Yup I may have to take a few days off when this crap breaks and go ride up to Ogunquit or somewhere North of me. Enjoy your ride I’m so jealous!

Happy to report, now well over 1000 miles on the 1275. Did a compression test (cold) and got 187 in the front, 190 in the rear. Sounds good to me. I know Hammer Dan says don’t use a Harbor Freight compression tester but it’s what I have so I used it. Dynatek DSPT-1 is still in and set on 28C and ran great today I did about 130 miles around cape cod and back. Oh and went ahead and ordered myself a Hammer Performance hoodie right after doing the compression test.
Peace folks hope everyone has a great weekend!

I've been putting off the 1275 kit for my Nightster. Reports like this are damaging to my willpower. Already running 7k limit, patriot, Hammer 560 cams and powervision and it hauls ass on anything it lines up with.

That’s a dam good set up already ,I bet it rips . And when you are ready for more then have Hammer Preformance do some head work for you and add the 1275 kit at the same time .

Spent a couple days riding up in Maine. Some wide open space I decided to give it some juice. Reached 100 mph very quickly with throttle open only about a 1/4 way. Does roll ons from 60-70 mph effortlessly. Has a lot more boogie than I suspect Ill ever need. Got over 2000 miles on the conversion kit now. Very very very happy with the parts I chose.
