    Dreaded Chain Case Crack Got Me!

    I had the same thought, then re-read the OP's post. He stated oil leaked out and he continued to limp it back. I'm assuming that means it got hot from running without lube and hence why it looks so dry (overheated oil baked on gears).

    Dreaded Chain Case Crack Got Me!

    If you're already looking at adding $2k to a sled you like and concerned about still not having EPS, you could add another $1500 and have that too. It'd still be WAY cheaper than a new one and it'd feel like a brand new machine next season.

    Shock swap

    Fronts and center are interchangeable. The rear track shock is a different length between 129 and 137.

    No Online Sno Check

    On the 137”, there was a change to the rear shock that eliminated a travel issue that was causing the shock body to crack. I think this change happened around 2019 or 2020 and is easily visible by looking at the angle of the bottom of the reservoir relative to the shock shaft. If it’s 90...

    Oil Pressure shutdown

    I'd recommend putting an actual gage on it (temporarily). Oil pressure will decrease as the oil temp rises so it is possible that you have a real oil pressure issue (clearances too high, or pump flow too low) that is borderline with cold oil (higher pressure), but falls below the threshold when...

    Reverse?

    Due to your comment about hearing grinding when trying to shift into reverse, it makes me think the large plastic gear in your reverse actuator (the black part on the outside of the chain case) is stripping teeth. That will cause you to hear a grinding sound when it attempts to shift. Others...

    Wobble Bearing / Upper Shaft combinations for '14-'15 Vipers

    I did the upgrade during the off season. However, I ended up using the 17+ shaft assembly that comes pre-assembled with bearing and brace behind the secondary clutch. I used the standard 6206 bearing and two 2 3/8” internal snap rings to take up the additional 4 mm. I haven’t put any miles on...

    TY Comes Through Yet Again!

    Many incorrectly believe that the shock is what provides the force to extend the suspension. Depending on the type of shock, this can be either a very small truth or no truth at all. The primary purpose of any shock is to restrict motion. Non gas charged shock - these are not charged with...

    Looks like a new display/GPS in the works?

    This looks pretty sweet! Will be great to know if it has group ride tracking built in and if that works sled to sled or if it relies on the phone connection for internet. Also wish they'd make it compatible with Procross, but it looks like it's likely to be only for Catalyst.

    Takes two attempts to start, almost everytime

    Agree with the ECU update comment. Additionally, at that mileage, most are finding the exhaust valves clearance to be well under the spec. I just did mine at 6800 miles and every exhaust valve was at least .003 less than the spec. I have read of many that are very difficult to start and even...

    valve shim chart?

    The poster above is spot on. Make it easy, every change of 10 printed on the shim is a change of approx .004” So if you have a 180 shim and measure .0055, changing to a 170 shim will make you .0095 Also note the typical shim kits move only in increments of 5, but you can buy in 2.5 increments...

    Valve check?

    Save yourself a LOT of time and do the bar method rather than removing the tensioner.

    Recalled Fuel Line Leak

    I used the Yamaha part, but pretty sure they are identical.

    Recalled Fuel Line Leak

    Pretty straight forward, but easier to access if you remove hood. I ended up removing the plastic holder for the old filter too. If I recall correctly, I had to remove the right side support over the tank too, but that’s just 2 bolts.

    Recalled Fuel Line Leak

    I did the same mod before this season on my Viper. It ran all season (about 1700 miles) without the filter and I didn’t notice any adverse effects. The part number I used was 8NF-F4310-00-00 and it was about $25.
