Just wanted to let anyone know who is hesitant to go ahead with the valve adjustment. I just finished mine and it took about 1 hour or so (if that). it is very easy especially with the detailed instructions found on raptortranny.com. Get yourself a good set of feeler guages and go to it. My Raptor has about 18 hours on it and when I went to check the valve spacing they were all tight on the intake side and perfect on the exhaust side. After I started it up, let it warm up and I swear it sounded better as well as had crisper throttle resonse. Thanks Atv Connection.

 

Lucky you DIDN'T have to adust the exhaust valves, as they are a "*****" to get to! The intakes are easy, with the exhausts, it will try your patience.

 

yep,,,thats usually the case

good deal

Yeah exhaust valves aren't fun at all to adjust!

 

Good to see things turned out well.

 

boatcop sorry to jump in on your thread but could i just ask you, my rappy is stock, should i still adjust, sorry if its a silly question

 

you should check your valves on a regular basis (stock or not)

i check mine about every 20 hours of ride time
