Can you let me know what jetting changes you made to your carbs please?
Is there an echo in here?
Do you recall what the original rearset frame mount measurement is between centres?Mark
No problem at all. That's what this is all about, helping each other.
Std main jet is 115, am I right? And they are all the same in all 4 carbs?

And they are all the same in all 4 carbs?That's what were in mine.I've been trying to change the needle jet in accordance with the instructions that came with the K&N pod filters, but with no luck as Mikuni don't make different jets for those particular carbs.Had a good informative conversation with a guy at Allens Performance who explained to me why pod filters are not a good idea. He basically told me to throw them away and put the standard airbox back on! He's right. When you open the throttle on a CV carb you don't lift the slide in the carb, you open the butterfly. The difference in pressure between the air box and the engine (I think) then makes the diaphragm at the top of the carb lift the slide at the correct speed. This means you get smooth fuelling. By removing the airbox and fitting pod filters you screw up all the hard work done by Yamaha to find the best size and volume of airbox. That said I have a ZRX1200R I have fitted pod filters too with an Ivans Performance Jet Kit, designed specifically for that bike with pod filters, and it runs like a dream. That's because Ivan spent hours and hours on a dyno with a ZRX to come up with the best solution.So it's doable with pod filters, but will probably take a long time to get right. And that's if you know what you're doing. I don't!As I see it there are a couple of options open to me:1. Measure the volume of the standard airbox and try and create something similar to fit in with my build aesthetics.2. One of my buddies suggested fitting one big long air filter covering all four carbs so as to create a small pocket of still air.3. Fit some slide carbs. That's the very expensive option as you're looking at around £700 for a new set.I will probably do the best I can with what I have and also look into option 1. If the build turns out as well as I hope then I may stump up for some carbs in the future.They guy at Allens did give me some other people to ask, but he wasn't hopeful of success.
I contacted to 6sigma carbs tuners from US about correct jets for my Fazer.They told me that pod filters is a good idea for accelertion but at high speed they suffer from air turbulance and the bike could have less top speed or so.Also they send me some tips tuning for faster throttle response. I think you all khown it all.Actually I put "pod-idea" on the bookshelf for now and just order KN filter in stock airbox.
[/size]Ruby, you have already driven Fazer with pods. did you touch filters by legs? they should exactly near knees?[/size][/font][/font]
It just includes mains jets?! It will need more than that. Glad I didn't buy from them.
Any chance of a photo of the kit contents for the Fazer?
I know, I know! Update coming soon.
