Heard that there might be issues with boosting the new 2016 Vipers motor damage is possible and Yamaha is telling dealers to stop for now any one have info on this and what Yamaha is doing about it
The later '16 got a different rotating assembly, suppose to fit engines across the whole line up(side by sides/watercraft). Yamaha doesn't sell a factory turbo sled, they do sell a bolt kit @ the dealer level. But its only 180hp, nothing more. MCX is not selling 270 kits for later '16 engines, they figured out the issue couple months ago. Why would Yamaha do anything about it? Engine will live @ 135hp all day long, as likely 99% of there sleds are sold in the east for trails. The aftermarket world is building stronger rods, but that's going to take awhile. There is 24 pages of info on TY4stroke.com about this if you want to read it.
