Guys... im at a complete loss here... i have 1 or 2 previous threads on my issue and to keep it simple i created a new one thats up to date with all the stuff i have tried to fix the issue. il leave them up unless anyone objects so maybe the information posted may help someone else down the road.
HERES WHAT I GOT FOR YA:
TORS delete
parking brake delete
oil injection delete (mixing 32:1) and (oil port on carb is capped)
finally got a genuine mikuni. my previous diagnosis was that it was running lean so i upped the main to a 240
has a different silencer. i was told it came off a dirtbike.
Air box cover is gone.
although it does need a new filter, for troubleshooting purposes i cleaned the hell out of it and rinsed it with gas several times..
Things i tried:
new plug
cleaned the power wire to the coil
adjusted the needle (its now 2nd from the bottom and it didnt help at all
new fuel line with no filter (to promote the best flow possible)
checked the float. its fine
checked the petcock. its fine.
checked the gas cap vent. its fine. although it had a decent amount of resistance to it, it shouldnt be free flow should it? i drained the tank by just taking the line off the carb and letting it drain into a gas tank and it had plenty of flow. drained the tank in a little over 5 minutes
AS OF NOW...
the only 2 things i can think of that would be left is a case leak, or maybe the silencer needs repacked... i havent done either yet (i know i know.. leak down should be first) but i cant get my hands on a radiator pressure tester readily and when i get the chance to trust me... im going to.
the bike runs like it should up to about half throttle. once you get to half throttle it just falls on its face... then you let off the throttle back behind half throttle and it starts runnin again!
i know its a lot of information... i tried to organize the best i can but im at a loss here guys... next thursday im going to have a buddy of mine who is the parts dealer at JMP cycle come check it out and tell me what it thinks. every bone in my body tells me its a fuel/air mix issue and i just have no clue what else it could be?? i checked the plug before my most recent run and it actually had a really good color... and also, it idles great, and revs up great without a load on it.
side note: when i got the bike the parking brake sensor was already gone... but while i was replaceing the headlight, i noticed an orange wire with some sort of stripe design that was unplugged and i couldnt find out what it went to.. im thinking it went to the parking brake sensor but i thought there was 2 for that? could this have anything to do with it???
somebody PLEASE have the same problem i have and rescue me...
any questions at all please ask...
thanks a million in advance guys.
