The 安いスリル CL360

[racing geek]

I got the FZR swingarm last night. ;D

Here is how the stock swingarm compares to FZR arm. The line in the ground is the center of the rear axle adjustment. The FZR and 360 both use a 17mm rear axle and the FZR axle width is basically the same so putting the stock wheel in this swingarm is literally a bolt in affair. The only problem is the pivot side of the arm. The 360 pivot bolt is 14mm and the FZR uses a 16mm pivot bolt. My plan is to open up the frame boses to 16mm so I can use the FZR pivot bolt.

With the dust caps even on the other side this is how much I'll have to narrow the FZR swingarm. The other end of the swingarms are almost the exact same width. I don't remember the exact measurement but I think the FZR arm might be a 1/4" wider.

Plenty of room for the tire since the FZR came with an 18" rear wheel. This photo was taken with the axle all the way forward.

Now I need to do some measuring and figure out how much I should take off of each side of the pivot point and how big of spacers I need so the chain and wheel line up right.

The front bearing spacer should be mailed out Monday. The plan is to have the swingarm fitted in the frame by the time the bearing spacer gets here. Then I can get everything lined up and hopefully put together a final list of spacers I need. I'm still not sure how I'm going to do the caliper bracket.

I finished narrowing the FZR swingarm pivot. Took it from 215mm to 200mm with a grinder and file. For the inquiring minds out there, I took 7.5mm off each side of the pivot. I used a cutoff wheel to bring it down to 202mm and a couple files to bring it to the final 200mm. I used the caliper to check the width at various points and it ranged from 199.98mm to 200.04mm and everything checks out with a square so I think I'm good to go.

I had to modify the passenger peg mounts in order for the swingarm to fit. The stopper for the rear brake lever is still in the way and prevents the swingarm from sagging much more then what you see in the picture but I want to leave that as is for now or at least until I figure out how I'm making the rear brake work.

I did some measuring before I narrowed the swingarm to see if it would contact the back of the motor and found that there should be 3mm of clearance. Once I get the bearing race narrowed and frame bosses bored out to 16mm I can see if I really do have 3mm or if I'll have to file away part of the engine casting. Oh, and the dust caps on the ends of the swingarm pivot clear the welds on the swingarm by a couple tenths of a millimeter. I'm glad that worked out but if it hadn't, I planned to file the covers so they are narrower and then use two O-rings for the seal.

I won't be using these shocks because they leak, but you can see that they sit a little too close together to line up with the FZR arm. I don't remember what the measurement was but I think it was something like 3/8". Should be easy enough to move the upper mounts out.

When I checked how the chain would line up I was surprised at how well the stock rear wheel spacers worked. With everything in place I used a laser pointed to check alignment and found things were pretty darn close. I should just have to play around with different thickness washers to get a perfect alignment. Since this chain is too short anyway, I'll break it and use that to verify alignment later today.

While I wait for the front wheel bearing spacer to show up I'll finish the tank mount and hopefully get the foot peg location finalized and fabricated. If I get that done and I'm still waiting, I guess I'll get the engine cleaned and looking pretty.


Since I'll be needing new sprockets and chain I've been thinking about going with a larger rear sprocket to give the bike a little more pep but more importantly to help the chain clear the swingarm. Anyone know of a website where I can cross reference sprocket bolt patterns with other bikes to find one that will work or if someone makes a larger sprocket for the 360?


Things I'm looking for:

• FZR swingarm pivot bolt and nut
• 41mm clipons
• enduro hand switches
• F2 speedo cable
• Sportster shocks (or some other kind of good looking long dual shocks)
