75 750F. Just slip off the muffler and see how you like that! Open header 4 into 1. Rappa Rappa 7,000rpm cam comes on stock car bad ass ESPECIALLY if you do the engine  ;D Have your buddy ride it and nail the throttle going away from you. Even better but best if you're doing it. I had a really hard time justifying reinstalling the muffler it sounded so badazz.
As of today 3/13/2012 my original owner 75 CB750F has made it through 3 wives, er EX-wives. Free at last.  ;-)

Did you click the video????

I have 4-4 and no po po pop. Carbs are re jetted.

I only under stood half of what you wrote...


Are you telling me to video tape the bike accelerating away from a person in a car?

I can't do that... No brakes yet.

Yeah, video was pretty short. No real revving up?? Those drag pipes are bad ass. Got ear plugs?  ;)

I had been know to remove my stock muffler and run with an open header in the past. It sounds wicked. Like a race car with that open 4 into 1. My bike HAD a 812 kit and cam which made it sound even better than a stock bike. I have Kerker now and leave the muffler on. The engine has had a serious upgrade now but hasn't seen the street except for a few miles so far.

When you do get it on the road do a video for us. It's hard to judge it when you're the rider but a video will show you what we see.

You are correct. The idle needs a touch more. I like the idle as low as it can go.

My oil pressure is tits. Its at 80 psi when cold and when it's warm it sits at 60 psi.

I'm running straight 30 until its ready for the road. That engine has been asleep for 10 years.

I sounds cool, just hard to live with at 5,500 rpm for a few hours on the highway. No one wants to ride near you either.

That's a good point. I really don't want other vehicles near me. And besides, the guy next to me is riding a Dyna Super Glide with open pipes. We just might have discovered the safest way to ride.

Sorry man, some dig it and some don't. That's ok with me. You don't gotta like it. What matters is that I like it. My truck is just as loud. I don't fire my truck up or bike late at night. Being considerate of the neighbors and all.

Other then that... Let'er rip.

Nope. It's jetted. Just need filters. One cost at a time. It needs brakes first and foremost.

Once I get filters ill sync the carbs.
