Bonneville America Forums Forums Technical Forums Performance Mods Jetting problem

Hey Folks,
I tried to change jets today, couldn't get the new one in {only tried one side} It seems to me that the main jet and the "jet holder" are one piece, I looked at it under a magnifying glass. At any rate if the jet is a seperate part it is certainly not going to come out clean. I boogerd it up but the bike still runs O.K. Seems I need more parts.
What is the proper name for the jet holder? Is it hard to find?
The bike is a '03 BA with the stock CVK Kiehns

You're supposed to hold the holder with an 8mm wrench, and take the jet out with a screwdriver.
They're not 1 piece

Here is a picture of the process from Dinqua's site

It is OK if you bugger up the old jet if you are not planning to re-use it. Put an 8MM wrench on the jet holder and you can then use pliers to break the stubborn jet loose. Might have to either pull the jet holder out with the jet or pull the carbs to make this job easier. If you pull the jet holder out be careful not to lose the jet seat.

Ian, what does the jet seat look like cos I've had to change my jets by pulling the jet holder out with the jet? I'm certain I didn't lose anything during the process but I'm just curious for future reference. Is it an O ring or something? cheers mate.

John, is this what y'all are talking about?



Now this is where the o-rings are...

Yeah Moe thats what I'm talkin' bout. The jet is in there real good and tight, it looks like its one piece. I had it in a vice and started chewing up the jet when I decided to stop. Didn't see any jet seat. And I'm not sure the jet holder appeared on BikeBandit's exploded veiw, I'm afraid to booger it up.

Yes Jim, that's the one. I just wasn't sure what Ian meant by the word "seat" and thinking he probably was refering to the collar.

Yeah so every time I replace a jet I just get the 8mm spanner out these days and undo the holder to access the jet that way. I've always made sure the coller wasn't lost or anything and then just unscrew the old jet out easilly.

Yep the collar. It shouldn't fall out but I have read that some on here have experienced that.

I'm still looking for the "jet holder" online. I find reference to needle jets but no good descriptions. I just want to make sure I can get that part if I end up damamging the ones I got. I gues bikebandit's needlejet might be the thing. I'll soak the parts in somthing before I try taking them apart.

Properly labeled in parts books as follows:

collar=needle jet
holder =needle jet holder
main jet=main jet

I got it done. I took the jet holder back out, soaked it in some solvent, a drop of liquid wrench and the jet came right out. I tried the ther carb and it all came apart as easy as could be. Of course its raining here today so I can't go for a ride....

Here's my long story of what I did to the bike after reading here.

I drilled out the first baffle, did a sloppy job, just don't look up my pipes.
I rejetted with the carbs on the bike. This saved me no time. There are eight screws for the float bowls and seven of them are easy to reach. That last one is a pig, I tried every sort of tool to get it. How I managed to booger it up without ever getting a good grip on it I don't know. It finally came of with a tiny locking plier, a cheap copy of a vise grip, its about the size of a car key. An awful long time on one screw. Now that I've replaced to bowl screws with allen heads its easy enough to remove them.
When the jet holder came out with the jet I was worried I was messing somthing up, I didn't want to proceed without knowing where to get another part if need be. Still ain't sure.
So now I'll put in the K&N filter and pull the snorkel and see if I can tell the difference. Maybe next year I'll drill another baffle and jet again.
Thanks all,

I have got some new staintune pipes and in the process of changing jets the collar fell out cos I couldn't get the jet out withouth using the 8mm wrench and getting to the jet that way.

I pm'd Ian (dog) and asked him what end goes up first as they are different and he sent me a picture of the parts. I have enlarged the collar pic and it looks like the end that is not as wide as the other end goes up first.

Has anyone else had to refit the collar, and if so can you confirm what end fits up first? thanks to anyone who can help

I just had Ed (oldroadie) pm me with the answer after having a look at his spare carbs and the answer is the narrow end as I suspected. I'm going out now to try and fit it and hopefully all will be good.

Yes, the narrow end fits so that is sticks up into the carb throat a bit. Just went through the same thing with a K-saki carb.

Thanks Troy. I fitted it ok and my new settings for the Staintune Pipes and looking good at present.

I actually thought maybe the collar wasn't fitting into its spot all the way up cos I couldn't get the bowl on. Turned out where the floats pivot there is a wire hinge which had moved sideways, hence my problem. I just pushed it back into place and voila, bowl fitted.

Geez it had me stumped for a good while though.

All these little things I learn along the way but I'm never disappointed by the help of my triumph mates here.
