DO NOT USE a ball hone on a plated cylinder, or you will ruin the plating, use a scotch-brite pad and some lubricant like wd40 will work fine,. you're only supposed to use a hone on a steel sleeved cylinder like on banshees and alot of older bikes have steel sleeved cylinders. the way to check is get a small magnet, if it sticks to the cylinder wall then you have a steel sleeve, if it doesn't then you have a plated cylinder.
I had to send my cylinder out. I called alot of machine shops and motor sports stores stores in my area. No one could touch it or they wanted over $500 for the cylinder and a top end kit. I guess you need a diamond tip bore becouse it's nickel plated (1999 yz125).
Also make sure you use a torque wrench when you tighten down the cylinder nuts, if you don't one side can be ue-even by a bit, and tighten to whatever torque spec the service manual says, or you can probably find a free service manual online..most yz125's have the same torque specs.
Only way to learn is research and then jumping into it. I remember being 10 years old working on my old Yamaha 60 JT1. And you get a thumbs up just because of your hair. If anyone doesn't get his gentleman a thumbs up/like on his hair alone you are a hater. Good video. W.F.O.
Do half assed work for a half assed bike. $40 is cheap considering you don’t have to buy the tool and you’ll know it’ll be right. Join a forum and do a lot of reading. Or watch videos on how to fix it. It’s not like you don’t have the resources or people to help you out
Given the care you took during the rebuild who would've guessed that it it wouldn't start. I'm not sure which part of the vid was my favorite - the the parking lot hone or your knowledge of spark plugs. Did anyone else notice the popularity of. the #69? I enjoyed this so much I had to watch it twice.
Wow. Look at all that dirt waiting to fall down into your motor. Always pressure wash first. Anytime you blow one up split the cases. You got metal shavings in the lower end. Won't last long. Live and learn brother. You don't need a hone. You need cylinder replated.
+RustySkull Productions taking the bike to the shop rn you’ll see the updated tomorrow I have to keep my gas off or the whole tank would drain out the overflows of the carb that’s the problem at the moment
Tucker Racing I was being supportive. I think you should calm down a bit before you blow a gasket dude. I was just saying it isn’t always a must to re-hone a bore. And I wished him good luck with his float issues. That’s all it will be with the over flowing petrol. A stuck float. By his comment back he took my comment how I meant it, with good intent.
Highgear MX You’ll get it going soon then Dude, it’ll just be the float stuck it should take the shop long to fix that :) it was a common issue with older bikes :)
the number just indicates how hot the plug is the higher the number the hotter the plug yeah a 8 is good its in the middle so u wont foul or bun a hole through your piston
Im not trying to sound like a jerk off. Im just trying to help you out like everyone did for me when i started wrenching. First off. You used the wrong hone. Ur supposed to use a ball hone. The one you used is meant to take material off. Not cross hatch. Depending how long u ran it in their for and how wore the cylinder is u couldve done some damage. Second for the gas shooting out the top of the piston. It sounds like u torqued the head to one side when u torqued it if at all. Do not ride it the way it is. U will heat it up causing the head to warp. Some with the cylinder depending how bad. U have to torque the head in a star pattern like a car. Skipping over every other nut the first time and repeating that process for the second set. The torque spec on the head is 25ft ibs i do a little over and like to creep up to it. For the cylinder. Tighten each one snug. And across to make sure they are even then with a box end torque to about 30ft ibs. Usually reasonably tight with some power behind it. Not like reffing on it but enough where to get it any tighter you would. Also replace all gaskets an o rings now. U compressed them so they wont go back to form and may blow out now that their torqued funny. I wish you would reach out to me. I could assist you and talk u throw it and answer any questions u would have. I could also get u parts really cheap and can find any parts u need. Good luck
85 weight oil is a little thick for your crankcase. May work but in my opinion I'd use a lighter oil. and I hope you don't use that for pre mix. yamalube r is my favorite.
You cannot hold it out or board out I have the same bike and it blew up on me you have to get the cylinder shipped out and re-chromed because it’s a different metal sorry bro or buy a new cylinder
The numbers on the plug is the heat range. Its not how hot the plug fires its how much heat the plug retains at operating temps. Also the lower the number the hotter it is. A br8es is hotter than a br9es plug..
Roostmx - you've got it reversed, on an NGK the 8 will be hotter than the 9 (don't sweat it, we can all be al title dyslexic some days). The 8 or 9 can be run in YZ125 depending on a several factors such as jetting settings, premix ratio, outdoor temp/humidity. One place that really tied it all together (for me to understand) was the carb and jetting section on the Kawasaki KDX forum (and they directly discuss different plug options). Good luck with the rebuild.
Alex Dixon my brother has a 1999 yz 125 that we put a brand new Wiseco piston and it almost 200 hours ago he's been riding it for 2 years straight at 44 to 1 gas mix ratio and we did one heat cycle and then rode the bike balls to the walls all the time and it has yet to blow up
They will need the jug, piston and rings at the shop to hone your cylinder properly. Yes it has to be done. Don't use a scotch pad or what ever ppl are telling you. It took 2 weeks to get my cylinder honed at a local shop. They won't do it quick because it's such a low paying job and they have higher paying clients ahead of you. When you reassemble you need to check the ring end gap as well or it will never be right. Also reassemble with 2 stroke oil on everything. Oh man you have to hone WITH oil. You honed it dry and it probably messed it up pretty bad. Also I think you need to use a ball hone, not the one you used.
Ur not supposed to hone nikasil... if u do it takes off the nikasil coating which makes the friction levels between the ring and cylinder increase causing excessive ring wear and ur bikes top end will not last as long
hey sorry to say something but you will have to hone it and the piston ring would haven't full off the piston and the ring willnt go down the bottom end I have done all the work on my bikes and snowmobile
Do not run a br8 unless your fauling tons of plugs and getting oil out your exaust they make your bike run hotter and if it’s not splitting oil and fouling plugs your gonna blow it up quickef
+breezeffs jump cause the bike is flooded with gas I took spark Plug out to pump all the gas out .. the carb just pours it into the engine for some reason
check your float level. take apart the carb and clean it good. and see if the problem is still there. otherwise you have to reset the float level.when my buddies kx125 flooded like that there got some gas into the pipe so also check that there is no gas in the pipe!
me and everyone I've ever knew who rides and uses Wiseco parts has never had a problem. you most likely just installed it wrong. don't rip apart a company for your own mistakes
You don't have to hone in the cylinder every time you rebuild it sad to see that you didn't use No oil i've always use Wiseco don't use anything else because they're all garbage. All of them for strokes two strokes roll garbage because eventually the matter how good you take care of and they're all going to blow up your you're gonna have to rebuild all of them
Hey Austin new subscriber your videos are good and your bike is awesome I was wondering if I could get a shoutout I’ve been working on my channel for the last few couple months hope to get a kx 125 for the summer there’s gonna be a lot of videos on that
@highgearmx Man U get a lot of hate. Why can’t people just let u have ur fun riding ur bike and working on it. I had a blast yesterday working on the bike with u and I’m glad u like my bikes.

