Meeeaaaaxxxx!!!

Just get an aftermarket shock! Dew eet right. Dew eet tight.

I'm running the JRI shock. I love it.

(missing shock obviously)

mgentz · February 10th, 2014, 06:29 PM

I run a Penske triple. Smooth as butter.

shane liberty · February 10th, 2014, 06:32 PM

I ran a Penske on my Formula Twins bike. Loved that shock too. I did the JRI this time around because it's new and Cyclemall wanted to throw one on my bike. I'm going to be a guinea pig for a cartridge kit they're planning to build for Spears racing too. Can't wait to play around with that upgrade.

mgentz · February 10th, 2014, 06:46 PM

Nice. I wonder how it will compare to the andreani (sp?) Kit.

shane liberty · February 10th, 2014, 06:59 PM

I heard the andreani cartridges were a copy of the Ohlins kit but that could just be the rumor mill from Ohlins owners hating on another brand.

I'll let you know when it gets installed. I talked to Zoran at TWF and he said he could do a cartridge kit with GSXR internals for the Ninja for $700. He just needs a stock fork to take initial measurements so he can machine new fork caps. He hasn't done a kit for the Ninja yet but he's happy to do it

sharky nrk · February 10th, 2014, 07:34 PM

^^ $700 would be downright reasonable if they were decent.

mgentz · February 10th, 2014, 07:54 PM

Yes it would be.

shane liberty · February 11th, 2014, 09:45 AM

Well I ran Zoran's GSXR cartridge swap in my Formula Twins stock forks and won a championship with that setup so I can vouch for his ability to do some good tuning. He's an SV650 guru so I bet he could tweak a set of 250 forks no problem

shane liberty · February 11th, 2014, 01:51 PM

By the way, that deal with Zoran is open to anyone looking to take advantage. I'll post up about it.

Any updates?

r6boater · March 17th, 2014, 07:36 PM

In the off season, Draik got emulators and a gsxr rear shock set up by Jamie at

http://daughertymotorsports.com/

Draik was able to drop his lap times at Roebling Road from his best time last year by 8.4 seconds! We are very happy with what Jamie was able to do.

stimpee · March 18th, 2014, 05:39 PM

I think my son's crash at Roebling a week or so ago in turn 7 may have been avoidable with better rear suspension. I need to look into the gsxr shock as we are still running a completely stock setup.

I am guessing our sons were racing together so hope to meet you next time out!

Steve

mania · March 18th, 2014, 11:27 PM

For racers on a budget Ohlins has come out with a new shock
2 way but only roughly $300-$330

Part Number KA-110013

Some distributors may not have it yet as it came out of Ohlins
Asia division
I emailed Ohlins Euro/USA & Asia to verify it is really a Ohlin & they confirmed
yes it is & it is new

Ohlin quality so should be a decent shock

Was it with WERA? We will be at Nola on the 5-6 with WERA, you coming there? Look forward to meeting you and your son.

No it was the CCS event there 10 days ago. we have not run WERA yet. I think I need some more safety wire and a steering damper for that.

we are sticking with florida CCS this year but will be moving to Nashville next spring for my work and will probably start running the WERA races then.

I see, well I'm sure we will cross paths soon then. Draik will probably be on an SV next year though.

Draik got one of the ~$125 dampers off ebay and have been really happy with it.

You on facebook?

Kyle got on a bike for the first time at the end of July. We moved from karts to bikes. he is picking it up quickly but I am not going to move him up until I feel he has "mastered" the 250 and he develops some more experience and decision making skills.

I am on facebook as stephen andersen and kyle is kyle andersen. He also has a simple fan page too.

I will check out the steering damper and will look more into the gsxr shock. I think we at least need to do something on the rear of the bike.

I am sure we will cross paths once we get to TN. That is employer dependent right now though so will be a bit.

Very cool. Good plan for moving slowly. I'd recommend to do the emulators first, then rear shock. Send me an invite to his race page, I'll send you one for Draik's

gantt · August 6th, 2014, 04:18 AM

ok so as I was drilling out the steel sleeve in the rubber isolator the sleeve broke free. doesn't look like I can order just the rubber isolator to replace the broken one. how important is the isolator? can I put a steel spacer in its place? I have one that will fit perfectly. I don't want to stress any parts and possibly have a failure. any idea??

mgentz · August 6th, 2014, 09:58 AM

what part are you talking about?

gantt · August 6th, 2014, 12:35 PM

this one. I have a spacer in it now. I think it will be fine. nice and snug. the hole for the spacer is slightly off center. maybe 1/2 a mm or so. will make a new one soon.

fred smoot · August 6th, 2014, 04:33 PM

When I put on a GSXR 750 shock, I pressed the upper bushing out, And did not drill it to a larger ID. I put in a 16mm x 22mm piece of tygon tubing and a metal bushing that fit the diameter of the original upper mounting bolt. Nice press fit. All easily serviced if necessary. Drilling out the bushing leaves very little metal, and not much room, if any, for error.

