i mostly ride mx but will be going to croom after xmas

Take that sumb1tch off!!!
but leave it on for croom

[rubicon500kid]

why leave it on for croom

[klutchbuster400]

they require spark arrestors.

if you jet it with the baffle off then its not going to run right when you put it on unless you change the jetting again

Just to let you know, they rarely check at croom to see if you have a spark arrestor.. But if you want to open up the YFZ a bit, take the baffle out.

All that is required at Croom is your money and a helmet.
