Re: Fitting a Kick Start Shaft

The Li, Sx & GP Italian series 3 measure 67mm to the circlip groove. GP Indian measures 65mm to the circlip groove. So trying to fit an Indian shaft into an Italian casing requires the inside of the Kickstart boss trimmed down by 2mm so the shaft protrudes enough to fit a 1mm shim & the star...

Re: How close should the fins be to the cowling

On an RB250 that my mate Richard runs his AF flywheel was about 12mm away from the fan cowl & this ran at 260-280'c riding 80+mph when we closed the gap to 1mm the temp dropped by 30'c! It now very rarely goes over 230-240'c, running at 80+mph & this has 32bhp @ 8,800rpm. So it will pay to c...
