1250 kit and head work from Hammer Performance

[aibu1101]

I was going to ride about a month ago and found this.



So I looked a little more and found this.



and this...



When my exhaust strap broke I had about 32,000 mile on my bike. So I decided to rebuild the engine since I had to take it apart anyway. So I decided to go with a Hammer Performance 1250 kit with Smash head service.

And here is the finished product



I will post the dyno printout when I come up with $300 to get it Dyno-tuned. I spent most of my money on the engine rebuild.:D I did a tune with ECM spy, its running fine, but Im sure it could run better:D

have you ridden it yet? how much faster does it feel?

[aibu1101]

Since the rebuild I have put about 2,000 miles on it. The front end comes up accelerating out of corners:D. It does feel a lot faster than before, but that might be because I just love riding my Buell, now at 34,500 miles!! I think it was well worth the money!!

nice! I will be interested to see what the dyno sheets have to say.

I did a tune with ECM spy

Curious about what you did.

[aibu1101]

I flashed the race map onto the ECM and it ran a little rough. So I made some adjustments and its running fine now. I am just running a modified race map for now.

May I ask...you did remove all those sharp edges from the pistons (valve pockets) didn't you ?

Bad things for starting preignition.

Dude, can't wait to get back home and go riding with you again...although now I'll really have a hard time keeping up!!!

[aibu1101]

All taken care of by Dan at Hammer Performance. All the parts were ready to install out of the box.
