Carb pods good idea or bad idea???

I'm new to the XJ1100 world, last one was in college, but I do have some experience with Mikuni carbs both flatside and roundslide versions. I will have to disagree, for the most part, yes they are tough at first, but after a while you get the hang of tuning them and what jets to look for. Once again, I'm a novice but absolutely love the aftermarket K&N style filters but haven't yet experienced them with my XJ1100.

I will soon be installing a Wiseco 1179cc kit along with the K&N style (pod) filters to let the engine get more air, also thinking about an oil cooler. Believe me, there have been many, and I mean many thrown screwdrivers and cussing carbs, but when you get them tuned in, it's a thing of beauty. Whatever one chooses, have fun, it shouldn't be alot of work and frustration to ride these bikes. Good luck

 

You can get this one in the Jap ratio.

It's got lower-face Idiot Lites.

Check Mikesxs (google it) he has alot of gauges and tachs. Make sure you know what type of tach you need though as there are 2 types. Oh i was also considering pods, not sure what i want to go with now. ill probably man it out and tune for the pods..

 

It's not a matter of flatslide vs. roundslide Mikunis, these are CVs.

CVs do not like an infinite air supply; they CAN be tuned to run OK but it will never equal the performance of the stock setup, trust me. I'm not talking about top end or blinding acceleration performance; I'm talking about everyday "rideability." With pods you will only ever be close.

 

I MUST HAVE GOTTEN LUCKY WITH MY PODS.I USED A 1.2 MM MINI DRILL BIT FROM HARBOR FREIGHT TO DRILL OUT MY 110 JETS TO 120 JETS, SHIMS MY NEEDLES WITH A 5 CENT WASHER AND COLOTUNED THEM. SHE IS RUNNING DAM GOOD. THIS SEEMED LIKE A POOR MAN'S ALTERNATIVE TO DYNOJETTING

I was also wondering about going to pods, this thread was very useful. Thanks everyone!

 

Hi I'm new to this forum and overall very new to motorcycles! I bought my first motorcycle a month ago which was a 1980 Yamaha xj650....I'm basically learning from step one and putting a good amount of hours on YouTube...asking people and websites....right now im inthe process of taking every thing down to pieces (all tthat's left is taking of the drive shaft so I can remove the engine off the frame to paint it which is a pain in the ass getting those bolts loose under the rubber boot -__-) right now I'm at the carburator taking it all apart andcleaning the ish out of it ....previous owner must of never cleaned them cause they're ridiculously gunky and full of rust....but anyways....they are clean now and even painted! Just waiting for the carb rebuild kit of the gasket seals and jet screws...I was thinking of adding air pods to my carbs as well just simply because the looks...but based on what I been reading I'd prefer to leave the stock airbox ....my question is this....is there a way maybe I can add the pod filters just for looks? I'm sure there must be a way maybe like cutting off the actual pod filter or something....also the exhaust is basically garbage lol I wanted to add like a straight exhaust to the bike but don't know if that would give me problems or do I need a specific exhaust? Any information is helpful and can't wait to begin this journey with the xj

 

Hold on now - you used "engine enamel, brake caliper paint," or a 2-part epoxy paint, right?? if not, that paint is gonna wrinkle and peel off in a month. You should also bake the paint in an old toaster oven, then replace the throttle shaft seals.

Never thought of that - just buy 2 PODS and fit them over the 2 outer intake boots. You'd have to fit them over the clamps so you'd need a size larger.

If the "collector" section is shot, you buy the $249 MAC system.
If just the mufflers are toast, you buy them off E-Bay when they pop up.
If you want to get creative, you buy "throw-away" Harley Sporster mufflers or 2 tractor mufflers, and fit them by having a collar welded on.

 

Thanks for the info! Yes I basically sprayed everything with rustroleum for now justto oprevent further rusting..thus is temporary till I buy the compressor I need and the epoxy I'm going to use
As for the pods yeah I was thinking only adding two on the other boots
Just didn't know if I attached them to the boots if it'll mess with the air/fuel mixture
As for the exhaust its basically just the mufflers that are beat up dented rusted and even have some holes in it lmao I was thing of buying the megaphone 4-2 exhaust but if I'm going to have to mess with the carburetor needles then Im going to have to think of another option

 

hello all! im working on an 81 650...
only problems i've had have been from the carbs.
first one poured gas so i readjusted floats when i cleaned them out..

went to pods because the stock rubber that went to airbox had shrunken a bit... i saw above that some suggested drilling the jets wondering if that would be the me=ain or pilot jet. drill from bowl side?

and as a side note..... i read here somewhere on the forums that the air/fuel screws were under a brass cap near the choke pin...... NOT TRUE so DO NOT DRILL THAT....

i almost (*&$&* myself up with that.....


air fuel on the 4x32 Hitachi is on the air side. two screws left is fuel right is air... correct me if im wrong but thought i would share that here two as i see a bunch of carb newbies like myself

 

If you DRILL jets you ruin them as far as ever putting things back to stock plus if drilled too much then they're just ruined period.

Better to REPLACE them since it's going to take some "doing" to get it tuned to run halfway decently with pod filters and an open exhaust.

The mixture screws were originally capped off at the factory; but a majority of our bikes have already had them "uncapped" long ago.

 

Sounds to me like you don't have stock Hitachi carbs. The idle air screw is on top next to the enrichment plunger and that's the only fuel/air adjustment screw there is. Maybe you're talking about the air jets that live on either side of the intake horn.

This is a diagram of the HSC33, but the 32 has the same arrangment of parts.

 

THAT IS INCORRECT..... The mixture screws ARE UNDER THE BRASS CAPS AND YOU MUST DRILL THEM TO REMOVE THEM SO YOU CAN ACCESS THE SCREWS. XJ carbs have the mixture screw under the brass plug that is on the top of the rear portion of the carb. If you have the plugs still in, you must drill them to remove them.. There are threads here explaining just how to do that.if the caps have not been removed, the mixture screws and passages have never been cleaned, etc.....

If your mixture screw are anywhere else, you don't have the right carbs on your XJ.
