You know how it is, the SR has been behaving badly in its normal recalcitrant manner. You have worked yourself into a sweaty lather trying to kickstart it and don't want to try push starting it down the hill for fear that you will only have to push the horrid thing back up the hill to the shed when it still refuses to start.
After pondering this situation earlier this year I though that it was time to put one of the Honda stationary engine from the corner of the shed to good use. After a bit of calculation and design I came up with my design. On Sunday, I finally got the Mk I version of my starting rollers to what you see in the picture.

I still need to make up some covers, but they were complete enough to try and start a bike.
I fire up the engine, and got my XT's rear wheel up on the rollers, as it should be the easiest of my current crop of 500s to start with its worn out / low compression motor. Anyway, once up an rolling I found it quite a job to keep the bike in position, and the rear wheel seemed to be going much quicker than I anticipated. I descided to put the front wheel on the rollers and see how fast the speedo said the bike was going.
95kph!! Bugger, no wonder I was having trouble keeping it on the rollers.
I did a quick review of my calculations and found some fundamental flaws in my math. Hopefully I can correct the situation with a new set of pullies to slow the speed of the rollers down to a much slower speed and I won't have to do a full redesign.
Then there will be no more need to worry about getting all hot and bothered starting my racer again.
