Just to follow up for others that might have questions... I don't think this violates the forum rules, as I have no relationship with this company other then needing a cylinder service and considering using them...
I just got the phone, and Eric had great information and was very patient... I was debating between replating and staying stock, or going for the 225 big bore kit.
Looks like the 225 is a slam dunk. For $500, they will bore it out to 225cc's, replate with Nickasil, include the proper Wiesco piston kit, clean up the KIPS, resurface the head, inspect, measure, new top end gasket kit, etc. It basically comes back ready to bolt on.
It will run fine with the stock exhaust, and run even better if you switch to an FMF pipe. The job can be tuned for top, all around, or bottom.
After the job, it can be rebuilt / replated later if you do have to service it again. And his experience with the Nickisil finish (as opposed to the stock factory coating) is that you will probably never have to... and that you will get a lot more life out of pistons and rings. Also, the bigger bore keeps leftovers from the previous coatings from screwing things up.
This is all consistent with what I know about Buell motors... Nickisil is the way to go.
So if I understand the pricing right, its only 30% more to redo it as a 225 versus keeping it a 200, you end up with a better replate, you can keep the stock exhaust and stock reed setup, fuel economy isn't much worse, and reliability is as good if not better. And of course more power.
So it sounds like a pretty easy decision...
Anybody found a post 225 dyno plot? It'd be interesting to compare it to a modern 4 stroke.
