I don't know what you mean by "performance". But is your suspension set up for you with the correct spring rates?
When was the last time your forks were serviced? If your rear shock is original, it is probably about done.
$$ is the issue at this point in time. I think id look into swapping out for a 750 before getting a power commander...
No my suspension, shock, forks have never been touched! My suspension could deffinitely use a hand considering im pretty tall, especially for a female rider...
Valve adjustment is going to be an at-home project for me and my dad... just need to look at the specs from a manual and get all the shims, and then possibly get some time on my hands to actually do it!! lol
But now im having another issue with my bike... may need to be replacing something other than what I mentioned previously.
Got the NGK Iridium spark plugs btw too im excited!
