Testing one two three…..
A beautiful day in the neighborhood, so what better time to see what happens when the new nitro combination is subjected to a burnout test.
Getting the warm-up rig to be better behaved is a big plus, allowing us to warm the motor up on alcohol instead of nitro. This should make for a much improved oil dilution situation and bring the motor up to temperature much more quickly and evenly.
We had a bit of a kickback when the motor shut off on alcohol Thursday, so Fred took a little timing out of the motor below 3,000 rpm and that seemed to help things there.
The motor warmed up well, and the initial barrel valve (idle mixture/accelerator pump setting seemed to be pretty close, so after turning on the nitro things started to jump around. The cylinders balance was a bit off, temperature-wise, so turning the throttle rod balanced the cylinders and brought the idle up to 3,000 rpms, fortuitous in both respects.
Nick put on the rest of his gear and backed into the water. Bringing it up started the tire spinning and then it took off. There is another tone to the exhaust that adds an element of basso profundo that was not appreciated until the bike went past as now the exhaust pipes both discharge on the left. Bigger cams, more compression, bigger pipes, different ignition….it’s all good. Nick commented that the nitro platform definitely takes a bit of acclimatization, because of the throttle response. You had better be ready and pointed in the direction you want to go when you hit the throttle. The turbo gave a bit of warning, none such with this thing.
We were ultimately rewarded by the sound of car alarms going off in the neighborhood and at that point we realized our work here is done. Get it back inside before the cops show up.
Servicing the bike showed us the benefits of the new rings and the alcohol warmup, with the marked reduction of oil dilution by the nitro. The cams looked good and nothing fell off or out of the bike. All in all, a very nice day.
