NEVER HAD a problem starting in fall
With exception of the POS '80 SRX, NEVER HAD A breakdown
Never Had to work on a SUSUKI engine, notice the high miles, never did a ring job.
Back to the topic:
I think you are SOL Several things you could have done after the shop to cause the problem.
I treat with seafoam and fuel sabilizer, run engine until hot (feel heatexchangers). On two strokes, put oil in spark plug hole, slowly turn over a few times, put more oil in. put plugs in and turn over again. Drain treated high octane fuel out of tanks and put into '87 GN.
I disagree with the heat and humidity aspect on a carb sled (more so heat). The carb is not jetted to run in warm temps and will foul the plugs MUCH quicker! That is why my 2 smokes I never started until late fall when cold outside.
On the last to 2 stokes, I changed the plugs once... at 10,000 plus miles. Only because the sleds had 10,000 plus miles. With the exception of running 7 gallons of diesel in the 800 triple (never let your friend fuel the sleds), never fouled a plug in a Susuki. (by the way, I did burn the diesel through the sled, had to run with the choke on)
Check my stats, I might know a little something. I also solved two problems with the '09 Turbo's that mine was in the shop 4 times to get resolved under warranty. I'm sure my royalty checks will be in the mail soon from Cat. (yea right)
