  1. Is there significant difference in shock lengths for EXC 450 (530) 2008 vs EXC 450 (350, 500) 2017. Besides length, is this an interchangible bolt on job, or are they completely incompatible. Story is about fitting 2008 TTX to 2017 350 bike.

    Is the pdf file for exchange valve setup still available anywhere, would like to compare it to mine and soften it a bit.

    Beta 350 Sach rear Shock revalve help?

    Kyle Tarry, did you remove ring shim on your rebound or was it non existent from new?
  4. Luckily no heating was needed, till I tried to remove the dowel to derust it. Even then it was a pain to remove, with properly heated case. General problem is, the bolt hole comes out of the case, so water can enter and rust the dowel. Will prelube and fill the exit hole with epoxy.
  5. Managed. All bolts were removed, but front dowel was seized. Luckily, I saw a video of dowels exact location, so I could tap at the right place, just below water passages. Came of easily. Heating would probaby interfear with plastic waterpump gear.

  10. Undone all bolts, managed to get it loose. Clutch removed completely. Rear side, at kickstarter is free, but front, at the waterpump is stuck. I did get it out a couple of mm's, but is a very unresponsive and metal twisting sensation. Is there sth else, manual is not talking about?

    Values I could measure with multimeter, were spot on. Magnet visually seems close to yours - battered. In the past, bike suffered a lot of sudden stops, resulting in magnet rotations on the crank. All parts, except magnet were replaced back then. Magnet really could be worn out. Since it is kokusan magnet, could it be replaced with other bike brand. I know wr 450 has similar flywheel.

    Tried different coil, measured resistances in pickup and original coil, all elements seem fine. It might be CDI, as cables are OK

    Absolutely true on that one. Hardened, burned like, broken plastic

    Not sure on the mechanical part problem like woodruff. After some time of haul starting, bike began to kick start normally, but it is not the case anymore. It seems like it needs a major electrical hit for some part to get enough juice to start the bike. Then it idles and pulls just fine, untill you stall or stop it. So mechanics like rotor phasing are OK. Did you see the spark in the video? wiring is OK, bike works when it is started by towing.
