Here is an example... My stock 30cc would only hit 24-27 mph with trenchers and flipped A&B gears then I put in a gp290 and blew the doors off the stock or the crmk 30 will leave the stock in the dust ..not all motors perform the same or are the same. I feel the stocker is over rated in terms of power from my experience and if you put one on a dyno I bet it hits about 2.9-3.1 HP

No worries Phill! Hell I confuse myself half the time lol. Gp290 is a CY and the G290rc is a zen and if I had to put a cost friendly and reliability with decent power it would be the G290rc
 
ok since the Zenoah 290rc has more power then the 30cc stock motor I will be ordering in couple weeks thanks everyone for helping me in my decision!! when I change motor do the gear bolts need to be torqed down if so whats the torq anything else need be torq down too?

have you ever tried the air filter comes with the g290rc or should it be changed thanks again for the help I would be lost if wasn't for you guys and I will be getting the g290rc
 
You can use the one on your existing engine... Take out the allen blolts that are inside the filter and swap over. Remember that the carb will come off when you remove the 2 bolts so don't panic lol.
 
I knew about switching the air filter was just wondering if anyone every tried running the one comes on motor
 
I have not tried the filter that comes with it...sorry I miss understood lol. It .at be good for street running.. I run sand a lot so I have to have superior protection with the Dt1 3 stage.
 
no problem maybe I should stick with the 2 stage v3mt one I run dirt and stones

I'm running my MT with the new 320rc and it was ported and polished by TRM power. The MT runs awesome with the 320rc
 
I don't own an MT but +1 or +1.5 bhp is not overkill on a drivetrain. G320 is around 4bhp, with a pipe ull have around 5.5 bhp. That's not extreme. I recall couple of guys here having Fullmods 7.7bhps on their MT. They can give you more insight.

Extreme means a reed motor or a bigbore engine. Usually 9bhp+
 
I have a gizmo's full mod and it's awesome the MT needs a strong motor so don't put off on a larger horse power motor because of issues ur gonna have issues regardless. ...lol....
