i had a local shop do a dynotune and a hotcam in my xr650l..seems to have a bit more power..but i looked at the cam and the paperwork and it seems to no longer have an auto decompression!! now it almost wont start when cold...can i add a manual decompression? or can i add an auto decompression to a hotcam?...(doubt that). thanks guys for the help..i have out chasing "pink snapper" instead of riding)..i am back though.lol.
