MK Indy GSXR Build Diary: Sprocket cover

As I am still waiting for driveshafts and various bolts, I cant really get on with the simple jobs I should be doing first.

Today I spent time painting the propshaft, trackrod extensions and trackrod ends. I just hammerite which seemed to take well to the rusty propshaft but not so well on the bare metal of the trackrod ends. I may have to redo these in the future.

I also sorted out the sprocket cover issue!! I managed to get a K6 sprocket cover off eBay for £21 which has the external clutch mechanism (like the K9) but it has the same fixings as the K1.

I drilled a pilot hole in the sprocket cover, in the centre of the sprocket adapter. Then using the pilar drill and an 86mm hole saw I cut out the hole for the propshaft. The sprocket adapter is about 88mm so I had a bit of metal to file away with a half round file which took a while but seems to have worked ok.

I test fit the adapter and cover and there is approximately 1mm of clearance on the right side – although close it shouldn’t be an issue as there should be no movement between the two pieces.
