My old high school buddy built a 1200cc ironhead XL with S&S stroker flywheels, Andrews cams etc. It was a trifle hard to kickstart. So he CCed the heads/pistons etc to work out the compression ratio. It was about 14 : 1. It seems the pistons he got were meant for alky or nitro. He paid $50 for the brand new flywheels and about $100 for the pistons and three crank pins, legit, it was a closing down sale. Went fast. God knows how he started it. But he could. He was a light guy too, so go figure.When I started my build I was a young 23 year old street racer so this build was suppose to be a street legal full race bike at the time. So in consideration of weight EVERYTHING that didn't have to be on the bike wasn't on the bike. This included elimination of the weight of any electric or kick start parts and would be a bump start only bike. Some of you know the story of this bike how for 35 years I thought this motor was only 1032cc, 10:1cr. After a tear down of the motor after 35 years after never having been fired I realized it was actually 1327cc at 11:1cr and might not be the easiest bike to bump start for a 60 year old guy (not my mind, but the body is showing wear) in 95* Georgia. So I looked into a hand held starter because the spud for the engine was available for a very low price. I even got Alan Sputhe who I bought my heads from to send me a set of pressure relief valves to put in he heads to ease starting. But the mechanic who did the reassembly didn't have the confidence to do them so I'm glad he passed on the job. But now I don't want to tear the top end down again until this freaking thing runs and I put a season on or how ever much time it takes for me to determine it needs to be done. In the mean time I need something to turn the motor over enough to fire it up before a few other things on the bike can be completed.Then I will need something that can be used at the starting line for LSR runs and trackside at RR tracks. and ready for use for DD. I just don't know how hard bump starting will be when I leave my destination without a starter. The hand held was portable enough to have fit in a backpack if need be with the motorcycle battery driving it, but that battery isn't enough torque to turn my motor or I have the wrong starter for this app. So thats why I need something like this.
Danger, is my business."
