Hello,
I'm hoping you guys might be able to help me out on this one. I read thru many forums on this topic and I'm more confused now than when I started. So here's my problem:
My 2002 GP1200R runs great on the trailer (revs up to 7,000rpm), but not in the water. It only revs up to 5,000rpms and maxs out around 30mph. It is very slow to start and will even stall out if I try accelerate too hard. It takes patience and plenty of feathering to get this thing going. It almost feels as if the intake is clogged, but it is definitely clear and the choke is not engaged or sticking. During the run, it did take off for a split second and nearly ripped my arms off, but only that one time.
The previous owner removed the catayltic converter and installed a D-Plate. He also had the carbs rebuilt this past fall. I did a compression test and all 3 cylinders a pushing 120psi consistently. I checked the fuel filter and lines and everything appears to be in check. All 3 cyclinders are getting spark, but it runs the same when I pull the plug on the 1st (closest to the bow/front of the craft) and not with either of the other two. I have already started by pulling the stinger, exhaust camber, and stock flame arrester. I haven't pulled the carbs yet, but I can see oil present in all 3 with the most pooled in the 1st cylinder. Does anyone have any advice on where to go from here?
