The `04 had a 4 bolt rear sprocket, kind of orange/red graphics.

The stock looking one sure is nice. But when you are sliding off an obstacle, it`s hard to beat the old flat simple one. The sleek looking one tends to throw you off to the side. That one from ty trials would do, but you could always have one made to your specs.

Brakes are contaminated. Question is, brake fluid or ? You could always do the water trick. Heat up the bakes up and down the road and dump a bucket of water on the calipers and rotor.

That`s enough to start the bike easily with the kick starter. And yes a flooded bottom end will make your life miserable. You should be on the right track.

You have adjusted the piston on the M/C too far in. Now it`s not releasing. Back the adjuster off until you have some free play between the lever and the plunger.

The crankcase drain bolt usually is never used, but should the bike ever be submerged it sure is useful!.

My 1974 Ossa Explorer. Yes. Taken Nov. `74. Candy Apple Red by me. And it came this way! Kind of strange, looks like an MAR. It was an explorer frame and Explorer on the title.

No, it was a 450.I remember the test ride in Cycle World or Dirt Bike. Never remembered the right hand shift. Interesting.

Go to the Beta USA web site and use the Evo work shop manual as it`s basically the same motor. Otherwise just ask on this forum.

Do a compression check. Pretty sure your top end is about done after your last post. Hard starting is a sign of low compression .

This is the one I find interesting!

Yellow shock or spring? At the same time your 4rt could be sagging pretty good. I was noticing that yesterday with 3 older 4rt`s next to 2 brand new 2016`s.

My son last weekend.

Sure you had a little blow by. That happened at full throttle with a cold motor. Remember you can do a 250 or a 290. The 250 Rev`s better especially at low elevations.

Just pull the cracked piece on the pipe up a little to line them back up. Put another bolt in to weld it up. By the way are you missing the spacer between that broken tab and the frame?

Yes it`s normal, but there is a mod with an rd 400 manifold. Also replace the small o ring on the nozzle and the o ring on the banjo bolt.

Water in the fuel? I believe the petcock can be cleaned on the 175.

It is called a cold seizure. A warm engine might have survived. Remember to always check for the clunk of the slide closing completely when working on any bike. http://www.shercousa.com/pdfs/sherco_top_end_maintenance_manual.pdf

The manual has some pretty good basic starting points for your weight. Push hard on the center of the bike (seat) and make sure the front and rear are moving together at the same time. Trials suspension is usually on the soft side. http://www.gasgas.com/Pages/Technical/trials-suspension-tips.html

You nicked the piston. If you remove the front pipe, you will probably be able to see the rings are now stuck. If you are lucky you might be able to clean it up. If you have aluminum stuck on the cylinder walls, use muriatic acid with a small brush. It will dissolve the stuck pieces. Keep us posted.

Dad of Two. I remember a very nice 348 do a wheelie in a section and the front forks pulled away with the tank. Incredibly the fuel line came off the carb about the same time the spark plug cap pulled off the plug. It burst into flames as the head stock broke from the rest of the frame! Was just incredible the timing that happened. That was twenty years ago. By some twist of fate I became the owner of that bike several months ago. I hope to have that bike running again for our vintage events this year! On the Sherco side of things, my son just bent the crap out of the bash plate on his bike. Waiting for gaskets. I knew this was a problem as the frame bends easily and the plate is very soft. Looks like I`ll be re-bending the skid plate at least once a month. I`ve replaced the Top cylinder mounting bolt 4 times till I got one to hoId. I tried Loctite blue, then red and finally just got an extra long bolt and it held. Damn 18 year old kids thinking they can splatter every rock they see!

GM auto trax is blue. We used to use it in the Gasser pro motors.
