Hey, I'm struggling to jet my 1995 250 Raid. It has an FMF powercore 4 exhaust, and has had the top of the snorkel cut off. Can anyone advise on a good pair of jets for this setup?

Well I thought my bike was running rich as the spark plug has a sooty black appearance. ( not shinny black) However I read that if ur exhaust makes a popping sound it's lean.. My exhaust makes this on deseleration. ( i always thought this was maybe a bit of extra fuel burning). Any ideas?? The exhaust is an...

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 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 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 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...
