After an afternoon of fun and hijinks (where the eff do all these vacuum hoses go?) we got the rejet kit into the carb and the air filter installed. The difference in power is subtle at in-town speeds, but I gotta hang on a little tighter when I accelerate. For anyone out there who is thinking of doing this upgrade on their GS500 and has aftermarket exhaust on it, I used the 128 jets and followed Dynojet’s instructions to the letter. Idle was unaffected, as was cold starting. I think I will have a lot of fun on my road trip tomorrow!
