Hi all . New to the forum. Just after some advice. Just got a mk2 crm 250.. seems a bit slow . Checked the power vavle cables and that under the rc cover . And it moves. But could it still be faulty ... cheers .

When did the bike last have a freshen up? New piston, rings etc? Just check the valve opens right up and closes, has a wee mark where it should be set to. This is in the faqs

Whats the compression like?

Also could be something silly like carbon build up in the pipe
