Gidday from wa

I am very happy to have found this valuable forum. Have just sold my 700raptor and decided to get back onto two wheels again. I love the dirt so it was a no brainier that an xt660r was in my sights. First mod was a 2 into 1 exhaust with headers, sump guard , pivot pegs, pro taper bars, sump guard , air filter and tyres. Need advice on O2 sensor and tuner. Looking forward to see other people's adventures... Cheers
