Can someone give some directions on how to properly raise the fork tubes?

i need to raise the fork tubes up about a quarter in or so above the triple. long story and i'll explain after i get it done.

anyway, haven't done this in a long long time, so if someone here would be so kind to give me the step by step, that would be great. torque specs would be nice too if you hav'em.

quarter inch or so shouldn't affect handling much, right?

The top of my forks are currently flush (or just about) with the upper triple.

Thanks in advance.

A quarter of an inch will make a noticable difference. I hope you know what you are doing and have a steering damper.

Anyway, you need something to support the front of the bike. There is a jack point on the stock exhaust that will take a floor jack. When you have the front of the bike supported loosen the pinch bolts on the tripples and the clip-ons, not all the way, play with it a little 'til you can get the fork tubes to move. Let the jack down slowly to get the amount of fork tube above the tripple you are looking for. Make both tubes are the same and then tighten down the top tripple and clip-on to hold it. This is where it helps to have a piece of plate glass to check the fork tube alignment (3/8" plate glass 4"x10" or so). Now tighten the bottom a little. Once everything is the way it should be torque everything. Bottom tripple 22 ft/lbs, torque it a couple of times because the torque will change when you torque the other bolt. Top tripple 14.5 ft/lbs. Clip-on 18 ft/lbs.

when you say a noticeable difference...what do you mean? what should i be expecting?

yes, i have a damper.

1/4 inch or so appears to the max anyway the way it tapers the second time right under the clip ons. strange how it tapers in, and then tapers in again right under the clip ons.

Send a message via AIM to crispin
mine are a bit less than a 1/4 down.

No big deal.

We live in FL, no curves.

I do go to Jennings from time to time though. Don't want to hose myself and make it handle like crap. I'm slow enough up there as it is.

Why did you lower yours Cripsy?

Did you hollow out a portion of the fork tube for smuggling purposes :)

I raised mine 8mm and there is a considerable difference. Its much easier to drop into a turn now.

Yes if you go too far. This has an effect on the overall geometry of the bike, hence the weight transfer to the front end is more therefore the potential for a front end slide or pushing/loosing it is increased...........a 1/4"=6.3mm. If you measure the 1/4" including the cap (3mm) you should be fine otherwise its a noticable change to make @ one time.

While lowering the front will make the bike turn in quicker it will also make it more prone to head shake and tank slappers. According to someone who is much better at this than I am, it would probably be better to raise the rear to the max before you started lowering the front.
