It seems that they are not holding air? The rims are not bented (I bought them used tho), not that I can see anyhow. When shinestreet mounted the yokos on the guy( who was very helpful and nice to shinestreet) told me that he had to put alot of weight on one of the rims, but there should not be any problems because it balenced fine. it seems that none are holding air well tho. what do you guys think it is?

 

They replaced the valves when you got the Yokos mounted?

 

Holy crap, thats IT!!!!!!!!!! they didnt replace the valves, but then again I never asked them too. How much does it cost get new valves on, would they have to unmount the tires again?

 

Well you could a water test where you dunk the wheels and tires in water and see where the bubbles come out. It is probly the valve stems if the guy who mounted the tires reused the old ones.

 

yeah, He might of thought I wanted to reuse them because they were mugen valve stems. Its not thier fault, I should of suppied the new ones.

 

PyR01-0347 has a good method, but to make it faster get a spray bottle of water and mix some soap in it and spray the areas where the leak might occur. You should see bubbles if there is a air leak.

Good luck.

 

if the one you have is a metal one you'll have to disassemle it then change the o-ring...very easy to do... if its a rubber valve stem those are cheap to buy and are easy to replace.

Are those the ones with a nut on the stem?
If so, just tighten them down a bit first and see if it helps.

 

where do you get the 0 rings???

 

i had a similar problem with one of my EVOs.the guy tightened one of the valve stems too much and cracked the o-ring.i dealt with the slow leak for about four years,but a few weeks ago i finally just broke the bead on the tire and took out the valave stem.i went to a local tire shop and they were able to match up the o-rings.i put a little loc-tite on the securing nut and tightend it until the o-ring bulged out just a little.re-seated the tire and it's fine now.you might also want to check that the valve core is properly tightened into the body-if they removed them to inflate the tire quicker they may not have fully tightened them when reinstalling them-this can also cause a slow leak.

To me it sounds like you got a bent rim. Cause when you're balancing you're balancing the weight of the wheel during rotation. Cause if your rim was a close to being perfect the rim would need little or no weight to make it even. Thats my theory.
