I'm trying to get my Son's buddy's 96 600 running proper.
Here's where the problem starts. Kid leaves the petcock on prime. Gas fills crank. Overflow of gas and oil on floor. I've done the drain of crank case and put in new oil. Engine seems to have survived with little to no ill affect.
This was last summer. He informed me that the bike just hasn't ran properly since then and has gotten increasingly worse. Now it won't idle. Idle screw has to be turned up to about 2200 rpm. Let off and bike drops to below 10 and then slowly fades and dies. There is no levelling off of idle between 10 and 22. It jumps back and forth, above or below when idle screw is adjusted.
I just started tinkering with it over the weekend. Here's what I've done thus far to carbs. (All stock) O-rings on floats replaced. Floats set to approx 14.5 mm. Diaphragms checked out ok. A/F set at 1 7/8th out. Carbs were sync'd at the 2200 rpm (Yeah I know, too high. Wouldn't idle at 18) and they read equal across the board.
Engine sounds and runs healthy in upper rpm ranges. There is a hesitation when throttle is blipped.
Before I cashed in Sunday I took the carbs loose from the intake boots. There were small puddles of fuel. I do not have any overflow out vent tubes of fuel. Equal amounts in all cylinders.
Here's what I'm thinking before I go over there later tonight. Is there not an o-ring under the piston valve? ( the white piece in the center) Vacuum pulling in just enough fuel to flood out engine?
Any other ideas are appreciated.
TY
