Not good. I'm considering another spring but I'm concerned about the damping as well. Ped seems to think it won't be an issue and BikerBill is happy w/ his shock so I'm a little confused as to how I should move forward.



that's not the real issue here...it's the linkage vs. linear movement; the latter requires a much stiffer spring. so sad, so sad.

Dude too funny! Great minds think alike!

I agree this thing stinks. I didn't need to measure because I could see it sink so far!

Think it is time to save my pennies and buy a better shock in a few months.

The good thing about goign with Ohlins is they are delivered to you with the correct spring weight, just for you. I believe Hyperpro does the same.

I was going to try this mod myself and went a little different direction. I went out on a limb and purchased from Yamaha the upper shock bushing (P/N 34L-22216-00-00 @ $8.40) and the lower collar (P/N 90387-1012B-00 @ $3.31)
The upper bushing in the R1 shock can be tapped out with a hammer and a socket and the lower collar is a simple slide out swap. I put my calipers on these items and found they were within .002 +/-. I recommend that you freeze the upper bushing for at least 24hrs prior to install as it will ease the installation, along with plenty of Never-Seize. As for the spring problem I was going to use a Race-Tech spring and swap it myself, now opting for an even stronger spring that they make. I'm not in any real hurry to do this as my set-up now is pretty good. I have the Race-Tech 1.0kg springs in the forks along with 15wt oil I had and extra set of spacers machined for me at work, cut them to 190mm and it gave me 25-27mm sag. Now when I crank on the stoppers the bike is rock solid. At 97mph it's like the bike is on a rail, turn in and high speed clover leafs are a blast now.

ok Kakashi so youre saying the r1 shock with the new bushing and collar worked out pretty well?

I got tied up with work and haven't gotten around to installing the shock, all I was attemping to do was to match as many parts to keep from doing any excess drilling or reaming of frame members and to keep the engineered connections as close to OEM as possible.
