Vintage Dirt Bike Q & A

200 main and running real nice didnt have a chance to pull the plug but will do it in the morning. It was just a touch to black and not at all wet with the 210 so I think the 200 will be perfect. I still dont understand why this pipe is jetted so low I want a different pipe as I think it will make a difference. I got the liscence plate for it today and am gonna take it for a spin around town tommorow if the plugs a nice color.

It has a leaky right hand crank seal. I can lean the bike over on its right side and it leans way out stand it back up and the idle drops back down. Pretty sure its sucking crank oil when its standing straight up and its sucking air when its leaned over as the oil is sloshed over in the side of the engine. Who knows where to get crank seals cr mr or mt will all work as far as I know, its for a 250.
