Hi. I recently purchased a B4 as a first bike. When I brought the bike to my work which is a automotive shop, it was parked there for about 2 days. (I know what a shame :( insurance in Ontario is a joke and they are asking way to much for insurance. If I wanted to be insured right now, It would cost $4200 a year but in August it will drop down to $1800. It is so expensive because I'm 21 and that's under high risk.... to many people bought Hayabusa's and killed themselves doing stupid things.......also one year of having a my licence). ANYWAYS away from the point again sorry. On the third day when I got to work I noticed a big puddle under my bike...... the rear shock gutted itself. Excellent my first bike and it already has its second problem, it needed a rear shock.(previous owner messed with the carbs and it would run sluggish 4-8k and then rip to redline with ease. got that fixed) but back to my main point.. I had to look for a rear shock. Since a shock from the dealer was ridiculously expensive I tried to find a alternative. I read tons of posts of replacement shocks. 91 gsxr 750, and sv 650(need to be modified). I decided to take a risk and buy a fairly new 2007 gsxr 600 shock it was only 30+20 shipping and it was really close in length (I will post the length tomorrow compared to the old one). it also has tons of adjustments if i ever need to fiddle around with dampening or rebound...
never mind ive been rambling to long BUT I got pictures of how it fits in the bike and what I had to do to get it to fit.Here's the bike itself before I started working on it. It had a hindle exhaust on it at the time which I shortened about 10cm(4 inch's) (I personally thought it was to long and I also had to repack it so it was a combo deal)
First I had to remove the old coolant reservoir since it is in the way of the new shock. It has a built in reservoir on the shock unlike the old 91 gsxr 750 with a separate reservoir from the body.
This is the shock on the bike with the old reservoir removed
The shock is a few mm longer then the stock shock so there was a little clearance issue between bottom shock mount and the wishbone body. I had to grind around 1-1.5mm of material off the center of the wishbone. This is a picture after I ground the wishbone with the shock in.
The gsxr shock is a little bit wider and wouldn't fit in without the washers. I have a picture with the shock installed already.
The next step was to make a new reservoir, since I couldn't reuse the old one(to big and bulky). The picture below is my reservoir in the bracket I made to hold the reservoir in place. It is bolted down with the battery tray(same bolt) and is supported on the other end by the frame. For a reservoir I used a 250mL(8.5 oz) battery acid constainer and I had to modify the cap to hold onto the overflow tube. I'm sure you can use something else for a reservoir but this is what i had available and it fit in perfectly. Make the reservoir was actually the most difficult part of the swap.
I found an excellent place to put my reservoir since it is easily visible and fit in perfectly
I thought I had images of the bike from afar after everything has been installed but I didn't take them X_X. I will take the pictures and post them tomorrow.
