Octane rating & oil ?

[ringadingh]

Ive pretty well always used reguar 87 octane with no knocking, mind you I have a Power Commander installed as well.But I did disconnect the Power Commander once for a while and it didn't make a difference as far as knocking. Id try to run your bike on regular and see what happens. If it doesn't knock your all set. Using a fuel with a higher octane rating than neccessary for that motor doesn't make it run any better. Your just wasting your money every fillup.
As far as the oil goes Ive never used synthetic oil in the bike, I like Rotella T 15W40, it seems to do the job and I like the smooth shifting it provides. I can usually find it on sale around $15.00 a jug. I use it year round now. Nothing wrong with the synthetics but I just don't use them yet myself.
