I got 200's and 25's..What u recommend now?

[BansheeNigg]

My 1990 shee has been bored .80 over with weisco pistons, boost bottle, pro circiut pipes n silencers. now that its winter its running REALLY hot and backfiring, so i pulled the carbs today and it has 200's and 25's. What do u reccomend i buy to get her running good? By the way the average temp around here is 30 degrees so keep that in mind too. Thanks

wow, you should be at least in the 300 range and maybe even a size up on the pilots, unless you're waayyy up in the mountains.

Are you running stock air filter?

id guess 27.5 pilots 300 mains needle in middle, do a plug chop then report back

sounds like a good starting point. my mods listed in sig., i have 320 mains and 30 pilots. shee is on the rich side, but your 200 mains have to be way lean. where are you riding at?

[05bansh]

Waaaaaaaaaaaaaay to lean!! Jet up man!! Start about 300 on the mains and 27.5 on the pilots like everyone else has said. You will notice a huge difference in how much better shee runs after you get her jetted right.

[richybanshee]

Way lean .. that is why the shee overheats and backfires.

 

If airbox lid is on, snorkle removed, probably 280-300 mains and 27.5 pilots.

 

If airboxlid is off, 300 or more, 27.5 - 30 pilots.

 

This is a great STARTING POINT, I can not predict the correct jetting. You may have to do some test before you get it right.

You are lucky it still runs at all , suggestions above all look pretty good for starters.

LIke everyone else suggested. 300mains, and 30 pilots...run it too long like that and you'll be changing pistons and rings also.
