I have just re-assemblyed my TTR raid, after replacing the piston rings. When replacing the cam shafts, as soon as I tighten up the bolts the cam shafts become too tight to turn by hand. Even if I just do the bolts up hand tight they are really stiff. Is this normal? I have completely re-assembled the eng...

Hi there, Just got my bike registered & running well enough to start taking a few shakedown runs on the roads around town. Still more lighting & things to add to before it's inspectable & 100% street legal (USA). Tonight on the pavement, probably cuising in 6th, I noticed that the bars see...

Hi everyone...new to TTR forum, go easy on me! :) Riding the TTR250 the other day I was going full throttle then it died and sputtered to a stop. I noticed right away the battery was smoking and was EXTREMELY hot to the touch. I got away from it to give it time to cool down...acid explosions are not fun. 2...

My 05 ttr 250 makes an awful clunking noise when it cranks and often repeats it when I shut it off. Anyone have this happen before that can tell me what to replace?

I have just started to run 95RON as apposed to 91RON Unleaded in my 97OE, the bike certainly runs better and cleaner i.e. no soot, but has been difficult to start electrically when cold. I don't have a hope in hell of kick starting it. Could this be the fuel or has something else eventuated?

Stopped on a ride today and noticed there was no rear chain block/guide/stay fingy. Bolts up at the rear of the swingarm.

my piston rings were bad so I am changing the gaskets and seals while I am in there. Question is, do I absolutely need a valve spring compressor to replace the valve seals? also, the cam chain sprockets do not exactly line up prefectly. Should I be worried about that? It was running great before it starte...

My 2003 bike starts fine and ticks over OK and it also pulls well when accellerating however at constant village speeds it feels like it may cut out and stutters a bit. When this happens if I open the throttle it will suddenly accelerate almost like an on/off switch, not smoothly at all. It can be lived wi...

I am due to take my TTR for its MOT.

Hi All, Am in the process of doing some work on the TTR belonging to my other half, one of the things I have done is put an airbox back on it as it had a K+N cone filter, which to my mind for trailriding is far from ideal!

I get quite a lot of butchered looms, switches, etc, which require repairs and, inevitably, joining of wires! I am unhappy about soldering joins in a bike loom as it makes a very solid and unforgiving joint from which wires can break. Bullet connectors and the like are OK for joining a couple of wires bu...
