    300/440/550 Alternator

    Are these engines able to recharge the battery while riding like a car? I'm just curious if there is some kind charging system built into the magneto. If not, I guess i should be throwing it on the battery tender after every use.

    300/440/550 Will a dying starter crank slow?

    My 440 has been starting great all season until last week. It started turning over slowly. Then the next day nothing. I took the starter off and swapped it with an OEM I had lying around (never tested). That one cranks slow too. Then I swapped in a working Goki and it cranked fine. I took the...

    650/X-2 SX vs JS

    I've been riding a JS440 and JS550 for a few months now. I've gotten pretty good riding them. I'm looking for the next step and I see lots of 650SX around for good prices. How much better is an SX vs a JS? I'm a pretty light guy so I don't think I need a 750SX or SXI Pro. I know everyone is...

    300/440/550 leaking head

    My head gasket leaks water out of the motor. The pistons were seized when I bought my 550 so I rebuilt it. The surface of the head and cylinders had some rust on them. I lightly wire wheeled the surfaces. I got the motor back together and running but water is leaking out of the head. I torqued...

    300/440/550 Dieseling/Runnaway 440

    I started my 440 this weekend after letting it sit all winter. It idled well for a few seconds and then the RPM went way up, like it was wide open throttle. I hit the killswitch, nothing, I pulled both spark plug caps, nothing, I unplug the fuel lines, finally about 5-10 seconds later it shut...

    650/X-2 Pricing an SX650

    I'm new to the sport and want to know what machine I should go with. I practically stole a JS440 at a tag sale. I decided I needed 2 machines (need someone to ride with) and got a JS550 with West Coast parts but a bad motor (thought I could fix the motor but couldn't). Now I'm looking at 2 1991...
