1300S Carb

I have been have issues with this bike for a while, I have learned not to let just anyone work on this bike also, I had to drop my exhaust and install o rings because the one I traded my oem pipes with for the vance and hines longshots installed them without replacing or using o rings .


I read the great write up on cleaning the carb and when I saw the picture of the oem and dyno jet needles, I just realized I had a dyno jet needle the previous owner did, but never told me. I did some reading on dyno jet and apparently the lock washer and spacer washer are supposed to be on the fourth notch not the third, mine is 3rd. I guess this is why I get spit and sputter occasionaly and have lean/rich issues that i can't seem to even out. I may just tear down the carb and clean/inspect it while I'm there. My issue is is the fourth notch really correct? I have the stock air breather but with k&n filter and aftermarket pipes, my air breather cover has a rather large hole in it for some reason, looks professional cut, looks like a x in a way but more like an hour glass. When I can afford one, I plan on buying a new cover oem, wish I could afford a hyper charger, LOL!

So what setup should I set my carb to for this? I do have the Glen Devries a/f setup , its a cable that hangs next to the idle adjustment so I can adjust when I want. Here is a video from last night when it was running better though, tried to get video when rough, will try tomorrow.

I've moved your thread from the How To board to the 1300 Riders board where you will get help. The How To board is for threads showing How To do something.

Welcome aboard..
I would recommend you get a new Jet Set "Factory Pro Stage 3"..
The dyno jets are very hard to work with, although some have had success.
With stock cover and filter element you dont need much jetting at all??
The needle setting is done in a sequence when jetting..

Depends what the main is. If thats wrong the bike will never be right. You cant begin jetting at the needle, and certainly not by twiddling Glens knob.

With any jet kit, you start with the main that runs best at WOT. Then dial in the needle for best midrange. Last and leastly, the A/F adjustment.

BUT, its pointless to do any of that if you are changing intakes.
My advise, Blow off mothers day tomorrow (your mom, wife, or both will get over it) and instead use the cash to get your hypercharger and a jet kit, then read up on jetting and start from scratch.

You have a hole cut in the intake due to the K & N filter. With the K & N, you must rejet the carb for greater air flow. that's why you are on a different notch. You need a jet kit with instructions or a mechanic that knows what he is doing. I ran K & N on my 02 Suzuki Intruder 800. It made a big difference. My 05 1300 VTX runs very well with no Mods for carburation.

I would say you are starting from scratch. It will be the best policy IMHO. My bike hated the K&N until I did the scar and some A/F adjusting. It still wants more fuel. But I will probably go back to stock filter after I dirty this filter up some.

In your head is the answer, Let it guide you along

I researched the dyno jet, found instructions and according to what I read the spacer and lock washer should be at notch #4 from top for my setup, so I did this and it seems to be better. With the crazy weather here I have not test rode it yet. Will at first chance. But cold start idle on cold night or warm day I do not need my choke anymore, hesitation and popping in exhaust seems to be gone, but a good 10 minute ride is needed. Thanks for the replies everyone.

Took it out for a long hard ride, and I mean hard. No issues! That's all it was, move to fourth notch!
