1980 R100CS rebuild

[Looby]

Hello Airheads, 1st post to introduce myself. I have had a couple of airheads in the past, and ended up getting my mates unloved CS that has been stood for 4 years in a garage. It was running well when put away.

Having stripped it down to the frame to refurbish engine, gearbox and all cycle parts, I have just seen the cost of ATE caliper seal and piston kits, exchange fork stanchions etc. Due to the cost of refurbing these parts, has anyone put different forks/yokes front wheel etc on a road airhead? I have searched the forum, but can only find references to DR forks onto the GS. I think it would be cheaper, and ultimately better performance, if I could fit something else from an auction site. I don`t underestimate the work involved re the yokes and stem etc. but always loved a challenge, and have access to a large engineering workshop. I know the purists will not like the idea, and it is still only a thought of the way to go, but hey, why not?

I am only asking for any ideas, if anyone has done something similar, or knows someone who has.

Thanks, Looby

Are the caliper pistons really bad then?

It's a fairly common conversion from ATE to Brembo on these bikes.

When I rebuilt my mate's R80/7 we looked into the possibility but it was cheaper to refurbish the ATE set-up. Keep in mind that the donor Brembos, master cylinder, lines and forks might need as much spending on them as the ATEs you have at the moment and that's before you account for the cost of the parts for the conversion.

We decided that given the use the bike would get, the ATE brakes were good enough if properly maintained and adjusted. It's just that they need to be re-set each time the front wheel is disturbed for any reason and the under-tank master-cylinder is a bother to access.

If I was doing what you are, the deciding factor would be the intended use; if the bike is to be an everyday transport I'd do the conversion just because it would be easier to maintain with heavy use.

If its a sunny day outing bike, I wouldn't bother.

Thanks for the info gents. The pistons are corroded, and it was just a thought. For the use I would give it, Mike P is correct. Thanks again.

Jeez...£98 from Motorworks for the refurb kit and I thought £50 for the kit for the 4 pot Brembo on my 1100 was bad enough
