Hey... I'm new. I've been riding an '88 CBR-600 for a couple months now in a small town. The dude who had the bike before me must've been an idiot because he put a SuperTrapp exhaust on it (and not one of the new ones either) so it's pretty damn loud.
Anyway, I live in a small town, speed limits average 30/50kms and my speeds are 50/60km/h, I was just wondering what my revs should be like in these speeds. I can't really tell (and I'm not certain in my ability to tell) if I'm boggin the engine, so I just wanted to know what an average RPM would be at these speeds, I think I might be running a gear too high a lot just because of the sound of the bike (used to cars). Any help would be appreciated. Thx for your time.

Your pipe, most likely, is a lot louder when you have your helmet on. I used to only have one helmet and when my girl rode, I made her wear it. Everytime I rode the bike without the helmet i used to get pissed. My pipe sounded like it was screaming and not that deep choppy popping I was used too. Sounded like a dueled out Chevy with the helmet and sounded like my 95 Tercel with the Helmet off LMAO

Then on the other hand, maybe you've heard the bike when someone else road it by you? As far as your revs, sorry I don't know much about the older CBRs. I just run my R6 where it's comfortable for me, Bike vibrates like crazy above 8K and a constant speed. I usualy ride between 6K and 7K. 1 or 2 downshifts from halling butt :D

Just be alert and ride safe...later

Wow.

Yeah, you could be right, I've never really heard it without the helmet. Thx man, I've been running it at like 4 tops when I'm doing 30-60 km/h. You could've saved me a lot of trouble. Again, any replies are welcome and thx man.

Huh???:confused: :confused:

You sound like one phuked up lil' cracker. Please explain this further. Do you only take your earplugs out when you put your helmet on?

Maybe I'm the only one who thinks the sound of my bike is muffled when wearing a helmet?

yeah that does seem strange to me. I can't hear my exhaust at all with my helmet on, only if I take it off and stick my head over on the exhaust side of the bike.

Well, I went for a rip last night and ran it a gear lower everywhere, about 4.5-5k. Sounds like it runs waay better, no chugging at all, just a smooth (LOUD) hum. It redlines at 12,000 so I think those RPMs should be right.
On a side note, whenever I would pull up to a stopsign I could smell some gas fumes, not tons, but the odour was there. The dude who had it before me never got it jetted for the pipe, and I don't have the cash to do it now but I can adjust the backpressure on the muffler with those disks. So basically my question now is: Running rich, should I make more or less backpressure?

Also, my neighbours officially hate me now, thx ;)

I've got an F3 and I presume that it revs pretty similarly to the F1. I ride around town in 3rd, sometimes 4th gear. 4th gear @ 60kph is ~3800rpm on the F3. I think you're nearer to [email protected] in 3rd gear.

I try to keep the revs above 4k, but not more than 7k around town. I do a lot of 'round-town' riding and keeping the revs up a little bit helps keep the carbon build-up in your cylinders down.

Hope this helps.

I was moving my bike to a different storage facility yesterday Another Garage other than mine) Becasue I'm going out of town. And I was thinking about how you guys have been talking about riding your bikes at low revs. I don't know the KPH to MPH convertion and what that means in RPMs for you Blackbird. But on my bike the power band doesn't kick in real good until about 7K, which in 6th Gear is about 67 or 70 MPH. Granted, 60 MPH in 2nd is somewhere in the 8K to 10K range. By the way, It redlines close to 14.5K.

Ok to my point. I'm assuming that Cagers are idots where you guys live too. But just about everytime I ride, day or night, some moron runs up right behind me. If I'm doing 40 - 50 MPH in 4th Gear, I'll have to get off and push to get it going faster until it gets to the Power Band. I usually ride in 3rd @ 43MPH, which I think is about 5K to 5.5K, except on the Highways. It's more comfortable to me, because in 2nd @ 43MPH, the bike vibrates way to much and my arms get tired faster. Also, I'm closer to the power band, which still takes a second or 2 to kick in or I'm a split second from dropping 1 gear and moving out of the way while showing that cager I think they're #1. When I'm in 4th, I don't feel comfortable in the ability of the bike to perform to move me out of the way, without having to shift. So I say eliminate the shifting, ride around in a gear that's comfortable to you, but one that does not disable your ability to ride defensivly.

As far as Sound, if I thought the bike would be ok and it was legal, I'd take the Pipe off so it would be louder. At least then, MAYBE the Cagers will notice me more and not try to pull over in my lane so much. But I doubt it!

It doesn't hurt your engine, that's why street bikes have rev governors, so it stops you before it hurts the engine. If you don't open it up every now and then, for example, if you "baby" your bike by never going over 7,000 revs, you will get carbon buildup.

People that never let their bikes redline are just causing problems for themselves. These bikes were made to redline, and that's where the power is.
