I have a 1992 sp which i have just recently bought.... everything seems ok but i'v noticed the front brakes chattering when i brake, more noticeable at moderate speed than high speed. head bearings seem fine, yoke pinch bolts all tight etc.... cant see anything obvious... next thing i'm going to check is the brake caliper pistons then the disk to see if all the floaty bits are free and if they're warped.... Anybody have any other suggestions? thanks
The nsr does not have floating discs but you can check that those buttons are tight . Either you have a ding in your disc or a problem with a loose part on the tripple clamp . The brakes are normally a strong point of the nsr.
Checked the front disk bobbins by putting a bolt through them and spinning them with some wd40 applied as suggested..... most were free enough but one or two had a little bit of dry white powder coming out at first.....but not exactly siezed solid. However, i tried it today and does seem better.... need a good run out to be sure. The whole bike seems quite harsh on the brakes and over rough surfaces... maybe its just me not being usd to a such a lightweight bike....? my others are quite softly sprung (CB1300, RD250)
Really enjoying the bike, its like i imagine a GP bike might feel
Can anybody tell me where to find the standard suspension settings for the SP..... damping, preload etc... so that i can set it back to standard and then adjust from there if necessary....have looked but can't find anything on the forum.... cheers.
Well, unless you're around 50kg dripping wet, and the suspension is in tip-top condition, it's unlikely standard JDM settings are going to be of much use!
Check the HRC recommended base settings on the main site and go from there, would be my suggestion.
Basically, you're probably going to find that most if it will need to be wound in pretty much to max until you get it all re-valved and re-sprung to suit your (western) weight. Great if someone's already done that, but most haven't.
The brakes shouldn't be at all grabby or judder -- the standard NSR setup is very good. I experienced some brake judder with a new tyre once, that hadn't been balanced correctly. Dead fork oil can be a contributing factor, as can the head bearings and old worn/contaminated brake pads. I did have some discs that were warped too, but they were RVF discs on an HRC front-end. I've never personally come across NSR discs that have warped. _________________ Andy.
