I recently bought a 2018 CF500HO with low hours and miles. My first time taking it to real trails after riding for half the day it starting having an issue reaching top speed. The engine starts and idles fine and seems to rev fine. The machine accelerates but will not go above 11 mph in low and 18 mph in high (or close to those speeds-this was back in November).
This happened after I refilled and also went though a mud puddle (not that deep don’t think it even got to my shoes). When I brought it home I assumed it was bad gas so I switched it out and the same thing. I took off the clutch cover and it wasn’t muddy or anything. A little bit of dust but in my inexperienced opinion not much. I started it to see if the one way bearing was bad and all though the secondary was spinning I later learned that it will until the idle settles down so I warned it up and looked at it and the clutch did stop spinning when the rpm’s settled down.
I didn’t notice anything else that looked weird but after I washed it up and drove around trying to figure out what is wrong I did notice a rattling noise, the best way to describe it is similar to when a heat shield of a car is rattling just very faint and only on acceleration. Could be something in my compartments though but doubt it.
The only other details I have is the shifter needed adjusted since I got it. Very hard to switch gears and usually doesn’t light up the gear you’re in unless you get lucky. Lastly my friend also told me I could switch 4x4 on the fly so I did that but now learned it needs to be stopped. It wasn’t (and still isn’t) always engaging but it will occasionally.
Any ideas what I should check out for the limited top speed?
