I bought this bike about 2 weeks ago from some guy who said the bike runs great.. yeah right!! The bike started right up cause he had pre warmed it up right before I got there and it ran fine the short distance I had to ride in which was a short gravel alley about 1000 feet long. It'll bog when you first take off.. Low to mid range is very powerful but it'll bog write before the power band kicks in. If you're in the bog at WOT for 5 sec or more you can feel the power band kick in for a moment but not as it should. Sorry if this sounds stupid to you pro's out there. It's an all stock 2003 Honda CR85r other then a FMF silencer and here's what I did so far: Drained old gas and put fresh 40:1 Amsoil Dominator / 93% octane gas mix.. Installed new fuel line. Disassemble/Cleaned entire carb with carb cleaner. Has stock 125/50 jets with the needle clipped in #2 stock position and A/F screw at 1 5/8 turn.. Floats are at 19mm.. I'm 692' above sea level. I tried leaning and richening the A/F with no luck getting all my power back. New pre oiled No-Toil air filter There was some spooge coming out the silencer so I repacked the FMF silencer with the FMF (white) packing.. Packing isn't too tight but not loose at all.. The Old packing was burnt up and had lots of unburnt oil in it. Compression is at 120 psi.. Is this low..? New NGK Iridium BR10EIX plug.. Factory gap is .006-.007mm This Iridium is gapped at .028mm. I read somewhere that you don't gap Iridium plugs.. Is this true..? Or should I gap it to spec and try it anyway.. Also I know this isn't the proper way to do a plug chop but after about 5 mins of riding mostly at WOT the plug had brown tan looking color on the porcelain. All frame grounds was cleaned to bare metal and used electrical grease on all connections. New Boyesen super stock reeds. Strange thing is after installing the reed petals and on one side there was less than a mm of a gap. Could the reed cage be bad..? Drained trans oil which appeared to look normal and changed it with Amsoil 10w40 motorcycle oil.. It does have an exhaust leak at the manifold but not really that bad. It seems to have good spark.. I wasn't able to do a leak down test cause I can't afford a kit right now but I did take starting fluid and while it was running I spray all around the carb and boot areas with no change in idle speed. So far this is everything I've done with no changes in performance. What do you think the problem is..? Or what other things should I try.. Thx in advance..!!!
