    Hello all, long time lurker here, first time posting. Just woke up a '75 250WR from a very long nap. Fortunately other than fluids and fuel system/carb cleaning, it fired right up and runs like a bear.

    My questions concerns the pipe/silencer, it stamped Skyway on the end. What can or needs to be done to quiet this beast down a bit. It's brutally loud. -I'm told there's a silicone diaphragm that when disintergrated make the bike extremely loud.

    Thanks,

    Kurt@trailrider

    Hey Kurt sounds like you need to put some new packing in the silencer the silicone flapper might help a little but new packing will make a big difference especially if there's none in there now.

    I have the same bike. When new, these bikes were loud compared to a modern enduro bike. But they were not horrible. Like dumpbear said, new packing might help. Be careful if you look at aftermarket exhaust, they too are very loud as most you find will be for the CR 250. I bought a Pro Form and it was terrible, ran great, but was very loud. I put a DG type of muffler on it.

    You can still get the steel Super Trapp silencers. Including the weld-on that was installed by the dealer for enduro use
