You don't have to take the swing arm off the bike to replace the brake lever off but it' a good idea to take it off and check if it's not rusted in place and grease it Guy

I cleaned a few muffler by burning them, but I never '' played '' with the baffle, I have a couple on the shelve coming from different basket case I bought a few years back. That's why my comment started by I don't think. Good luck with the cylinder, I will quote a famous personnage again : '' Patience my friend, happy you will be when work is done ''. Guy

I don't think you can burn the tail pipe. Guy

About noise, I had just rebuild a D model, on start up it was crazy noisy. Lucky for me, I always use a lot of 2 stroke oil when I reassemble a cylinder. I noticed that the baffle ( the last piece of the exhaust ) was not '' smocking '' very much, but most of the smoke came from the joint between the muffler and the baffle, cleaned it and voila, normal sound Guy

I do agree with copemech that they are '' noisy '', also Nikasil ? What piston are you going to use ? I'm sure there is a cheaper and more standard way to fix your problem. Guy

Look like the sleeve as been changed and they '' matched '' the new one with the cylinder Guy

You are right about the 311 piston, and yes they are a little heavier than the 434, but the modification is easy to do and I have not notice any difference in performance in 2 bikes that I use them on. I posted a picture a while back of the 2 piston side by side. Guy

It depend on the state off the sleeve Guy

Thank's for the reply I have a little experience with bike, but I know very little about Gas Gas, I've seen a few picture off frames with crack, what about some with a red cylinder head ? Guy

I'm going to look at a 2009 250, anything I should be aware ? Is there a problem with the frame ( crack )? or anything else ? Guy

Nice Alpina, David Guy

You have to give them credit, it's kind of one part fits all Guy

If you have a few days to spare, I can tell you story that will keep you awake laughing for months Guy

Just screw it in Guy

Look at the parts list avalable online, you will see what is missing Guy

About that swing arm, anybody remember the Kawasaki '' foobar '' road racer in the 70's ? Guy

Don't forget, you don't change the oil, run it around the backyard for 10 minute and decide. Changing type of oil take '' sinking time '' to show it's quality. Guy

I'm not sure about the way that line is setup Guy

From what I can see, that is not a TY rear wheel. Guy

Picture, please Guy

I installed a set of Gold Valve a few years back and here's what I think: They are not the ultimate thing, but for me, they made a difference on rough ground at low speed the way I set them up. You get use to them quickly and don't fell any difference until you test standard and modified forks back to back. My TY have longer and inclined shock so the steering is a little steeper than original. Are they worth the money, before a long ride no after yes. Guy

Many things to consider : the size of your hand, I have small hand, can't use some type of levers Type of grip : some are bigger than other. Do you run with one finger on the clutch to operate it Is your levers adjusted to your finger length, not only the '' slack '' in the cable, but the actual position of the lever on the bars Is your cable in good shape, I have on my TY 250b a lengthened arm under the motor and still had a hard clutch pull until I change the cable Guy

Sorry Vforce Block Guy

The adjustment is behind the ignition cover, if you want a smoother clutch try a longer arm under the motor. Spacer between the intake and the cylinder and lower and back footrest. Guy

David, do you feel that the Majesty Damping Rod are better on rock bed and rough downhill than the Gold Valve ? Guy
