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?

Dan, they have plenty of grunt in the bikes. Thier bikes are basically an SS model. Just no go.

Buy a tank shell.

Actually those that do well in trials do so 110% confident that they can do it. It does not matter if it is the correct method, technique or style. A clean is a clean no matter how ugly. It is all mental for the most part as the geometry of the bikes are able to make it over most anything.

Sprinter 27 advice makes a lot of sense with the cold weather. You could also raise the needle (Which is dropping the clip) That is the easiest and cheapest route, besides it changes the jetting all in the right direction. If you have the time I would do a quick carb clean just to verify the jets are clear and nothing is building up in the bowl. Make sure to note the jet sizes. You could easily go up one pilot jet size without rocking the boat too much. Good luck.

Myself, folding levers are a waste of money and feel like crap. I would just throw them in for spares. Proper lever setup is critical on a trials bike. We had a guy recently use these and he posted the link.

Sounds like you need a carb clean to start with. Pay attention to the pilot jet and circuit. Make sure the needle and seat is good and working.
