I got the new head on and did a comp. check and its about 170-175 with a 100 main jet. I havent changed the fuel yet but its a nice improvment.

If anyone has anymore ideas for this wc drx 90 please do tell.

Thanks Ken

low end mostly, we run against modid apex 100. we need all we can get on a shoe string budget. to many quad and not enough sponsors.

the compression you have now is perfect! This is what the DRR was lacking to get them up to speed. Im glad to hear it went well for ya.
