If any high level executive for Yamaha is reading this and you are really sick and tired of snowmobilers talking about Yamaha snowmobile weight, and you are really tired of being the number 4 mountain sled manufacturer then I have the solution for you!
I have a chassis design that would render the extra weight of your excellent 4 stroke motor irrelevant! It would not cost any more to manufacture than the current design nor would it entail any outrageous tooling costs, and no special material costs.
I am not joking, your excellent 4 stroke motor in my chassis would make a far more maneuverable mountain sled than anything currently on the market, you could literally jump from number 4 to number 1 in sales in 1 year! If you are interested PM me and we will make it happen.
