How long will a BB engine last before having to be re-built?



Bill Gately says a Wiseco'd 904 should get a fresh honing and new rings at 50,000 miles, but he pulled his apart after 30-40,000 and said it had enough wear to warrant fresh rings. This is after he beat the hell out of it and did dozens (if not hundreds) of dyno runs which are very hard on the bike. He is probably harder on that bike than any of us would be on a rented ford festiva.

If you do it yourself and are mechanically inclined...you wouldn't be put off by having to revisit it for a rebore after 40-50k miles. It's like tearing down your old shotgun after a day in the field. It can easily be torn down in one Saturday, and rebuilt the next weekend, provided you ordered your gaskets from Bikebandit early enough, D'oh!!!
