hey guys i was thinking about going to croom on sunday. i just picked up a new bike a week ago. i got a 02 400ex i have no title but have a bill of sale. would i still be able to go? also i think someone took out the spark arrestor will this be a problem if so is there any way id be able to fix it so i could go? cause im not spend $75 on a spark arrestor i will just wait and buy a aftermarket tip for a little bit more
