Sounds like it`s not venting. Take a pic if you can.

The only thing Torrot shows was the 125 took a 52 pilot jet. So what elevation are you riding at?

You are in trouble. That is all F'd up. Looks like a new crank will be needed.

Just your luck, but the hoses are starting to age. Good Luck.

So So you did know the '22/23 models do have a fuel pump issue. Lots of them had to be replaced. The 301 is very critical to rpm idle. I have more than most as I ride from 2500 ft to well over 13000 ft elevation. Intetesting read though , thanks.

With all this thought and logic, what are you trying to figure out? At 1700 rpm the bike is not producing enough current. The bike is happier near 2000 rpm.

That`s long ago now, Maybe 2013.

We had a member replace the whole transmission at 7 months. I want to say it was a 2012. Always something with the Pro motor. Great motor when it is running!

My son actually broke 2 gears in my front yard. He endo'ed over the bars. When the bike hit the ground the rear sprocket hit a brick that he had been using as a kicker. The engine was sill turning, knocked the chain off and wrapped around the front sprocket. One we got the chain off, we realized the tranny was locked solid. The next day which was a Sunday morning, when I split the cases 2 broken gears fell out. Monday I overnigjted the parts and wednesday I got the bike back together after work. We left Thursday for a 2 day event and my wife bought him a new bike on Friday! That should have been our last Gasser. I now have 2 more for my grandsons!

I guess you never read through the gas gas forum. Ever since the pro motor came out in 2002 it has been the most defective transmission in modern motorcycle history. So much so they changed the cases to where you could fix the tranny without splittinv the cases. Usually its the kickstart gear or the shift shaft breaks inside the drum. You are just unlucky. Good luck.

I had just assembled a brand new 1995 Fantic section that would not shift at all. After a couple of days of checking the easy stuff I split the motor. I found nothing wrong at all but a blued shift fork from forcing the shift. (Side note, it was assembled without a base gasket from the factory. Plus for the tear down.) Replaced all the shift forks and reassembled. That bike never, ever had another mechanical problem. Just goes to show not all issues are clearly evident. You might fake putting the cases together to get that motor to shift through the gears before the final re - assembly. Good luck.

The shift shaft would break loose at the weld. You did check that?

You do know that you have to spin the shafts to get them to shift.

Did you have a shift shaft problem first?

Well you are correct on that stock it is lean. All the bikes stock come lean from the factory. The Gas Gas forum had a lot of that info. It all depends where you are from as the fuels can be different. Seems in the .U.K. they were big on changing the slides on the pwk. But I think they also showed a different needle. In the states we usually just increase the pilot size, but our fuel is different and we ride higher elevations. Hopefully someone replies with a thought on the needle.
