chain alignment

Hey Everyone, This is my first post on the forum. I'm working on my first build and finally finished it up but realized my chain alignment was really bad and creating this "popping" noise. The only way I can see to bring the drive sprocket and rear sprocket into alignment is to thin the outer...

Hi folks, New to here so thought I would say hello. I got myself a pretty awful $90 chinese morotized bike from banggood and I'm trying to fit it to a 18in Kona Hanana frame.I'd appreciate some advice - although I've managed to overcome some problems, I'm struggling with the chain rubbing on...

I'm working on my first build at the moment, just surpassing the stage of mounting everything. After mounting the tensioner, I rode the bike around to see how fluid the whole chain assembly was. Everything is working fine, except for the tensioner which is slightly diagonal in relation to the...

I have the Aurelio Tech 80cc 2-stroke motor kit for my mountain bike. Everything has been just fine except for the chain. Originally I had the tensioner way too tight and of course the chain snapped. Luckily it just broke the master link. So I ordered a Chain Link Remover and fixed it...

So i got myself a new hyper bicycle with a new 66/80cc motor. After awhile of riding I felt that my chain had fully stretched so i tried to tighten it up again. While tightening I found that the slack of the chain would change to loose and then tight when I would spin the wheel so I figured...

I thought maybe mounting the rear sprocket on the disc mount would be a better mounting than either the rag joint or the hub adapters. I got a 38T and 40T since I wanted just a little more top speed from my 49cc 2stroke. I probably should just gotten a hub adapter for my old rims. this sprocket...

I am using a kit that sat around in storage for a while. the engine turns over so i left it in intact but i took apart carb and cleaned it. any common problems with engines that have sat that i should be aware of? mine is missing a spark plug. can anybody recommend a replacement? (there...

Newbie here! Just finished my first build - thing is pretty sweet. Strapped an old China Lady to my cruiser and the thing flies. Only a couple things I wanted some advice on. It bucks pretty significantly at very low speeds. I know at low revs engines tend to do that, but this seems a...

Hi I am a newbie and I started building the bike over the summer and gave up! But, a month ago, I started again and finished and got it working. After about one tank, and a few little kinks, the chain started to fall off every time I would ride it! I replaced the chain with a heavy duty #41...

my engine keeps tilting to the left side of the frame and it already cause my front 10t sprocket to break 2 teeth, anyone have some advice? im running a custom mount up front cause my frame is thick and im using a steel plank and 2 U bolts, there on really tight and when i ride for a bit the...
