resurecting crashed 87 with only 865 miles

Look at the stock cap. It's hard to see but see the set screw for the rebound adjuster?
i don't see provisions for it in the extended cap.
Perhaps it's as simple as drilling a recess or hole, in the extended cap so you could get the blade and shaft of a screwdriver down there to adjust the rebound adjustment?

Sorry mate, should have pointed out that pic is just an example.
There's plenty of extenders online that have access for suspension adjustment.

Klavdy is correct there are some out there (hollow tubes with male thread section at the bottom and female threads at the top) but I don't think they are for the USD set ups....  The cap design on USD forks does have more going on than the standard type - there are multiple adjustments available at the cap on USD forks.  There are thread in units for either the KAYABA or the SHOWA USD forks made by Graves Racing in southern California but they are expensive and they are only for that specific USD fork type (which ever it is was not correct for the R1 only for the GSXR sets).  In my mod post I had shown a pic of a set of red fork caps that threaded in and they were custom units made by a machinist for his own bike - he would not take my money to produce another set...  Found it:



I have not looked into it lately but I think they are now making thread in extender caps up to 3" long (for racers) designed to fit the newer big piston forks (also either Kayaba or Showa - can't recall).  The caps retain all the adjustment capabilities same as the stock units but are longer...  The later R1's from (2009 on I think) have the big piston forks and I was considering swapping my fork legs out for these newer units and then finding the thread in caps- none of which would be inexpensive nor easy to find....

I just can't get a grip on how to post pics

Anyway. I was going to use big piston(2009 and up GSXR) for this bike. But all the ones @ dealership that I looked at. The diameter decreases right above the lower clamp of the tripple. So you can't slide the fork down far enough. The cap for the big piston doesen't have the adjusters sticking out of it. It has holes to stick a screwdriver through it. So the cap extended would be simple to make. The only ones I've seen for racers are only 25 mm... if I remember right. I have the 2008 GSXR forks for this bike. So. If I get a day off.(worked 25 of the last 30 12/hr days)I'm going to take the cap off and see if I can remove the adjusters from it . To see how complicated it is.

Did you look into his suggestion of welding a tube onto the caps. And turning them down. I don't think You would have to get them exact. Like he said the upper triple clamp, is a clamp.

If you can take the USD forks to bits,why not extend rods/parts internally? Im sure a friend of mine did this a while back,but it involved a total fork strip down? The extenders on the top of the forks save the work. I definately know my pal shortened a set of ducati monster forks to fit a one off chopper. Im going to ask some questions to those that know,in other words my friend Garry.
