troubleshooting

I got an 80cc 2 stroke build here with a stock NT carb. finally got her going after many problems but here’s what I need help figuring out please: Bike runs good with throttle open only an 1/8th! I can only barley open it otherwise if I open anymore it looses power and boggs down hard! what...

Okay so been working at this shitty Niome 100cc kit for over a week can’t get it running think i’m onto something though finally. The bikes been bogging extremely hard and hasn’t gone faster than 5 kms and it doesn’t get uphills. Tried sealing gaskets with RTV to eliminate possible air leaks...

I’ve read almost everything I can and still don’t get what it could be. Basically I put the whole kit together on my cruiser and it wouldn’t spark so I checked the cdi and magneto for continuity, magneto read 318 so good there but CDI seemed weird it wasn’t showing anything then it was etc. Got...

So I bought a used basic Dimension Edge kit with the shift on the fly mechanism. I am mechanically inclined but just learning about bike motor kits. The kit originally came with the aluminum U bracket that attaches to the rear fork or seat post part of the frame. I changed the U bracket to...

Hi I have a 49cc huashengtaishan 4stroke up until the other day it was running good but all of a sudden while I was accelerating it just quit going. The motor never died and if I play with the trottle I could get it to act as if it was gonna take off. If I WOT it dies. I have drained the gas...

My 80cc engine from China (eBay) has not started since it was assembled a week or two ago. Fuel is getting to the engine, as the spark plug was wet when checked after cranking - for some reason it refuses to burst to life upon releasing the clutch. The engine will turn over after releasing the...

Okay this is my first post here, ive read hundreds of threads and finally decided to create an account. So here is the deal i had a perfectly running basically bone stock 66cc (nt carb 66jet, 2nd to top needle setting) and i had to ride 8 miles in the rain and it went south about a half mile...

When I pull the clutch my motor dies. I know this is vague but what are any possibilities. I can get my bike running smooth but pulling the clutch makes it idle for several seconds than it starts to slowly die, it is in the break in still.

Yikes. let me first start out by saying that i'm in a computer lab, and i think this is the wost keyboard I've ever used. It only registers about 7/10 key presses. I have just finished a cheapo china girl/wal-mart build, and after riding it around 15 miles yesterday (Class and back), I made...

I recently had my bicycle motorized. It has been working fine. I had a flat tire this morning. Had to get the tube replaced, so had to take the chain off the rear mount. Replaced the tube, put the chain back on to the mount. It was being a little sticky. Anyways, I tried to ride it again...

Hi, I have an oversized mount on the engine. The mounts are wide enough, but the curve does not match with the tube. Therefore it would have a large gap. I took and shaped the thick rubber from a grip I had. My question 1) will this fail, strength and vibration. 2) The original...
