So a basic 420 should work at the correct length? This is only 7.5 hp directly driving the sprocket, no live Axle.41 works, 40 is better, 420 is best for common half inch pitch on karts and minibikes. I’m not too familiar with 415 and didn’t verify your sprockets.
ANY chain you buy is likely to be too long, that's why chain breakers exsist... or just use a punch since I know for a fact that the PT415MX is more than well designed enough to break most cheap breakers because they used a slightly longer rivet pin than most so they could make the mushroom bigger.If I'm reading that right, 120 links =60 inches, 5 feet? Seems kind of long, I have to count how many links I have, I'll do that when I get home from work.
I won't use those personally, I find them to be more hassle than they're worth, they're fine for a log splitter or other stationary equipment but its a matter of preference and experience I suppose.On another note I was in hazard freight yesterday and noticed this. Looks to be the same effect key/fuse panel as my ali Express motor. It was on a predator electric start.
Just making an observation, the whole panel is identical. I've already bought it and it works fine so I'm going to use it for now. If I have problems I'll replace it.I won't use those personally, I find them to be more hassle than they're worth, they're fine for a log splitter or other stationary equipment but its a matter of preference and experience I suppose.
I personally just wire up a keyswitch gotten from fleabay, advance auto, or the like. It starts my engine, gates my electrical just fine, and I use a separate toggle (because push buttons love to get stuck and prevent spark) for killing the coil since most of the common ones aren't dual polarity with a shut down terminal
420 would absolutely work, but if his sprockets are profiled for #415 the way he measured, a #41 will wander on the teeth a bit and a 420 will be even worse.420 should work. A 415 sprocket might be a bit thinner than a 420 sprocket. They are similar chains but the 420 has a beefier pin (with same roller diameter). And the 420 chain is 4/16” between plates and 415 is 3/16”.
So yes, 420 chain would work on 415 sprockets, but a 415 chain might not work on 420 sprockets.
No, you'd still need a fixed peg attached to the frame to keep the brake in place, however the peg doesn't need to exceed the width of the brake band itself in fact it can be a little shorter than the band is wide if you have a center pin to keep it in place.I think I can shorten the brake rod and convert it to a cable pull.
Yeah I intend to keep the peg, I made it shorter but may need to take another 1/8 inch off of it. I have some steel braided cable, copper tubing, and cable stops. I also have another rod, so I can take the original off and not have to modify it in case I decide to put it back to original. I will post pics of I modify it. I'm also considering making the slots for the motor bolts a tiny bit wider so I have a tad more room in that direction. I'm which case I can add a washer to the axel moving the sprocket away from the peg. So far we have had a few good rides up and down the driveway. He loves it although he is still kind of scared of it. One other issue I have to fix, the seat doesn't come with holes for the seat belt buckles. I'm going to have to cut and sew a hole for them to pass through.No, you'd still need a fixed peg attached to the frame to keep the brake in place, however the peg doesn't need to exceed the width of the brake band itself in fact it can be a little shorter than the band is wide if you have a center pin to keep it in place.
Otherwise converting to cable you'd need to add fixed cable stop above the band peg. Then drill a hole through the center of a bolt to feed the cable through, put a nut it and it becomes a tension adjuster and you just need a hole through one side into the center to thread for a set screw.
Why would you do that when you can pass it through where the back cusion meets the seat cushion? Far as I can see you have no cushions and that by itself is only slightly problematic.One other issue I have to fix, the seat doesn't come with holes for the seat belt buckles.

I bought a cushion from bmi carts that was mentioned earlier in this thread. It's a one piece cushion that hangs over the seat back and folds across the bottom. It fits perfect and is comfortable, but doesn't come with a hole for the buckles.Why would you do that when you can pass it through where the back cusion meets the seat cushion?
