I can get hold of a NC30 rear shock recently rebuilt but before getting my hands dirty I want to know how to go about raising the rear of the bike a little.

Is the easiest way to get a spacer and put it under the shock linkage or to get some kind of spacer that is put between the spring (got to pry the spring apart a bit) and the bottom of the shock increasing preload so to speak? Does anyone know the rough dimensions of a would be spacer? I'm quite a newbie to this and haven't taken a look at the linkages and stuff yet so just asking in advance.

Many thanks.

An RVF shock linkage arm (the very bottom bit like a fork not the knuckle) will raise the rear by around 20-30mm

did that exact job just this week - works a treat

The easiest way on the vfr is to drill the shock linkage to make it shorter:

Agreed. Just don't go any further than 12 mm centre to centre or you'll have clearance issues. Works a treat.

That's great, thanks guys. Does anyone have a picture of the mod done and what the rear end looks like?

So from the original hole's center, I shouldn't go more than 12mm to the new holes center, is that right? I guess if i over shoot it and get clearance issues anyhow I could just put the preload ring down a bit? I think i will do this first thing tomorrow but just want to confirm that if I keep using my 18 inch wheel and go 10mm- 12mm shorter... it's not going to end up too high is it?

You don't have to weld the old hole up right? I don't have a welder so hope it's not critical eh.

Also- how far can i drop the forks up through the clamps? Will the wheel hit the radiator if they bottom out and the forks are dropped through a bit?

Rick Oliver recommends 8mm centre to centre in the thread link, I would go with what that man says! At 8mm you will have to fill/weld the original hole over. A garage could probably do this for next to no cost.

12mm will be too high. The exhaust will hit the linkages.

yep, the 8mm shorter one is close enough!

Thanks for the pics and stuff.

I don't get it though... on that picture the hole has been drilled in a different place to this one... http://www.400greybike.info/newforum/vi ... ide+height" onclick="window.open(this.href);return false;

Which one do I do?
