Hi mate I just changed my head and not when I first rev there’s a mad slapping sound coming from head and a puff of smoke , any ideas what’s causing , it’s iirtating me
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
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
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 ?.
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
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
Hi I'm sorry i can't remember the size and i don't have the flywheel to measure it any more If you measure the hole in the flywheel and add 2mm on for the depth of the threads that will give you the size you need Best regards M
You sound welsh do you have a shop or anything because I have a stomp 160 with a jammed gearbox and I need someone to have a look at it and there’s no one in South Wales that can do it for me
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
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
@@motorcyclefixer Yh OK sound, I will check it It's just a jingly rattle, doing my head in, as its on the road, do don't want it letting me down on the lanes in middle nowhere.. I'd rather spend the money n have it right.. Thanks mate.. Good video.. 👌💪👍
@@motorcyclefixer hey man where is the timing chain adjuster please answer asap thanks I hit the sub button😀and it does not have the tensioner in the middle btw it is a 110
@@Eli-tg5xz on the 110 the tensioner will be spring loaded from the bottom of the engine There should be 2 bolts on the bottom, the one on the left has a pushrod and a spring above it that pushes on a lever behind the stator plate
@@motorcyclefixer yeah the boy was riding it for a couple of days and not starting now. I got it here down the shed, the kick start is kicking back like mad
@@connorjack3246 I wouldn't have thought so Could be timing, carb, coil, speak plug or a mixture of them all. Need to iron them out one by one. More likely to be the carb though if it's brand new
@@motorcyclefixer the engine is still in the bike sorry mate. And how much would it cost to put new piston kit in if I supplied the kit please buddy. could you email me please Jamie123wales@gmail.com

Yet another great video. Keep up the good work.

Did stevie wonder rebuild this engine
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 ?.
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.

This happened to my bike but the cam bolts stripped off
2:50 I need to buy the flywheel puller but im unsure what size it is. I have 24mm and 27mm to choose from
Hi
I'm sorry i can't remember the size and i don't have the flywheel to measure it any more
If you measure the hole in the flywheel and add 2mm on for the depth of the threads that will give you the size you need
Best regards

@@motorcyclefixer it’s alright I gave OORacing a message and it’s 27mm if anyone else ever asks
Buy a kit
You sound welsh do you have a shop or anything because I have a stomp 160 with a jammed gearbox and I need someone to have a look at it and there’s no one in South Wales that can do it for me
Hi
Yes the shop is in tredegar
It's m & l motorcycles
Greats from Amsterdam 👏👏
Thank you
Please reply , On my m2r yx160cc engine , is sounds like a little ball bearing is rolling around in the engine when idleing what could this be
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.
Maybe it's a little ball bearing rolling around in there?
Bro these things are notorious for kicking back and cracking the case
Subbed!
Thank you 👍🏼
How do you know the cam wasn't 180 out when you put the 2 bolts back in???
Make sure that when you bolt it on, the cam lobes are facing away from the valves.
And not compressing them
Because the valve springs hold the valves in the closed position?
@@magicdashcams506 yes
@@motorcyclefixer Guess I didn't think that all the way through...........I actually knew that Duh
My timing is off by about half a tooth which is as close as i can get it. If i move it anymore its at least a tooth out. Will this be ok
Yes normally it's ok
Just make sure you've got the chain tensioned when you check it.
If it causes problems I would change the cam chain
@@motorcyclefixer perfect cheers mate, should be ready for a run now then 👍
Chain tensioner needs adjusting or replacing, this will give you your half tooth back
Yes

Check the chain tensioner first. If it's that you won't have to strip it down
@@motorcyclefixer
Yh OK sound, I will check it

Bhai mere bike me timing chain tooth gaye hai to app yeh batao ki timing chain tooth Jane par kick free ho jate hai
I'm sorry I don't understand
Hi, where are you based? I'd like you to have a look at my bike if your not to far?
HI
I'm in tredegar, south wales.
mine sometimes gets stuck like that. Then moves and feels like its going through butter.... Then works fine
Perfect
Thank you
Hi mate I got a brand new M2R hear it wont start it keeps kicking back any idea what the issue is please thank you
Has it ever been started since it was built
@@motorcyclefixer yeah the boy was riding it for a couple of days and not starting now. I got it here down the shed, the kick start is kicking back like mad
@@motorcyclefixer I been trying to find the pitbike spec sheet where you had all the tolerances for the engine and for the flywheel
@@motorcyclefixer fires up and cuts out got fuel and a spark maybe something to do with the flywheel tolerance and magneto maybe
@@connorjack3246 I wouldn't have thought so
Could be timing, carb, coil, speak plug or a mixture of them all.
Need to iron them out one by one.
More likely to be the carb though if it's brand new
Did you manage to fix this in the end mate
hi
Yes i found there was a dropped / bent valve on it
there is another video where i strip the head off and show it
Hi mate, I got a yx 160 that needs bottom end rebuild how much do you charge I got all the parts
Is the bottom end already taken apart
The bottom is is complete at the moment but it’s out of the bike and ready to be cracked open
@@chrissmith3882 good that's best
What's wrong with it
@@motorcyclefixer do you have a Facebook page I can message you on mate?

Hi mate are you still fixing pit bikes and where are you based please
Kind regards
I am but it depends what you need doing really
I'm in Tredegar
@@motorcyclefixer oil rings need changing that's all I'm in tylorstown near maerdy. Thanks alot for getting back mate 👍
@@jamiewilliams8940 you'd want to put a new piston kit in it.
If you can bring it to me I can do it.
Preferably just the engine

Jamie123wales@gmail.com
i did the same thing 20times and the piston still tuches the valve after the rebuild
Are the valves adjusted properly
@@motorcyclefixer not sure, the cover is stuck on it but imma try to chek
@@sqxish.9325 On this one I did the valve was bent and not closing
The video after this one shows me taking the head off and the valve wasn't closed
@@motorcyclefixer the valves are working fine its just its tuching with the piston sometimes and it doesnt wanna start
@@sqxish.9325 It could the valve clearances then

Why the gloves
Used engine oil is carcinogenic so limit your exposure
Isn't everything? I've heard rubbing alcohol is too.
@@ratdad48 best to wear gloves then if you're using it a lot
Helpful tips to help set my timing.
@@ratdad48 I'm glad you find it helpful
ist not chinese
Yes it is
@@motorcyclefixer no it’s not
