We investigate a customers bike because the kickstart is seized. First we check and set the timing.

Good information video mate :). I Can’t help but wonder why you tried to kick start the bike even though it wouldn’t do a full crank revolution by hand ?.
@motorcyclefixer3 жыл бұрын
Sometimes when you turn it by hand you can't get it past the compression. I didn't kick it, I just wanted to rotate it with the kickstart.

I've got a 155z m2r 160cc engine in my pitbike, giving off a rattle, sounds like timing chain to me, still runs sweet, but I don't like the rattle, so with this video, il be having a go at replacing my timing chain.. Wish me luck lol

I have a yx 140 simi and gears won't down lower than 3rd but will go in 3 an 4th . Tire is stuck, kick start is stuck so I can't start it. What can the the problem. The. Piston dose move and the fly wheel moves so it's not froze up . I'm lost . Cant find any rebuilds on simi only manual
@motorcyclefixer3 жыл бұрын
It could be the gear change mechanism or it could be the gear change drum or one of the gears maybe stuck on a shaft inside the gearbox. Watch my other video on stuck gear change and try that first. If it's not that it's internal I'm afraid

Hi, just stripped top end on a stomp 140 can anyone help take the valve rocker arm out? There was two little looks like spring washers on one side of the arms. Can anyone tell me how they go back please Thanks
@motorcyclefixer10 ай бұрын
to take out the rocker arms you need to pull out the shaft from the head using a bolt into the end of the shaft. The threaded end of the shaft is the opposite side to the cam chain. you usually have to remove the block where the oil lines go to the head

It could be any one of a hundred different things. You'll need to isolate the problem. Start taking the casings off and checking everything. Sorry it's not very helpful but it's hard to diagnose a problem without seeing it

Could be your valves tapping if the timing is off. If its half a tooth then your chain might be stretched.
