DEALER FOCUS we got some gains on our test bike. We took it for a ride on the road to check, and it went fantastically. We were all stunned with the end result. The test bike was my shop loan bike CD250U, so I lent it to some customers and they all came back wondering what had been done to it – the thing was a ripper! At this point I knew we were onto something. Next to get some treatment was Shane’s Quarter Midget one Saturday morning. We put it on the dyno and spent a couple of hours doing the jetting and ignition timing, which found around 3hp and really cleaned up the top end. This was great, but we really didn’t know what that would mean on the track – they were making around 21hp the way we built them. The boys went racing... and Cheese phoned me from Western Springs that night. We had won all three races and the feature race from half a lap back. The next week we ran up another four Quarter Midgets, and many more since. After a few years, we were getting bikes from all over NZ, some driven up, some trailered and some freighted. They were great times. LEARNING CURVE By the time I got the dyno I had been an A Grade motorcycle mechanic for over 15 years, but now I was learning so much more – it was so interesting to see how and why things worked. There were all the myths about “fit this, it will go faster”... yeah right! We could now modify a guy’s engine, and then prove that it was better. No seat of the pants subjective stuff, it was now clear to see with the before and after graphs. This dyno tool meant we could tailor the power a bike made with how the owner would ride it. It was about the overall package and rideability; there was no use having it pulling your arms off at the top end if you ride around town all day. I’d say my knowledge of the working of carbs really improved over that time. Upgrades to the dyno came along and I had a big one in 2005. I had paid $19,000 for the dyno, and the upgrade to Windows operating system, Eddy Current and air/fuel monitoring was another $22,000. It was a bit easier to swallow this time around because we knew there was business to be had. KIWI RIDER 25
