I couldn't believe this. I had the valve clearance shimmed on my Manx, and I wasn't looking forward to bumping it up and down the road on a hot day. The bloke said I'll just start it on the stand by hand, and he put a rubber band around the throttle and put it in full advance to do it..!
If this will start with 10 to 1 compression, a side valve should start easily.
Have a look

Oh I don't know why you can't see it John..?
Ah Yes, the mudguard might cause a problem on most bikes.
Yes, that's it Rik. In 1st gear, wheel backwards until compression and one big swing, but I would have retarded the ignition a bit. He said he's locked his racing Manx mag at full advance and taken the lever off. I won't be doing that.
It still took me 3 attempts at bumping it when I got home, but the same principle applies. In 1st and backwards on compression, run like mad and dump the clutch. I didn't even sit on the bike. 1st gear spins the engine enough to give it a good chance. But be ready to pull the clutch in when it fires or the bike could be off down the road without you 
I must say that's not how I usually bump a bike. I usually use 2nd gear and run like mad

Hi Joe, My mate told me that speedway bikes were started like this. What surprised me was having it in full advance, you'd have to get your hand out the way quick in case it spat back.
Not something I'd seen before
