I have had my teryx a couple years now its a 2011 fi model. It recenly quit starting to to the intake valves being too tight. I read some stuff about it, is it as bad as everyone says? Some on line say tear it down and replace valves. Is it that bad or ?

valve trouble

all I can tell u is once I started adjusting mine, it was all the time until no adjustment was left. ive used kibble white and dragonfire racing and it didn't matter. but I never had the valve seats recut which could have been the problem.

I have a 2008 750 ( new to me a month ago) that was running and idling poorly. It was through this forum that I came to the conclusion i should check the valves. Well it turned out that the valves were exceptionally tight (cold engine) and once I set them properly it starts, idles and revs up nicely....but....I can really hear valve noise now. I have triple checked the clearances (cold engine) according to the manual (.5 front .8 rear) and they are always spot on. I am wondering if I have to wait a bit for it to set in or should I forego any further operations until I replace them as mentioned above? Will the noise subside once they settle in? The snow is getting deep here now so changing out the valves would be a good winter project for me, just don't want to do any unnecessary work if I can help it. It's not my intent to hijack this thread, but it think any reply would be relevant to the OP's concerns.

My 2008 is one of the first Dasa 840's and I have only had to adjust the valves a few times. They are always pretty close to specs.

Yeah they are real noisy when set properly from all I have heard on this set them wide as the tolerance can be so it will be noisy as they tighten back up it will quiet down some I guess, just hope mine stay noisy for a while.
