Did you have to gear it down any?
Are you using a Rekluse?? I've heard they rule on a 500
13T on the front sprocket. Yes, has a Rekluse. Be sure and tell Rekluse your installing on a snow bike so you get some tungsten balls for better lockup of the clutch.

That would be sick but the price tag isn't going to attract to many buyers, by the time you do all the add-on's that are required to optimize the power output your looking at $4500 which is what I paid for my 09 KTM 300. Hard to justify that kind of money but I am sure there are a couple people out there with pockets that deep.
I would like to see somebody build a kit with a belt driven m1000 motor. I have my M1k putting out about 200hp with just bolt on's, I can't imagine having that kind of hp on a mh kit.
Brad,
The 585 looks great. Looks like a CPI cylinder? I have a CR625 in build right now at RPM with CPI cylinder + stroked (Crank Works). Checkout http://rpmmfg.com/CR625BigBoreStroker.aspx
I wish I would have found you guys sooner, its taking forever to get it finished....

I have seen his stuff. I don't know why you need to stoke a motor to 84.5 mm imo the 79 stroke is perfect. All my big motors have proven themselves at that . I will be curious to see how or what he is doing for your head. The head cpi uses will not work in your bike as it has a straight plug. Also I have a billet carb manifold for the offset . What are you doing for that offset on your carb . Maybe there is a better alternative on this that I haven't found yet.
Brad
All good points and I'll have to ask RPM about the head and carb offset. While I'm hopeful (delusional?) about the RPM 625, if I had it all over to do again I would not use RPM...

I would still love to help you if you need some help just let me know . I can hook you up if you like with the neccisary parts for your install if you need. Let me know how it turns out anyways . Thanks

is that real Dave? did allan put that together?
It's photoshopped and not to good either. But I think the point was to just give an example of how it should look and make us all think/dream about the power and sound when riding it.
Right Allen?//Rob
It is photoshopped. Dave did it for fun. But we are making an R-1 Super Snow Bike and will look a lot like this picture all except our bike is blue and will have a 136 track or longer, not sure yet. Hope to have it on the snow by the first of the year. If it works well and can get all the bugs worked out I will ride it up the hill at Jackson Hole.

i rode the 750 gsxr bike around the yard last weekend, wow it is going to be fast. mine is ready for testing on the snow. the next one i do will be with the frame that the motor came in.
136 is it going to be hill climber only?
136 inch track
No, the 136 inch track will be an all around boondocking setup for higher HP bikes.

Turbo CRF450R Build
A few pics attached of the compressor side of things. Next, Kelly at KMS will be fabricating the plenum and the exhaust side in the next few days. Hopefully turbo'd dyno runs by the weekend.
Interesting note. Baseline dyno on the brand new stock 2009 CRF450R was a pitiful 43.93 HP. That would be a whopping 30 HP at 10,000 ASL. Stock dyno run is attached too.
More to come...

Thanks.
We're building 2 bikes.
This one is the stock 450 turbo'd and were looking for around 75 HP on the dyno.
The second bike, another new 2009 CRF450R, we have removed the engine and KMS is building a "gorilla" 550 to turbo to around 110-120 HP... I'll post pics of that when the motor is back together and back into the bike.
Turbo/wastegates/Fueling will be setup to adjust for altitude to maintain near dyno HP up to 10-12,000 ASL.
KMS Performance is doing all the work. Kelly at KMS is big into custom ATV and UTV turbo builds for the desert rats in Arizona climbing those big sand dunes. He's already turbo'd several ATV's to the numbers we're shooting for. Biggest challenge is getting it all to fit on the bike... I can hardly wait for Kelly to fab the 2 1/2" exhaust.
