Gixxer shock on a pregen (with pics)
There are probably as many different ways to do this project as there are people that have done it, here's how I did it.
to start with the stock shock is 12.5" c to c as you can see I've added a preload spacer about 3/4" thick under the stock spring DSCF0025.jpg GSX-R shock is also 12.5" c to c (might be 1/16" under) DSCF0026.jpg first I drilled out the eyelets to 15/32" to fit the stock Ninja bolts DSCF0001.jpg DSCF0002.jpg then we have to grind or file or machine the bottom clevis on the inside to fit the lower Ninja bushing from the suspension linkage DSCF0012.jpg I chose to use the grinder, be careful to not take out too much material or the aluminum clevis will bend or break when you tighten the lower linkage bolt DSCF0014.jpg DSCF0013.jpg the upper shock mount bracket interferes with the Gixxer shock where the front of the rear fender bolts up DSCF0015.jpg so away with it (the bracket), I used a sawzall with a metal cutting blade DSCF0016.jpg aaauh, fits much better DSCF0019.jpg now I cut the battery box off of the air box (I used a hand hacksaw)to move it up about an inch DSCF0005.jpg I used a couple of sheet rock screws to reattach the battery box DSCF0009.jpg then I cut the front of the rear fender DSCF0020.jpg to slide it under the battery box and reattach it with the 2 bolts in the bottom of the battery box DSCF0021.jpg have to drill a new hole in the overflow mounting tab as the rear fender gets relocated a little DSCF0023.jpg Put you plastics back on and your ready to go. Static height is 1/4" lower as the stock shock with the spacer did not sag under it's own weight, however the sag (with rider) ended up the same (about 1.25"). I used the stock Gixxer spring and all the stock Ninja linkage and bones. |

Great, simple write up. The pics are very helpful - especially the one that depicts where to grind for the lower shock mount spacer.
Did you need to shim your dog bones, to space them out a little bit? I have read where others state that they catch on the the shock spring.

Maybe they had a different year shock or something I can't even tell you for sure what year these are as my son just picked them up off ebay, but I've got 3 of them and they're all the same. |

2009 is the year of shocks. I think 08 was the same shock. 07 and older have the resevior up higher which runs more interference with mounting it. The 09's have the pretty blue anodizing on them. ha ha ha.

For whatever it's worth, Racetech's calculator breaks them down into '01-'03, '04-'05, and '06-'09. They're listed as having 450#, 425#, and 525# spring rates respectively. For comparison, the PreGen is 440# and the NewGen is 520#.
Just browsing some eBay pics, it looks like the '06-'07 ones have the reservoir sticking pretty much straight out, like the '08-'09 ones, as pictured in the first post. The '04-'05 and '01-'03 ones both have it angling up quite a bit.

Updating this DIY guide to simplify and make it even easier to do. For those wishing to install GSX-R shocks on Ninjette, there is no need to drill out upper shock bushing or your frame mounts. The 10mm bolt used for GSX-R shock is fine because it generates sufficient friction to hold bushing in between ears.
To use factory unmolested 12mm mounting ears and 10mm shock eyelet, you just need two sleeves like this. Might need to remove 1mm from width to not extend beyond width of mounting ears on frame. These fill up larger hole in frame mounting ears and allows simple bolt-on use of GSX-R 10mm bolt. Polaris # 5135275 - https://www.ebay.com/itm/302898035590 |

Would it also work if you were to grind down the bushing instead of the lower clevis?

Above instructions for top-mount of shock. Yes for bottom mount you can do:
1. narrow bushing on knuckle to width of shock clevis 2. use bushing-inside-of-bushing to fit shock clevis to factory bushing. Should be 12.7mm OD and 10mm ID. Just wide enough to tightly fit tightly inside clevis and factory bushing. This sleeve should fit inside factory bushing. Ream ID out to 10mm with length for tight fit on clevis on shock (slightly narrower than narrowed factory bushing so all clamping-pressure goes onto knuckle bushing). This sleeve radially locates and centre GSX-R 10mm bolt inside of factory knuckle bushing once that's been narrowed to fit inside shock clevis. Lateral location is provided by narrowed factory knuckle bushing. Once bolt is fitted with minimal play, tightening it locks everything in place. Rotation is done by factory bushing inside of knuckle. https://www.zoro.com/bunting-bearing...12/i/G4189586/ No hacking frame needed! Last futzed with by DannoXYZ; December 26th, 2019 at 10:02 PM. |

I need to take apart rear-suspension and confirm knuckle-bushing has enough extra-width to grind down to fit inside GSX-R's shock clevis... Perhaps this weekend...

To answer my own question - the answer is no, the uni trak is also too wide.
