Where do you guys find 1000cc 2 Cyl Motors at? i've seen a few pictures of them but just never been able to find any source of them

Application?

If you're talking about basing it on a Yamaha 701 bottom end:

Designed to 1L: www.adaracing.com (989cc, bigger with bigger stroke)

Some builders get close to that with Lamey cylinders.

Lately a few have done it starting with the Yamaha GP800 motors since the stock stroke of a GP800 motor is the same as what would require a 10mm stroker on a 701-based motor.

What about for the SX-R?

i dont think anyone make a cly for that.....
ive been looing for a 750 project.

the stroked crank is almost $800,

i think you can stroke and big bore an 800 to a close 900

See i havent even found any stroker kits for the 800

Crankworks makes stroker Kawasaki cranks.

The old PJS / WPP stuff ran a wider bolt spacing on deck so bigger diameters could be run. 86 to maybe even 90mm.

just shoe horn a 701 based yamaha in the kawi you know it would be better

I think some racers are putting Sea Doo 951 motors in SXRs. Might do a search here or that other site for more specifics.

PV cylinders are being made in Japan at the moment, not sure on bore.
They will use Yamaha exhausts as they have bigger diameter manifolds.

Thats what im talking about. some day i would like to build my own motor but i have a lot to learn about 2 stroke porting. I understand most of the theories of operation about a 2 stroke motor but there is a lot i don't. any one have any good resources

i know the biggest you can go on a stock 800 cylinder and cases i believe is 927 with a stroker crank and big bore 66V cylinders

in cases of 1000cc monsters you are talking stock but highly modified cases and custom one off cylinders such as what you see in the case of the DASA, ADA, Lamey, cylinders

 

[Matt_E]

We're talking Kawi cylinders, Dan. :fingersx:

 

[the only couch rider]

it seems then all you would need is

and a stroker crank along with the TBM twin pipes
