I Googled "Motorcycle GP Highside". You're right. They still hi side. It's painful to watch. I'm not racing for the last hundredths of a second. I'm not carrying nearly that much speed. I guess anything could happen.
The (cam) Timing belts get changed at 15,000 miles. The 2 belts, if you get good ones, cost about $125. On the Monsters, and Streetfighters, you don't have to remove any body panels. The belt covers, are on the right side of the engine, held on by about 6 Allen/cap screws. Then, you loosen the idler, and swap the belts. Reset the tension, and put the covers back on. It looks simple. I've gotten to hate wrenching on things. I am fortunate to have a really good guy about an hour away. I may just let him do it.
Valves are to be done at 15,000 miles also. Honda 599s are supposed to be done at 16,000. Not that big of a difference.
Oil is supposed to be changed at 7,500. Honda says 8,000. Who waits that long to change oil?!
I like trying different things. I have good luck with my KTM 990 Super Duke. <That bike does take some cranking to get it started when it's cool/cold ambient temps. But it always, always started. Valves were checked on that thing at 20,000. All within spec. I've had that thing for almost 9 years, and finally did a mod to it. I had my guy put a Rottweiler intake, and a Dyno Tune. About $950. I should have done that years ago
The Hondas that I've kept for any lengt of time, I've spent hundred of dollars on exhaust, fueling, suspention, handlebar.... the list goes on. I put $180 (2) Radiator guard(s) on the Ducati, because one of them is right behind the front wheel. I'd won't NEED anything but a back tire for the next 6,000miles.
