After reading multiple posts regarding pods and jetting and carbs etc.... I came across comments in the “carb swap” forum by murrayf regarding the air flow restrictions we can expect to experience by using pods. I went out and took mine off to see what the excitement was about and found the following. Perhaps all you all knew this, I’m just a little slow at times.

I modified my pods as noted in the photo, it made a substantial difference in performance running 125/90 jets in stock Keihin carbs, straight pipes and no pre-chamber (H-Box).

I'm gonna need to try this tomorrow. What kinda glue did you use? RTV? Epoxy?

 

[KeysCX]

First I sanded the chrome with 100 grit to put some tooth on the steel surface, then I used JB Weld which held good on the steel but it didn't hold to the rubber. So I used Gorilla Glue which so far seems to be holding firm.

 

[KeysCX]

Oh, I also cut away approximately 1/8" of the filter end cap ID with tin snips to open it up even more.

 

[murrayf]

i cut the section away on the rubber then dremel the metal cut out and then re attach the rubber boot with 3m weather strip



adhesive



DAMN pods

 

[Chzdanish]

Could you just remove the portion of the rubber that covers the ports to eliminate the need for glue?

 

[murrayf]

the metal also occludes the port from getting the best sensing so wide open near the port is better



larry and i have known about this for a long time (me for over 25 years lol) and we just mod a mark the pods so we know where the cutaway is to install them



as larry is way more detailed than i am he is going to modify some for a bike he is working on now and document the way he does it and post it

 

[Chzdanish]

Good deal. Mine came to me with pods, so I look forward to that.

I just received my pods yesterday, http://www.mikesxs.net/product/15-0152.html



I slipped them on, tightened them up, and stood back at their beauty. Then this morning I see this post. UGH! I'll have to go back home tonight and see if this brand also cover up these ports and such.

 

[murrayf]

yup they do



i bought some of them to lol

 

[Chzdanish]

I got lucky. Mine don't have that ridge inside. Although, in a way I was excited to see some sort of magic performance change in a bike that already runs well

 

[LaGrasta]

Thanks for the confirmation Murray. I guess I'll drag out the Dremel and have at 'em.

I've been fighting my carbs for weeks now. I know what lean feels like, and the bike feels lean. I put in a bigger jet, the bike still feels lean everywhere, but wide open it falls on its face, hiccups, and gives me almost rich-running characteristics. Saw this thread today, pulled the pod filters off and ran it without any air filter... and holy shit, I'm still running lean, but now it just pulls and pulls at wide open throttle.



Still going to drop some serious dime on Murray's carbs (this weekend even), but at least now I know why it was running like ass in a can.

Where did you get them? Thanks!

I didn't. A PO put em on.

So, without wishing to sound like a complete burke!!

, would it be fair to say that unless you either carry out the mods above or have pods without the ridge then that goes a long way to explain some of the issues that occur when fitting pods?



Cheers - Shirty

 

[murrayf]

having the port occluded just aggravates the problems the pod does not close it off completely making sure the sensing



port is wide open helps a bit in slide response and helps a bit in overall throttle response and delay it in no way



restores the original conditions

 

[Shirty]

Cool, cheers!

It should, yes. Some of the issues.



Strange thing is some bikes take to pods fine. My EX500 ran with pods and a 2-into-1 with only a couple of tries with the jetting, and it was an obvious performance INCREASE, not a decrease (It would never pull the front wheel up on the 2nd-3rd shift before the pods). But the CX carb design does not do well with pods for some reason.



Right now I'm running no filters at all, just to play with the jetting, and teh bike runs better... but still not great. Instead of spending days troubleshooting, I'm just going with murray's carbs. They're the carbs I wanted in the first place... in fact, the next step for me was to purchase the mikuni's off of eBay and figure out how to mount them... but Murray's already done all the work! He beat me to it, and actually made one hell of a nice looking kit. Even worked out all the jetting too, so that man is getting my money.

I too have purchased Murrys kit. Although with only one jet change on my stock carbs even with the ports blocked off, the bike ran great! Not lean at all, almost a little rich. I have purchased different filters and they arrived today with no ridge inside! Course with the new carbs guess ridges wont matter much. Guess I got lucky with my stock carbs.
