Thanks for the info. I saw the oil by-pass by Mr Turbo. seems like a lot of money for a bandaid. is it worth the $300?The only internal oil bypass kit I'm aware of was sold by Westech (link below). But I think they do not make it anymore; it is not on their website.

Beside this one, I only know about external kit that are (maybe "were") sold by companies like Mr Turbo or Orient Express.
This being said, they are not a cure for #3 conrod mishap. They lowers the odds but it can still happen. There are some "patches" that can help but the most important/efficient are:
- Keep oil level at the top of the sight window (even if it's above the max recommended level)
- Avoid wheelies
- Avoid long extended high speed & high RPM riding
Other (but less efficient) patches are:
- Use the latest design of oil pressure switch (I think it was introduced on 1993 D model, maybe 1994 but again, I'm not sure). It allows a slightly higher running oil pressure
- Port inner of internal "I" tube and "J" tube
- Remove balancer (not a great help though...)
Hope this helps...
I also think it's expensive but Westech internal kit was the same price. If you want to get the maximum possible protection and want to help your peace of mind then, yes, $300 could be worth it. Personnally, being kind of a sedate (and cheap too...) rider, I am instead "investing" more in the top three advises (high oil level, no wheelie and no top speed run for long period). But that's just me...
Also, because you intend to take your engine apart anyway, porting the oil tubes and matching each bearing hole with oil passages will be free added insurance against failure.
Finally, if you really intend to invest in a lot of go-fast parts in your engine, maybe the $300 Mr Turbo kit makes more sense to avoid a possible failure that could junk some of those expensive parts... But it's your call.
