 and 15 bings run a 2.22. If you have others bings you might want to try a different jet holder but keep the same jet and that might help the problem.

Here at 77 we've better luck with stock cylinders we've had better luck 12mm bings and SHA's. They actually went faster and wanted to idle. I think it all has to do with the idle gas/air mixture.

16 PHBG is good choice too because you can tune them more easily. It's an expensive option though.

The intake port of the TCCD has about as much surface area as a 16mm carb, so any bigger than a 16mm delorio would be a waste unless you port the cylinder.

My bet is that you are just rich. With a Proma GP and and 14mm drilled out bing, and the stock air box (without the snorkel) I was running a low 50s jet. Pretty sure 54 was what we ended up with. And when it was rich it wouldn't idle, especially after it warmed up.

Also don't just time it to stock timing, advance it like almost all the way. If you have a meter and a timing tool set it to like 2mm before TDC. If you don't have the tools to measure it just advance it almost all the way. Timing is a huge deal with these kits, Me and GabeB turned his bike from a non-idling 30 mph turd to a decent ride in about 15 minutes by advancing the timing.

Then tighten up your clutch to compensate for the low end and you should be rocking.

Of course all of this comes after you have fixed any air leaks.

fixed it. Remedy= put on stock air boX. Idles like a dream now. By needle holder, do you guys mean the metal disk that clips onto the needle??

is your head on right?
