Just wanted to get some opinions on spark plugs from all your guys on here. I've got an '81 LTD 750 and it has the stock model NGK's. On my last bike (2002 GSXR 600 ( bought new)) I used the stock plugs for a while then switched to the Hot NGK's and actually noticed a little better performance both in throttle response response and fuel mileage. What's your thoughts?
