HC head install update

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

Nice improvement where...low end? Overall?

Thanks

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.

Did you do the OKO carb mod?

no i havent, im not that sold on it yet. none of mine have the problems thats going to fix. maybe its a mistake and i need too,i bought the bits to do it. i do also have clutch springs and reeds coming.

thanks for the help,keep it coming

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.
