Riding Yamaha Four Strokes
I've been riding sleds for in Colorado for a long time (40 years), and thought I knew how to ride - til I got a four stroke. Took 2 years and some coaching to figure it out. 4 strokes i've found need to be ridden more like a four wheeler, cause when you drop the throttle they stop. Throttle control is the key. I stayed with it because the reliability is unmatched, now you coundn't pay me enough to change. I ride an 06 Apex, stock track, stock suspension, MPI Stage 1, Simmons Series 2, ( these are excellent skis and should be your first upgrade), left hand throttle, under tunnel exhaust and high seat. I had very tall risers on it but took them off due to overcontrolling when sidehilling and went with 2" risers. The sled runs better every year - now has 4500 miles on it with zero problems, normal maintenance only. The power potential is spectacular - but the sled has to be set up by someone knowledgeable to make it manageable. That's my two cents worth - Good luck
