Hey guys, Long time reader, first time poster looking fro some advice. I bought my son a 2001 Blaster for Christmas. FMF gold pipe and air box lid delete. It ran ok besides the carb leaking. SOOO, I rebuilt the stock carb (.230 main jet) and finally got the float set to stop the overflow leak. It ran good for a few weeks, never idled great...As usual, not being able to let well enough alone... I ordered a new carb off of ebay and jet kit. I also ordered a pryamid reed block. Long story short and 4 cheapy carbs later, multiple jet changes I have the stock carb back on with original jetting. The problem has been a midlrange pop (seems lean to me) with all configurations. Cannot get to WOT it is so bad. Bottom end is ok. I have done a crankcase pressure test, 6PSI for 8 minutes, no leaks. I even went back to the stock reed block, same problem. Original main jet is .230, 32.5 pilot, and needle in 3rd clip. I have went all the way up to .340 main with no real change. Compression is 100psi. Any advice before I send this thing to the Yamaha shop and waste alot of money?? Also, I'm in Houston Texas. Pretty much sea level. Thanks guys!!!
