    Alright ... we need an update.

    I bought a front fender for a DRZ400 ... and slapped it on. I also bought a 'Race Tech' rebuilt WP rear shock from a 1990 Husky 400cc bike. It was 17.5 inches ... so a bit longer, but adjustable. I got a screaming deal on it ... so I really don't have much invested in it ... so destroying it is not out of the question.

    We now have a new problem however ... the shock's eye's are ~7mm where the eye's for the BMW are made to be 15mm. The way I see it I have three choices:

    1. Drill out the shock's eyes. This would be a good one ... but I don't think the eye has 15mm of meat to drill. I could go ahead and do it, and then fit the 15mm barrel and wrap it in rubber and ghetto-tech the mounts. This is a very viable alternative.

    2. Drill out the shock to a standard size. Then turn the BMW mount bolt to that specific size. Don't like this because I am destroying the already nice and beefy mount to the shock ... and now we have two operations in order for this to work ... and inevitably this will prevent a future upgrade.

    3. Turn the BMW mount bolt to match the shock eye diameter. Don't like this because I'm drilling the already nice and beefy mount to the shock ... and really the same problems as above ...

    So I'm really leaning towards option 1. I'll wind up destroying the shock mount (on the shock) ... but it's the least of all the evils.

    Thoughts?

    I wouldnt ream the shock or the bike bolt or nothing... the bolt the shock takes will hold the shock, so I would just make a spacer to fit the mount. A Bushing, sir. :deal:evil

    Yeah, kind of. The mount holes on the frame are 15mm, and the shock eye is only 7mm. So he'd need a skinny bolt with bushings in the shock mounts.
    Hey Fred, my friend Odette saw you at HD and said "nice beemer". You smiled. She was in an Element.

    Yes it is.

    It *could* work if the 'new bushing' (Thanks Stage) fits inside the the shock's mount .... but I still think I'll be drillin'. But the other problem is finding a 15mm ID pipe with which to make a bushing, or ... heaven forbid .. buy one from BMW.

    Either way ... I have a total of $36 in the shock ... If I have to drill it ... so be it.

    And ... so wrong ... but so right :evil

    That's what I thought. :scratch

    Edit: Okay, I guess. I can't wait 'til ADVrider.com has a visualization app. Carry on.

    Dear Fred-

    Fred, you're my boy. I love and respect you a great deal. And I know I ride an ugly bike.

    But Fred? That's the ugliest goddamned bike I've ever seen. You'd better make that sucker work like no one's business to make up for the cacophonous riot of moto-vomit that I see in that photo. That thing looks like it's made out of WRONG.

    That being said... I'd ride the piss out of it.

    Oh, and I'd spend a few bucks to have the old shock mount cut off and a new WP-friendly mount welded on (mit gussets, of course).

    Your loudmouthed, short-tempered, socially retarded friend,

    bwg

    It's not THAT bad. We ride BMW's ... our general opinion of what is tasteful is already in question. Deny that. :lol3

    It also helps that I am a true left brainer. While I can identify colors ... they mean nothing to me. I see the structure, the forks, the suspension, how the frame works ... on a geometric level. Color? Yes. It has color (checking that off on the list).

    Now we're talkin ... and that is entirely the point. I have less than a grand in this bike ... as it sits. Right now. The point is really to see how much it actually takes to 'GS-ify' something and get me riding the trails!

    After it's all said and done ... I will have a working trail bike that I already know the in's-and-out's of ... and it won't have costed me my savings, first born, or left nut ...

    :D

    What about drilling the shock out to 10mm and bushing the mount from 15mm to 10mm?

    I wonder what a 10mm bolt will support in single shear mode?

    I like it. Haven't really been paying attention, is that a DR650 front end? Looks sharp. :thumb

    Can't you simply drill the shock's eye? Is there enough material? Is there already a bushing in the shock eye that's vulcanized to the shock?

    Can you take a close up pic of the shock eye?

    :dunno :scratch :ear

    The BMW bolt that attached the old shock to the frame mount is 15mm in diameter. There is something about this that tells me that I should leave this alone. I have never heard of one of these bolts snapping/shearing/etc ... While I like the idea ... I think I'd like to use that bolt.

    I could use a different bolt ... I'll have to look through the local hardware store's selection of metric bolts.

    Thanks Lornce .. it's a DRZ400 front end. As luck would have it the DR series all use a similar steer tube diameter. The bearings are for a DR650 ... A real 'mutt' solution.

    Drilling the shock's eye is the direction I'm leaning towards. Ther is definitely enough material on the shock ... just not in the bushing that I'm actually drilling. The solution might be that I simply drill a larger hole ... add a rubber tube, and use the bushing that came out of the BMW stock shock ...

    I'll post a pic in a minute ...

    Yep ... Next up ... some pegs that will be made from a damaged pair of /5 pegs on the shelf. And of course ... lengthening the center stand by 3 inches ...

    Just so you know, I've got, I think 2, R80ST shocks lying about that we could rob bushings out of. Also, I have a pair of stock R80G/S pegs somewhere. Could cut them up instead?? let me know if you want that shit and I'll leave it in the bin.:D

    Oh, ok....now you're too much of a bad ass to need a welding mask.... I'll leave the mask out too, just don't break it again....
