i have a horrible feeling.things are going to go bang
even at 64mm stroke they are thumpers and vibe quite a bit. a 120mm rod is a must, compare the two side by side on tickover and you ll see the differance.

I have the 64mm stroke crank with the 120mm rod by Mb developments and it still vibrates, numb fingers then arms if i keep it in the 4500 to 5500 rev range.
I know don't keep it there then but its the speed of the others i ride with 55/60 mph.
0 to 4000 and from 6000 to 8000 no problem silky smooth
Wasn't Jb down in southend going to do 65+mm cranks????

he refused to sell me one. said if it went wrong i would blame him and give him a bad name.
but he would build the top end for me with that crank. ££££££££££££££££££££££££££££
