If you think something is wrong with it let me know and i can adjust if we agree and re-post, then hopefully when i get time i'll draw up a better version on my autocad and include factory wire colours. Place your oil filter wrench on the oil filter and turn it counter-clock-wise until it is loose enough to turn by hand.

Insure that that it is going on correctly so you so not strip the threads on the oil pump. By running a bike for a few miles first, it puts all the oil back into the oil tank, therefore leaving a minimal amount in the case. Inspect brake pads and discs for wear.

I have a fully coloured wiring diagram that includes the variations on the charging system if attachments are permitted. So thanx for doing the job the way it should have been done by the people who made the money off it and sharing with us. Just saw a bloke in my office who is our electrical drafting guru. Pick up an A 1N-4004 which is available at Radio Shack very cheap as it will work fine. Well guys, just finished wiring it all up this weekend and everything works great.
