New Parts
 
Well i just installed new performance CDI and new Mikuni 30mm carb runs much better now..pulls wheelies no problem just need some pointers on fine tuning carb it seems to wanna stall out unless i give it gas

Are you saying it doesn't idle very good? Does it get better if you add choke?, could be the idle is a bit lean, try turning your A/F screw out a 1/4 turn or so, if your more than 2 turns out then a bigger pilot jet is needed.

For reference, the 30mm carbs i've seen come with a 20 pilot and 100 main jet installed, most of the people with 200cc beasts on here have gone to a 110 main and 25 pilot with good results.

Adjusting the clip on the needle jet will help your midrange, idle is controlled by the a/f screw and your pilot jet, what happens if at 25 seconds in you give it a hit of choke, will it keep running?, if so then your too lean, open the a/f screw more, remember if your more than 2 turns out you need a bigger pilot jet, as mentioned before your carb should have came with a 20 pilot in it, most of us are having better luck with a 25 pilot jet.

Yep, should be on the bottom of the carb close to the intake manifold, turning out is richer, turning in is leaner.

They are all the same length, they are measure by the hole that is in them, so the 100 main you have will have a 1.00 mm hole in it a 110 main would have a hole that is 1.10mm.
Jets are cheap, but as mentioned before your new carb should have came with a 100 main and 20 pilot and i have suggested what other members are using which is the 110 main and 25 pilot, most of us have done all the upgrades though, cdi, mikuni carb, UNI air filter and some exhaust work.

Does your carb say mikuni on it?.

I really need help... im not sure what type of jet to buy .I know i want a 110 main jet and 25 pilot . Would my best bet be to take the whole carb to the parts store and have them match them...i just tell them what size i want Right??
