8v92 6v92 two stroke basics

[Gregory OConnor]

Don, Nice to see you and your wife in Riverside today. Your
electronics are quite impressive. The size of the dish make your
bus look like a VW Camper. You missed a great lunch even though Tim,
MontyH, DerekH, and I were asked to leave the restaurant befor the
desert cart was shown.

the start of this thread is a repost of info forum member jimS
posted on irv2. Below is a snip I refered to about slober path
maintenance. I didnt want to hang around in fear that the CCW tech
would take the time to answer my question on your dime. This may be
a good question to pose to CCW in Q as they see V92's with major
miles. There were pics of Brian???? 94ish pt someplace with major
blower box sludge oil repair. I always wondered how to avoid the
buildup???????
