found a sled that i may seriously consider purchasing. i have been in the market for a low mileage sled for quite some time. 2002 mxz 700 with 1900 miles. asking 2k with trailer. only problem is it doesnt have reverse. how hard/expensive it to add. i know that it should have been equipted with electronic reverse so do i need to switch the hole chain case. i have found a good used manual reverse assembly on craigslist for 200 but id rather go electronic. any suggestions. thanks in advance.
