2.02 intakes and I'm not a 100% on the exhaust. He set them up for a 600 S&S cam. He also cut the cylinders 40 thousands, punched them 10 over with new pistons, bored the G carb and installed a thunder jet

Good deal! It should be a real fire breather now!

Ex. valves are 1.615" Pistons + .030".

How much is it to bore the carb and thunderjet it? Not sure what my valve sizes are but I can find out, but dyno sheet says I'm pushing 152 hp out of a 124 bored to 128 running a 654 cam and a programmable thunder heart ignition. I know S&S built this motor in the speed shop right before they closed it down. They built the motor for a guy that backed out the deal, and I got a great offer on it and bought it when my 117 blew a few years ago. I ride a lot in the mountains of NC and live in the upstate of SC, and visit the beach areas when I can. And I usually foul out a spark plug or it runs a little rough when going to the beach or high elevations, I've been told a thunderjet would fix that. So just curious to know what you would charge for that and boring it out if that would help also.

Yeah, a thunderjet will probably fix that. An s&s carb has trouble spanning the entire rpm with just two jets, especially on a big motor. I would consider a 48mm mikuni. The Mikunis will feed any motor across the entire rpm range with no modification, and will have better throttle response in the low-mid range due to the variable venturi.

Back in the day, before fuel injection became the thing to have, re: RPO. These T-Jets were/are the BEST MOD for S&S carbs.

I'm glad to see you are still around and on this forum. You did some heads for me back in like 2010. I'm going to do another set as soon as I get this new carb set up going