A ring can't fall off just wanted to let you know that
I was thinking what the hell this guy talking about ahaha damm hillbilly's.
@@mrpantur7280 haha
Ur bicycle handle bars make me mad lol get some pro tapers

Kelly Ronaghan 😂
So what
i cant wait to get my mini bike running i saved it from being scrapped and its almost ready for a test drive
Donovan Bryant thanks for adding that pointless comment
Number refers to the heat range of the plug. Lower the number hotter the plug and vice versa. Good video dude.

Did anyone else notice the popularity of. the #69?
I enjoyed this so much I had to watch it twice.
That tent space is really cool I like it
The dirty air filter could make it run rich

The floats are stuck
Wow. Look at all that dirt waiting to fall down into your motor. Always pressure wash first. Anytime you blow one up split the cases. You got metal shavings in the lower end. Won't last long. Live and learn brother. You don't need a hone. You need cylinder replated.
You don't have to hone it the bore, I didn't see you use any oil either sadly.
Anyway, good luck with your stuck float.

yeh I agree with rustyskull, I had the same issue with a kx100 and it was a sticky float
RustySkull Productions yeah always good to lube the cylinder before honing it
The ring is supposed to move when you put the rebuild in the rings will still be loose it compresses inside the engine
the number just indicates how hot the plug is the higher the number the hotter the plug yeah a 8 is good its in the middle so u wont foul or bun a hole through your piston
No it's lower number = hotter. Did you just take a guess?
To High Gear MX start watching more you tube videos and it never hurts to buy a service manuel for your bike also, good video and sound.
This helped me alot
This is hilarious
With a single ringed piston you have to replace the piston rings frequently
Im not trying to sound like a jerk off. Im just trying to help you out like everyone did for me when i started wrenching. First off. You used the wrong hone. Ur supposed to use a ball hone.

