Widowmaker Journey to 200hp, no thats been done. 250hp !

Update, close to having an MRE built transmission, the hard work to get this build across the finish line is close to being done, fuel system complete, intake complete, electrical complete, I believe every part in those systems has been gone over now, thanks for following
 
now to measure 438 times drill once, Pingel stickered made in USA bag says japan, quality piece none the less, 1 step closer

Drilling into the bottom yoke making that the attachment point on the touring a no go, so after seeing Nevilles picture AGAIN duh, im attaching like the one in his picture, seems perfect fit and motion attached to fork tube. Thanks again Neville for sharing so others can go big also. :thumbsup: :cool: safety first

Kevin,
Between these two sheets, what changed on the bike that impacts airflow? I saw you changed from Ramair to the 4040s, and I suspect a retune. What did I miss that contributed to the torque gain?

Looking more closely, I'm wondering if you used Mufasa's timing table as the basis for the later graph? The curve has the same signature multiple-peak to it, but on the earlier graph it doesn't.

No i drilled the headers and installed bungs, tuned each cylinder and for timing we actually installed a knock type sensor, and that was the climb on numbers.

Thanks. I figured it was timing refinement that did most of the work. Reviewed some tune files and it was the only thing that made sense outside of a cam swap haha.

Good luck with the 250 setup, I'm sure Nev's head will flow very well!

With your block setup :sneaky: oh them cylinders you did seal! Nevilles head is really special. thanks man
