Since I bought my TTR a couple of years ago it's been a bit spluttery cold and less pickup against my son's TTR, I have done the normal stuff x3 times or more. Then looking through the parts list Brian mentioned about pilot jets being difficult to clean, so I ordered up a couple of replacement jets a bit lar...

Hi everyone, another problem again. After my spirited riding at the MX track last month, the bike doesn't feel the same. At about half throttle, she develops a splutter which leads me to think about fuelling issues again.

But I also noticed that the compression seems quite low, I can near e...

I was cleaning some axles and snail cams this morning and came across two snail cams different to all the others. These have raised corners as shown in the pic above. All my others are dead flat.

Hi all, The front brake lever of my old TTR is broken, allowing to be actioned only by 2 fingers. Adding to that, it seized the fluid return 2-3 times.

I was having a tidy up and came across a brand new black seat strap of the same design as the TTR seat straps but significantly shorter. It's 39cm long compared to the standard 55cm It is way too short for even a fully lowered OE seat so what could it be from? I know the Raid seats have seat straps and there w...

I would be interested in other owners views on the foam lining on the TTR's side panels. On a dirtbike, the foam is a PITA. 1.
