what is stock lift and duration on the bandit and the gsxr1100? also still looking for somebody near south central pennsylvania to work on my bandit

According to my GSXR 1100 service manual
Intake                                                     Exhaust
1.333 lift 292 duration                            132 lift   287 duration

My 01-02 Bandit 1200 service manual, I could not find the duration
Intake                                                     Exhaust
1.322  lift                                            1.285  lift 

I thought the 1989 GSXR 1100 intake was 1.34, but that was not what the book said
The duration is advertised duration, but with valve lash, it's not that much. When I degree cams on the Bandit or GSXR, I use 0 clearance and from Open .050" to .050" before close, It is around 236 degrees.
I beleive the bandit cams are about the same.

88-89 750R head or 750F head on a 1127 or B12

These heads fit as they are, and give higher compression, better ports, larger squish.
In the case of the 91-92 1127R you'll need to use the 750 camshafts as well, since the
91-92 1127R uses shim type camshafts and the 750 head is forked rocker type. If you use the
91-92 1127R cam shaft sprockets they can be timed as in the manual.
In the B12's case you could use the B12 or the 750 cams (although they have different profiles)
but will have to use the B12 cam shaft sprockets because of the different cam chain.
In the case of the 88-90 1127R you can use the 750 or 1127 cams, and use the 1127 cam sprockets
(timing 'by the book') or use 750 cam sprockets (timing to be done by yourself)

I have a b1216 98 just installed gsxr 750 cams bigger ss valves and a delkvanic ss header. bike runs ok but lost alot of midrange low end grunt. just put 38rs on  hopping to gain some  back and on top. I was wondering what i might gain by indexing cams using stock settings.  cams have so much more than stock that Im close to spring bind.  thanks alot.

greetilngs. got bike running with 38rs.s now I need to learn how to drive it.  cv carbs make you lazy. So if the new bikes with onbd. electronics. are used we will lose a lot of skills. and when they break. look out. $$$ and proly danger of spills.  old school is really lookin good.  G1 is throttle pos sensor and air pump free.  second gear accelerator pump wheelies were unexpected. I bout slide off seat.  whoa.  sandy
