4 and 2 stroke maintenance

[SANDDEMON]

I encourage rider/owners of performance 4 strokes who have not done motor work yet, 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= Mike
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.

Wise words SANDDEMON.  I've been saying that for years but not enough 4 strokers were wearing out yet...

[SANDDEMON]

Senator,
yes they are wearing out now, and the repair bills are huge. Talked to Cameron last weekend about this, a customer waited about 5 years to have Cameron go thru his 4 stroke. He got a  New top end , piston, crank and cases.....$$$$$$$$$$$$$$$$$$$$
There starting to need rebuilds................and they are expensive rebuilds.
Preventive maintenance goes along ways.
Change oils often, filters too.
Keep your air filter clean clean clean. A little dirt/sand on the valves hurts them. They get hard to start and then $$.