Take a spring highlighted in green and match it to a shock that fits (highlighted in green) and you have yourself a good combo. All this can probably be found on ebay for way cheap. I got my two shock assemblies off ebay/craigslist for a grand total of $40. Not bad at all.

GREAT info!!!

for me weight 150 lbs no gear GXSR springs are too stiff , I believe I need 7.5 kg/mm or tops 8 kg/mm... now looking for spring rate on the ninja 300 rate for the spring..

once again great info

daverdfw · November 17th, 2015, 05:20 PM

bumping this from the dead, new Ninja 250 owner here, prepping the bike for track days next season. Looks like the GSXR600 shock is a great mod. Just trying to figure out all the spacer/bolts I need to do it. I am much heavier than most guys here, 220lb so the stock spring that comes on the 600 shock might be pretty close to perfect for me.

I will tell you now that the stock spring is too heavy. You at 220lbs and the bike at typically 340lbs +/- depending on whatever you delete or don't delete, etc. When i first did this mod I thought the same thing but I was 260lbs suited when I tried to make the damn bike move with my butt on the bike stripped down to like 320lbs. All the adjustments in the world made no difference. On went a 05/06 GSXR 1000 spring. That fixed it.

awesome info thanks! did you use the stock upper bolt and drill out the collar on the 600 shock? and did you use the nuts as spacers? seems there are a lot of people doing different things in this area. Thanks!

icbm · November 17th, 2015, 07:13 PM

Stock bolt and drilled out the upper. Used spacers from the HW store. Then made my own dog bones from steel straight brackets for something I don't recall for but came with holes that were close in size on one side so only had to drill the other sides.

I believe I made them 156mm in length.

I was looking at the dogbones online for like $20 or something.

As long as they give you the range you need.

daverdfw · November 17th, 2015, 07:46 PM

just ordered the 600 shock, the 1000 shock and the dog bones. Thanks for the advice!

I actually just took a gixxer shock off my bike with the last pair of dogbones Rexbo ever made... was going to sell the whole kit as a bolt on (shock, dogbones, spacers, even the linkage.) Thinking $50+shipping total.

WARNING. My preload adjuster on the spring is supppper chewed up. Long story short I took my gsxr shock to a shop for service and he lost it...so he bought me one from eBay and the adjuster was ****ed up. Would have to get a screwdriver on it and beat the hell out of it to adjust.

Can send pics if you like.

edit: then I read further and saw you bought your stuff already. Whoops!

Wish I could run that in CCS...great deal for the set up.

I need to keep stock dogbones though so- stock shock works for me

yeah thanks for the offer, I already pulled the trigger on the stuff. Just gotta figure out what spacers I need.

what drill bit did you use to drill out the upper? 15/32" or 31/64"

ROADandTRACK · November 27th, 2015, 06:26 PM

This is what we use for the top gsxr shock mount.
Just drill out the frame mount a little bigger and these fit right in so you can use a smaller Dia. bolt.

maybe this is a dumb question, whats the reason for doing those over drilling out the shock? would this affect down the road installing a different shock? Thanks!

ROADandTRACK · November 28th, 2015, 09:23 AM

You can use another size spacer for another shock.

Nothing wrong with drilling the shock except that I've seen the bushing get damaged several times and even if you get it drilled in the center the metal is very thin at that point. This is just the way we do it.

makes sense, where do you find those things? I found something similar at ace hardware for spacers. They are made of bronze. If i get to the point where I wanna race in CMRA ill have you guys rebuild it to be race legal. Right now I am trying to acquire everything just to get on the track and my budget is stretched thin (as is my wifes patience)

Just ride the bike stock and when you start to out ride it, then get upgrades.

only mods I am doing are a body, and suspension and tires. Everything else is going to wait until my skill level improves to where it matters for things like jets/exhaust etc. Just lots of really bumpy tracks here in TX so I want something suspension wise that will help me stay on the bike.
