Chris, you will be dissapointed to say the least !!

that engine will make 180-184 w/ all the pomp and pagentry that BSI has for it, right down to his reeds and his big farce carbs.. Thats also with the compression on kill.

I found them (3) to be at best 172-175 with pump compression , Realize bruces excuse is timing, ??

I've turned them up to the 16-17 degrees he wants and the power is still not there, plus the deto themselves to bits as timing in the midrange is 40 + advanced !!!!!!

stick with the companies who do NOT have glossy print catalogs,, learned that toomany years ago.

gus,
what is your experience with the zr900? I wanted to try the dyno that I bought from you on it.I was told the "BSI"1080 ran good?

Thats the reason I stopped helping people on this forum !
all the *, the cranks are junk the mouting makes them fall apart, YOU WILL RUIN THE STRAIN GAUGE ON THE ARM IN 5-8 TEST RUNS DUE TO EXCESSIVE HIGH FREQUENCY VIBRATION.
If you must dyno these pork chop cut cranks,,,,, secure the arm to the jackshaft with zip ties , this will keep it from wiggling. if the crank has .002 or more runout ,, DO NOT TEST IT << FIX IT . you will ruin your dyno instantly...
Had this happen on Grumpy's 990 , wrecked the strain and the in brake rpm pick up in one run !
NOW WHO PAYS !! ME OF COURSE.
stock 900's arre in the low 150's at 6900-7100
fwiw/ work with the people who can tune there own sleds very well,  the 800-900 based twin cats are dyno killers! 
triples will never hurt it period.
call if you have any questions Chris,
Gus

Thanks for the info! But what works on these motors?
