So .8mm is the acurate number sorry for the scare. He says any cb750 or cb550 or cb350 can safely go .8mm

I HAVE MY FIRST CB750 IT'S A 72 & I LIKE IT BUT I'M GONNA BOBBER IT OUT. JUST NOT ME THE WAY IT IS. I AM PICKING UP A 75 CB750F OR SS (NOT SURE WHICH IT IS) PARTS BIKE, DIRT CHEAP, THAT RUNS & HAS SOME REALLY NICE PARTS ON IT. IT HAS A 4 INTO ONE PIPE, KONI SHOCKS AND SOME OTHER STUFF THAT I WILL PUT ON MY 72. BUT I'M THINKING I MIGHT TRY TO MAKE THE 75 INTO A STREET/STRIP BIKE, REAL LOW & DRAGBIKE LOOKING. I'M NOT LOOKING TO GO 9'S OR AIR SHIFTED OR ANYTHING LIKE THAT, BUT SOMTHING SORTA DRAG RACY, BUT DRIVABLE ON THE STREET. I WILL DRAG RACE IT HARD THOUGH, FULL THROTTLE LAUNCHES ON THE WHEELIE BAR , BUT I WANT TO FOOT SHIFT IT. ANYBODY OUT THERE WANNA GIVE SOME MORE IDEAS ? I WOULD MODIFY THE MOTOR SOME BUT NOT TOO MUCH, YOUR THOUGHTS ??? THE CLUTCH IS SOMETHING I'M NOT SURE OF THOUGH, WOULD HAVE TO HANDLE THE HARD LAUNCHES & DRIVING ON THE STREET. SEND ME SOME PICS OF YOUR BIKES TOO. THANKS, JOHN       

Yep.  I drag mine.  It is also built for the street, so it serves two purposes.  Fun to drag and ride on the street.  If you are going to drag it be sure the motor is stoutly built or you will be rebuilding it.  I run in the 11s with mine and I am still a rookie on the strip.

How many times have you had it at the strip Art? Also...what was you best mph??

Three times this summer/fall Mike.  I was rained out 5 times.  Two of the three nights the air was heavy and I had similar runs to my first time - high 11.9s.  One of the nights was cool with lower humidity.

1/4 Mile ET:   11.740
1/4 Mile MPH:   120.260
1/8 Mile ET:   7.656
1/8 Mile MPH:   94.700
0-60 Foot ET:   1.895
Air temp:           79 degrees
Rider weight:      154 lbs.

Spun the rear wheel a bit and then it hooked up.  My 60 ft. time hurt me.  Ran it to the rev limiter on every shift.  I ran these numbers with the new tune I put on the bike.  Dropped the needles in the CR carbs and changed the jetting and timing.

Each night it was one run and done because the line was long.  Friday Night open racing gets CROWDED!  Everyone wants to run their motor and it is a mix of cars and bikes.
