MILO Posted January 6, 2007 Report Posted January 6, 2007 when i fire up my shee for the first time for the day, if i let it sit and idle to warm up, it will foul plugs. if i jump on her and take off but baby it till it's warmed up, it will foul plugs. will just adjusting the air screws fix this?? i'd like to be able to start it and let it sit and idle to warm up. current set up: pc pipes - pd pro flow(foam)no lid - v3's - wiseco pistons on recent rebuild - noss head 20cc domes - 370 mains - needle 3rd clip - stock pilots - air screws 1.5 out - elevation 1200 ft.

I would first down size the main to like a 340. I think you are running WAY WAY too rich but I could be wrong since I don't know much about NOSS heads...That could be your problem. I'm at 400ft elev. and I currently have a 340 in mine and I'm really rich. i should have a 310 in. Did this start happening right after the rebuild?? Quote
MILO Posted January 6, 2007 Author Report Posted January 6, 2007 with my set up, plug chops didn't show a thing until i got up around 360's. after the v3's, noss head, and rebuild, 370's looked better on the plug chop. shee's as smooth as could be on the top end too. i've had this problem before the rebuild though. it runs great bottom to top, idles great and so on when warm, only have this problem on cold starts. :shrug: Quote

Found out that it was my stator. it was really rusted around it. And it was bent. If you have a multitester you can test it. You only have to unhook one cord. Or maybe pull off the side cover and look if the flywheel looks real rusted. Quote
dajogejr Posted January 6, 2007 Report Posted January 6, 2007 Just goes to show you no two bikes are the same. You should end up with a 290 to 300 main in that bike with those mods and that elevation. However... If you are in fact doing the plug chop correctly, good for you...for getting it correct yourself. Check the float level to make sure it's not flooding with too much gas... Check all the electrical as said. Hate to say it...but, check compression as well...just to be safe.... Quote
MILO Posted January 6, 2007 Author Report Posted January 6, 2007 last time i pulled the cover off, my flywheel was pretty rusty looking, but i don't have a puller to get it off right to check things out. i guess i had better get one. we'll ride in pretty wet conditions often and thru some creeks so it's hard to keep it clean in there. i'll have to double check the floats too. thanks guys.
