Drewpy, I have a spare motor sitting here I'd sell for much much less than that. If you want to price out shipping from Canada (my postal code is K0K 2Y0) we could work something out?
See what your nice rebuilt motor is worth, and price up the shipping and cost of this offer from hutchinson, do the maths and see if you can come out on top
did you use the 72mm?
Going back to the 180 vs 360 crank and plenum issue.
On another Victory Library page he does mention larger plenums for two cylinder 180 degree crank engines. Almost double the plenum size on the 180 vs the 360 cranks.
Might be easier to make the plenum larger than to rephase the crank and get custom cams. The AMR300 is already oversized for the application so filling a larger plenum won't be an issue.

Second-to-last table, "Plenum volume vs. engine type".
no, no date, Just had the bike MOT's and just put together the FZ so i'll start using that.Drewpy, I want this to succeed so bad I'm going to be jealous when it's done. Any idea when you plan on having it complete?
might have to do that anywayHave you thought about removing some of the squish area from the head? Might be better for a boosted application. Wouldn't need to take much off, just enlarge the chamber a little.
Fair enough. I've tracked down a few people who've documented tearing them apart and it doesn't look fun. If you ever do though... even that center-to-center shaft-shaft distance would be helpful.not going to disassemble the AMR's they are tricky to get back together and need a special tool to keep the rotors aligned on assembly.
Well this getting quite technical, well beyond my current skill set lol. Very interesting to watch this unfold, should be an awesome upgrade when done. How much are you budgeting for this drewpy?

That Aliexpress piston is intriguing. The shorter height from wrist pin to crown should get your compression ratio down as much as you need without modifying anything else. Good find.
BTW There's an Aliexpress sale coming up on the 29th. Using their smartphone app can give surprisingly better deals sometimes.
