    Put new plugs in

    I put new BPR7ES in my 95 750. How long does it take for new plugs too turn color?? It seems like its takin for ever. Its been 3.5 hours since i replaced the plugs an there just starting too get dark tan color.

    You should have used Bpr8es. As this is the plug that works the best with todays newer fuels. I find that in less than an hour of riding mine are showing color, so I am guessing yours is running way lean.

    WARNING!!!!!! Check length of BPR7ES against BPR8ES because if I remember correctly one is slightly longer than the other and if you put the longer ones in it could possibly hit the Piston! Best case it just closes the electrode gap, Worst case it could put a hole in your Piston! If they are the same then should be ok.

    My new plugs had a color after 2 chops performed. 15 mins riding, including warm up.

    The # indcates heat range. The plugs are the same length. Now the BRP VS the BR there is a difftrent length. As the BRP's are a projected plug and tend to be a hare longer, but there is plenty of clearance for them.
