I have one in my RR now and I rode my bike the whole week to work. Well I had to fill up 3 times. that will last till sunday. My friend who rides a gsxr 750 thats all beat up only filled up once so far this week. He uses 87 I run 91. We both have pipes on the bikes. Would it make a huge difference in gas consumption if I removed the PCIII? And if I did remove the PCIII would I have to do anything other than just disconnect it ?

 

[Moeman]

From what i understand removing the PCIII will actually make your bike consume
more fuel

Personally i think that statement is a myth PC or not my bike always used
a tank of fuel during 115 miles then my reserve light starts to blink
and as long as i stay below 5000 Rpm i can get another 35 miles
then my tank is empty

Now i know the PC owners will have a few pointers to add
so the more info u have at hand the better your decision might be
Best of luck

I am no expert, but I would say it would have more to do with the sprockets and riding in a higher RPM.
I don't get the greatest milage from a tank, but I alwasy just assumed it was from the gearing.
Also depending on what map you have running, you may be running very rich.

What conditions do you ride the bike in?

RPM?
Distance?
Speed?
Style (spritied or commuter)?

I usually keep it at 8-10k rpms
My work is about 30 miles each way
I keep it between 80-95
a mix of both

what about your map is it a custom map or just one off
the web ?
To utilize full benefit of the PCIII a custom map would be the
way to go
What color is your exhaust end cap ?
Your answer will give an idea is the bike running way rich
rich or lean

 

[Guest]

Ah, that explains it clearly.

dibs on parts when it blows... seriously, that's like 3rd or 4th gear riding! why in the world would you be riding at such a high RPM like that?

It is a custom map they did the dyno and the whole deal.
It is a 2bros Titanium
I never checked the color of the end cap.

Well maybe I am a little high on the RPM's so what range should I be in?

 

[Black_Bullet6]

yeah i kinda would like to know as well. i usually ride in the 8-10 areas myself.

with 15/45 8 grand is 80mph, in 6th gear.

So we can start to eliminate some factors
1. It aint the map ( custom map should be the best )

i think its probably the way your ride like knight said earlier
try to use the power differentley and start changing the way you ride
give it a week and see if these changes made a difference

Check out the math of gearing

who said anything about a 45 tooth rear?

 

[CrazyLocoDude]

I have -1 in front and stock in back

 

[Guest]

it's the combination of your style and your RPMs. All 8 injectors are working after 5k RPM. if you're riding highway, you should be in 6th gear to conserve fuel. The engine can occasionally take 15000 RPMs, that doesn't mean anywhere in between there is safe. You keep that up and you'll spin your bearings out.

 

[CrazyLocoDude]

Ok I will pay attention to my rpms tonight on the ride home.

 

[mikespike2]

You keep that up and you'll spin your bearings out.

Spin your bearings out?? Please.. how do you ride on the track? Ok wait, how should you ride on the track? HIGH RPM... And track sessions are usually 30 minutes, and youare on the power more at a track session than cruising.

That's the point of the oil channels that feed into the rod and crank bearings. Now if you are low on oil, then you will spin the bearings.


Let's make a bet for pinks... I'll ride for 1 hour at 10,000 rpm and if it blows you can have any parts you want. If it doesn't, I get your bike. And he rides for less than 30 minutes at his speed and distance, so I am even increasing your odds by 2 fold.

 

[Guest]

not a chance buddy. With those conditions, you'd take it for sure. but let's try this:

Over time that constant high RPM does a number on the crank bearings. Ask any seasoned full time racer here if you don't believe me. It can take it, but not for extended periods. He's doing it 60 min a day 5 days a week for a year, not including any possible track or canyon weekends or errands that come up after work. That's serious strain on the motor any way you look at it. Something will fail and i'll put my money on the bearings going.

 

[NewRedRider]

Keep your rpm's around 6-7k on the street. Good fuel economy and you still have enough torque to get out of the ole blue hairs way! If you're still getting bad gas mileage put it back on the dyno and check the A/F ratio. Have you changed the air filter lately?

 

[mikespike2]

I still don't think it would fail that soon. I just don't think the bike's made to cruise at 5k rpm. It's made to be ridden.

In fact, I don't know of anyone who has ever had the motor completely die (like bearings) on their sportbike. I'm interested to know, have you, and what happened?

 

[Guest]

Ask a full time racer. Ask them how many engines they go through in a season, or how many times they have had to rebuild it. The bike is not made to run at 10,000 RPM constantly. If it is, it will fail.
