Camshaft specs... The next project!
- Thread starter Marthy
- Start date
My guess is the mid range is nice because of the smaller intake ports and valves of the 6R vs. the FZ6. Same reason for lack of top end rush. That said timing the cams a little more may help. Maybe advance them a little more?
And until you can get on the dyno its hard to know what the correct map is.
If you can stick with the Factory Pro shops as they use a 4 Gas instead of only an O2 sensor. Aim for 4% to 5% CO and you'll be spot on.
Looking forward to the end product Marty.
You're right! The smaller intake runner and throttle body is what make the mid range so great. But don't get me wrong, it doesn't feel flat on top... just not as big of an improvement. The engine tune is so different with those cams. As much as I needed to "dump" fuel with the stock cams... here just like you said, lean is mean. More like it suppose to be.My guess is the mid range is nice because of the smaller intake ports and valves of the 6R vs. the FZ6. Same reason for lack of top end rush.

It almost pull like a twin on the bottom with a good top end... hard to explain. Under 4K it's absolutely dead... then it kicks in like a 2 stroke with a huge mid range then pull all the way to 12K. Really like the way things turn out.
Just need to find a good Dyno tune in my area that are still open with a working Dyno... lol
I'll keep you posted.
Has Hellgate strongly suggest me, I found and called a Factory Pro Dyno service place in West Melbourne, FL The gentleman on the phone was really cool and all I need is to schedule an appointment... they don't do dyno tune on Saturdays. Since theyre about 100 miles away from WPB... that's as all day project. I've been told it's around a 4 hrs project and It should cost about $250.00
Until then I will enjoy my maps and massage it if needed... The bike run amazingly well has it is right now. Can't wait to have a dyno duel Marthy vs. Factory Pro... lol
I'll put the numbers...

I'm still running 17/44. Can barely keep the front wheel on the ground as it is... lol That should stay has is for now.
I wish! I need a day off during the week!!! No dyno run on Saturdays
I really like the way the bike pull... but I won't eyeball numbers. I'll wait for the real ones... 6R Blackout

Marthy correct me if I am wrong but I believe I came across a you tube video with the new cams of you doing a start up? If so it sounded really really good! Do more please!!!

I was just thinking out loud (often dangerous) but if the fz6 has a detuned r6 motor and the fz6r has a detuned fz6 motor, is their a way you could disable the rev limiter, and use the full potential of your new cams. From my under standing the bottom end of all 3 are pretty much identical so all 3 rotating assemblies should be able to spin 16k all day with out breaking a sweat. With a reflashed ecu from ecu unleashed you very well might be able to make pretty close to stock fz6 numbers on the dyno, unless what I'm thinking cant be done?
You are partially right. To get 100% out of the cams (for peak HP) I need more RPM. But so far my biggest gain has been in the mid range. Bellow 4K the bike feel numb, at 4K the engine pull like a twin and at 8500 it gives another kick all the way to 12500. I'm trying to get day off so I can tune it p on the Dyno. From there I will know exactly where the power/torque curve looks like. I can play around a bit why the cams timing to adjust the power band.
So far, whatever the numbers, I'm very happy the way the engine pulls. It's perfect for street driving. I gain about 5hp with the exhaust.. My butt Dyno tells me I gain as much with the cams at peak, but a lot more in the mid range...

Well is there a way to up the limiter?
Ah... yes. (forgot that question...) It can be unlock with PCV (password required) but mechanically I'm not sure how much more the valve springs can handle. They already have to manage almost 1mm more lift...

Ah ok, we'll in that case I wonder how much a new set of r6 valve springs would cost, or im sure you could find some off something to work on eBay, if you wanted to go that route.
Totally different cylinder head...
Rev x-tend or something like that. Honestly, not something that can be used if you don't change valve spring and cams... You might be able to get away if you want to spin the engine 13K - 13250 but not much more than that I will think so. Personally, I'll manage to make power under 12500 RPM.
I've been thinking about for a long time! "How could i extend the rev in my bike?" Is that what you're saying? is there such device? Good news? I don't care if i get more hp at the end... as long as i gain it!
