hrc end cap, or open

[911]

so i haven't realy riden it yet, waiting to get it All set for mx, and was wondering if anyone is running ther hrc end cap or just opening it up. if you'r opening it what jet are u using? mine has a 162 main and think that might be lean if opened any more. the power seems prety insane compared to my 04. but was just wondering!!! And please don't tell me to just buy a slip on! if the stock mufler is a stiaight through i'm not spendin hundreds for the look of a pipe:rolleyes: + i still have yet to try on my 04 slip on to see if it can in some way be used:D

I took my hrc end cap and cut the little piece of pipe out of it and then tacked my spark arrester screen back to the end cap it is loud and suonds great

u didn't rejet?

I would run the HRC cap and rejet with a 175 main to keep it from running too lean. But don't run it without an end cap or some sort of restrictor. Exhausts are designed to have a certain amount of back pressure. Just my $0.02
