[minibikekraze]

okay so i have a mongomery ward frame well the motor was was montgomery ward but anyways i went to the swap meet and i found this huge motor so i decided to buy it for 5 bucks well the thing is it fits in the frame but the the thing that the clutch will be at is a little taller than were the sprocket is so what should i do

That should work. Might have to mount the clutch inboard to get the chain to line up.

Most all engines set up like that. The crank is higher than the rear sprockt.

 

[incogrhino]

So... your saying the cranks to long? The clutch slides around?

 

[minibikekraze]

ya its higher so what should i do i dont know what inboard is

you can use a jack shaft mount like one of these to put a jack shaft on your bike. That way you can move the gear on the jack shaft out far enough to line up with the clutch gear.
If you are not sure how to set it up someone might have a picture of one to help you.
That big motor will be a power house on a small frame like that but it will be fun to ride if you can keep the front wheel on the ground.

Flip the clutch around :shrug:. Chain towards motor. Try that...

Thats what i have to do to mine. Just make sure the clutch you get is a bi-directional .

The crank shaft is a little to big for my clut h how do u measure it

 

[buckeye]

Measure across it. That will give you the diameter.

 

[mmisterbungl]

this is how you find the DIAMETER of anything that is the shape of a circle...

That's 6-3/4"

I just put a HF 212 on my trailcat. It's gotta come off,like they say,can't keep the front wheel
on the ground. All HF sells is 97cc or. 212cc. Now what? That 97 has a different size base.

So you gear it up, don't ditch a perfectly good motor.

Its all gearing. My 3.5 horse Briggs pushed me at 32mph on my lil Indian. Jackshaft.

Put a helmet on and tame that beast!!!! Kind of like taming a horse. Don't jump on the throttle, roll into it easy! Or build a wheelie bar and have a ball!

Or you could just put some taller gearing on it.

What happens if you actually put the engine on the motor mount part of the frame??

I was wondering the same thing,looks like your trying to keep the recoil out of the way. The motor might fit in the frame but it doesnt "fit the frame"
If you use the mount holes you should be lined up.
