start

so I gave up on my old shift kit and bought a SBP shift kit. I got it installed and mostly running in one day. I'm having since chain problems I could use some help with. First I should say that I have a shimano rear derailleur and 6 gears with a 7 speed friction thumb shifter. First problem...

I have replaced every electrical component on my 66cc 2 stroke and still VERY weak/no spark. New coil, 2 new CDI, new magnet, new spark, everything. Any pro tips are appreciated.

How is it to cold start those 66cc 2 stroke engines in between -0 and -20 celsius (35F to -4F)? Do i need to have the bicycle inside at winter? Do cold start harm the piston and cylinder badly? Do the piston easily freeze and stuck? Is it hard to coldstart?

Here is my story... I have put my Chinese 66cc motorized bicycle kit on my mongoose mountain bike. Unfortunately, the regular chain that you use to pedal broke, and I have yet to replace it, so pedaling is not an option for me; but, I do have a pull start installed, which I have been pulling and...

I don't know if it starts or not yet, but I am having a lot of trouble with just getting the thing moving, the bike doesn't even budge unless I am holding the clutch, and when I am holding the clutch it is VERY hard to pedal where I can't even make it out of my driveway. If I walk the bike, its...

is there a way to turn the engine over without such violence. Every time i try to roll start my 66 in the parking lot it feels like i a beating on my frame with some hammers.

Ok so I have bought a Brand New 66/80cc bike motor off on ebay, installed correctly and everything but it is VERY HARD TO START meaning that every time I try to start it it pedals hard and Im thinking it might be something wrong with the cylindar or what. I am new to the whole bike/motor scene...

Picked up a bike and it has a shift kit on it. Some parts are missing though so I can't start up the engine. I noticed on the magneto there is a nut and if you turn it with a ratchet the piston moves. What if I hooked up a drill to it and tried to start the engine? Would it be ok and not destroy...

Hey guys, I have an 80cc motorized bicycle and I can't get it to idle for my own life. Also, it is very difficult to start. I live on top of a mountain and will go down the road with the clutch pulled in, then pop it, and the engine will begin to start, make some noises, I give it some gas, then...

Hello all! Was riding my bike the other day and it died slowly. After a bit of figuring I replaced the CDI ( used). It worked! Then about two weeks later and 150 kms of riding it died again very similar to how it did before. I did not notice going over bumps or anything when it died and the...

I can't believe this is $50 I have put into magnetos because of the pull start mechanism. I have replaced 3 times and now a 4th purchase will have to made. This is so annoying. And magnetos are Not the easiest thing to take out and replace. It has to be done, but damn it, I just want it to...

Hi all, I installed a kit in my girlfriend's bike, but the little $#%&$ won't fire, i ride it like 15 times arround the block trying to start it up (with the whole family on the street waiting to see it come alive) and nothing, not a single explosion. This is what i've checked: · I have...
