I just recieved a new venturi for my 2002 YZ250F so I can do the power now mod without tearing my bike down until the creation is finished. I will call it the "cajun now". I was hoping that someone could tell me how far the plate should stick out into the throat of the carb. Thanks to all the TT members for all the great info. :DPlease help.

My opinion would be the closer to the slide the better. This wil prevent some air from sliping down into the flow from between the slide and the Cajun now fin. After you finish your product, I think you should donate a couple bucks to Power now for their ingenious design. Goodluck!

As close to the slide as possible... without touching it...

Thanks guys for the info . I was hoping that someone who has done this mod might have the exact measurement the plate needs to stick out . Also, thanks to power-now and james-now for the idea and info.

it would be easy enough to figure out...

take the example in the JamesNOW! fact sheet

www.just-ride-it.com/powernow.pdf

The section after the 'T' section is what goes down into the venturi and into the carb...

You need to measure the length of the venturi piece, plus the distance into the carb to the slide face, then take off say 1mm or so to give you the clearance near the slide. You will then have the length of the part that goes into the intake tract...

HTH,

Thanks for the info guys. I started measuring and lining up the grooves tonight. I am using an old credit card for a pattern and then I will cut a piece of stainless steel to fit. I hope to be finish with this by the weekend. Any last suggestions from the TT crew?

measure twice, cut once...

If you slice you fingers with the sheet metal, a bit of superglue will hold ithe flesh together...

work slowly, and don't involve any powertools to speed the job up... hand tools only...

take pictures, report back...

have fun, always...

The tongue for the JamesNow/CajunNow should be around 12mm, that was the measurement from my original PowerNow and I've used the same measurements for my 2 avNow plates. You can see the plates on this page.

If you need any ideas here's some pics of mine that I made.

Thanks to all of you guys. I really appreciate the help. You are making it easy for me to do this mod. I think after I complete this mod I will try the aVx2 mod. I will take picture of my mod and keep you updated. By the way, the guy that said TT is not good anymore doesn't know what he is talking about. RIDE ON!

My creation is almost complete. Last night I cut the grooves in the venturi and finished the templet that I made from a Blockbuster gift certificate card. This was very easy to cut and deal with. The piece of stainless is the same thickness as the card so it worked good. My bubby took the templet and the stainless to work this morning to cut the piece for me. Of course I am making one for him also. I hope to have it on my bike by the end of the weekend. I will report back with the results. Thanks again guys for all of the info. This mod will cost me about $5 compared to $90.
