compression is fine, leak down test fine, fuel pressure fine, spark fine, electronic box checked out fine, no sensors are showing up on the display as inoperable, valve clearance fine, chain timing fine. vaccume to all three cylenders is fine. bla, bla, bla....... MY PROBLEM IS........ with clutch disinguaged you can rev the bike to your hearts content, but if you fully pull the throttle quickly in sticks, stays at around 3500rpm's and lunges. If you then back off the throttle to about halfway it jumps up to the limit instontaniously. It does the same thing in gear, full throttle it lurches"jurks" off the line, back off half way and it pulls hard.I thought it was the fuel filter $200! so I cleaned the one I had out and it helped a lot. Before that it would'nt get any power untill you were at 20mps, I mean a total slug until 2nd gear, no power! Do I just need a new filter/pump? it's the only thing i can think of. it seems to have a sweet spot at about 1/2 throttle where it gets desent pull, but the more you pull after that it just gets worse! HELP!!!!!!! one more thing I noticed, the choke,when I pull it doesn't seem to increase the idle much at all, if any.
