Hello Guys,
Please help me if you can, I have a 98 FIII 600 with 4000 miles on it.I did my first 100 miles today, fairly hardpacked condition, about 18 degrees Farenheit, about 300-500 feet above sea level. I have 280 Main Jets in all 3 cylinders (290 is stock) and The TRA clickers are now on position 5 (4 is stock). Plugs look good in color (still slightly rich, dark brown color after 1/4 mile run a w.o.t.). The problem I have is when I hammer the throttle to wide open, it only goes up to about 7500 rpm, and the slowly reaches 8000 and goes no more. The max rpm setting according to my Doo factory manual says it should rev to 8500rpm. I was under the impression, when I hammer the throttle it should shoot up to 8500 rpm, and pretty much stay there. My raves are clean, carbs are clean, new OEM belt, all new bearings in sled pretty much including the one behind the secondary, clutches are aligned, clutches are clean and all stock (done this fall), new plugs....etc.... I suspect that my primary spring is weak, does this sound logical, or is it in the secondary?.....when I first got the sled, it would go over 8000rpm and go approximately 105 mph in good conditions (speedo) and now it only goes about 90 mph at 78-7900 rpm......any other suggestions, as this is my first clutching diagnosis and repair job. I do have the proper tools to do it if it is the spring, just want to make sure my theory is sound.......any other suggestions???
Thanks in advance folks......Ride on!!
