Over the course of the eight months he’s ridden the Kawasaki KX65 we have had zero issues. It starts up quickly, all the hardware is still intact, and the plastic that took a beating still looks decent. The only part we had to replace (after the BIG crash) was the stock handlebar. We switched to Pro Taper’s Micro mini bar, which is stronger and has less sweep to it than the stock bend. It seemed to fit Aden small stature better. I have done four transmission oil changes with Maxima’s MTL 80wt transmission fluid, replaced two clutch levers, and one brake lever. The only real performance modification was pouring in VP’s C50 race fuel. When Aden was first learning how to ride the Kawasaki two-stroke, the KX65 would load up on him (then would clean out and have an un-expecting hit to the powerband) on slower parts of the track. I tried changing the oil/fuel mixture several times, leaning out the pilot jet, but the problem still arose. VP C50 is a pre-mixed 50:1 unleaded/oxygenated race fuel that is sold in five-gallon pales, so I thought I would give it a go to see if it helped clean out the little two-stroke engine. After a couple tanks of the VP C50 fuel, I began to notice the Kawasaki KX65 with less oil seepage out the back of the silencer. Upon inspection of the spark plug, the plug had a nice brown look to it. Hearing Aden ripping around the track, I could tell the KX65 was crisper to the little guy’s throttle hand (without having that mid-range cleaned out hit). It is a little pricey compared to standard super unleaded fuel, but it makes the KX65 burn crisper and cleaner.
We are continuing to go out as a family on weekends and on the occasional after school trail ride. We will come back with another update in a coupe months and see how the top end looks after another 20 hours or so.
