Title: Jet sizing chart for Bandos
Post by: billypotts on April 02, 2010, 03:25:20 pm
Has anyone got a part number for the carburetor jet? I believe its a sotck standard 92?

Has anyone got a conversion table of what size drill bit would produce a 100 size jet thru 105?

Is this information available online somewhere?

I do not know the sizing for the drill bits, but I get my jets from 600.  the legend jets work fine in the bandos

I believe stock jets are a 98 in the rear and a 94 in the front.  They offer a "high altitude"  jet kit which includes a 90 and 94 if I remember correctly.  a #59 drill bit is slightly larger than the 98 jet.

I found some great info after much searching that addresses the jet sizing. You are correct regarding the standard jet sizing. Terry from the engine department at 600 racing confirmed  that the stock jets are 94  for right cylinder and 98 for the left cylinder or the one closest to the firewall since it runs hotter due to airflow restrictions.

One of the three carbs I have had two 100 size jets. As the hotter months approach I'd like a larger size (105 or so). And since i have time why not have a some in betweens. For those that really want to fine tuning I've put together a table that tells you what size drill corelates with a specific jet size up to 120 size.

Yes, inex has 110 s,and most cycle shops carry an assortment of higher jet sizes.  Drilling is difficult to get right.  ?? How can you adjust a non adjustable float, I need more gas! Area 51 needs to know.  All help is apreciated

Everyone is talking about having to drill to adjust jet sizes?  I cracked our carb open and discovered we have two 94's in it, which explains why we we just a bit slower than some of the other cars, but the 112's fit with no issue.  What is required to drill for larger jets??

Can you send me a picture of the jets? If they are similar to the jets used on a legend car, I should be able to get whatever size(s) are needed.

One more question.  When going up from the 94's to the 112's, will I need to adjust anything else on the carb besides the idle?  Not sure if I need to adjust the two screws on the top that control air flow during idle?????? ??? ??? ???

Any time you change jets you will have to adjust the air flow also.
Glad you got it running good!

I knew I needed to....But I am an idiot when it comes to carbs and I didn't want to do more damage than good.  Which is usually what happens when I touch the carb!!...lol..... :P

Can anyone shed some light on how i would go about adjusting the air flow on the bandolero carb? I just replaced the jets with larger ones due to the extreme heat in Las Vegas.

Thanks

Talk to Ed at Bandostuff.com. He races Havasu and 'Vegas and should be able to help you with jet selection.

.0420 = 99.4 jet
.0430 = 101.3 jet
.0440 = 103.1 jet
.0450 = 105 jet

Hope this helps answer your questions about drill bit size! Good luck guys!

I have just started reading older threads as we are having hesitation issues on the drop of the green, once moving it seems fine.  Looks like a cleaning is in order.  Now I see this about the jets, can anyone point us to a good source of larger jets? I don't want to drill as I am sure to mess that up, also want the old jets to put back just in case.  Any pointers on adjusting the air flow after upsizing the jets?

There is no "magic" jetting for Bandos.  It will depend on how much airflow you have.  This will depend on how well your carb is blueprinted, and your particular engine's heads, intake, cam, etc.  Since you cant break seals and go into the engine to blueprint the internal parts, the only way is to maximize your carb on a flowbench, then tune carb, valves, jetting, etc. on a dyno.  EACH BANDO IS DIFFERENT.  Sorry, but thats the only accurate way to do it and maximize your HP.
