Are there any tips or tricks to reducing vibration? After taking a test ride on a new ktm 400, I noticed my old ktm 250 seems to vibrate alot. A friend took a ride on the 250 and noticed it also. All the motor mount bolts are tight. Flywheel is tight. Thanks in advance for any advice.

Check the pipe mounts and check the pipe to cylinder junction to be sure it is tight and has new/good O-rings. A worn piston or worn crank/rod bearings can also create excess vibration.

That's a good idea. I just put a new pro circuit plat 2 pipe on it a couple of weeks ago. After the first ride with the new pipe, I checked for exhaust leaks around the cylinder but did not find any.

You made a good point about the o-rings. I used the old o-rings off the stock pipe but I have couple of new ones. I'll put the new one's on and see if that helps. Do you think I should use any high temp silicone along with the new o-rings?

Thanks.

Silicone is always a good idea. Clean off both surfaces and put a nice layer on the pipe mating surface. You don't need high temp sealer since it doesn't get that hot. Orange is a nice color for bike bodywork plastic but not for silicone sealer.

Emig Racing sells some vibration damping inserts for your bar ends. I have not tried them yet, but it seems like they would work.
