I think synthetic is a fine idea, after the break in is complete, that is. It's too slippery for break in.
I have a question about mine- I was ridin today (nice out, woohoo) and after a few miles I did a top speed check, hit 28.8. A vibration starts in at about 28. ? This is at 5300 rpm. (It's got a tall gear and a fat rider)
After a couple more miles, did it again and only hit 26.5, and the speed begins to sag off if you keep holding it wide open.
Would this be a sign of being too lean, too rich, or just not broken in yet?
Thanks for any responses in advance.
