It seems like this topic has been beat to death, but I've got a weird part left over on my California model vtx that I'm not sure what to do with. I just got this bike a few months ago form Milwaukee and I'm trying to figure out what is going on with this CA model.

I've got cobra pipes and every time I decel, I feel like I'm getting shot at which scares the heck out of the nice women and children here in the Twin Cities.

I've read through a few sites on this topic and can't find much information about what specifically needs to be removed from the CA model.

Attached are some pics of what I'm working with. Please give me any facts and feedback about what the heck I have going on that you can. I'm getting more and more lost the longer I think about this. Thx!

That cylinder shaped object is the charcoal canister. That also can be removed when doing th PAIR mod on a CA spec bike.

Here. I think this pertains to a 1800 but it should still point you in the same direction.

I just did the PAIR valve removal on my 07 VTX 1300. I've got that EVAP soup canister in the back, but that picture looks like you've got a canister under the chock knob. Is that right? I took the PAIR valve off in accordance with the instructions here (mostly just to get it out of the way for valve adjustments) but did not remove any CA emissions as I could not find clear instructions on the CA 1300 and got busy with other stuff. The PAIR valve part alone for the CA model is the same as with the 49 state model. No differences.

I'm not sure if you figured this out yet but...

I just did the PAIR mod on my '04 VTX 1300s (CA model). The part on the assembly that is capped was the part that went to your airbox. Plugging that is sort of like disabling the PAIR system, but it could lead to condensation build up in the vac lines, resulting in white smoke coming from the exhaust. not a big deal really, but it's cleaner to do it right.

I started to remove the EVAP system, but I'm a little stuck. I want to make sure I pull the right hoses and cap off the right nipples on the carb and manifold, but I can't find any posts on that.

also, that hose the arrow is pointing to in the first image is the crankcase breather line that must be plugged back into the back of the air box

I never did figure out how to remove the EVAP can. If you do figure it out, please do pass it along. I'd like to get that thing off too.

Question PAIR Valve Removal - California Model 2006-1300C

Yea, I'm in the same boat. I've got everything removed except the evap canister.

I finished the PAIR mod and EVAP removal on my CA 1300 today (I also added Glen's A/F permanent adjustment screw). I took it out for a ride, and it seems to be working perfectly.

I posted my process at VTXOA (and due to incompatible servers and my general laziness, I'll just point you there).

If that doesn't work, I'll email you a doc.

Good luck!

I have a 2007 VTX1300C that was bought in Louisiana, i just finished putting on a set of V&H Cruzers. I fired up the bike, sounds good, but backfiring on decell and it's dark outside, so i can see it shooting a flame out the back when it backfires. I understand that my carb will need to be adjusted, but is there anything i should know or do before moving forward ? And will this harm my bike in any way driving it to see how it performs on the Highway and do all VTX models have the pair valve, as i have read that only the California models have them...Any and all help is appreciated, love this site, very informative, with lots of great people here..

PAIR is on every VTX is is an emissions thing, leaving it on the bike or removing it doesn't hurt either way.

Our bikes are liquid cooled you do NOT need to rejet for pipe changes, small tweak of A/F screw should be all you need.

You did remove old exhaust gaskets and replace with new right?
Your exhaust acorns are also possibly bottoming out before getting tightened properly causing exhaust leak which will cause backfiring and stuff.
Use washers under acorns or just replace with some normal nuts that won't look as pretty but they get tight.

Welcome to site you might want to put a thread in the intro section with pics when you can, we like pics.
