Question Uni PK92 Pods for Earshave? Source for jets?

Pulling the stator and can't see leaving that air box and plumbing in there. Would've liked to have ridden more miles to feel the difference in performance, but I'm taking everyone's word on it.

Anyone using these or have an opinion on them for the earshave mod? The Uni PK92 pods aren't as sexy as K&Ns, but they're half the money and foam instead of cotton. If I shop around I can find the Uni with chrome caps.

Did a search here and found some 5-6 year old posts where riders were using them. Just want to try and see if that info is still good.

Also, anyone know a good source for jets and shims?

Here's the Uni pods:

Well I did some digging and found old posts where the Uni PK92 was used with no problem. So I snagged a pair for $25 shipped.

That leaves jets. Where to buy and what size? I'm getting closer on the where, but the size seems to be all over the place. I'm planning to keep the stock exhaust for now and I'm at 600ft most of the time.

I see some people near sea level going 142/42, and one the other day at 4200ft went with a 140/40 with one shim and said he felt like he was dumping gas in there and was sure he could use a 138 main with stock pilot jet. 142/42 seems to be common, but I'd like to hit it right the first time.

I saw posts where some used larger jets in the rear, but a water-cooled bike shouldn't have that much temperature difference front to rear, should it? Especially since the rear has it's own water supply. One guy in Florida went with a 145 main in one of the carbs and another had a 42 pilot with 140 main up front, 143 rear.

Suggestions, anyone?

If youre running a stock, baffled exhaust, should be no reason to rejet...you might need to richen up the carbs screws some.
Rejetting is usually only required when you run very unrestricted exhaust.

I'm not sure I agree with that statement. Sexy is a very relative term...some guys think a woman with the body of a 12 y/o boy is sexy and some of us like some curves. Wait..what were talking about again...Oh yeah...JETS! So I have the 142/42 with 2 shims under the needles and I have my mixture screws turned out 2 1/2 on the front and 2 3/4 on the rear. I'm pretty much so close to sea level that if the tide comes in I'll get wet. Runs great and I'm still averaging around 46 mpg. I ride mostly highway to work at 65-75 mph.

Sounds like I should hold off and read the plugs for a while. I'd hate to spend extra cash just to make it run too rich.

Highest point in the state is 4500ft, and a three hour ride, I may never make that trip on the bike. Hills around closer may top out at 1500-2000ft, but the river valleys are all near 600-650ft.

Was close to buying 142/42 jets, but it looks like - low altitude+stock pipes+ear shave = no jetting, possibly.

I did find some aftermarket mains for $2.95ea. and Keihin mains for $3.99.

Keihin Pilot Jet $4.99

Thanks for the input, may have just saved me from screwing up, I didn't think it would go at all without jetting.

Deviate, I didn't see your post until after I posted. Hmm, so now I'm undecided again. lol

I was looking at PJ too, but their site and a couple others loaded up all scrambled so I moved on. Kept the links.

Ceal, I got them on Ebay, new in opened box, make offer, so I went $15, $17, $20. Looked like I was only getting three chances at making an offer, so I jumped to $20 and they accepted and paid $5 shipping. Ebay didn't submit my offers until I hit $20. First time using that feature.

The other PKs on Ebay are running $30-37. And these have chrome ends instead of black plastic.

Going by the old posts, I can let the filter bend slightly or shim up the rear of the gas tank, but not as much as with K&N.

Edit: PS, curves are a lot more fun!
