To pod or not to pod ? POLL

just wanted to get a tally of ppl using and not using airfilter pods.
please select the tip of filter you guys run.
cheers brenton

 

I'm running stock on stock.

To pod you will need to:
- rejet your carbs
- replace your stock exhaust

For perhaps a few extra horses. The XJ is already a fairly tuned engine. For the price you pay for the change-out ($500-700), you really don't notice the performance gain a whole lot, if compared you put on super-slick tires, and progressive springs for example. That would only cost you $400.

 

yeah , ive already got a 4 into 1 that came on the bike, it would also be nice to hear the intake more .

I've been watching the xj-owners@micapeak.com email list and most are saying that it's almost impossible to tune the bike to run with pods. The last to try now has a set of pod for sale as he went back to the airbox.

 

Its not impossible. My Seca 750 has K&Ns and a Kerker race exhaust (VERY loud) and it runs STRONG from idle to redline. But a previous owner payed to have the carbs jetted with a dyno and EGA. The only way to go now having tried it myself with my Seca 550.

 

yeah so if any one has got a 650 to run rite with the pods , then they could post the jet sizes they used to get others close. cant be that hard if alot of the older bikes ran them stock with pods .
any one got jet sizes for a 650 with a 4into1 ?
cheers brenton

 

if every body is having so much trouble with pods what about a system that linked up the carbys to a large single after market filter ? or is it only the bikes with yics that have the problem with pods ?

 

Tuning is fairly easy, just takes patience. It will tend to be too lean just off idle so just make the idle jet a size or two bigger. It might be too rich in the mid range and you would have to lower the tapered needle a notch but increase the main jet if it's too lean at full throttle. Of course it also depends on how restrictive the exhaust system is that you have but that's what I had to do on the 750 Seca.

 

thanks guys, well i brought the bike of some goof ball who ran the bike with out the airfilter in the air box . and the carbys that he put on where reconded ones of a 750 . so if the bike ran well with the airbox but no filter and a 4into1 , you guys think it will run well with pods on ? since i figure there wasnt much restriction before with no filter in the airbox ???
what do u guys think ?

 

yeah i wont be parking it outside , and i dont plan on riding in the rain. ill just drive my car instead lol :wink: thanks for the links to

 

just because you put on pods doesn't mean you have to put 4-1 exhaust on. It would surely help (all parts to work togeather as stated above) opening up the air side would then require more fuel,,(re-jetting) seeing you have a 4-1 chances are it is already jetted. Why do you ask? is it not running right? poor fuel economy? just want more power? just plain ole courious? little story.i have 1100 maxim,had stock box with 4-1 kerker (no baffles) stock jetts 112's for the 1100,used to rip my arms out of sockets at wot (really) took off stock box,total loss of power crapted out at like 5,500 rpm (used to hit 9,000 no prob) felt like i was on my 650 maxim..started playing with jetts, made it up to a 150 main,no good wouldn't even go 50mph. dropped back down to a 137.5 thats were i am at now,still a little rich plugs are more black then anything,so i will shot in a set of 135 this spring and see were it goes. Also raised my needle a small bit with a tiny lock washer that helped more then any mod i've done. throttle responce is XSellent milage went up a bit and runs good. Just want to get a tan plug and i'll be all good.But if i had to do it again i would leave well enogh alone and keep the stock box with maybe a good quality filter.

 

yeah well i just got the bike 2 weeks ago and i havent put on filters yet , but my stock box is wrecked and it had no filter in it. yet it ran fine. the bike is nearly finished and ill be able to try the filters out. i just dont want to spend any money that will be wasted. but i need to sort out some sort of filters

 

Brenton, I've seen the pod set-up and I don't like the idea of having to keep on top of cleaning them when they need it (you are living in a dry area, yes?) especially in a dry environment. The factory box is ok (need to put auxillary breather holes in it to allow more air to flow, use common sense to apply those) but is restrictive. I've always run stock and am happy because I don't have the issues with debris directly attacking my airfilter. The jetting issues are what worries me most about the swap. Ugg, I'm not fond of pulling carbs 3 or 4 times in a day. What a pain (especially if your boots are hardening up). I have converted a set of 650 carbs to a 750 application and the bodies are exactly the same, just the jets need to be changed (and they are easy, just don't get stupid with the screwdriver, a LITTLE tap with a hammer on the end of the screwdriver is all I have ever needed to free up a stuck jet). With the change your mentioning, I would run the suckers first and see what the spark plugs tell you. Without an air filter system, you have no idea what jetting you will need so address the air filter first. I would recommend that you run an aftermarket filter in an opened up airbox for the middle of the road approach to common sense and performance. You will have to rejet just a bit with it but it should be near to the all out performance you are after with a touch of sensibility (i.e. not having to worry about weather or dusty environs). If you are handy with the glue gun, why not take an old stock filter and refit it with some new foam, its cheap and easy. Just rip out the old gause and glue in the fresh foam, cut to size. UNI sells the 2X3 sheet of foam for about $14 US and I've rebuilt about 3 filters so far with plenty of leftovers for another 2. You can glue the edges of the cut foam together with clear RTV and just hold the edges together overnight (it is tricky but do-able). Minimal cash outlay with better than stock results. Good luck mate and keep the rubber moving! Rob.

 

yeah cool ill see what i can come up with
thanks

 

Here is a little info frome some knolage passed on when i asked. The reson for a air box on bikes is to act as part of the pressure equlizing throughout the cylnders exmaple a car intake all have the same filter or even if you run a dual carb and air filter set up it still equilizes pressre between all cylnders the reason why you want this over sepreate for each is the carb's like on our bikes are 1 per cylnder and theay dont stay perfectly tuned. Every year you would see that theay are not all the same from the heat up and cool down of the metal.


To make a long story short it's to help make the ware and tare the same for every cylnder think if you have pods the center ones dont get as much air because the ones on the out side would get some air pushed at them and so on. This is why theay dont all have different filters.


Now to tell you what i will run and off from what i told you ill let you think of why.. I will make a air box that will fit where the stock one is and put pods in it with a sorce of forced air into it at 2 points between the 1,2 and 3,4 pods to help keep them running equal.


For the jett up thing this bike is jetted up not sure what jets but i will know when i pick it up at the end of the month. after witch i will be removing the baffels putting a straight pipe in place of where the baffel was to keep the stock look.




P.S. it's all about looking stock untill you here it run ( that's my theory)
