99 wr400

Recommended Posts

Picked up a 99 wr400 today. Got a few questions. 

1. Bike has an fmf power bomb header and exhaust. The muffler is screwed up and wanna replace it. Its a slip on style with two springs that hold it in place. Whats an alternative muffler to replace that one? Dont want a super loud. 

2. They put a new piston in the motor. Wanna check the timing to make sure everything is set right. I pulled the motor out of the frame to clean everything up. 

3. Good source for oil line replacement.

4. Electrical diagram. Not gonna run a head light or tail light. Just wanna make sure nothing will get messed up. 

5. On the side of the motor above the shifter there seems to be some kind of sensor. Is this a neutral saftey?

I'd run the FMF Q4. Pretty quiet when you're not on the gas hard, but still has some bark.

The powercore 4 is a bit cheaper and louder, but you can buy the optional quiet core to make it reasonable:

Yes, that should be the neutral switch.
