The results?

3 laps in...





The reason?

Plugged pilot, and floats set too low.

Lesson learned... Next race build, we will have the carb, check the jetting, and break the engine in.

Yesterday we received a 91mm CR500 Wiseco piston.
I took the cylinder and piston to the machinist and told him the specs I wanted it bored to. I should have it early next week.
We will be getting the Kart this time so we can tune it and break it in over a few days.
I can't wait....

Race results.
1st heat placed 1st.
Second heat placed 4th.
Main was in second but spun out. Had to start over from the rear of the pack, ended up placing 3rd but was DQ'd due to a early restart that everyone says was bunk.
Oh well, that's racing.
Overall I'm not dissatisfied with the results especially considering that we have a lingering lean issue.
We think we know the cause but will get it resolved next week.
We do have two weeks before the next race so I'm certain we can get this figured out.

Special thanks goes to Adam Millar for his technical support.
Without Adam's help I'm sure we would have finished at the back of the pack....

Unfortunately we were too busy trying to figure out why we were having a tuning issue..
We think we have it sorted out but will have to verify next week.

That is awesome! I used to race karts but was in the 100cc Yamaha and 5 HP class back in the 80's. Fun stuff!

If so.....  :evil:
