FJ Racer; Building Page 5

Something I knocked up was a support that acts just like a side stand. Because of the need to remove both centre and side stand when you step off the bike it difficult to hold the bike up and fit a paddock stand by onesself, so I fabricated a stand that simply located on the same location as the side stand and can be fitted whilst still sat on the bike.
Because of the removal of the footrest hangers I had the swing arm bolt reduced by 30 mm; this made it flush fitting to the bare frame.
To aid crash protection I fitted some R&G crash bungs. These are massive bits of plastic that are designed to fit the XJR and happen to fit the FJ perfectly. I was unhappy about using the Renntec engine crash bars because of ground clearance and weight (not a problem on the road!)
I set up the gearing to a standard FJ1100 gearing, 17t front and 41t rear. Fitted a DID racing chain which is lighter than the road ZVM chains and equally as strong.

Road Testing

 I road tested the bike on the road to set up the suspension and to bed the new piston and rings in. After 400 miles I placed it on the Dyno.

Now it’s a matter of putting the FJ Racer on the track in a race. The class it can run in is called ‘Forgotten Era’. This allows any road bike that was manufactured before 1989, mainly racing is Yamaha Exup and Suzuki GSXR1100/750’s.
I know it’s a tall order to put the FJ sports tourer up against them but then again it might embarrass a few, so I’ll let you know how I get on towards the end of the year.
