I really like SnowTrax this season and find it very interesting & helpful.
My ride is a 2006 Yamaha Nytro. I like this machine, but the darting really bothers me.
I have tried just about everything I can think of and nothing seems to work, but after seeing your show on the weekend I’m going to give the Slim Jim SY4-6580 a try and hope maybe this will fix my problem.
Keep up the good work and remember snowmobilers everywhere are watching you.
Thanks for all the great information.
Thanks for your email!
You are not alone. Virtually all Yamaha 4-strokes come with the same outdated, dart prone ski. This trait is amplified by the reality of a heavy motor mounted high in the chassis – essentially a too-high centre of gravity.
You can mask the inside ski-lift and darting problem quite effectively with a set of Slim Jims – these things work exceptionally well and settle the front end of Yamaha’s immediately.
Steering effort will increase slightly but you will welcome it as the sled will respond in a more linear way to your inputs. This will allow you to keep the inside ski planted in turns.
A bonus with Slim Jims is their extra long life – they are super durable and will outlast regular carbides by a wide margin.
