What does your wide band say? Are you a running satisfactory A/F at idle, mid throttle, and wide open throttle? I have the same pitot setup on my turbo Honda CB750 (3/8" tube 90 degree facing into the air charge) and adjusted jets until the WOT A/F was happy. If it enriches a bit too much in...

You'll probably get a varied opinion based off of individual experience. My experience says the following, take it as an opinion: 11.0-11.5: Very safe, looking to lean to optimize 11.5-11.8: Safe, sweet spot for optimized performance without sweating detonation 11.8-12.2: Most likely...

Thanks for the reply and confirmation Turk. I'm glad you posted the pic of your sled, I missed the water/meth in the original poster's question and my question was based on assuming you had no meth (although those w/meth numbers are just as good and useful to see). Can you speak of what boost...

For curiosity purposes for a future project, do you consistently run your sled with stock compression, 91 octane, and 16 psi (and stock spark timing?) and thrash the throttle without reserve? Or have you ran an occasional tank of 91 through it when no other preferred choice was available? May...

With the small amount of gain from bumping up a 1.x:1 in A/F vs the amount of power you're seeing with 23psi I could see it being challenging to notice the change. A large change in temps could give you a more noticeable gain on the a55 dyno than the 1.x:1 leaner tune. Thinking your WB was...

k Good call on trying Sea Foam and resolving your issue with minimal additional work. Hope it stays on the up and up for ya.

It sounds like your idle circuits (passages) are plug with crud? If you are willing to go through with disassembling the rack, disassemble the carbs completely, letting fester in a bucket of carb clean, wash off, air hose the passage ways, and reassemble. As I noted in a prior thread I...

I agree with the intent of your reply, HIDs are proven and readily available. But to answer his question could the bulbs he's contemplating work in an RX? What's the available overhead on the RX's generator? Is there an extra 90 or so watts without being railed near 100%? I'm thinking that is...

Thinking if the bulb was a H4 and fit properly in the light housing you may have to figure in two things. First would be the extra 90 or so watts of power consumption (~45w x2 on high beam). I just got my RX and haven't gone down the path of figuring out how much overhead the electrical...

Not wanting to take away from a advertiser and supporter of this site, but there is another option for those who are looking to invest minimal and gain the safety of a higher output HID light. The kits are not custom and you have to be alright with tackling the wire management yourself, but you...

I agree with you, if ya want a specific A/F number get a wide band. To say that you can't read a new plug from a short tuning run that's too rich, too lean, showing signs of slight detonation, and or is spot on and happy isn't true. If you want to discuss PM me so we can stop trashing Nickrx1's...

I agree (WB), but shouldn't be necessary to dial in K&Ns with an exhaust.

Thanks for the correction on the pilots, I've searched to the best of my abilities and only found the following link which never really confirmed if the VM28/486 where the pilots that came with these carbs. http://www.ty4stroke.com/viewtopic.php?t=9378&highlight=vm28+486 Another confusing...

I would have thought your mid range/needle adjustments would have addressed your hesitation; it's right about that territory. Grader's advice sounds to be the right direction. Hesitation got worse when the needles where dropped, maybe you are still in a transition area between the pilots and...

Thinking that with your filters you should be around 165-170 main jet, one needle clip position lower on the needle (enrichment), and #20 pilots based on what others are jetting for with the air box mod and or K&Ns. I would think that with the exhaust I'd try 170s to be on the safe side and do...

See if you can contact the manufacturer of the pipe to see if they have any suggestions. They should be able to give you setup/jetting tips from what they found to work while testing. It would be in their best interests to do so. How's it run, what do the plugs say?

I only can add that a few years back when my friend bought a Hauck filter kit/jets the setup sheet instructed to move the needles one clip position richer or one clip position lower on the needle. Pulling from memory that it was one and not two, maybe someone else can confirm.

Agree with those pointing to dirty carbs/idle circuits, had this situation rear it's head with my CB750 cycle. Erratic idle, twice I completely stripped and cleaned the carbs with an air compressor and can of carb clean; twice I failed to free the crud. On the third attempt I dunked all four...
