Hey guys I know its been a while,

My question was: How much weight will a predator 212 push if the gear ratio is 12:45 (I know someone is going to correct me on whatever mistake i made there). If you need to know, I want to be able to go at least 23 MPH. (u guys are going to say something like, "isn't that a bit fast son?') Well I hope I provided enough info!

Thnx,
A little kid

I assume you mean 12 teeth on clutch and 45 teeth on driven sprocket?
That would make your ratio 3.75:1.
Way too high to push anything. Clutch will be severely overloaded.
Typically, ratio should be 5 or 6:1 with ~11" diameter tires.

So let's say I had the 6:1 ratio and 11 inch tires, how much weight would I be able to Push with the 212 and how fast

...how much weight would I be able to Push...

How much weight do you want to push?

I am going to sound really inexperienced (which I am) but, around 350 pounds total including the driver, give or take a few.

I dont know how much the 212 will pull but i weigh 225 lbs and
Have use them on several karts, alot will depend on what type riding your going to be doing. JMO

I will be riding on mostly asphalt and gravel if it helps to know. BTW thanks for all the responses so far

No problem.

An 11" diameter tire with 12 tooth clutch and 72 tooth driven sprocket will yield 19.6 mph.
This assumes a governed engine.
Less teeth on the driven sprocket will increase speed.

If you have about a 6:1 with 11" tyres, you will easily push the weight you are talking about. Easy!

With a 3.75:1 ratio.....you have no hope

Thanks everyone, that was really fast. I got all my answers in less than a day! this forum rocks!

My brother in law is 288 lbs riding a old heavy Rebel cart with a 6.5 Honda (basically same as the 212 Predator motor) with basic mods (filter,jet,header pipe) and he is running a 12/60 T count and the 11" tires. He doesn't beat any one out of the hole but he doesn't have to push start and he isn't smoking the clutch so he is pretty happy with it. I guess my point is you won't have any trouble using the 12/72 OR 12/60 on yours as well. Anything lower than a 60T count sprocket and your just going to ruin clutches every 5 minutes.
