Riding a Ktm450exc and xr650, looking for good desert tires (anza borrego) and some street. I have a bike with motoz mountain hybrids on it and they are supposed to go down to low PSI with no problems. Any suggestions?

My names John T and I live in Carlsbad. Im a geologist and so I like to do a lot of local desert and mountain riding trips. Ive been riding since I was about 12 and had all sorts of bikes, mostly grew up on the XR's, but I had a KTM 250 2 stroke at one point. Now I have a 2012 xr650L thats been on a severe caloric limitation, and a 2007 KTM 450EXC.

Just got a 2007 KTM450exc. Im wondering on what I should be checking on it. It's been well maintained, not abused. Stats. It has 4000 miles, and about 200 hours, has a recluse clutch and a pipe but internals all original. I bought it from the original owner and he rode mellow single track and desert, older guy more cruising I think. He changed the oil (filter every 3x) and cleaned air filter after every weekend, had the valves checked 3 times, needed adjustment the first two times, the last time no. What should I be checking, in general given the hours/miles. Runs and idles good, the power is about right and it doesn't smoke or pop on deceleration.

i have a xr650l i got down to about 304 dry...makes a lot of difference.

Yea Id be down to take it out, and have it done right.

Oh one other thing about how much is it to rebuild these guys? Just the top, also top an bottom? Thanks you all are so helpful, I appreciate it.

I live in carlsbad. I can do a compression test but prefer the leak down, where's a good place to have it done?

One more question, how do i know when to rebuild the top end?

Thanks for all your suggestions, I really appreciate it. The motor runs perfect but seems noisy Ive heard the rfs motors are like that. Could the cam tensioner need attention. Also the guy was using Rotella synthetic 5w-40 I think, Ive used it in a bunch of different vehicles and it seems to work well, is the Motorex worth the extra money? Had the rotella in my xr650l, harley dana and vw bus!

Thanks, yes he was a good guy, he gave me 5 air filters he would keep prepped, to change after each ride...so Im really sure about the rest. The problem with the maintenance schedule in the manual is that the intervals are so short, like 20 hours rebuilds, Im not sure what to follow. The bike drives and run great, Im really stoked on it.
