dburnexx Posted June 16, 2014 Report Posted June 16, 2014 i am lookin for a little stronger reliable trail bike would a 421 serval stock lenght crank be alot more than my stock drag ported cyl im at 65hp now just curious if a stock stroke serval will put out in the 70s to 80s Sent from my GT-S5360L using Tapatalk 2 Quote
rjdgriff Posted June 16, 2014 Report Posted June 16, 2014 421 serval is a 4mm crank. Do a 4mm ported serval , you'll like it. Call redline 541-367-2453. Have your credit card readywhat he said. The 421 4mil serval is a blast in the trails Quote

Nightmare Posted June 17, 2014 Report Posted June 17, 2014 ok thanks will i need a longer swing arm Sent from my GT-S5360L using Tapatalk 2 That would depend on you but more than likely yes. I wouldn't go past a +2 for tight trails though. Sent from my HTC One_M8 using Tapatalk Quote
rjdgriff Posted June 17, 2014 Report Posted June 17, 2014 +2 would be good, I ran a +4 on my 421 and did fine but I think the +2 would have been great Quote
