Just look on ebay for best prices. Lots to choose from.
Think of how stupid the average person is, then realise that half of them are more stupid than that.

M&P put a lot of their stock on ebay. Often post is cheaper than through their website. I bought JT front and rear sprockets in this way.

What plugs do you use and how do you run the bike? Up to 6000 rpm B7ES are ok, over 7000 rpm regularly B8ES are a must.
Needless to say, I use B99ES in the Earwig...... :shock: Only kidding, they are B98ES really :roll:
:wink:
