Yes the rod was too short

I found a better quality rod end and threaded a rod the rod ends have a deep thread for adjustment

the seat is from my Sportster the front fits just under the tank and a wing nut hold the seat tap

I may eventually get a early big tank and stock seat or /7 police solo called a bread loaf seat depends what I can find....

Thanks, I thought as much on the linkage. The seat did look vaguely familiar, I have been going on e-bay looking at solo seats that may work on the R90/6 series. Most of what I have seen are for Harleys, which is OK, but I am having a problem seeing how they would work on my bike. Most look like I would have to use the old seat pan as a base, so I still had access to the tool box. This outfit in Germany seems to have decent prices, may get a seat from them. Here is your solo model.

To add to/consolidate what has been said...

It is perfectly possible to fit the 'Kinematic' linkage (which is what you're referring to) to the earlier models. In fact, what you are looking at on Ebay appears to be a retrofit kit as supplied by BMW for this purpose (still available I think). To be pedantic, it has been further modified so that the original 'bent wire' linkage is replaced by the later ball joint type.

If you want to go down this route, you have to get the retrofit kit as the stock footpegs used on the later (/7) models are different and won't easily fit on the earlier models.

As far as the position goes, It is correct that the footpeg (and, therefore, the foot) remains in the same place but the kinematic linkage requires less movement and by adjusting the later linkage, you can lower the lever a bit which might be enough to solve your problem without butchering the pegs. Worth a try.... depends if you want to go for the 'rearset' look or prefer to stick with the BMW position.

Regards

Rob

I was leaning toward the rear set idea with out major cost with a proven comfort position idea that works

I like mine as the kicker can still be used, although I never use it for starts

Even though Tim one will have to move the heal to reach the shifter as soon as I can I'll repost with my shifter
