Given that power was never lacking on big bore 2 strokes, why the overachiever displacement?
Yamaha YZ465-490 con- rods fit the suzuki crank halves.
And then you have plenty of replacement options , pistons
Etc
Big Cat pistons, rods will also work. -(Artic Cat)
Southern flatlanders most likely have never been on a truly fast
200 hp 2 stroke sled!
Have you ever been to Hay Days?
Do the YZ con rods fit the RM400 crank? I had a 80' RM400 in high school and at some point want to pick up another one. I've read that finding pistons is difficult at best; wondering if your rod trick might be the solution.
The only sled I've been on was some rental POS in the early 80's. A 200hp model sounds like it would provide stupid levels of fun!
When I rebuilt mine last year I called my Suzuki dealer for another part and mentioned the lack of availability for a connecting rod. The parts guy looked it up in the computer and told me there was a rod in stock at a dealership in Idaho Falls. I called them up and it was in my mailbox two days later. Got the last one I guess. I used a Wossner Maico 490 piston in mine.
What was done to the top in to get to 540cc's?

The Shop
Luxon 4-Post Bar Mounts
$189.95 - $239.95
DeCal Works Huge Plastic Inventory of UFO and Polisport kits.
Rebuit, new fork bushings, Race tech gold valves
The forks work really well, just setting up different
Preload spacer lengths, I machined up spacers starting
From .5 inches in length up to 2.25 using YZ465 new springs.
Can swap out in minutes per track
Rear rebuilt with stock set- up spring, arms
Have been remachined using Al-Ni-Brnz
It works better than my new Honda, Yamaha I
Have for comparison
I just would like to find someone who has a
Contact with an Ohlins supplier.
The 465 engines I have a completly rebuilt
Top to bottom, new Suzuki rods, all internal
Bearings, even a new clutch basket In the one!
Mac suzuki had 2 rod kits on the shelf, I had
The clutch basket in a few days.
I have enough parts to build 2 more bikes.
The Yamaha rod has the same pin sizes, but
Is 5mm plus in length, c to c or more if i remeber.
Also the 1000 cc twin rods from a cat work.
It gets pretty involved from here. Rebore out the
Crank halves to accept a larger pin etc,,,,,
A guy from australia bought all my spare swap
Over parts for the conversion, I guess that was
2 years ago now
Something similiar
But you have to do the legwork
Look at the Wieseco main data base for
Bore and stroke info
For all mfg 2 strokes, buy up a few used
Engines and dissasemble and see what
You find?
Can get an YZ490 rod kit easily, but how much of that kit can I use?
Micah
But you might consider it will increase crankcase volume, maby its a benefit?
If you find a piston with 5mm lower compression hight(from pin to top of piston) you will keep volume the same as before
