you are right on the Yam 2 stroke. Most of the 490's had one plug, they may have made a year with twin plugs. So what the times look like to you all??

The times look pretty fast to me. Last week the hill was 200 feet, and the top time on a 250 was 6.9 secs. The top 500 time was like a 5.8 or 5.9. This is with a breaker though and it was a slow day, a little wet. But those times seem to be cruising to me. How good did you do? Were you the one talking about the kx 500 a lil while ago? Also, why don't you climb ur bikes. It's just a verticle drag race.

The one i have is air cooled and putting down around 65-70 HP. My dad builds the motors. Any other questions about it, just ask.
