Or drill some rawbolts into floor so you can strap back down.

i have to say it was definitely a 2 man job, bike kept tipping forward when removing and refitting the fork's so roped in the gf to lean on the back of the bike while i torqued all the bolts up :P

OK, let us know how you get on.

I'm using 54mm spacers, air gap as standard, and my preload is about the same as yours. You might find there's a bit too much preload there with the longer spacer, I set it three turns in and had to back it off by 1 1/2 turns to get a more comfortable ride over drain covers and bumps. I'm going to re-measure static sag, change back to the standard spacer if I need to, and test ride again, and if it's still too hard for my liking, I'll try a 12.5w oil.

It may be an idea to meet up and have a short test ride of each other's bikes to compare notes. Maybe at Bassets pole or the Waterman when they get started.

only have 10w oil so will see how that goes to :)

will test it out if there to much preload i will make some smaller spacers

Well my bump absorption issue is probably the compression damping and not the pre-load, but I want to make sure sag/preload, etc is OK before changing the oil. Change too many things at once and you get in a muddle. I would definitely be interested to know how you get on with the 10w oil as I think 15w is too heavy.

We are the same weight, on the same bike with the same springs, but possibly different preferences about how we want it to feel.

What spring rate you got ralph? Too fast rebound can feel harsh too.

0.9kg/mm. You've just made me stand on the scales and I'm not happy!! 104 kilos (16st 4). F***ing Easter chocolate! :mad:

WOW that is all that i can say lol

ok its not all i can say, went on a quick ride through town centre down some dual carriageway and on some of the back roads also hammerd it over some speed bumps

general town riding is a lot smoother no jarring when hitting pot holes no load clunk ether and no harsh rebound (the oil i took out was like water)

dual carage way i was on is very unsmooth and the front seemed to cope very well and kept prety plush at XXXmph

speed bumps, well i wanted to see if i could bottom the forks out so hit some speed bumps at about 50mph (the big type) and the forks didn't bottom out my travel marker is about a inch lower than the bottom yoke befor with the old springs it was 1/4 and that was with just road riding

on the twistes the front seemed a lot more planted

i need to do some more open road riding but so far its a hell of a lot better

apart from one thing ...... the steering seems slow i think its because before the bike was sagging about 50mm under its own weight so i have gained about 25mm of front end height slowing the steering down so im going to pop the fork caps off at some point and fully compress the springs to see how much i can push the forks up through the tripples without having clearance problems

OK, sounds like I definitely need a lighter oil.
