Why people chose Cruiser frames for their builds?

I welded all my 415 chains cause the link did not last 5 miles so I weld em all now. I ditched the 415h chains now trying out the 420 chain seems better so far. the 415 chains last about 1000 miles time for new.

GOT THAT RIGHT ABOUT A 212cc! I was....going into town this morning and got 3 miles out in the
country and let up on the throttle on a down hill grade (not steep) and heard a pop. I looked down at
the chain and it was missing laying in the road. I thought the keeper might have came off instead the
chain snapped while I started coasting. This Chinese 415 chain is no good and I am going back to the
41 from the BigR farm store, at least it's decent Japanese. The 49cc could stretch the Chinese 415
chain and I've never had it happen with the BigR chain. I am seriously thinking about pulling the
212cc and putting a 79cc on it. I'd like to put a shim on the 79's CVT crankshaft to shim it down
from 3/4" to 5/8",and again I might just go with the 79cc GasBike kit?
Don’t get the 41, that stuff is ****. Go to your local motorcycle apparel shop and get 420 chain. There is usually a $20 and a $30 420, the $20 one works great for 212. Don’t lube it. Don’t clean it either. Just run as is. I put about 20k miles on 212s. I seen everything.

It may fail there. Chains are made of hardened steel. Welding on it weakens it. Run the master link that comes with it and make sure the closed end is leading. Athough, I have done that on half links, and it was better than a cotter pin but after enough trouble I stopped using half links.

The 420 motorcycle chain is probably a good quality Japanese steel and the difference is apparent
by grinding on a link and trying to bend it. You can tell by watching the sparks featuring out on grinding
the metal. The 415 doesn't do that like the 41. I noticed the difference and when I tried to bend the outside
link arm away from the pin after grinding on the pin and I didn't have a chain breaker at the time. I need to
check into the 420 motorcycle chain and see how it works out. I was wondering if the 420 links seats good
in the sprockets? I'd never run full throttle on takeoff with the 212 the engine has too much torque for a bike
frame. The 212cc would make a great automatic transmission setup on a 125 Suzuki motorcycle!

I wish, I haven't even got 20 hours break-in on the 212cc yet and the 415 chain breaks! I noticed chain stretch on the 415
with the little 49cc mighty-mouse powered engine. The quality of the metal in the chain was apparent when compared to
the 41 chain which is industrial quality for farm equipment. I did find that the Micargi pedal chain versus the 7-speed chain
on the Sixthreezero was different and the Sixthreezero bike had a better quality pedal chain. I needed pedal power this
AM to get it back home just 3 miles. I've got a little over 125 miles on the 415 chain which is coming off!

I am not enthused about that darn 1" hub on the bike since there's not enough to clamp to with the hub adapter.
A set of mag rims might be the choice instead of the hub adapter. I never had movement on the 1.5" hub adapter
but it wasn't a torque machine like a 212cc.

I might have found the problem with that chain breakage. I noticed that on the 212cc kit that the CVT set screws on the CVT gear which has two of them were not matched to the proper lengths. The set screws were too long
and I suspect that they could mangle a chain link. The master link showed gouges in part of the link. The set
screws should always clear that 415 chain. I pulled the CVT apart and removed the set screws then I used a
drill bit that cleared the threads on the sprocket to drill a drill bit guide in the shaft so the gear could be removed.
I then used a larger bit to drill the shaft on a drill press just deep enough so the the set screws when tightened
would be flush with the top of the gear. The set screws are now counter sunk with plenty of clearance for the
chain links. I recommend to use the red (LockTite) on the set screws. Always check the kit for hardware to be
sure things are tight. I would watch out for this on "Death Row 212cc" kits.

My first completed build is a 26in hyper beach cruiser, in the end its not a bad bike runs well for a stocker, looks pretty good but like all things new it was quite a learning experience several lessons some preference. Other than my OCC's i wont build another fixie gear when disaster strikes and i have to pedal i want a low gear.I will not build another bike with a coaster brake i like go but there are those times for whoa.Even a little bit of suspension is better than none ( i use suspension seat posts on the choppers) and very importantly dont buy crap motors spend the extra 30 or 40 bucks and get a zeda or a runwell pk !
