Rickman race bike

Recommended Posts

Thought it would probably be easier to start a new thread for my rickman gs1000 race bike build,  the plan is to make it eligible to race with more than one club and still be competitive in ngrrc crmc csbk Germany and Belgium classic race at chimay

I Originally aquired the frame from Colin Chapman of tpe, he had had it a while but unfortunately some previous muppet had welded a gsx 750 engine in place in the frame

This took me a while to realise that the engine couldn't be taken out until I cut off the badly welded and bodged engine mounts but I had always wanted a rickman and this hiccup wasn't going to stop me

I am also fortunate to have wasp motorcycles located very me so after a couple of visits and chats they agreed to repair the frame and make a new braced swingarm and aligning the gsxr 18" rear wheel the engine has been tilted forward a little and the wheel base is about the same as a p&m so short as its a rickman the tubes are stuck together wit silica bronze brazing so had to be neat

I had debated getting the frame nickel colour powder coated which is a good match but still not quite the same wasp can help but have warned me that polishing the frame prior to replating is horrendous unless I fancy giving a polisher a lot of money to do it for me

I have been pulling together the engine and pull load some pictures separately

Had a bit more time to mess about with the rickman getting the front and rear suspension in was a good starting point 

And the tray for the electrics inner rear mudguard and battery box so made up a few cardboard templates and cut up some half hard alloy sheet I already had

An engineering friend and sam baker helped with machining up spacers for the efe front yokes and the caps to remove the anti dive unit internals sam also made a new spindle 

I had been accumulating parts for the build and had a set of twin pot front calipers which will comply with most racing regs miraculously they fit the original efe brake mounts

so thats my lucky brake everything else will need modifications to fit I'm sure

I don’t think you’ll be able to get the caliper to fully bite the disc with them bolted up like that.

Ask me how I know….

Grimeca (AP replica) calipers? Any reason you are sticking with EFE forks?

Yes the crmc for superbike 1 wheels 18inch and max 38mm forks plus the efe forks are longer so the bike sits 35mm higher than standard gs1000 so not grinding out the engine cases so easily

Quick trip over to ray debben performance to drop off some parts for the gs1000 race engine quite a few trick parts Including the nova straight cut primary gears and the katana rods,  kibblewhite shim under buckets with the usual new stuff like valves springs crank seals all the gearbox springs replaced etc 

Crank has been live balanced and aligned

This head i had race prep as a spare for the yoshi gs1000 I already compete with although this has the v & h d collars fitted

I will have to pull it apart again as kibblewhite titanium top collars need a different collet to the suzuki type i used and the head will need a surface skim as the compression is quite high on this engine build 

It will start on the button but I use a slave battery so I don't use too much battery power as no charging system is fitted

About the CR’s, great carbs.  5179 needles clip one position leaner than the middle.  58 pilots, 230 air jets, 138 mains, a turn and a half on the air screws.  Using the Keihin black plastic velocity stacks (with the grey lock rings) will noticeably improve response.  14mm float height, and use a push-pull throttle set up, once past 3/4 slide opening they have a tendency to hesitate in closing when relying only on the return spring.
