Hi
Looking for a little help with my carb set-up. Bought a GTS with a strange carb set-up - there was additional smaller tubes and what looked like an additional pump that worked off a cam system. I had a spare of stock carbs and replaced them.
The carbs work great at idle and up to about 75%, but there was a few small and one great big backfire above the 75% although it will run for a time.
Went back to the original carbs and the high speed screws were about 1-1/2" turns out. Everything appears to be stock on the ski.
Another note - There was no water reg valve so put on in.
Any thoughts? I am guessing lean on the high but why would that be the case?
