Carb rebuild kit issue

[Jimmyshifts]

Hi guys,
I was cleaning my carbs when two of my pilot jets became damaged. So I figured that I mind as well order a repair kit. My carb has the recessed ilde scre and the kit that just arrived has the parts for the carb with the large head idle mixture screw. All I really need to get back on the road are the pilot jets but even they look different. Mine 2 holes then one hole pattern, the replace jet has sets of 2 holes all around. Where do I go from here?

Thanks!!

If you have the recessed idle screws you have late model carbs on your early model XS. So you have the wrong kits and need to exchange them for the kits for the late model carbs, and the jetting needs to follow the late model jetting as well, since you won't have the plugged idle jet either.

The number of holes isn't really important, do they have the same number stamped on them? If your old ones are 37.5, the new ones must have that same number. 2nd issue is make sure they are the same style, if you do a search people have posted a graphic of the 2 styles, one has the metering hole right at the tip, furthest from the threads, the other has the metering hole further down inside the jet.

If it were me I'd return the kits and get the right ones for your carbs incase you need the other parts later.

If you've got a motorcycle or "powersports" shop near by you can probably take your old idle jets in to match up and they will probably have the ones you need.

yammie prices

Just so youll know, hold on for a shock if you go to a yammie dealer for an idle mixture jet for late model carbs. They told me 32 bux plus for JUST one of them. Georgefix has one full kit for 18 bux. The mixture jets on mine were pretty well ruined by the time we got them out, we used everything conceivable inlcuding heat from a torch before finally getting them out. I am not sure exactly what it is that you need, but if its a pilot jet for late models, I have one of those in workable condition , its a 42.5, let me know the address, I can send it if you need just one.

Right pilots

make sure you have the right pilots or your bike will run rich no matter what you do. I had the wrong ones in mine and with the help of guys in here i got it running. It took me almost 3 years to find this out. I believe the right ones are BS and the other style is VM. Someone will tell you the right ones but i think these are. DX (Don) helped me and with out his advice [I] would still be running rich.

This illustrates the two types of jets. Ours are the ones on the right, BS30/96 type.


my local yam dealer charges 3 bucks each for jets. Not the cheapest but better then letting a nice riding weekend slide by waiting for parts.

I can read the #'s 47.5 off the side of my original pilot jet. I damaged two of the four pulling them out. I would gladly just replace just the two jets instead of the whole rebuild kit if need be. So where should I get them. the online stores I look at don't seem to distinguish which model I'm getting.

Thanks,

Jim

You can get them at Mikesxs.net, they are the right type, couldn't help you with the other websites your looking at. Also you will probably be able to find them local if you call around, then you won't have to wait for shipping. Just make sure you get 47.5.

You need to return those kits and get the right kits for your bike. Using those VM type jets WILL and I am telling you WILL make your life he!! till you get them back out fo your carbs. There are MANY cases on here of folks who have used those VM type jets and battled their carbs for months until the got the right BS type jets.

Talk to whoever you bought them from, and either get a refund or get the right kits. Best source I know for carb kits for our bikes is a guy on Ebay named Georgefix. He knows these carbs and bikes and will put the right kits together for you.

im just wondering if you have carbs of an xj
i think they came stock with 47.5.
some1 with an xj might chime in,
the stock pilots are 42.5 for the later model xs carbs.

does the enricher have a lever on the handle bars
or on the carbs?

Yep, I went to the local sled shop and picked up some Mikuni pilot jets and fell victim to the wrong jets because I didnt know the difference before hand. I just wanted to remind others there is a difference so make sure you get the right ones. Also, I wanted to point out that the thread in the Maintenance tech tip Blaine's XS11 Carb FAQ isnt quite accurate. Maybe it could include the above information so people know ahead of time? The ones I bought have 8 holes and are the VM style...

Hey Marshy, there is also a third style, the N151 style which has NO holes in the sides. There are several sources for mikuni jets, and some of them do not know these differences.

What size main jets did you take out? Are you going to reuse them because the mains in the early carb kits will be too big . 137.5

Thanks for the heads up, I will have to go to the yamaha dealer to get the right ones... I surmise the N151 style will not work? How many holes do the BS pilots have, anyone confirm? I dont have mine out yet...

Im not buying a carb kit or removing the main jets, Im going to change just the pilot jets, it runs very well after 3500 rpm.
