Had a sad day today, my daughters beloved yamaha nytro er blew a timing chain??? Had to tow her 30 kilometers to the trailer. She is done sledding for the season. On a lighter note, my 900 ace gade towed her with no problem.This is her second yamaha and have had some problems with both, i guess they all have that at times. I dumped my beast of a yamaha early before the problems started??
