Winter Project: Race Shiver
The weather is turning cold and business has slowed enough that we here at AF1 Racing can turn our attention to a few side projects. One of those being a wrecked and totaled Shiver we picked up last summer for a song. While the Shiver may not make for an ideal race platform, that hasn’t stopped us from trying. And it’s been a completely budget build too: a free exhaust courtesy of Leo Vince, a smattering of leftover used parts, GSXR rearsets we found buried upstairs, and a bunch of after hours ingenuity.
The bike was totaled due to a broken frame tab for the obnoxiously long stock rearsets. We found a local master welder to re-attach the limb and then we were off and running. A one-off fully adjustable Penske race shock, adjustable Tuono forks, forged OZ’s from a Factory, Woodcraft clip-ons, SXV radial brake pump, UNI pod airfilters, a Mille PCIII Power Commander, help to complete the package and the list of modifications is growing daily.
The most interesting obstacle thus far is proving to be the tuning. Since the Shiver is ride-by-wire and has multiple throttle position sensors, it has taken some experimentation on which TPS is best to tap into for the Power Commander to get its information from. Full throttle is showing big gains but part and constant throttle settings are revealing the difficult nuances of tuning a fueling system that dynamically changes over time. Removing the O2 sensor from the equation is next and will hopefully bring us one step closer to the Shiver no longer fighting us on the dyno.
We expect the end results to be impressive and we’ll be sure to keep you posted. For now we just have to wrap up a few loose ends, like bodywork and getting the bike legal in a competitive class.
