It shouldn't hurt it at all. I have run 87 in everything that I have ever owned. I wouldn't drain the tank. Just run it out and then fill it back up with 93.is it bad to run 87 gas instead of 93 in a 400ex? What kind of damage could it do? i accidently put 87 in it, should i drain the tank?
Ok thanks. ran into a little problem, the guy that ordered my chain said the stock chain was 92 link, so thats what he ordered. i took the chain off and counted the links and its 96, so my question is would a 92 link fit? the 96 was streched or too loose one. my 400ex is a 2002.
If you still have the stock sprockets, the 92 link might fit, but my repair manual calls for a 94 link chain. But yes, if it isn't long enough just add links until it does fit.I checked the sprockets and they are stock size 15 tooth front and 38 tooth rear. Idk what to do i havent opened the 92 link chain to check if it would fit because i dont know if the shop will take it back opened. could i just add a couple of links from my old chain to the new one to make it fit?
