How do you know when to adjust your valves... ive had my quad for almost a year now and havent had the valves adjusted how long do u guys wait to adjust your valves on your warriors or raptor 350's

 

nuthin??

 

i'd do it every other time I changed my oil.........
it isn't hard.....basic mechanics.....

 

how do ya know when to adjust them.... any sounds or power difference or anything like that??

 

Well, if you burn a valve seat you have gone too far between valve adjustments. I, myself, would stick to the manual for recommended intervals.

STARTING FAILURE/HARD STARTING
POOR IDLE SPEED PERFORMANCE
POOR MEDIUM AND HIGH-SPEED PERFORMANCE

 

i think mine needs adjusting.....is it hard to do on a raptor? 660........what u gotta take out?

 

You will need a service manual or CD. The work is easy if you know how to use a wrench and feeler gauges.

 

wow, great topic,,,,,,my buddy says nahhhhh,
look how good my quads run,,theyve never been.
i cant imagine doing that sounds hi tech, and very vital
to running right,.......i want to see how mine are

You will notice a loss in performance, probably something like a lean condition because the intake valves tighten up and dont let enough in. Mine started to backfire/sputter while deaccelerating. Very easy to adjust these. Just make sure you buy the right size feeler gauge, I screwed up and didnt take the paper telling me what the tolerances were to the tool store. Had to go back and buy the right one. Check out the Raptortranny website, they have a very good how to on there for the 660r but im sure with that and gathering some info on here you will be able to do it easily. By the way, mine runs like a champ once again!
