adjusting vaulves???

[CrazyCat420]

I have a new dvx 400 I am way beyound my initial break in period and I think that my vaulves are starting to get a bit noisy, has any one out there adjusted them there self??   How hard is it to get to them, and how hard is it to adjust them once you get there?  or would it be more worth my time to pay some one else to do it??  I am decant with a wrench to a point I just dont want to takle something that is going to end up being a huge pain in my but??  If any one who owns either of these clones or has ever messed with them could give me some info I would greatly appriciate it!  

Thanks,

Crazycat

not sure if the dvx is far off the 400ex concept but here is a link of how to adjust the valves on a 400ex

A DVX valve train is a shim style, way different than the 400ex style

Oh while yall are talking about valves, my suzuki 250 has around 2500 miles on it and was made in 2001 so it is about 5yrs old. I have never had the valves adjusted. Is that a bad thing and will that cause it to do wierd   all the time if they are left like that for a long time.

I am not an expert on valves but I do belive that exspecially after a break in period that it is in portain to re adjust the vaulves at this pint in the motor things settel in to place and I think that if you go to long then your valve clearance with the piston could be wrong which could cause some bad things to happen??  I think that the valve could actually become damaged or it could hurt your piston???  but I am not 100% sure of this I do know that you can tell when they are getting close to being out of adjustment because they will start ticking realy loud and gradually get worse, that is something that you might want to check out to maybe save you some costly repairs down the rode!

The technology with the shims is different than that of a rocker arm type valve system. There is no breake in period for the valves on a Z, KFX, DVX-400. The cam sits directly on top of the tappet, which sits on top of the shim, which sits on top of the valve stem. Should not need repair for a couple of years. The sound you hear is the tensioning device reaching its limit as the chain stretches. The timing chain will go beyond the limit of the tensioner rather quickly. best remedy is a manual tensioner and it will smooth it right out with hand tightening. The timing chains are a weak link as well as the tensioner. I have yet to find a good timing chain but the manual tensioner is a good start.

Hope that cleared it up,
