I know, I know! Update coming soon.

Ruby, I have read that you installed CDI from ThunderCat. And what for? higher revs? more advanced ignition? Or anything else?

I am doing such swap just right now. I'll stay in tune )))

Kebab19 and other guys, please tell me if the shock on photos is just right unit.

It just includes mains jets?! 


It will need more than that. Glad I didn't buy from them.

No!  pivot jets (1set), main jets (2 sets. I asked them for KN+slip-on and podfilters+slip-on sets) and some twist drills and some other parts for setup. Plus brochure with instructions and tips for tuning and faster throttle response.


As for DragStar kit It also contains 2 steps of main jets. We are still thinking about which air finter to use - KN air filter or still ride with OEM one. In this case they advised me to try 2 variants of main jets.


I have thermocouple and wideband oxygen sensor equipment but no moto dyno. Will try to check afr in motion.

where have you been, Ruby???     I've just bought 2 kits from them. 


For Fazer 600 and VX1100.


The kit contains 2 sets of main jets. Will set and check temp balance and a\f ratio.

Sorry for stupid question, but all links for emulators are for H.D. ones not for Fazer. is it correct?

Std main jet is 115, am I right? 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 didn't open my carbs yet, but what to compare. My carbs seems to me to be virgin w\o any mods.


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.


Ruby, you have already driven Fazer with pods. did you touch filters by legs? they should exactly near knees?

Thank you, Iwill read the topic and ask questions, If you don't mind.
