Think we've sorted it! Put a new O ring on the air screw, had a test run but no difference. Put in the new pilot jet and went out again. Bike better but still sputtering at low revs. Air screw was set correctly at 1 and a quarter turns out so came out another half turn. Instant improvement. Out anot...

Hi Ya Mickstoy. Jets are standard according to the manual. Just found a possible cause / fault with the air screw though. Found the O ring has perished, could be letting in air I suppose. I'll repair and try bike again. Thanks

Thanks Gwyn. Very little dirt / muck in the fuel filter. Think the black bits were coming from the float bowl seal. Someone had put sealant on there! Cleaned it off now.

Nylon bristle pushed through all clear. New fuel pipe and inline filter fit. Bike rebuilt. Took it for a test r...

Help!! Only had the bike about a week and noticed that occasionally the bike runs very erratically at low revs. Not like that all the time. I've had the carb off, cleaned it out and jets blown through with compressed air. Checked the exhaust valve and it seems to move freely. Ran bike with AR cover ...

Hi Ya to you all. Just a bit about me. Current Firblade owner and ex moto crosser. Feel the time is right to slow down a bit (gettin old) so started lookin at Trail / Enduro bikes. Came across a test of a CRM and fell in love. Just what I want, light, torquey and most of all a two stroke. Still look...