I use #69 too thats good keep riding Mx Bikes...
Get a polisport restyle plastics kit,I'm thinking if getting it for my yz 125
You cannot hold it out or board out I have the same bike and it blew up on me you have to get the cylinder shipped out and re-chromed because it’s a different metal sorry bro or buy a new cylinder
Take carb off clean all the jets out real good take the float out and make sure the pin is pushing it back up
Love your videos , keep up the good work
nice garage !
Did you tighten up the nuts with the right torque specs?
check the floats in the carb
Check out some new content
Keep doing what you doing I enjoy your vids
The br8 doesnt run as hot as the br9
roostmx pretty sure it's the other way around
roostmx is correct. 8 and 9 is the temperature on the plug. So 9 runs hotter than 8!
The numbers on the plug is the heat range. Its not how hot the plug fires its how much heat the plug retains at operating temps. Also the lower the number the hotter it is. A br8es is hotter than a br9es plug..
Ngks an 8 is hotter than a 9

the one person was right... get vertex ALWAYS for 2 strokes... weisco's pistons tend to cease up after the first 5 hours
Alex Dixon my brother has a 1999 yz 125 that we put a brand new Wiseco piston and it almost 200 hours ago he's been riding it for 2 years straight at 44 to 1 gas mix ratio and we did one heat cycle and then rode the bike balls to the walls all the time and it has yet to blow up
Completely false.
Complete bullshit bro .... weisco # 1 , best piston i ever bought .
toast

hey sorry to say something but you will have to hone it and the piston ring would haven't full off the piston and the ring willnt go down the bottom end I have done all the work on my bikes and snowmobile
whats the music at the start?
Cool tent
The whole money back policy is cool and all but you shouldve just kept the tool cmom
Not being horrible but what videos you been watching it seems like you don't know what your doing lol.
Keep up the good work!
You can see your card in the video id fix that before someone charges it
Stout you can see it very clear if you set speed to .25
U can't use a stone hone on a nickel plated cylinder you would have to get a ball hone done
Do not run a br8 unless your fauling tons of plugs and getting oil out your exaust they make your bike run hotter and if it’s not splitting oil and fouling plugs your gonna blow it up quickef
hey, just so you know you showed everyone your credit card at 14:53
I met your buddy at Durbhamtown
When all the fuel was going into the cylinder your float height was wrong and the reeds petals could be chipped
It also could be coolant leaking in there because petrol/gas doesn't water spot like that
Having kinda same issue floats were stuck fixed that now cant get bike to start what was the fix for this i also havent checked reeds yet
Check the float in carb
I’d say it’s the carb rebuilt ya did
we should go to durhamtown
Heads up teardown starts at 5:00
its just carb issue... no idea what are you doing lol
Ask your friend if he went to durbham town
the floats are probably stuck open
Solid gas?
song at start plz
it's not really a must to hone the cylinder.
+breezeffs jump just wanted to make sure it’s clean and has a good seal
For the new piston and ring
yeah feel you but you can deglaze the cylinder with just wd40 and scotchbrite if you don't have a hone nearby.Why is there gas on the top?
+breezeffs jump cause the bike is flooded with gas I took spark
Plug out to pump all the gas out .. the carb just pours it into the engine for some reason
check your float level. take apart the carb and clean it good. and see if the problem is still there. otherwise you have to reset the float level.when my buddies kx125 flooded like that there got some gas into the pipe so also check that there is no gas in the pipe!
Roost mx has a honer
i had ktm 85 bottom end rebuild and top
if you can see light through them they're bad
U showed your credit card😂
Your floats are stuck open it happened to me when I rebuilt my bike
+Greg Ghiotto I can’t get in the bowl cause all the screws are stripped so had to take it to the shop
You diddnt put a seal on it
Intro song name?
me and everyone I've ever knew who rides and uses Wiseco parts has never had a problem. you most likely just installed it wrong. don't rip apart a company for your own mistakes
The hote the spark plug the beta
“Its the iphone 7 whats wrong with this crap”
You don't have to hone in the cylinder every time you rebuild it sad to see that you didn't use No oil i've always use Wiseco don't use anything else because they're all garbage. All of them for strokes two strokes roll garbage because eventually the matter how good you take care of and they're all going to blow up your you're gonna have to rebuild all of them
First
Take the egsust off and get the gas out of there
clean the carb, its the needle in the carb
has a yamaha,buys all honda parts for it.haaaaaahhh
