Interesting... When I replaced the head with the modded one and cams, I inspected the bore and piston and they were perfect after 1500 miles. A few hundred more and they are trashed. Do you and Bill agree that the failure of your rod bearing led to the failure of your piston and cylinder?

I guess it doesn't really matter to me since I'm cashing out, but it's always nice to know why things happen. What did repairing the big end bearing entail?

 

Will a gen 1 engine bolt up in this frame? I have a Gen 1 with less than 1000 miles on it, but it is from Guam and I can not get a title for it!
If my motor will work, I may be interested.

As far as I know, the engines are identical. Feel free to PM me if you have any questions.

would you be willing to haul it to Atlanta? I'm in FL but I would meet you there.

 

Sent you a PM

 

PM sent!

Thanks

 

There are some differences in the wiring connections between the engine and frame harnesses, IIRC

 

Bike is sold.

Thanks everybody for all the info on the forum here. Enjoy the ride!

 

When the bearing fails you get a lot of metal floating in the oil and since the piston is splash lubricated it's washed down with a nice soup of grinding compound-explains why the bore is trashed. The only way to repair the rod bearing is replacing the crank-no aftermarket parts will interchange.
I have over a year on it since the rebuild and it has been flawless. Bill was very helpful and he sources quality parts-the only thing that I wish he would consider changing would be to use a dry film coating on the piston skirt to help with longevity. It's a pretty big slug with a fairly short skirt so thrust loads could use any help they can get.
