    BWSwamper,

    You are right. There is no way that the fork seals are going to be the same for the '85 and '86 Z forks. It is very common to see them listed as being interchangable.

    I don't think that it is too odd that some vendors don't know the difference between two model years of an out of production, quarter-century old three wheeler. I think it is VERY strange that you and I do.

    The three wheeler aficianados swear by the Yamaha fork seals. They weren't really made by Yamaha, but their price suggests that they are a premium product. I seem to have the same luck with Vesrah seals and put the savings towards beer. After I have enough beer, I don't care that my fork seals are leaking.

    I just replaced mine. And the rear. Went to local bike shop and got the shortest 530 o-ring they had and a 17 dollar breaker from harbor Freight. It's enough to do 2 bike's but not much choice. Picked up an extra M.link for the next change too. 2 new chains made a big difference. The original's were still on bike and guy at counter held it up and it sagged so bad they laughed...I told them it's a 28 year old chain off a BW. They all liked that.

    Hi Röhrich,
    Those are cool, It looks like both have extended swingarm's for whatever reason they used them for, maybe hill-climbing ?
    It make's them look like stretch versions of what I had in mind.
    Wonder if he had a BW swing-arm if it would have ended up different.

    Put about 5 hours on the 350 today in the 90° Florida heat. Ran great except for a lot of engine noise that I think may be valves??? Anyone run had to adjust valves? If so how difficult is it. I have not had as much experience with 4 strokes the only valves I have messed with were reeds. Going to check out the manual, but wanted to get your advice first.

    Hey all, still not much new with my BW but I keep finding great little gems that force me to accept the fact that we are a odd bunch of enthusiasts with a common interest in strange and quirky bikes.

    Found this video on LiveLeak yesterday and had to share with you.

    Enjoy :-)

    Boscrowe,

    Welcome to the island of misfits and broken toys. Of course this is exactly where you should be hanging out.

    Did you do all the fabrication yourself? Actually, it once crossed my mind that Polaris has most of the parts laying around to build such a machine.

    Yeah man , custom built from my garage. Its only at the testing stage as of now . And last night added another link in the trans /jackshaft chain then put in a chain tensioner and its riding really good . Next is some rear frame cut and fab . And I'm thinking a differnt gas tank. No shift is kind of nice .

    Sad days indeed.

    However, serious bidders often wait until the very last minute and try to sniper the sale. That keeps the price from being driven up artificially and the early bidders are usually just bidding for their recreation.

    I wish you weren't on the other side of the continent from us up here.
