POD filters without rejet

Hi I would like to put KN pod filters to my 94' xj 600. Can I do it safely without rejetting the carbs? What wrong can happen to my engine? thanks a lot.

PS. I bought the filters really cheap and I dont have more money for the carbs. As you probably understand I cant wait month more to earn money for the carb rejet.
Thanks

 

i dont think its detrimental to the engine it just may run funky

 

Rick came up with a possible solution to make pods work without rejetting. It Involved blocking the bean shaped passage to the diaphragm and drilling a vent hole so the air for the diaphragm isn't fed by the pod. Worst case scenario is you'd have to thread the hole you drill, put a short bolt in it, and then rejet. But if you already have the filters it's worth a shot... Post results?

 

NO, if the engine and carbs aren't fully "up to snuff" to begin with, you can easily create an engine-damaging lean condition.

Quite honestly, the "fix" Rick came up with may or may not apply to the semi-downdraught carbs on the Seca II, and since it involves drilling holes in the carb bodies, I wouldn't do it. Especially since it's only theoretical to begin with, hasn't been tested, and may not apply to that bike.

Better off to leave it stock if you don't have the funds to finance a re-jetting project.

 

Oh fitz where is your sense of adventure? Haha

 

I always get a sick feeling in my stomach whenever i see a new thread about this start...people have no idea what they're stepping in lol . My advice is search pod filters in the forum ... this poor horse has been beaten enough and I don't even know what it did to deserve it lol.

 

I don't mean to be rude, but four people on the other Seca forums already told you that it's not worth the effort, and that there is very little gain, yet you bought them anyways. You may have unrealistic expectations for pod filters. Especially on a Seca II.

Any person who says "I have pods and there is consistent pull through the RPM rage" has only (with lots of tweaking) gotten their bike BACK to the consistent pull it already had.

I apologize for cross-forum drama

I apologize for contributing to the discussion of the cancer of motorcycles that are pods

 

Kn normally cost more than 160 bucks. I can buy it a lot cheaper thats why im thinking again about it. I expect only better sound and the same hp.

 

Expect better SOUND? From "intake honk?"

Putting yourself through what you will be putting yourself through to run pods on that bike is hardly worth it for an increase in intake noise. And it will take some doing to get back to the "same HP."

 

Who ever fed you the BS that pods make a bike sound better has no clue how to make a bike run. Let alone sound better.

Here is what you can expect from pods. You show up at bike night and get into a converstion about your pods. The guy you are talking to keeps nodding his head saying yup, uh huh. All the while he is thinking what a loser you are and why is he waisting his time with you when it would be so easy to just take your girl and leave.

You want a better sounding bike?
Take the time to get it dialed in properly. Do the research necesary to know exactlly what the changes you are making will do to the bike.

Will the bike run with pods, and not rejetting? Maybe, but not good!
You will immediately lose hp due to the incorrect fuel mixture caused by the lean condition that pods create. Then you will start whinning about the carbs not being able to handle what the pods can deliver. After all the work trying to get the carbs right you will find that you now need some serious head work on the ports, valves, and cams. This all develops down the line to each part right out to the tip of the exhaust. If you make it breath better in. Then also has to be able to breath better out!!

Are you ready to invest a few thousand $$$ into ALL THE MODIFICATIONS that will be necessary to make the pods actually work correctly?

That is how you make a bike sound, and run better.

Anybody that wishes to tell me otherwise. Show me the time slip, or Dyno run readout. Simple easy proof!

My humble apologies to the true XJBikers. I step of the soapbox now. End rant.

If you do go ahead with it, keep all the parts so the next owner doesn't have to buy an airbox to get it running right.

 

Just one last thing.
When you sell the bike because it runs like crap. Remember that you made it run the way you wanted it to run.

I thought that it could be easier because that's later engine generation 4br (Diversion) and few things could have changed.
All topics I found are about older engine generation.

It's any difference? or the same problems?

 

If the carbs are CV type (Constant Velocity) they will have a slide operated by 'vacuum' (pressure differential). A less restricted air tract will have less pressure differential across the ports and vents that raise the slide.

To set it up properly will require changes to jetting across the complete operating range, not just the main jets.

It will run regardless.

 

The phrase that comes to mind is "re-inventing the wheel".

I along with many, MANY others have posted the results of installing pod filters on a CV carb equiped bike. You WILL lose power unless you install larger carbs so if $$ is an issue, send 'em back & get you're money back.

(see, I said it nicely)

BTW- it is funny though to see someone (don't take this personallyB-paw) get "caught" going forum to forum till they hear the answer they wanted to hear. I see it often but rarely does someone point it out.....

 

Don't put pods worst nightmare ever I'm currently regreting ever buying those stupid things. Ur opening a can of worms

 

Fitz, you're way off on this one. The better sound comes from the wicked lean condition. Ya know... that awesome mean exhaust note that sounds like burning valves. And boy howdy the slurps of rich mix on decell lighting off in the pipe. Sounds so great, like the motor is trying to escape.

 

Wait - there's other XJ forums ??

 

glad I'm not the only one that did that same double take

 

The only way I've ever seen pods work is through the beer can mod. I convinced my friend that we should try this on his 550 (not mine of course, that'd be stupid) and a few months later, to my surprise, It's running great, not lean, no rejet. do a search for this in the forum, looks pretty cool and works great. A true hillbilly hero came up with this.
