Here is a great instrument whichprovide good helpin tuning the bike. http://www.autometer.com/cat_gaugede...604&sid=11These items are relatively cheap on ebay stores.

The basic principle for tuning a carbed bike is:
1. Adjust the float levels per spec.
2.Select main jets so the A/F ration is about 13 to 1 at wide open throttle under load
3. Adjust the height of the needles so the midrange A/F-ratio is about 13 to 1 under load
4. Adjust the pilot jets so the bike responds nicely from idle and up to a few 1000 rpm's

Couldn't find the price or how it hooks up to our bikes.

 

Here is one on ebay, there is plenty of them http://cgi.ebay.com/ebaymotors/AUTOM...spagenameZWDVW

The installationappears to bequite simple. You need to weld a M18*1.5 nut on the collector, which willhold the included BoschWide Band O2-sensor. This stud is already in place on later FI-bikes.Then it is just to interconnect the gauge to the O2-sensor (Lambda probe http://en.wikipedia.org/wiki/Oxygen_sensor), plus 12V and ground.

My unit was sent from US this evening, I'll report my findings when it is installed. I guess it will take a week or so for getting it to Sweden.

 

awesome. I am much interested in hearing how it works for you. I know mine is out of tune and needs some adjusting. This instrument sounds like a godsend.

 

Very cool, keep us posted. I'm sure it will be much more time consuming to tune a carbureted bike than a FI bike. Much easier to change a program than to replace or shim needles, swap out jets, and things such as this. But still worth looking at.

 

The meter is in place and works as expected :-)

The O2 sensor (wideband lambda) is screwed into a threaded stud, which is welded to the collector. I thougt it would bedifficult to drill a 20 mm hole in the stainless steel tube, but it was easy with a15 buckHSS conical drill.

Or you can DIY like I do and get this:

Great link, thanks. I may use itin case I need another sensor.

 

Hey, R1000, any more gauges and you'll need a pilot's licence for your 'Busa !

 

Yeah, another license would be fine, just in case ...
