I have done a little more research on bikes using conventional show 41mm forks. For instance: Honda NSR250R 1989-1996 has very similar setup. And TYGA does work on them. I have found their Front fork overhaul on a MC28 NSR 250 SE at: http://tyga-performance.com/images/00psm/02tpfitman/08fitmantuning...

Hi Martin thanks for your reply. The front sag at 30mm with no additional preload is on the stiff side for a touring bike. The WP springs have been on the ST since the first service when new. They fixed chronic weight transfer on corner entry which gave the feeling the bike would run wide mid corner...

Hi Cadbury, thanks for the feedback. There certainly must be a way to separate the screw from the adjuster pushrod as there forkcaps with the screw but not the pushrod sold aftermarket and secondhand from other bikes. Its one of those things that a spare one would be useful to play with. I note you ...

The Standard Fork Upgrade Service Guide is an excellent starter to understand these forks. Can the fork rebound needle be removed from the core damper tube (preload/rebound)? How does the screw and needle work together? I may be able to get a better forkcap and damper core from other bikes but I do ...

Thanks Guys for your feedback, it has been surprising to me that the general consensus (elsewhere) is that oil viscosity is not a significant factor. There is a hell of a lot of oil being marketed with different weights (cSt). In conclusion I will be staying with the 5wt Maxima oil and just increasi...

Hi Martin,
thanks for your reply. I have tracked down the oil used previously (Maxima 5wt, 16.2 Cst)) so I can keep the kinematic viscosity consistent or about 10% lower.

Hi Tony, thanks for the reply. In response 1. Increasing the fork air gap only impacts the last third of the travel (softer). I am only using 115mm of the 150mm travel so hoping to increase travel and soften the last bit. SAG is at 30mm without additional preload. 2. The cartridge valves are tuned f...

Hi All, I am new to this forum but have followed it for awhile. I have my 1995 Honda ST1100 ABS/TCS fitted with re-valved VTR1000 fork cartridges and WP springs since 2015. I am reasonably happy with the result as it got rid of the hybrid damper rod/ cartridge set up of the OEM. The bike feels bette...
