Posting this as a new thread, so apologies if it should have been tagged onto my previous.
Anyway,after reading replies regarding excessive movement to forks, I decided to strip and re-build. Replaced steering ball bearing race with taper roller, happy days there. There was definitely play in the fork bushes, and the oil was thin, grey, and smelly. When i put micrometer on bushes there was hardly any wear. Ordered new ones anyway, seals and dust wipers. The bike is ex police, (don't know if that is relevant?) and had progressive springs fitted, both were 485mm, so after the strip down and clean, they went back in. Decided to use 10w oil to stiffen up the rebound. All went well and off I popped for a test ride.
My findings.... I can't honestly say I notice any difference as yet. When braking quite hard the forks depress about 5" (tie wrap on sliders). When I go for an emergency stop and get the ABS to kick in the forks depress a further 1/2". Tie wrap slides to 3/4" below lower yoke, an overall travel of 5.5" which if I am not mistaken is about bottoming out????
I don't get any indication of it bottoming out, no bang or clunk, Should there be ? It doesn't even feel like it dives, but it must be?? Jacked front wheel up after 30 miles, and no movement in forks or head stock.
Having read all the threads, following fork rebuild, the overall consensus seems to be an improvement in handling, accelerating, cornering, braking etc,
It may be my inexperience or lack of knowledge of motorcycle cornering dynamics, but can't feel any noticeable difference since the fork refurbishment.
I would really appreciate your comments and thoughts.
Thanks Ian
