Revving like crazy in idle (1993 CR250)

[B0000M]

Well I finally had some time to look at the bike over the long weekend, turned out the bottom bolt holding the carb -> reed valve plate was missing and the 2 ones on the side not even finger tight (also missing the gasket).

Bikes running mint as now.

the concering part is this question:

where is the missing bolt?

I think he meant the manifold bolt (external) was missing, not the reed stopper plate (internal).

Yeah thats the one, external bolt had come off so must have fallen off in a ride.

Went out to woodhill on saturday with my mate on his KX, they have set up a new entry and now costs $25 to enter (only had $20 on me but they still let me in). bike was running great, but still had to change a plug...been thinking I need to purchase a proper trail bike as I hardly ever hit the power band around the tracks...guessing thats why it keeps fauling plugs.

The older two strokes were defianitely more tempremental when it comes to plugs, but i'm sure if you get someone who knows what they are doing to jet it properly it should be ok.
