4500 RPMS no names no pack drill

I don't know about you guys but I bust it to red line through the first three gears about half the time or when ever I can. Am I hurting the bike? or just letting it run like a wild horse? I don't know but I love it and I am getting older so I better do it now while I still want to.

This bike as I have said many times before is just plain fun. It is not the fastest or the best handling bike there is, but the combination of comfort, power, and handling makes it the most fun bike I have ever ridden. "Ride it and you will believe"

She's a kick for sure. Love the torque of this bike. Ran her up to red line a while back and swore I bounced it off of a rev limiter. Anyone have an idea if I'm nuts? If there is one, what's it set at.

Steve that's the way I ride mine too. It won't hurt it. Use a good quality oil and shift it like you mean it.

[stevenolts]

From what I experience way too often red line hits way too soon for my liking. Maybe it is the fact that the F6B is so quiet. I am used to the Harley and my old Honda CB750K. When you take the CB750K to red line you know by the intense high revving engine you need to shift. (It really sounds bad ass) I still watch it and shift only when close to red line. The Harley was improved after adding pipes and power commander moving the rev limit higher.

I just need to learn to shift quick on the F6B. Maybe if I get some louder pipes it will help.

I tell you Steve she is hard to shift quick. No room for the foot. I shift better in tennis shoes. I may buy a new shifter and experiment with modifying it. It needs to extend out further and be up a little higher.

4500 RPMs ? Twist the grip to the stop and let the girl spin up to 6000 red line. You'll need to clean the seat off.�t�u�v

I have only one issue with that Socerer. My suggestion to launch at 4,500 RPM and shift at 4,500 RPM was for the rush of maximum acceleration not top speed. While trying to get to 6,000 RPM in 5th by shifting at 6,000 RPM in every gear including launching at 6,000 RPM you are not as quick as doing it at 4,500 RPM, torque is the name of the game not RPM.
I'm an acceleration junky and why I build turbo bikes and some times ride way to quick for my own good.
To get max aceleration you need to shift at the RPM where the engine is making its max torque and on the flat 6 F6B engine that is between 4500 and 4550 RPM(look at a F6B dyno chart) after 4550 RPM the torque drops off and as we all know it is torque that moves ya.
Sure, once you reach top gear your speed is going to keep going up to a point, but the time to reach that top speed will not be as quick by running the engine to red line, but by shifting every time at the maximum torque RPM, that's how you will get there quicker.
If you have ever been to a 1/4 mile drag strip you will never hear them engines wound up till they sound like they are going to blow, but they are shifted at max torque RPM and if you have ever run at one you should know this too.

You can prove this to yourself by doing a little test, it don't have to be a 1/4 mile. Now from a dead stop launch at 4,500 RPM and start counting to yourself, one one thousand, two one thousand, three one thousand and so on, shift every time at 4500 RPM until you hit 5th gear. The second you hit 5th remember the number while quickly glancing left or right for a refinance point on the side of the road. Now go back to your same start point and do it again only this time launch at 6,000 RPM and shift at 6,000 RPM reach the SAME number you counted on the first run and glance left or right to notice where you are. I guarantee you the distance traveled in the same amount of time will be less because it took you longer due to less acceleration.
Now if you have a local drag strip take the scoot there and do two runs through the 1/4 or 1/8 mile, one while shifting at 4,500 RPM and one shifting a 6,00RPM I'll bet any amount of money your trap times will be faster shifting at 4,500 RPM and at the end of the 1/4 mile so will your speed.

Yep that is what makes the F6B so fun with it gobs of torque and when you do get it where you can shift as fast as it reaches max torque the fun really begins.
I'm almost ready for a Kill button activated Pringel Electric shifter http://www.pingelonline.com/prodcat/...d-shifters.asp with a big red shift light that goes on at 4,500RPM then with one eye on the light and one on the road and my thumb on the button...........................never mind I see where this is leading. A blown F6B like my buddy Dave's blown VTX1800 he waxes my 185 hp Turbo X by about 300 hp.

My butts not big enough to launch at 4500 with out feathering the clutch like a mad man. Would be a gas tho. I read the op as shifting at 4500. As you can tell I'm not a drag racer, yet I am willing to twist her _ _ _.

[98valk]

I should ignore this, but I just can't.

Acceleration is about HP, not just torque. Torque x rpm. If you shift at 4500, you may be at max torque right then, but your new gear is way down around or below 80 hp.

The guy shifting at redline continually has 100 hp to the road through each gear. The guy shifting at 4500 is ramping from 80 to 100 hp in each gear. Needless to say, in a race, the redline shifter is going to win.

I would suggest that the best shift centers max and min rpms around the max hp. Redline looks to be in the ball park.
