Has anyone had problems with front tire going flat. I have had to replace my front tube twice with less than 300 miles between replacements seem to be tearing around the stem apparently the tube must be moving not sure what to do about it. Rode it the first time since breaking my collar bone yesterday. running 50 down the hi way suddenly tire instantly went flat was able to control it but wasn't a good feeling. need to get this issue figured out.
What air pressure are you at? I ran my 610 without rim locks for a while, but you have to keep the air pressure up, say around like 18 psi. If you go too low, it'll spin and rip the stem. Some more details about the failure mode would probably be helpful. There is no reason you should have frequent flats, I think I have had 1 flat in 5,000 miles of hard off-roading.
Don't use the nut on the outside of the rim on the valvestem. This way if you do spin, it won't rip the tube.
I agree --also another tip I learnt after 11 years of racing --take a small round file and just make the hole where the valve fits through the rim a little bigger --also helps when you have to replace the tube as the hole in the rim oxidizes and it gets sticky-- and jammed --
