Hello all..new user..name is Jason..live in southeast florida. Long and short is I just picked up a 2011 outty max 800r. Did the normal services. My primary had broken weights..worn helix..dealer didnt have a new helix in stock so while I was waiting i ordered a cvtech primary. Got off ebay..explained to the guy what my bike is..it has 14in no limit rims and 30in mudda in laws. The tires are extremely heavy so he suggested the 3-4 oversized tires primary..just installed. Only removes the stroke limiter..tested movement b4 replacing belt box cover and was just tooling around the neighborhood breaking in a new belt. My engagement is 2600..shift out is 5500..also notice it's trying to shift from low to high..read up on that and I'll try removing shift linkage and see if it still does it. But my question is...unless I find someone willing to trade some 30in silverbacks straight up, I am stuck with the muddas for now. Dont get me wrong I love em, have them on a 500 vinson and long as it's in low they perform very well in the soup we ride in. Noticed in reverse with the 2600 stall I hit the rev limiter almost instantly. I messaged the guy I bought the primary from and he said that The spring was swapped to a 0951-1025 (400/1200 rate) vs. 0951-1017 (200/1600 rate) stock spring and that It uses the same 18g weights. What would be recommended for my ride. Only mods are snorkel extensions. Hmf muffler with quiet core(just installed the core) pc3 programer. Secondary is stock with a new 800 helix and a green/yellow spring..I did buy a stock secondary spring..any help would be greatly appreciated.
