Ok sry for the double post couldn't find my way around this place for a min lol.

Ok I have a 1995 Yz 125 and the bike is a thing of beauty atleast to me it runs great has not taken more then two kicks to start it before the rebuild and after the rebuild was just preventive maintenance and all was beautiful from what the bike shop told me now all that being said I parked the bike for the winter in a heated garage above freezing being the key fraze lol anyways its been warming up and i desided that I would put some new parts on my bike before the first ride of the year like rear tire sprokets and chain made a bit of a change with the sprokets had a 12 tooth front and a 45 rear went to a 13 front and a 50 rear but here is my problem now the bikes starts and runs great even after sitting 2+months starts right up goes into gear no problem and after the warm up i take off to it just doesn't seem to be shifting fine for me hard to explain I just feel it I tried pulling the clutch and all is well in engages but doesn't wanna shift up it seems it will but just doesn't feel right so i tried to bang them by getting on it and just lifting on the throttle and shifting up and it just seems to be fighting me my first thought was i am not used to my new fox riding boots and that was the problem but i grabbed my old ones and its not them so i am at a lose normaly this is where i would just take it to the shop and get it fixed but times are hard I am unemployed right now and don't realy have the money to pay someone for work I can do on my own with a little knowledge droped on me by the more experianced riders and from reading your forums it seems some of you guys know what your talking about sry for the long story thought the back round would help with your answers thanks in advance

Wow all these views and no one can help out a guy stuck in ohio I know I aint from texas but we all have the love of riding and thought I would get some advice I have tried loosening the chain and changing the gear oil but it still seems to not wanna shift into 3rd and so on but i have noticed it is only like this on the roads I have a short ride on the side streets to get to my trails and it seems to shift fine in the dirt just not on the roads.

Could be a tumbler/pawl problem, it could have built up some rust. If it's working fine in the dirt, ride the dog snot out of it and see if it gets better. If it was just fine when you parked it, and now there's a problem, what changed?

I have no clue other then the sprokets and the new back tire and the oil change I haven't done anything else I did take it out the other day to run the snot out of it and it is now seeming that the bike gremlins are getting me cuss it has fouled a plug now and my radiator is leaking I guess when ur luck goes south it realy goes south looks like i will be sitting this summer on the sidelines watching unless I get a new job or tattooing picks up so I can't take it to the shop and have it gone over with a fine tooth comb she is sooo pretty and in like new shape I refuse to ride her untill she is back to flawless again I am not going to ruin her for a couple hours of riding.

To bad your so far away,, I'd trade mechanic work for ink.

Your also 100% correct, have it repaired before you ride!!

I changed the plug today thinking it fouled the plug because it was a old one and all I get now is a backfire threw the exaust and not the loud bang kind the pppppfffftttt kind like its just blowing a silent fart lolI can't believe my luck she has been well maintaned oil change every 2 or 3 rides gas is mixed the same every time was winterized for the winter and now right out of the gate its full of bugs and gives me two small break in rides and now it wont run God must hate me right now I lost my job and the one thing i had to look forward to in my new unemployed status was being able to ride until unemployment ran out and now i can't even do that makes me wanna just crawl in a hole and give up nothing in my life is going right or even close to how it should be atleast I am still healthy and my kids are great and now my wife will have nothing to bitch about but she is a woman so she will find something.

Hey man sorry for the bad luck. Although I cant help you, I'm from Ohio originally and remember riding in Wellsville, Oh and Hillsville,Pa. back in the early 80's when I was a kid. Good times, good times. I've seen videos on youtube lately so apparantly they're still riding there. Ever been? I'm from Youngstown by the way.

yea thats where i ride I am from Girard which is right outside Youngstown I hope something changes for me and I can get to some riding.

When you went up on the countershaft sprocket, do you still have sufficient clearance between the chain and the shift shaft? At speed, the chain may be rubbing the shaft. Looks for indications on the shaft.

I'd go back to the old plug if it worked. The new one may have been dropped and is cracked.

Come to Texas to find friends, work, and great riding!

Ok so I think i figured out what my problem is we think i blew a head gasket checked the compression today and it only has 60 psi so I am purchasing a gasket kit piston and rings new vforce reeds and some other small stuff like a clymers manual I am also thinking my shifting issue has to do with my sproket change not the back but the from when i had the 12 tooth front and 45 rear it shifted fine so I am going to switch back to the the 12 and keep the 50 rear and hope that fix's it otherwise i will just switch both back they are still in good shape just figured when i bought the new chain i would try something new by the way my 13 front and 50 rear is stock so i don't understand why it could be the problem but that's the only change in that area.
