jets

I've got a 82 xj750 Maxim i'm rebuilding the carbs and wondered if anyone could tell me what jets i would need if i have drilled 8 holes in each side of the stock mufflers and i am going to put a filter on each carb. or would the stock jets be ok ?

 

Oh boy have you done it now :roll: the pod gods lay low on here and waite for someone to ask a pod? and they suck the life right out of the post, so bail out while you still can. he he he :lol:

 

what the heck are you talking about? i just need help with my question

 

HA HA HA HA HA!!!!!

If you need to ask, then you are not ready....

the stock jets will not be ok, btw.

How does the bike run now?

It's not that pods are impossible, it's just that to do so requires a Ph.D. in XJ's.

Your Doctoral Thesis is to get it running right with the stock configuration.

 

No pods. I command it to be so.

 

After alterations to the Intake and Exhaust you become a member of the Pod & Pipes Eternal Experimental Re-Jetting Committee.

You might find some configuration of Larger Jets will make the Bike run in a manner that you'll find acceptable.

Maybe not.

 

Nice lol

 

it was running ok but had a low speed miss,I put some fuel system cleaner in it and seemed to be getting better then all of a sudden at a stop light it studered and died and would not idle anymore ran ok at higher speeds but not at idle so i tore the carb's down and cleaned them up. like i said i've drilled out the stock pipes and would like to put pods on it and like someone to help me with my question WHAT SIZE JETS DO I NEED TO USE ?

 

Pod filters for the inexperenced carb tuner is a road you don't want to travel. Some have braved the rough and winding road to reach the end with sucess but most lay broke down on the side of the road and walk back.
You can do it but be aware that there is no set jet size for your bike, its all trial and error. You will be removing and installing your carbs quite a few times to change jets.
If this is your first bike my suggestion is to leave it stock for now and get familiar with riding first. Put your effort into having a safe bike. Save the extreme costom modifications till later.
If you really have to do it. A starting point is up 3 sizes on the mains and 1 size on the pilots.

 

I know the pod guys will get pissy about this post so lets make a disclaimer

Yes, some riders have had experiences with pods that are "successful" in their opinion.

Most of the people who try pods cannot get them to work successfully. Why? Because it is not what the bike is made for. Yamaha made well designed bikes. If the bike ran better with pods, don't you think they would have put them on?

It has been proved that pods actually decrease the performance of your bike.

Yes they look cool. But that is really all it is. I would advise not sacrificing your ridability of this bike simply for aesthetics.

It can be done (sorta). Yes, some have done it. Yes it is your bike and you do what you want. As mlew says, lots have tried and most are not successful. Cleaning and tuning carbs can be a difficult task until you know the ins and outs of it. Pods are going to make a long process a very excruciating process that may never come out to anything good.

 

this is not my first rodeo i've been riding for along time i just want to get the most out of the bike that was given to me from a friend and would like some help with doing so if there is no one that can help then don't reply with crap

 

I apologize if any of our advice offends you. We are simply trying to let you know what we have seen others suffer through and save you the time and headache. There are quite a bit of information here in the forums if you really do wish to go through with it.

You may have done lots of overhaul on carbs, but there are members here who own multiple XJs and this information has been tried and tested extensively.

 

thanks ravenz07 i'll leave the pod off i just thought it would help it run faster with the proper setup so even though i drilled holes in the mufflers i should use stock jets ?

 

You are asking a question for which there is no answer.

 

Well like those before you. There is only one way to find out. Get those carbs together, throw them on and see if you can make that bike run the way it should. These can be very fast bikes if properly tuned. In my thinking, I would think stock jets should be ok with what you intend on doing.

If you do plan on doing pods still, remember to keep your airbox in case you wish to go back to stock.

 

anyone know where a stock air set up for sale is? I dont like what Im hearing. Hey I got 4 new pods in the box Ill trade, any takers?

 

thanks for all the help i'll get back to ya'll when i get it back together and let you all know how it went

 

Well here is a bit of read on jets and pods, I know you said you dont plan on doing pods now but pods and jetting kind of goes hand and hand

skw1972, there is always someone about to put pods on haha, you just got to wait and call dibs on the airbox. http://www.xjbikes.com/Forums/viewtopic/t=33047.html I am not sure if the airbox is the same for your bike.

Threefingers, I would hate to deter you in one or another because of my opinion. I would really encourage you to do as much reading as possible so you can make an educated decision for yourself.

 

And we all love pictures around here!!!

 

See i told ya, did'nt take but minutes for the pod gods to jump on the band wagon. he he he :roll:

 

I have to say that if a very few extra MPH is what you are looking for then you ought to just go buy the bike you want because the pod conversion that you want will be a real P.I. T. A.!!!
As for drilling those mufflers.... why!?
You can probably find a 2-1 exhaust system but then you are back into the guess work game again! When you drilled those mufflers out you changed the way your machine breathed, now the carbs will need to be rejetted.
If you want to run the bike stock, you will find that these bikes are really fun and quick!
Note that I didn't say fast. If you want fast go get an R-1.

I know that this site is devoted to help others learn how to fix their bikes, but most here usually want that old girl to run like brand new.

Sorry and I really do wish you good luck here!

 

yeah I know I gotta take some pictures. I bought this bike from a guy with no air box, he put pods on it and never could get it to run right, When I took the carbs apart 2 of the jets was just layin in the bowls, ! stripped out and everything else screwed down all the way tight. plugs - soot black, at least not white or I wouldnt have got it, well yes I would have I always wanted one of these back in the day so 100 buck for her and kicking close to 300 on ebay now Im still happy, got a ways to go yet though. any body got a pic of what a carb is suppossed to look like? I was looking at chacals info overload and seen a pic, I think Im missing something! is there a "plate" inside the carb under the diaphram?

 

cursed are the pod gods!

 

If I remember correctly, there was a brass (?) I believe plate that is under the rubber diaphragm on the top of the carb. Underneath the plate should be two jets. One smaller than the other and must be put in proper order.

I am not sure if it is needed.


I would recommend not pulling out your jets. Certainly not the small tiny ones. Chances are you will strip them out as they are soft brass. Just make sure they are clean and not blocked.

 

yeah that plate is gone with the wind in my case, hope its not needed. I was "learn curving" and think its an anti tamper? lot of good it did! So those jets dont go "X" number of turns out? Im hoping other than that I can check valve clearences, bench sync, fluid test, colortune and ride. AFTER i come up with a stock airbox. all fluids are new, new tires, wiring, lights, etc already done. could use a front fender though and still need to do the fork seals. my gallery shows it red but shes about to be all blacked out with white accents and tank. any way im stuck on those jets, one is a #50 and one is #195 dont know if these are stock or not and where to set them. the are out, came out easy, its clean now, rack reassymbled and here I am hung on this plate and those jet settings.

 

Those jets just get fitted in there snug. Just dont overtighten. Just enough so they are in there.

I dont know if the 550 and the 650 are the same, but I do know this guy here has a new one.

I do not remember the jet sizes though unfortunately.

 

diggin it bro thanks
