Thank you very much Chip!!!Depends on what works best....
We have seen the same thing. This why it is very important to check the AFR map before you apply it. If you end up with an outlire (high unsually high or low number) simply plug in the logical number based on the cells around it.
The Stock o2 sensor is narrow band sensor that tells the ECU that is within a very small range. Either its in or its out. It doesn't have the capacity to make mapping changes and is not a closed loop system like a car.Hi, I'll try not to sound too much like a noob but have a couple questions.
Just got back in the saddle with a k8 1000 - put on the single Yosh TRS 'slip-on' that removes the collector - maintains the O2 sensor. Is the stock ECU (if that's the right term) going to accomodate for the added air flow or am I at risk of running lean without adding some sort of fuel control (PC III or Bazzaz)?
Next, I've read your feeling on the TRE, so is my money best spent on a PCIII or similar if that is the extent of what I am going to do to the bike? I have a qualified shop by me that can Dyno it to get it right.
Yosh Double Stacks - No.....they are way to expensive!!!!!!!!!!!!Hey Chip - Kudos for sharing valuable info unk
Have you used the Yoshi Double Stack Intake Trumphets & if so what do you think?? There are alot of money for 2 stacks!
What max compression ratio would you advise running on 95RON Octane pump gas?
Have you any experience/opinions with the new type BPF's (Big Piston Forks) & if so do you know if they can be retro fitted to a K6 1k easily without swappig/modifying the stock triple clamps?
Is there any way of getting a K7/8 head & valve to fit a K5/6 & if so are the benefit worth the effort??
Your tuner is an idiot. What your discribing does not make since. Leave it alone or take it to somebody competent.Digging back through my old emails, I happened on one from my tuner. When he adjusted the valves on my K6 a couple of months ago, he happened to notice that the cam timing was retarded. Like, 4 degrees on the intake and almost 8 on the exhaust (IIRC). We are going to get a set of adjustable sprockts and adapters (stockers are pressed on). Once this is done and the timing is set to stock specs, can I expect more low-end and midrange?
We did it at Laguna this year....on pit wall. It wasn't fun.why would he degree the cams while doing a valave clearance? Weird.
I tried it a couple times in the bike, but now that i am older and wiser I only degree the cams with the engine out of the bike. So much easier.
Nope. Polishing won't do anything....in fact it might make it worse. You need some texture in the ports to induce tumbling and break up flow on the port walls.Thank you very much Chip!!!
That's what I thought.
And one more Q for you:
Stock engine. Polishing ports without actually changing their shapes - is it worth the pain?
What kind of gain can I expect, if any?
:scratchYour tuner is an idiot. What your discribing does not make since. Leave it alone or take it to somebody competent.
Cam timing cannot change by itself. Cam timing is what it is. There is no retard or advance. Because the cam timing is not stock does not mean its wrong. In fact lower cam timing will result in more midrange not less.:scratch
Really? Wow. Guess I've been taking my stuff to the wrong guy for the past 12 years or so. I'll let my AFM friends know too. Thanks! :lol
It will effect it some, but the current AFR stuff is not that good and still needs a good base map to work really well.Chip, how are dyno shops going to stay in business with these "self tuners" on the market?
Many people will think they won't need them anymore and that is a shame.
I can't even guess what is broken. Sorry.Hi, I have a hayabusa 2000 and The problem comes when the bike is heated and then shuts down and I have to let it cool to re-ignite... what do you think????? thanks
100% not true. It is absolutely critical to balance motorcycle wheels/tires. They don't "unbalance" unless something dramatic happens.Hi Chip, some guys say that motorcycle tires does not need balancing, or you can just skip that, saying that a small brake can re-unbalane the tire ... how true is that , do you balance yours? another one is , the 16.5 inch racing wheels instead of the 17" stock, is it a big difference? do you still use the same 180/55 tires on it or need a different size?
Yes. Press Release next week. :biggrinare you guys racing AMA/DMG 2009 ???
unk unk unk keeping Ben ?Yes. Press Release next week. :biggrin
