ratio

Ok, all you guys that put your bikes on a dyno, on average changing one jet size changed you air fuel ratio by......how much? I know its not going to by the same for every motor, pipes and engine mods will effect it, but it should be able to be used as a ball park figure.

Hi, I come across this product on ebay. http://www.ebay.com/itm/MOTORCYCLE-52mm-Racing-Gauge-Air-Fuel-Ratio-WHITE-Back-light-/321032174453?pt=Motorcycles_Parts_Accessories&hash=item4abf023b75&vxp=mtr Anyone uses this before? Can I use this to tune the carb?

I've been asked what the Compression ratio is on my 89 Max. I searched the web for an answer to the question of PSI Reading on the cylinders vs actual compression ratio. Best answer I came up with is the compression reading divided by 14.7. Stock Vmax's have a 10.5:1 compression ratio. My 94...

Where the heck is the procedure for setting the A/F screw positions? I know that a dyno or an A/F meter is the best way, however I thought I recall a procedure to get you close for those without access to these resources. Since waking the bike up after it's long winter nap I have had a...

Ran across this today, thought it was pretty interesting.... Especially in how static CR isn't what you end up and how it also depends on the Cam etc as well, something I knew but never had explained this well...

Given the same P:W ratio, will a light bike leave the line faster? Take a 700 pound bike/rider with 100 hp (7:1) vs a 450 pound bike/rider with 65 hp (7:1) ... which one leaves the line first? Given for the sake of argument that "power" is just that ... total power. Let's pretend the...

I added a Marks 4-2 exhaust with the 14" cans and had my bike dyno'ed to see what adjustments need to be made. The dyno chart shows me very lean at idle then rich from about 2K all the way to red line. My A/F ratio from 2K up is around 12-1 I would have thought a better breathing exhaust would...

Would someone know the ratio I believe it is 2240:60 (2240 rpm cable is 60mph).But it gets a little confusing doing a search a the net some info said only 19" and 21" wheel use the ratio other info said all japanese use this ratio.Well I have a 18" stock front rim so kinda confused :ummm::bang...

Anybody used the LM-2 Innovate motorsports air/fuel wide band kit? 559 $ with bells and whistles Some threads vote positively towards the older LM-1 ( 379 $ on fleabay with rpm signal cable) Looked at Dynojet wideband commander too :ummm: but felt more at ease with the Innovate ( maybe just a...

I wish someone could figure out how to lower the gear ratio in the rear diff to get the bike to top out in the 1/4 mile. Dropping to a 17" rear wheeel only helps a little.Still in 4th at the finish line. Need more horse power:bang head:!
