Still on that 4 stroke honey moon SF?
I encourage rider/owners of performance 4 strokes to call and talk to some engine builders, go to a race track and talk to pro riders/riders about the life of there motors and the cost of a rebuild and frequency of there builds. Piston Life?
1) Cascade Innovations = Chris
2) Redline Racing = Cameron
3) Grand Prix cycles
4) Albany Supercross track , Albany.
Banshees were in production here for nearly 20 years . There is alot of used parts out there, helps on rebuild costs.
On the performance side of cost, a Cheetah cub cylinder is more in line with a 4 stroke head replacement cost wise.
2 strokes are faster and easier to work on, and even the book says that.
If you do all your own work that helps alot.
Some manufacturers have a 50 hour replacement interval on there 4 stroke piston, at the track one pro has taken his piston to failure 2 times right at the 90 hour mark on his 4 stroker. As for power increase for the buck the 2 stroke gets more.
I'm not beating up on 4 strokes, just spreading the word on maintenance costs of a 4 stroke. The Honey moon is over now and many people are having to rebuild them and its not cheap. And with the economy like it is .......
See this at the shops/track and my Friends that have done motor work.
