Need setup advice

Placement of that center piece, that's squared, is important. I like to put the pulley part with spring end at around 1 or 2 o'clock. Then turn the cam cc, then push down.

Try it a few times before installing snapring.

Got it!

Got it!

Awesome !!!!

How many times is it gonna take you to get it in the right hole??

Got it!

Look where pen is pointed. This is off my son's mini, his ducar 212 is way more then stock. It makes alot more power, he dont need the most resistant hole, he only weights 165#.

I 1st thought you was practicing, then I seen snap ring on.

That sucks. I was matching the picture and completely overlooked where you said that. I'm lining up the motor now. I had shaved the fins and I'm going to have to shave some more. The corner is catching.

Fabrication is part of it. You will get it right, tho. I'm sure.

The 2nd time is a little easier.

Good job!!!!

Take a chisel or punch or something and hammer, to make sure that snap ring is in there good. Theres a lot of pressure on that snapring when that belt starts shifting.

Why does the belt look so loose here???
What's the # on the belt???
What's the distance between shafts, center to center???
something don't look right, here.

I did. It's seated snug.

It's 203591. I thought it looked a little loose. Center to center is about 6-5/8". I can take the belt off tomorrow and measure better. I'm calling it a night. Gotta work in the morning.

At this point, the chain is turning freely but I'll adjust some more before I drill and mount it down.

I'll measure 1 tomorrow. But that belt looks too big.

@joshw0000
They the same, pics jus funny.
Don't over tighten the lock nut on the driven, too tight will pop the snap ring off the other side. Not much pressure side to side on the jackshaft. All the pressure is front to back

Sounds good, thanks. It does look pretty loose, both in the pics and in person. Worst case, I can try the smaller belt if it slips.

I'm hopeful that I get it mounted tonight and take her for a test spin. As much as I want to floor it and measure the marks, I'll have to take it slow for a little while. So there may be 2 initial launch videos.

Why did you mark the drive and driven bolts? Is that so you can check to see if they're moving after a ride?

What's up with the washers under 1 side of the block????
This puts the little sprocket in a different angle of the axle sprocket. May cause chain and sprocket wear.

These engine flex alot when mounted on, on/off throttle machines, under heavy loads. The blocks are strengthen more around the mounting holes. When you tighten down the mounting bolts, with the washers under 1 side, you created another stress point in a weaker part of the block. In the right situation, under a load, the block could crack, or break off at the mounting ears. Then it's trashed.

They like to be mounted to a flat, even, solid surface, with the most surface area, contact patch you can give em. Even being in a 15 degree angle is fine, as long as it has a flat, even surface.

Yeap. This is my son's. We where testing different gears, stall springs, driven spring locations, for his weight. It's a nasty lil boogy with his weight.

I mark areas and keep an eye on bolt movement.

I can wear a dam sharpie out!!!!!
It's the most used tool in my shop,

It was just for test alignment. It was late and I was tired last night. I overslept this morning, lol.

If I end up using anything like this the washer would be placed between the tubes and the steel mounting plate so the motor will sit flush with the tubes. It was just easier last night since I had short screws dropped in the holes to join the motor to the tubes.
