How do you adjust the clutch on the front of the engine? I bought a 250EX for my daughter and it slams into gear. What can I do to soften it up? Do I increase the play?

Thanks..

 

Sounds like the idle rpm is too high. The centifical clutch doesnt start to engage until 1700 rpm. To adjust the clutch (really the freeplay in the linkage)warm up the motor, then with the motor off,, loosen the locknut, turn the slotted screw CCW, until it meets resistance. Go back 1/4 turn CW, and hold the screw from turning while you snug the lock nut.
What type of oil is in the motor? Automotive oil, or motorcycle oil?

 

Not sure.. I jsut bought the bike, what do you suggest? Now that you mention it, the idle is a little high when the unit is warm. It is a little low when the unit is first turned on, but I guess that is what the choke is for,..

Pick a motorcycle specific oil that is API SG/JASO MA. The MA thing insures that it doesn't have friction reducing additive that will harm the clutch, and the SG thing insures that it has high pressure additives that will protect hig pressure areas like the transmission and cam.

I like Maxima's products. Their Premium is an economical petroleum oil, they also have a synthetic blend, and my favorite is Extra which is an ester synthetic.
