tires won't stay inflated

[rinconpete]

I put Mudlite xl's on factory Honda Rincon rims. The rears seem to be holding ok but the fronts need to be inflated just about every week. Pepboys did the mounting so I took the fronts back and they put a shirt load of bead seal on the rims but I still seem to have a problem with one of them. Their also are two small holes opposite of eachother on the rims, why are the  there, and could this be part of the problem. Can someone tell me how to fix the leaking down problem.

You must find out where the leak is. Take off the tires and submerge them in water, even the slowest leak will make bubbles under water.

Either do what Chillin said or take some purple drgreaser and spray them down. That stuff bubbles up better then water.

Sometimes your valve stems will leak.  put some soapy water on them and watch for bubbles.

Good idea. Also remove the valve stem cap and make sure the core is tight.

sometimes if you buy tires that are 2 ply,  they tend to leak alot.  not sure what ply your tires are.  I have holeshots mxr6's on my bike,   they leaked like a son of a pregnant dog around the bead till i had tire kingdom reseat them with bead seal.  i ride once or twice a month at croom,  everytime i ride i check them,  they still leak out about 2.5 lb's.  They dont go flat anymore though.  Its all in the ply of your tire or you have a hole.  soapy water works great.  A valve wrench is also a very handy tool to have around,  because they do need tightened every now and then.
