I have a 1999 yz125 just had a full top end rebuild. Took it for a spin up and down the street and felt like it was bogging everytime I hit high rpm you reckon it could need a carby tune?
If it was bogging then it’s most likely a carb issue, especially on a older 125. It could also be an air leak but that’s less likely. Also a rare case but if you did the piston yourself you could have put the piston in backwards. If you rebuild the carb I suggest just getting entirely new jets that are best for your area. Thanks for the comment hopefully this helped!
If it’s rattling I would first check to see if it’s just the engine mounts are loose and the engine is shaking or if something is just shaking loose. Now if it’s a actual ticking sound you probably have rod knock or piston slap. I have a video where I look at the top and bottom end on a two stroke. It’s called “ piston slap or rod knock “ as far as clutch making noise it can happen. Mostly in Kawasaki you’ll hear some noise from it but I saw your other comment and it’s not common for cr to make a noise from the clutch. If you know the noise is coming from the clutch case area and especially if your clutch is still gripping good and it only happens when you pull in the clutch lever it could be possibly you have worn or notched fingers on the basket.
You ran it so early it sounds like the top end is flooding with unburnt gasoline from the crankcase. Be more gentle and go through more gears for at least 4-5 pulls 1/4-2/4 throttle and then try it again. Although it would take the abuse its not good for the engine, I always wait for the cylinder to feel warm to the touch. You also cold foul plugs fast when trying to rev and the engine "barbles"(dont know the word in english :D )
It’s always been a large debate on if you should warm up a Two stroke, some say you do others say it gunks up the carbs on the older bikes that have them, either way it really just depends on if you got the time to do so. The clips shown are also shortened and doesn’t show me propping up the bike while it idles to adjust camera settings. I agree sometimes you need to warm up a bike more than other times. This bike also had plenty of issues not focused on in this video and could be cause for the sound you hear, especially with the jetting on this bike. Thanks for the comment however!
@@sameryounis909 it is 100% quicker to remove the engine just keep track of the wires and bolts and you’ll be good. It can be intimidating for most to see the wires and taking the heavy engine all the way out, hints why I made this video.
When doing a wheelie sit, use the rear brake like it's your best friend. It will never let you down. Practice in a nice place with grass if you can. It will take one a few hours a day for about three days. By the third day and you will have the tipping point down pat. You have great rider style man just practice sitting and tap that back brake when you start to go past the tipping point.
Step one, pressure wash engine. Step two, remove skid plate... Not sure why you removed one radiator.. Glad everything worked out but I remove the engines and don't get everything all boogered up including the collar. Removing the engine is super simple, all the time spent strapping things, twisting, cranking, etc. you can have the engine out and do it right...keep that in mind next time.
Looks like you trucked into location... is there a large elevation difference between home and where you are? That really sounds like it's too fat to me. Drop 2 jets. I have always gone with 1 or 2 jet sizes down for every 1000 ft elevation gain and the opposite when dropping elevation. I've crossed from 1,200ft to 6,000ft start to finish on my banshee and it is a total pig at the summit. EDIT: Just saw your pinned comment...🤦🏻♂️🤷🏻♂️ So what was wrong exactly with the carb?
Thanks for the tip, there was a difference in elevation and I’m not sure by how much but my carb has been leaking and bogging pretty bad, I think the float is stuck open. But I had to get the race done one way or another so I decided to just go for it. I think it’s time for a smart carb lol because it really messed me up during the race
@@ChaseAbbott45 Never tried Smartcarbs, my cousin has Lectron carbs on his banshee. Metering rods are definitely a better option than jets... I just can't justify the price. 👍
For those wondering the carb is messed up, made it a rough race and hard to keep the bike alive but I had to continue, couldn’t stop on the first round of the series lol.
That’s how they were before I pulled it off, the kid I bought it from that day didn’t know what was wrong with it, just easier to show in the video with the basket removed.
I have removed the starter without removing the engine, but tbh you're only a couple of quick steps away from pulling the motor anyway. And it's much easier to clean and work on everything.
It definitely would be easier to remove the engine and work on it as you’ll have more room but for me I didn’t really know how to disconnect the wires fully lol, because I’m still learning, and for some people when they hear they have to remove the engine for a project it can be intimidating.
It’s a 2003 Ktm 250 exc, i think that it just heat seized and the c clip snapped. It was weird tho because the whole engine only had 3 hours on it with new fluids.
@@watermelonwatermelon6513 Hopefully that is the only issue with it, It was my brothers bike so I'm not sure what mix he used for it but I run 40:1 race mix in my bikes.
Is there a steering damper under that bar pad? If not I HIGHLY Recommend a Scott’s 👍🏻you will never ride without it again once you get that Golden Nugget😉
I don’t know why I didn’t think of that, most of what I ride is just a lot of rocks, I’ll definitely have to get one. Thanks for the advice it’s definitely gonna save my arms lol
@@ChaseAbbott45 It really is a great piece. I’ve used them for 20 years and ride CT single track,Thomaston,Union and a couple “ninja spots”.👍🏻 Pretty much just look out for stuff taller then 10” on the trail,other then that I just aim for the big rocks too jump over the bigger or smaller ones😀 be safe👍🏻
