Re swapping forks over, there's quite a bit of info in the various threads on the topic. Here's an example, with tons of good data.

I liked Jonno's solution best for simplicity & cost. Ppl seem very focussed on KTM forks. Jonno's solution was to use the Yamaha triples, press out the old stem, & get that remade to length.

Going to pick the YZ up sunday morning. I was surprised to be the only bid. Robbie just ph'd. Robbie has also got a copy of the YZ manual, including fork servicing, which is great given the interweb doesn't seem to have too much info.

I think this purchase should work out very well. Expect to recover the purchase costs by breaking the YZ & selling off the bits I don't want.

Mark, you are welcome to first dibs of any (non front end) parts. Keep in mind I need to sell stuff to justify the purchase.

I suspect that it'll take a while to get everthing sorted for the new forks. I didn't really expect to be holding these for another 12 mths or so. In the interim I need to do a few rides.

Once the new forks are on, I will sell the entire BMW front end.

I've basically given up on the concept of being able to convert it back to original. Given the mileage I don't think its ever going to have that sort of appeal...

Did you read that thread on GSers
http://www.ukgser.com/forums/showthread.php?t=247228

The guy is rebuilding a G/S. Richie Moores doing the work so it'll be big bikkies however the owners pretty honest & says if he doesn't like it he'll just sell it on - basically a new airhead (loking pretty fking cool). I reckon since Moorespeed is so popular he'll have a few people wanting to buy it.

I'm checking out all my customers sheds hoping to find one that's been sitting for a few years & is taking up space.

Mate, I'm all over that one, this one, & this one. All very inspiring. But I am not going monolever (at least for now). I made that decision when I bought the Ohlins. At that time I thought we had a solution to the Paralever pivot bearings & U-joints. Doesn't sound as if that's necessarily the case now.

Let me know what you want, & I'll hold it for you, if I can't sell it now....

Picked up the YZ today. Its little rougher than I thought from the TM pictures, but I suspect that all the good bits are on Robbie's bike. Stripped down to component parts quickly, & making an appearance on a TM site nr you....

The valuable bits are still on the rolling frame - the rear wheel, shock, suspension linkages (provided the bearings are good), rear brake etc. The bars are Protaper (Carmichael bend) fat bars, with a nice converter.



First steps are to check the forks for twist (I need to investigate further), get new seals (the left fork is leaking badly), service the forks, & to get the stem machined. I can't see me doing that until sometime in the New Year.

Fortunately Robbie has provided a YZ service manual which includes a fairly comprehensive section on the forks.

Robbie has had his forks out & tuned them himself from MX hard to Trail plush, so should be doable. Worst case I'll pack them off to Robert Taylor.

I'll probably limit the travel on the forks to more of less standard BMW travel, not run with 300mm. But I'll try the forks out before I start to modify too much.

Measured up the YZ footpegs. That could work. Ideally I'd use Honda footpegs because they use similar pivots, but seeing as I've got these one already...The YZ pivot bolts are 10mm rather than the BMW 8mm, and I would need to shave a little off the rear of the YZ footpeg male pivot point, but all looks very doable. I'd also have to hog the frames holes out to 10mm. No going back from that one. Overall, drops the peg slightly, & gives a wider platform for standing. First photo std BMW, 2nd std YZ, third an unholy trial fit on BMW.

Looking good bro. I have been following those threads too. The steering head chop is pretty major. I have to laugh how many guys suddenly get upset & offended that someone other than HPN are modifying frames etc -

I looked up the 'basic' last nite & what a great concept - get all the surplus bits & make up a bike with them -classic. My mate may still have those yz forks if yours are rooted.

Is that rear shock the same as the GS???

Kokopelli (Alex) has got one.



The basic is a paralever, without all the fairing rubbish, and got a G/S style subframe, and the older style instrument / light set up. I think they also got the sports (White Power) suspension. Unfortunately BMW doesn't have stocks of that suspension now. The Kalahari was the basic with a G/S PD tank.

Looking at that photo, you can really see the difference between 300mm of suspension travel & the BMWs 200 or so....(albeit that the KTM is on its stand).

If he's the bloke in Nelson advertising via TM for '03 YZ250 forks, tell him he's an idiot. I would have bought those Labour Weekend if he had answered my queries. As it stands (always assuming these forks are okay) I've done muich better now...

Yeah, me too. I'm still half counting on that one.

What about using a sleeve inside the YZ peg's hole?

Thought about it. It's easier to bore out the frame holes than find some sleeves. There's enough meat in the frame pivot to accomodate the larger holes.

I looked at replacing the klr forks with wr/yz forks (the suspension on my wr is so plush and compliant but doesn't get upset by big hits either - its light years ahead of any other bike I've ridden) but I couldn't see how I could do it without blowing about 2k in the process

forks 600
service 300
springs 300
engineering 400
plus plus plus....$$$

it started to seem a little excessive for a klr

I realize that's just chicken feed for someone with airheaditus....

Danger on kiwibiker did a great job servicing/modding the forks on my sons sx250 at a very reasonable price.

Try some sleeves from a 10mm dynabolt.

They should work!

Perfect Airtech (cheap) solution. I can also use the dynabolt sleeves in the HPN tank, where it bolts to the frame. Welcome to the build team...

Unfortunately those pegs are presenting other fit issues. ...

The YZ mounts are wider than those on the BMW. I thought that I could grind down the spacers to achieve a fit. However it turns out the main limiting issue is (the width of) the springs. So maybe they won't be a solution after all.

Spring issues aside, I would also need to run a strip of weld on the frame, to make them sit in the right position. I can't weld the pegs themselves because they are some type of super tough alloy. They make pretty (white) sparks on the grinder though.

Pity, because I really like them otherwise.

welding

Try using stainless rods or tig welding with s/s rods.
Give me a bell and I can do them in work for you. Cheers, Barrie W
