Did you ever replace the spark plug cap and trim the wire back? You might check the pilot jet again just to make sure it`s clear. Or just lay the bike over till fuel spills out the carb. That is the quick way to prime the engine.

He keeps bouncing around with his thoughts. Sounds like it is electrical, with the slow fan. He never has said if it starts and stops(the fan). But if he is actually riding it around and the fan is running and there is no leaks, it has to be no movement of the coolant. Especially being winter.

This is his 6th thread on the same issue.

I removed mine in a split second when my bike and I parted ways. Like twenty feet off a 6 foot drop during a National last year. I was 4 miles out of a 9 mile loop. I picked up all the bits put them in my fanny pack and taped the wires up separately. I have not touched it since and my bike looks better without it.

The oko`s fit and just a tad larger than originals so better. I did see some on a carb site awhile back, but did not save the page.

Actually those were mainly the bad years for Sherco due to the rear mounted fuel tank, fuel pump run by vacuum. Buy newer or consider a Beta.

The mixture can't be fixed on the outside of a plugged carb.

The only thing you need is a good carb clean. The pilot jet is probably plugged.

Like a rod, side play is ok. Anything else not so good.

I don`t recall mine as sloppy, but I have gone 10,9,10,11 and back to nine. So five sprockets on a 2016. It could also just be the brand.

Just remove the lever and pump it with a phillips screwdriver. With the lever out of the way the piston should return all the way. If that does not work, remove the clutch line from the M/C and see if you can get fluid out of the m/c.

Well at least it is winter!

Check all thd pins in the cdi connection. We have seen a few that were out of place, not making a full connection.

The plates are probably just stuck together. Point it in a good direction and ride it with the clutch pulled in until it releases. It helps to use the brakes and/or a wheelie or two. Sometimes takes 10-15 minutes.

The Gas Gas pro model has always been hard to start. It takes a technique, you cannot just kick it over and over again. One of the issues, it only has a partial kick start gear shaped in a half moon. In fact my last Gas Gas was bought from a guy that could not start it and he makes his living riding bikes hundreds of miles a week. The 55 pilot is a step in the right direction. Helps to get the piston to top dead center, then a very quick short kick, You also always need to make sure the kick start gears are engaged or the gears will chip.

Nothing will bleed in either direction if there is no free play at the lever, which is usually the problem in the first place.

Bullylover is spot on that it is in the pilot circuit. Better to waste a few hours working on the carb than throwing money at a bike that looks better just sitting than running.

You are basically carrying your wheelie over it. You have to hit lower on the rock with the front tire.

If the water pump and fan work correctly, no head gasket leaks and no water in oil or no oil in coolant. The only two things left is a blockage or air lock.

So you have a fan issue. Did you ever just hook a battery to the fan? So when you checked the impellor, did it spin when you kicked the motor? Did you try spinning it with your finger? The threads can strip, so they never push enough coolant.

Did you ever get the fan spinning at idle?

I`d go with 475 or 500, depending on your container size to get two oil changes out of it. The 550 was a dry motor.

The 1993 engine was completely different.

Maybe time penalty vs actual score.

I thought `93 was the first year of case induction on the 250?
