I'm going to work at an enduro this weekend. How far will my 01 CR 250 go on a stock tank assuming it is jetted properly, and I'm not on the pipe too often? I also have a IMS tank (not installed, came with the bike). How big is it? I think the first loop is 30 miles. Is there any chance I won't make it using the stock tank?
i have the same bike. jetted properly 40-45 no problem at race speeds. i have a 3 gallon clarke tank and have gone 52 miles at a woods harescramble so you should have no worries.
