    I think there are a few people looking for air box pieces. If you're getting rid of stuff, I'm sure one of the members here would take them.

    What did I miss?
    What are you going to use the swing arm for?
    Building something interesting?

    Ah yes...the airbox too I'm keeping. The one I have, the plastic stud is broken off and tabs on top are gone. Too bad it's such a miserable job reinstalling them!!! My existing swing arm is bent or crooked...I have to squeeze them together to install the axle and even then I can only tighten the nut so much.

    That's odd. I remember you writing about that now.
    With pipe, when we need it to bring it a certain way, an oxy-ace torch with a rosebud tip can be really handy. Just heat up an area in the shape of a diamond. It'll come that way a bit.
    If you did that on the indide of both sides of the swing arm, you may solve your problem.

    Redman66,

    The Tri-z triple is a bolt on to the BW frame, but has a greater rake. The rake is more extreme with the 86 Tri-Z triple and forks than the 85.

    The BW triples can be bored out to accept the 85 Tri-Z fork tubes. But the larger diameter 86 Tri-Z tubes would require too much material be bored out of the BW triples.

    "HRE" has done a lot of these bore out jobs and doesn't overcharge.

    The 85 Tri-Z tubes are 35 mm. 39mm is too much. Not sure about 37 mm. Mike at HRE will know.

    Here is a link to HRE. They do a lot of three and four wheelers, but are familiar with Big Wheels and the various front end mods.

    And on the front wheel, same rim, different hub.

    The holy grail of the BW350...

    Of course, after I took the pic, dropped it!!! Cracks add character, right? Damn, they're so fragile with age and sun exposure.

    But, there must be a way to cast a small number of these for low cost even if they're a solid amber colour and not translucent.

    You're right. That's why the stock ATC250R forks were used with the stock ATC250R triples on my BW instead of boring the stock BW triples out, but I do believe some folks bored the BW triples to accommodate the Tri-Z forks.

    Spent yesterday harvesting what I needed for my machine....spare wheels, airbox, plastics, swing arm, tail light, etc. Here's the stuff I'm parting with.

    Brothers!!! How the Hell are ya???

    Found a complete front end on eBay from a 1983 ATC 250r , thing is he wants $980 Australian to supply and deliver.. Bit pricy or what?? guess they are getting rarer but hey fair suck of the sausage. thats up there. hahaha Might see how bad the BW front end is first as i am barstardizing an 1997 XR 400 into a Big Wheel. On second thoughts STOPPING might be a priority... lol

    goodly satisfactory place, qld
    Watch those atc triples some have rake built in.
    I am building a smaller honda into a bw fatcat style of bike.
    I have a set of those raked triples,which are no good unless the headstock is the same length as the donor or you get creative.
    I ended up with atc350 triples which aren't raked.They take 35mm fork tube which i have a few off[cr80].Add a chinese quad hub...cheap$$ and a chinese quad wheel cheap$$ .Find the right length axle and add disc and spacers and little creativity and you have a pretty cheap front end.
    ATC Triples landed in oz $60-100.Atc Front wheel around 200-300 landed etc
    980 is crazy

    Anyone ever tried a Carlisle AT489 tire up front on the bw200?
    I took sixpeppers advice & went with the kenda K535 knarly on the back.

    I have one on my BW200. The 25x8-12 isn't as wide as many other tires called 25x8-12. However, the tread works pretty well on the bike.

    Does the 489 25" fit the rear ok (anyone)? I was looking at the trail wolf, http://www.ebay.com.au/itm/141270662692
    (or something heavier lugged than the Duro's) for rock and trail. Nice looking boots!

    Have you considered the 24x11-10 AT489 using the DMO adapter?

    Thanks, I have. I'd like too... just baulk at the extra expense. Nothings ever a bargain on this side of the planet, most often involves post$$ eg even the duro 25" cheapest I could find is around $130au/$120us. I do want Bill's swingarm mod but baulk at the wheel adapter mainly for the extra expense. And sourcing the right rim. Tried AMS swamp fox but it was square and too tight.
