I just bought a '86 with a Hindle 4 into 1 exhaust system on it and I was wondering if anybody else a set-up like that and what tuning it took if any to get the most outta it. It sounds great but I had to address a segment problem so I havn't been able to ride it and the guy I bought it from didn't know if the carbs had been tuned to the system or not. Thanks for any input. :ummm:
