Does anyone know if there are aftermarket cam kits or internal mods that will really wake this beast up? other than a $6000 turbo kit that is.
I'm thinking if someone could change the fuel delivery and change the camshafts would give an easy 30-40hp more.

I don't think it would be that easy,If it was I think Yamaha would of done it and made 175hp Nytro at 1049cc

Ok,So show me cams that will get me 175hp and I will buy them tonight!stopdropanroll said:
jeff you could checkout nw turbos they are out of montana. they have a plug and play turbo for 4500 with one of the best exhaust manifold set up available to snowmobiliers. no need to spend 8000 on a turbo. mt dream has one on his nytro and is a tester for NW. easy straightforward, no nonsense turbo yields over 200 hp. just a thought. ski

He obviously never said that just cams would do it. Simply stated that Yamaha would not do it and I happen to agree!

Why wouldn't they? They would be making the same HP as a 1000cc two stroke with the same CC. Why not do it?no4smoke said:

Just remember that on the Doo 1200 you have to replace the primary clutch with something that wont blow into a million pieces. MCX uses a Comet primary.Daranello said:skidooboy said:

That's not bad but i was still looking at camshafts and getting the cost under $3000 (which shouldnt be hard to do if you just change the fuel setup and camshafts). Would also be pretty cool to have a sled that "loped"skidooboy said:
Now that would be bad #*$&@ as well

Personally i would say that 175 hp from this motor would be quite easy for yamaha but then they would probally come up against reliability issues and long term maintenance.

If you want to squeeze 160-170 naturally aspirated hp out of this engine you will need a considerable increase in operating rpm.jeffT said:
Not a good idea considering clutch efficency and the 1:1 ratio between engine and clutch rpm...
There's a stroker kit out there from Hauck that gets you in the 170 range. Fundy performance is doing porting and cams in the 165 range.

what's the cost? where is it at on their website? To be honest, im not totally sold on hauck's stuff. I think there are better products out there but,......... im not a professional and that is only my opinion.Rx1M5 said:
