    Yeah they said they would look at it but it would take a while ( couple weeks )and I couldn't do without it for that long.

    Blowing the zipper out with air and then rubbing a plain wax candle along the teeth has worked for me in the past.

    Cutting or burning off stray/frayed threads can help too.

    I get asked often about what tyres I use and on this last stint from Idaho down to Colorado and back to Portland I was using Golden tyres GT723.
    I would say I put those tyres through more diverse terrain than other's I have used and a lot was really rocky and other sections were hi speed gravel roads with one long day of 100 deg and slabbing it all day. I got 7000k out of the rear and sure it was worn and needed replacing but I was sold on it. There is no way a TKC 80 would of lasted and had I used a Mitas E07 it may of lasted but would of no way been as good in any of the terrain except the road section. I know they aren't cheap but the fact I didn't have to worry about changing tyres during that section of the trip was worth it and I did get a deal on them so that helped. No to the front tyre. To be honerst I didn't like it at the start as it made my bike feel twitchy and want to go into a speed wobble. This feeling slowly went away as it wore down. The front only lasted as long as the back ( 7000k) so not that great but it did perform better than the TKC80. I did get another set and the front this time although the same tyre felt quite different and didn't have the twitchyness as much as the other so I'm not sure if I just got a bad tyre or what . I checked the balance of the wheel before I took the old one off and it was still good. I had the suspension done after I got that tyre on and no difference. Who knows.

    After the last couple times out on my bike I have decided it's time for a rebuild. She is starting to smoke more than I would like on start up and I have started to use oil between changes so I'll be ordering up some parts in the next week. Currently it has about 854 hours and I have a weekend of riding coming up so it might reach 860 odd and that is probably going to be it for the girl. Now what to do with that legendary piston. Perhaps a little box like you would put a famous baseball in or something huh.

    Maybe it just needs rings! It will be interesting to see what the cylinder, piston, valves and guides look like.:hmmmmm

    No it's gonna need more than rings, guaranteed.

    Never assume anything.

    Pretty excited to see the inside of the motor as well. Have you done anything to it up to this point, like rings? I'd do a shadow box for the old piston with a few pics or a map of its travels as the back drop.

    I am interested in the info on the motor as well. Just sold my GS and thinking a low mile 16 500exc. Not sure of the longevity of the 17/18s yet.

    Why would you think their longevity would be any different?

    Did my 450 xc-w top today. It had suddenly started to use 400cc between 10hr oil changes. Piston was worn at the skirts but no scoring, rings in spec but just barely. Cylinder in awesome shape. Bike has 310 hours and only smoked at start and under heavy throttle. IMG_20171005_123406.jpg

    I'm certain after inspection of the top end that it easily could have gone another few hundred hours with no problems.

    No I have only had the valve adjusted once. I have replaced the clutch plates a couple times.
