Wow, Is that normal??

[Rick]

A lot of guys looked at it and told me I'm running it really rich. I guess I'm paranoid about blowing it up. :evil_lol:

I'm replaced the top end and will probably lean it out for the next couple of races.

Complete top end cost me $80 and took me about 3 hours to do. I am also changing the reeds with the good ones that cost $94. And from what I've been told, the better reeds will last longer as well.

So far there haven't been any problems at all. Aside from the plumbing of the dual fuel pumps, everything else is really easy to work on and maintain.

We'll see how it holds ups for the rest of the season.

Thanks for posting that Rick. What jet do you usually run? I've been told in the 60s for sprint and 70s for road racing.
What kind of reeds are you getting?

[Rick]

I've been running a 170 for the main jet and a 58 on the low speed this whole time. But I think I've been running it too rich as you can see in the pics.
