04 Rev 800 jetting question

[Van Epps]

I have an 04 Rev 800 with Race logic porting and a custom airbox that pretty much allows free flowing air intake.

I ride at elevations starting at 2500' and up to 5500'. My question is what would be a good starting jetting setup?

thanks for all input.

I would try the stock jetting to start with they are set a little rich to begin with. get some new plugs and do some testing.http://www.strappe.com/plugs.html

I have a 04 800x. I had the engine ported last year and the mechanic who
did the port work is setting them up with 450's. It runs well with these mains.

Thanks. Nice article on plug reading. How do you retard/advance timing?
