How do all...just mulling this over....only had my 660ten for a month and overall well pleased...obviously ive been looking at the forum posts and there's quite a few similarities between the xt and fjr engines in terms of fuelling and throttle response...the CO mod and the throttle mod both of which ive come across on fjr forums (Don't judge it takes all sorts)..was wandering if the fuel mod and O2 mod would work?.....

anyway was just wondering
