How often between rebuilds?

[rruser350]

I was thinking about picking up my first banshee this winter and had some questions.

 

I noticed a lot of posts dealing with having to rebuild the top end often. I could see this happening on modded out engines but is this really as bad on stock bore/stroke engines?

 

Would replacing the rings before anything bad happens lower the risk of needing a bore/ new pistons?

 

I have seen a slightly modded banshee (ported, reeds, larger carbs, milled head, pipes) be put through hell for close to 3 years without a rebuild yet. Is that the effect of well built engine or just luck? maybe both?

 

If it helps, I would be putting less than 500 miles a summer on the quad and maybe some snow riding.

Any high revving 2 stroke will naturally beat its self up....how bad it gets depends on how hard you ride, maintance schedule, conditions, ridier ability, premix ratio etc....and an engine that makes more power has a tendency to be harder on itself.

 

If youre going to replace the rings, then you already pretty much just rebuilt the top end. Change the gaskets and you'd be good to go.

 

I rebuild once a year, I keep a tight maintence schedule and mix my gas the same every time, and I beat the shit out of it. I have never (knock on wood) have had ANY major failure yet. but yeah you could go 2-3 years w/o a rebuild....but wjy take chances.....

Yes, I don't mind having to put new rings in every year or two. I just don't want to dump $200 on pistons or a bore that often (i know it will be needed at some point)

That not a whole lot of riding. I would say that a typical ported/piped motor could easily go 3 years on one set of rings. Just check the compression every so often to make sure the rings are still sealing good and check the bore when changing rings for clearance to ensure that you don't need to have it bored and go up to the next piston size.
