If so, anyone had theirs done recently ? How much did it cost for new seals, fresh fluid & re-gassed ? I can take it up to GRANT RACING at Knockhill Circuit, as they're K-TECH serviceing agents. Considering the shock is 15 years old, it scrubbed up nicely with a wash in clean white spirit. The rear hugger's done its job well over the years.   -------------- Just when I'm about to make ends meet, someone moves the ends !! Back to top

I think he said about 80 quid for seals, oil and gas. Might be worth replacing the spring too for something a bit heavier at the same time if you are more European than Japanese weight -------------- A garage overflowing with old stinkers...

I had a new spring fitted for my 'extra' weight and a racetech job. $A500 all up (240 sovs) but what a difference -------------- "The only thing worse than being talked about is not being talked about...." oscar Wilde Back to top

Thanks for the advice about the damper rod, Jools. I examined it yesterday with an ordinary X2 magnifier. Not a pit or score anywhere on the rod !       As I said at the top of the thread, it's in good nick for its age. Just needs new seals & a service.  ( See photos below ). As for a re-spring, I'm 12 & a half stone in jeans & T-shirt, & was able to set-up the rear suspension to my liking for the rough A & B roads in my area. The spring pre-load collars were about 1/3 to 1/2 way down the threads. According to Alex Red & Blue, it's a 91 Nm per mm spring as standard for R/RSs, so a stiffer spring might upset things on rough roads !! When I remember, would it be a worthwhile excersise, on a road bike, to put a 5 mm spacer between the top shock mount & the frame to raise the back-end ? Will it require a steering damper, or will it remain stable enough at speed not to need one ?? -------------- Just when I'm about to make ends meet, someone moves the ends !! Back to top

Warwickb Group: Members Posts: 1911 Joined: Sep. 2003 Posted: Feb. 03 2009,12:18 I use 5mm or more spacers on all of mine - road or track. Seems to sharpen up the steering with no ill effects at all. To an extent it depends on your handling preferences and how averse you are to the odd shimmy. Never had any slappers through speed alone. You might get the odd little shake when it kicks off a bump under heavy acceleration, or on the track under the conditions Jools describes. I've never really felt the need to fit a steering damper myself, but then I don't really like them if they are avoidable. It's easy enough to experiment with different ride heights using the simple washers technique - or you could thread the whole of the mount while it's out, add a lower nut and get even more subtle adjustment that way too? -------------- A garage overflowing with old stinkers...

Did you ever own an LC 2 Warwick ?, ( Mk 1 Power valve ). They were good at slapping / weaving in a straight line, from about 110 mph indicated, even on smooth roads !!  Crapped myself the first time it happened. It felt like it was using the whole width of the lane !! I was glad it had a big disc brake fitted at the back. ( The fork mounted "bikini" fairing was blamed in the bike mags at the time ). Anyhoo, thanks for the reply Gents. I'll find 5 mm worth of spacers / washers & put them on. I might as well while the back-end's off.   -------------- Just when I'm about to make ends meet, someone moves the ends !! Back to top

I Had a 4L1 250LC that used to weave like mad at anything above 80 when I first got it. Simply adding more preload at the rear cured it though. Stuck a 31K valve motor in it later of course. As you do... -------------- A garage overflowing with old stinkers... Back to top

When my fully 350'ied 4L1 started weaving, it was time to either replace the nylon main swing-arm pivot bushes, the worn back tyre, or both, if it was really bad !!   -------------- Just when I'm about to make ends meet, someone moves the ends !!

wullie3XV9 Wullie3XV9 Group: Members Posts: 293 Joined: June 2008 Posted: Feb. 28 2009,14:57 I collected my bog standard RS rear shock this morning from Bob Grant Racing, at Knockhill circuit, who serviced it.     ( They're K-Tech. service agents ). The bill was £169.00 pound all in for the strip & re-build, new seals, fresh fluid & re-gassed. -------------- Just when I'm about to make ends meet, someone moves the ends !! Back to top
