there is plenty of potential in a serval.  the just take a real "builder" to get the power out of them..

 

0h yea  i rember the old days.  you had to actually know a thing or 2 to have a decent motor.  not jsut buy a "clean up ported" 421 CUB and all of a sudden you got WOOSH power

Who's running one and what's your set up carbs, swing arm, and pipes?

I've got a 4 mil Serval, 35 mm carbs, V-force II's, CPI's, 4.5 timing, Redline domes, 6" swing, 22-11-8 11 paddle haulers.   I love it!   Great dune play bike.

Forgot to mention that I had Cameron at Redline touch up the porting, and I'm running 92 non-ethanol.
