    Sidewinder Year to Year Performance

    The SRX wasn't geared higher than other models aside from a few that had 24/50 like the LTX/LE

    Chaincase oil seals depth

    That's a 6206, but yes I agree with what you're saying. The numbers may be in there but not a guarantee it's the standard version.

    Chaincase oil seals depth

    Notice how Yamaha codes the '6205' in the middle of their part number.

    Weight transfer with snow trackers

    Did you try loading the front shock springs more? Why the 'very light' setting.

    Chaincase oil seals depth

    The top inner bearing is a 6206 open, while the top outer(cover) bearing is a 6205. The lower bearing is 6205.

    Chaincase oil seals depth

    There are a lot of metal filings that come off the teeth of the gears and chain over time that cause the bearings to develop a bit of a growl and roughness. It's debatable which way to go with seal placement.

    Chaincase oil seals depth

    On the factory setup, the bottom bearing gets no oil, it just just relies on the grease. The seal would be just in case any oil were to get by the one seal in the bearing and also to keep snow and water out. The top bearing has no seals so that seal does in fact keep oil in.

    Chaincase oil seals depth

    I put them in the middle of that shouldered area that holds them, or I'd estimate that to be about 3-4mm back from the bearing.

    Knockout kit

    But there isn't any oil running through there.

    Knockout kit

    I recently had difficulty removing a stub shaft. Once it did come, there was a surprising amount of rust on the splines. It's really to bad Yamaha hadn't routed an oil passage to feed this area with a steady flow of oil. If they had, this thread probably wouldn't exist.

    Knockout kit

    I have no doubt that it works Bob, but I just hate adding any weight if I don't have to. It's not cheap either.

    Knockout kit

    I haven't got enough miles on as this winter hasn't been good. I've put this on about 10-12 other machines so far, and positive feed back so far, but again not huge miles. The logic certainly makes sense in that if there is grease on the splines it will reduce metal to metal contact. I can't...

    Sidewinder Year to Year Performance

    The deeper the track, the more it behaves like the Baker tractor dyno.

    Sidewinder Year to Year Performance

    You're right that the SRX version was designed for more top speed with the different springs front and rear, and calibrated lower total height. One inch track also. I forgot about that. There you go @Simplespeed

    No MTX ?

    Back for 2025 final edition.

    Ok, we're all ears.

    I don't think it matters which rollers.

    Well guys after 19 yrs I've jumped ship.

    Ok thanks. I do agree the ergos on the Polaris are slightly better than the Winder.

    Sidewinder Year to Year Performance

    There's no difference that I'm aware of except for the clutching specs that were different on 19's and up.

    Well guys after 19 yrs I've jumped ship.

    What I meant was why not a Winder that be bumped to 260 with just software on pump gas and 280 with a high flow muffler. Maybe you were never a Cat fan, but don't mind Polaris? Just asking.
