that motor could be easily tuned using our V990 parts and methods :cheers:
do the ATV guys knows about us?!!?

[Gabro]

some can-am aftermarket could be used on our bikes too:

You'll find a better match with the CanAm Spyder engine. It's basically a Falco engine with a 5 speed and reverse tranny.

there's some serious stuff too:

I have taken numerous calls from ATV racer's looking for go fast information and parts, the last one wanted 33mm exhaust valves. They all claim to be making 60-70 bhp, which we all know is false but, apparently a lot of parts interchange!

[Gabro]

i've one ported front head, sigle plug, to sell :cheers: maybe those ATV guys will buy it!
(and maybe I can sell the manymany 10.60mm lift camshaft from '00 RSV and Falco that i will never re-use and now are taking rust and dust on my shelf :worship: )

i'm intrested to those titanium valve springs and retainers :p:

ROTAX V990 WILL NEVER DIEEEE!!

450 motor with half a 1060 kit and 57TB in a RS250/125 or RS4 chassis? or even in the ATV

[Micah / AF1 Racing]

Now that is an interesting idea, easy enough to do too...hmmm....

[Gabro]

someone already did a supermono bike using the 499 motor :worship: :

Piston is not compatible. Need a longer conrod to be used in the V990.
And cams have lower lift and less duration.

With high-comp piston, V990 cams and 57mm butterfly, the 449 could be really powerfull.
Rotax sub-contracted developement for pneumatic valves for production ATV. It was based on late heads (with oval exhaust exit). I saw a head on the test bench, very nice building. Rotax build a series of 1000 or 2000 heads. But the project was stopped when the sub-contractor stopped its activities due to financial crisis. A mate who was working on this project said the motor was very powerfull, about 70hp. He was planning to use this stuff on his own V990.But as everyone was fired, his project also stopped. I don't know what Rotax made with all this project.

What a shame that he totalled that beautiful bike. It's like someone died when that happens. You're just heartbroken.
