Wanted wideband

im looking for a cheap wideband so i can tune my bikes carbs anyone have one laying around?

 

Gunson Colortune. Cheap, effective, and won't require welding in bungs.

 

i cant find any in the usa do you know if they have any here or is it mail order only?

 

Len (Chacal) has both the Gunson Colortune and the Morgan Carbtune. Start a conversation with him if you're interested.

im needing a 10mm

 

I'm sure Len will reply, but here is the 10mm from his catalog:

ya its for another bike but i figured i would ask yo guys. the bike calls for a NGK CR9E

 

so i was reading the thing on there about the color tune and it says that its only for idle? a wideband does idle and running though right?

 

Colortune is used for pilot mixture. You can't analyze your bike off idle unless its under load, so the colortune is not applicable off idle unless you could somehow watch it while driving. Regardless you can only run it a few minutes anyway.

Wideband will give you the AF ratio at any throttle but unless you can log it along with other data such as throttle position/slide position and RPM its's going to be useless. Plug chops are the way to go. Its a little time consuming and you need a stretch of long preferably private road but it can be fun.

 

ok ya becuase im stroking my motor out and it willget another 60ccs so im guessing thats going to mess with the fuel air mix

 

Uh....yeah---- you're gonna mess with everything. It's almost like putting on pods......only worse

 

the manual indicates you can use it to check main jets as well.
you can down load the manual from mfg

I made a 10 mm color tune for someone there are instructions on the internet

 

so i looked it up so you can make them using apoxy? is that correct?


and yes i would guess its as bad as messing with pods but im also changing the velocity stacks by making them shorter so im really going to be in for a fun time

 

Just do one thing at a time, and take copious notes.

A Colortune will tell if you are close off-idle without load so you don't have to spend as much time with plug chops.

 

yes but do not use 5 minute epoxy . the longer cure the stronger.
I used a plastic screw cap on the end to retain the pour.

i would recomend a face shield when viewing the plug.

 

i was hoping not to have to buy a lot of jets over and over again to get it to run right so i thought i would just do it all at once

+1 Polycarbonate, and thick.

 

what about my helmet i have a rf1200 you think that would work?

 

If you do buy the colortune, make sure you buy new through a reputable seller like chacal or keep an eye on what you are bidding on. There are two models, the older one has some flaws that are corrected with the newer one. I thought I got a heck of a deal on mine until I had issues with the spark jumping outside and found out there was an older one. I was able to fix but it reduced the area of the window I can view. Doh!
