I use Mobil 1 4t 10-40, but I'm not racing, and no extreme riding really, just cruising, I quit the speeding ticket habit in like 1985, well slowed it down a lot after having 11 of 12 points on my license, it was definitely time to quit the habit, so my bike doesn't really feel to, to hot, yeah in the starboard side she's a little hot at the lights. But runs good the rest of the time, think it's more important to keep it clean, mine only has about 1,000 miles on the oil change but it's crystal clear. The best treatment you can do to your bike give it clean synthetic recommended fluids, I can see mine smile when I twist the throttle, plus I'm 60 this year so my extremes are all but behind me, I'd like to get it on a Dyno tune and see what she will do in a 1/4, maybe bust my buddies chops a little, he's been bragging he just got into the high 10's, and I was joking around with an old pickup with an exhaust and first time I really got on 2nd gear and the beast started to roar, it was great, only took it into 2nd and we both backed off. The fastest I've had it so far was about 100 mph, felt pretty smooth too, especially for a bike with 46,000 on it, 14 year's old. I tell you I looked at the new one tfc sure I'd love to have one of those and 1 of those over there and a few of these, but I have to eat too so



but what I'm trying to say, not much plastic on the 08, and forget about the jap bike's, even the aluminum is like plastic, I wore my 80 kz 1000 out in 3 year's with I don't know about 25,000 on it, it did bad death wobbles around 80 around the Twisties, talk about scary, I'm a big guy and almost thought it was going to wobble the bar's out of my hands scary.
I knew it was just swingarm bushings and races and steering head bearings and races were shot, I beat the p**s out of that thing for 3 years, and bought it brand new.
But anywho back to the post, I probably should have used 20-50 on the kz, but the engine was still strong when I got rid of it, never had any problems besides the wobble after 3 year's,
Unless you are always over the speed limit by a lot or you live in Germany and travel the Autobahn daily or any places like that, The 4t full synthetic 10-40 Castrol or Mobil 1, I hear guys use Amsoil, V-Twin, I think the local shop has the one of the last 2 I don't know anything about the others should be good, I'm old school and believe in Mobil 1 product's just preference guys, don't attack me all day once!!! Oh and I hear some guys say they get 10,000 miles out of an oil change

yeah I would advise against that, if you're avg. Hard on it 3,500 miles, and if you baby the you know what out of it maybe 7,500, in a perfect environment yeah 10,000 miles, now add a little dirt that can somehow get in, and I don't care how tight you're engine is , you will always have blowback through your ring's, that's carbon in your oil floating around like compound creating more blowback and clearances. I never got more than I'd say 5,000 a year and it's suggested to empty the oil and add new if you put it up for a while, like the winter because read acid's in motor oil from combustion gases in oil, what is the service interval, some are every 6 months regardless of miles, and I'm pretty sure it's at least every year. An oil change is cheap compared to a rebuild, especially if you don't know much about a bike and have to use the dealership rates.
Hey what's the top speed limit up there, I've never been there, guess there's some nice Twisties, I've got to put that on the bucket list



Keep it upright and between the lines and away from hard objects
