What is the best race kart motor the hemi or non

Hi all, I realize this site is dedicated to mini bikes, but it is by far the best resource for modifying Predator engines. I'm a motorcycle mechanic and fabricator and will use a 212 Predator Hemi to build a longtail boat mud motor. It's nice to see how affordable these race parts are...

brand new take off hemi carb $15.00 shipped

Briggs animal springs fit perfectly in the hemi, they are a little shorter than 26lb springs. the exhaust will coil bind with anything more than 275-285 lift. They are a little more heavy duty than the 26lb springs with a touch more pressure. good for the guys looking for 8,000 - 9,000 rpm...

Here we go again and this ones gonna be fun . I have just finished a raptor build for my brother XJ ROCK , he has had this hemi on a rupp scramble for a year or so . He had a build thread and it came out nice . But he has seen what comes out of East Tn custom minibikes and bad ass everything...

Off a vertical lawnmower Kohler engine. One of those lonely nights on the road messing on ebay and found this. I think it will fit Hemi Predator. If you want to pay shipping and try it just PM me. I would be happy just knowing it worked and my hunch was right. :pimp: you will need Honda style fan

This will be my wife's rider , only way I could build one , lol ! Its gonna have a hemi , some chrome , suspension and be powder coated in magenta !

Yes another rupp project , this belongs to my brother XJ ROCK . He built this bike two years ago and really never rode her much . It started with a first gen predator that he unhooked the gov but didn't go inside and take out the little arm . Well it turned and locked the motor up . So off to HF...

Bone stock Hemi, Haven't cracked the case open as I'm leaving the governor installed for now. I am however switching valve springs for durability. I have a degree wheel installed for checking timing because I also swapped out the flywheel for a Kohler with a lighting coil. So I was turning the...

I'm fitting a lighting coil/ stator & stock flywheel from a Kohler CH270 to my Hemi Predator. I haven't seen where someone's actually bit this bullet, but I figured I'd give it a shot. Here's what I've learned so far. The taper does check good. I blued the crank & spun the new flywheel on the...

Hello everyone, As the winter approaches I am looking to take my Predator apart and make some changes. I am looking for recommendations on who to use to blueprint a Hemi cylinder head as well as purchase a blue printed carb. Any and all comments are welcome. Thanx in advance...

I put a new hemi 420cc predator item #60349 on my go kart a few months ago and now I'm looking to make some modifications to increase performance. Does anyone know if performance cams for a gx390 or the older predator 420cc will fit the new hemi 420?

I am after either clone or predator hemi heads to suit big blocks, so if anyone could tell me who can get me a few that would be appreciated. Cheers

Ill be building a friends predator 212 hemi, I'll be installing a real mikuni 22mm vm series carb. May consider a 24, will be removing the governer along with installing a billet flywheel, and along with the popular straight through exhaust. So far ive done some mild porting to the stock valve...

Anyone have any problems with the tank leaking at the seam? Just picked up the engine on Sat, new in a clean box. Was "throwing " together a knock around bike for my buddy to use as a pit bike at the track. Fired it up tonight, started on first pull, runs great. Smelling gas and see it seeping...

We race on a small track (1/10-1/12 mile banked) and I am looking to build a Hemi over the winter to play with next year. I have been doing some reading (will be my first build) and this is what I have come up with...what do you think: -port and polish head milled .030-.040 -Was thinking...

I have a gx160 head I want to put on a hemi predator. I also have a super box stock dyno cam. Can I use the stock flat top piston and rod with this cam?
