Just recorded a vid of my TTR - just got it last week. Sometimes there's a heavy clunk when I kill the engine, sometimes no clunk, sometimes just a small one. I'm hoping someone with experience of these things can shed some light. Thanks, Paul -- Edited by PaulF...

Heidenau K60 in 130/80/18 on the left. Pirelli MT21 in 120/80/18 Michelin Tracker in 100/100/18 on the right. These are the only tyres I've tried so far so the comments are relative to these three tyres in UK conditions. I am searching for a green lane/TET tyre. Heidenau's were comfortable and fun on r...

I've only just got my 2001 TTR and have noticed a problem with the speedo. When I take off for a ride the speedo needle doesn't move but the odometer is clicking over, which suggests to me that the drive cable is doing its job. After some time and a solid whack on the speedo it jumps to life and is OK for the res...

Still getting a jet black spark plug after carb refurbishment where I replaced all rubbers and jets and adjusted fuel/air mixture. What could it be other than the carb? Or could it be I need a new carb all together?

Stripping down an engine tonight, I used the "jam the sprocket with a socket" technique - worked a treat An odd thing, the nut needed a 32mm spanner (I haven't got a deep socket that size) and I am sure that nearly every other sprocket nut I have encountered is 30mm I will try and remember to check it out...

If you can lay your hands on a 10mm bearing puller, then there is a good chance you can remove your rear shock bearing collars without any damage.

When I was out today on the TTR it didn't feel right on turn in ( 80-100kph on dirt roads ) so when I got home I checked the swing arm for movement, seems ok, grabbed the forks & they seemed ok as well.

Hello All! I have the rear shock out of my bike for a new upper bearing, and decided this would be a good time to check to make sure the strut is still in good working order.
