I have a 1995 Formula Z 583, it has a low end bog (below 2500rpms). What would cause something like this? I just got the sled about 2 weeks ago. It has around 2800 miles on it(now!) and is in very nice shape. I was told it could be something in the R.A.V.E. valves, is this possible?
low end bog is a good sign of dirty or pluggged air jets on your carbs, if you havent done so yet it would be a good idea to pull them off and have a look. if this sled is new to you, you dont know how the last guy treated it!! hope this helps.
