You would have to switch the engine out with a single speed engine.
80 cc hetrick shifter motor for 80 or 90 cc single speed any takers thanks
Frank,
If you make the shifter an auto shifter it should be legal to run CRA, at least that is what they told me when I ran my sons cobra. If I made it like the hondas and not a manual shift it would be legal. Is the shifter for Ries??
We ran the big bore single speed in 90 prod in 2007. It ran ok and was fast but the way our class was set up we ran with auto clutch shifters and were outrun on the top end but for supercross the 75 cc motor rocks.
I believe that the biggest that you can run and have it last is a 75 cc. ( the clutches and slipper will slip if you go any bigger )
Some have tried a stroker to 82 cc but i was told that they got too hot due to the design of the cases, it could not be corrected thus reliability is a big factor.
Hope this helps.

yes for ries just to finish cra seson and then if he likes the quad i will et red of the corba motor and put a crf 150r motor on it for supermini
i have not gotten very good response when i contact CRA to get a rule clarification on our Cobras.
I am told that we can run our shifter with auot clutch in 90 sr as the Hondas do.
Is this true???

I'd get it in writing!
Also, If you don't care about points then you can run your shifter. As of right now the classes are "cvt". If more auto or shifters show up I'm sure they would make another class. There just ain't enough of them show up to make a shifter type class.
The ppl running for points are the only ones that care.
Alec Miller has run in CRA on his Cobra and they awarded him the 1st place trophy but not the points. Just do yourself a favor and make a call to whomever and make sure they will allow it.
CRA is very quad friendly.
Hey Frank, You need to speak to Troy Symborski about his 80ish auto engine. Once it was dialed in, No-one could touch it. He even has a stronger engine sitting on the shelf!
I believe Wiley had something to do with these engines.

Troy sold his quad and motor at Lorettas.
I do have 2 80cc ported wiley motors that are fresh and ready.
( 1 in the box never even heat cycled) ( rebuilt for lorettas as a spare .
These are dependable and fast.
We all run about the same setup with our Cobra motors.
Paul also built 3 Cobra 90 motors with RM 85 TOP ends that are pretty fast. ( horton, szymborski, gennusa)
