I've tried the knowledge vault, but can't seem to find exactly what I'm looking for.

Situation: 2003 XB9R with 54k on the clock. Bottom end rebuilt at 44k, but now I have a knocking crank rod bearing.

I'm wrestling with what to do. My choices are:

Used engine ($1k-$2k)
Have the dealership replace the crank ($2.4k but "done right")
Replace crank myself with lots of help from friends. ($1k in parts and up to $1k in beer and pizza)
Sell the bike with the knock at a serious discount and buy a new Buell in an attempt to regain reliability and peace of mind ($6500 minus ~$2k for my bike).

For the record, this is the first bike I've ever owned, and I've always dreamed of parking it in my living room at the nursing home when I'm old and gray.

How hard is it to replace the crank in one of these things? Are there lots of special tools required? Do I need more than a new/used crank, new bearings, and an engine gasket kit? With this many miles, should I replace the clutch and transmission too? Does that drive the cost to the point of unreasonableness?

Sorry, I'm kinda OCD to begin with, and issues like these do not play to my strengths.

If you plan to keep the bike that long, get the shop manual and see what you think about doing it yourself, or bringing sub-assemblies to a Buell dealer or independent shop for special tools work.

I say buy the manual and do it yourself!!

It is instructive!!
And when the job is done ,and everything is right it gives a good feeling that you managed it yourself.(specialy when you old and gray at the nursing home)

when you disassemble the bike/engine label and mark the parts you have to or even take pictures ,it,s a big help when you rebuild it.
Check the tolerances and replace when necessary also put all new bearings in.
And take your time for everything don,t rush it.

Maybe someone near you with technical knowledge can help!?
So keep your mind on the job.
Don,t rush things and when you rebuild the engine keep all the parts very clean!

Good luck!!
