Mr.RPM 912cc Big Bore kit up and running!

**Brian B** · #1 (**permalink**) 12-19-2009, 09:04 PM

This is the second 912cc kit ever! Greg has made 78rwhp on his quad on the dyno. I'm expecting between 75 and 78 to the wheels considering we have a bit more driveline loss than the quads do.

Mr.RPM for more info. This kit is $1550.00 and thats a smoking price for the amount of power they make! tell them RYR sent you!

Thanks to Kenny at KDS Racing for the 50mm throttle body!

Thanks to Muzzy's for the bolt on dual exhaust system for Rotax Rhinos!

Thanks to Rotax Your Rhino for the bad ass Rotax install kit and engine build! ( A little pat on my back for sure

)

Thanks to my homie Greg at LSR for all the time he's spent helping me work on this beast!

Dyno results soon!

Was the oil cooler warm? I sure as hell hope so.

Sounds sweet dude.

Thats awesome. What was the problem with the oil cooler issue. I know that they were not circulating.

Well, you told me you'd be racing it 6 months ago. Just wondering if you were?

One podium was all I will ever see I'm sure, 2nd in Page 2 years ago. I don't really like racing, I like going but not so much driving. Too fat, get worn out too fast. Too expensive ect......

That was funny...Brian I want to see that thing run and I purchased a small video camera to record it in Glamis..I know we will have a different finishing order this time...LOL

Gary, are you going to have your Rotax finished by Glamis?..I know you are capable of finishing it you just need to get in the shop and off the forum...lol

Yeah. When you use the right o-ring the adapter works great!

I didnt have instructions at the time of the install and didn't know the o-rings are different on the Wix filters I was using. Run an OEM o-ring on the adapter and it works great!

I dont think there is going to be any structure to New Years racing man. Just bring them, and run-em!

Not sure man. I got my stuff from Greg. Just call Parker Yamaha and tell the parts guys you need the chains, guides, and tensioner guides for an 09........

12:1 still! Compression is where the power is made. They run just fine on pump gas anyways!
