got my 07 1300C about 2 months ago with only 4600 miles on it, so it wasn't ridden much to begin with and I'm sure it sat for a while before I got it. A little carb/fuel injector cleaner went a long way in getting it to run better right away. I decided it was to quiet with the stock setup, so I drilled out the pipes following the advice I found here on the forum and am happier with the sound now. 1300 miles later, it's starting to backfire/pop occasionally on decel and while cruising (I think this means it's running lean????). I'm sure that the carb is probably in need of tuning/rejetting. I am considering putting a Baron's BAK on the bike and figure it's best to do that and the rejet at the same time.

My 3 big questions are: 1. Are the intake and rejet truly simple enough that if I can follow directions I shouldn't be afraid to do it myself (not very familiar with carbs) and 2. Will I need to immediately replace the exhaust with a more free flowing system, or will the stock exhaust handle the air kit and rejet being drilled out? 3. On a side note, the front forks are really soft/slushy and I would like to stiffen them up quite a bit (I always rode sportbikes until now) - would I be better suited going to a heavier weight oil, or using a larger amount of the recommended weight?

I know that's a lot of info, and I apologize, but I am excited to see what this bike can really be and with December upon us, even here in Central Florida it's a good time to tackle these projects as I won't miss much riding time.

Thanks in advance for the help as I have already seen what a great community this is. :cheers:

the bak will work fine with stock pipes. if you get it order a factory pro jet kit from amazon.com. re jetting the carb is not hard there are several pics and how tos here is one i made http://www.vtxoa.com/forums/showpost.php?p=2727083&postcount=6
when you rejet give the carb a good cleaning when its apart. might want to do that even if you dont rejet and put on the bak


as for the front end i agree and to fix it i put in progressive fork springs http://www.directlineparts.com/product.asp?pid=4182&str=13

i also cut a new spring spacer 1/2" longer than the stock ones to raise the front a touch

If you do any re-jetting in the future make sure it is only with the factory Pro stage 3 kit and not the DJ Junk or you will actually be going backwards because the DJ are actually smaller.
Also installing Glen's permanent a/f adjuster would be a great improvement for any future adjustments and also will improve starting with no or very little choke (a bad thing).

Not starting a debate...just trying to clear up misinformation. The DJ jets are bigger than the stock jets. It's been proven over on the OA (not sure if it has been posted over here on the Cafe'.)

And the DJ kit is not junk, it's just harder to tune for some than others. Many of us have had no problems with it after tens of thousands of miles.

To the OP, welcome to the addiction. You'll love the BAK paired up with a rejet...it'll wake your bike up for sure. I did a write-up on the carb teardown, so shoot me your e-mail via PM if you'd like me to e-mail a copy to you should you decide to tear yours down.

Are you running high octane gas? The premium gas will cause decel popping. Switch back to 87 regular.

HUH....that's interesting. I have been running higher octane gas on the assumption that it would run better -especially while running the carb cleaner through the tank. will switch to 87 octane right away and see if there is any improvement. thanks

I agree on the 87 octane. If the bike is stock then it is lean on the a/f setting.

Welcome from Tennessee Dave and wishing you a great day. atriot:
Have you removed the PAIR system yet? The PAIR system will leak and cause the rich mixture while decelleration to backfire. I would first check for air induction and vacuum leaks then would adjust the A/F a little rich and see if that helps unless you just want to rejet. Wishing all well.

I'm certainly not hellbent on rejetting the carb just for the sake of doing it. That being said, not knowing the bikes history or how long it has sat around, a good cleaning seems to be in order. If I'm going that far, then I'm thinking that I might as well go ahead and rejet it - plus I have heard outside the cafe from harley people that I work with that a carb should be rejetted if you change the air intake. Don;t know if that's HD specific or just a general truth about carbs...

I will do some searching on the PAIR system you mentioned - I have seen that before in here...would it be a good idea to just do that mod as well while I'm in the carb??? :hmm2:

A carb needs to be tuned to the air kit you use not that you need to change jets.

Many times just an adjustment on the A/F and a shim to raise the needle is all it takes to wake the bike up.

Clean the carb first and see what is in it for jetting then you can make an informed decision.

I'd get rid of the PAIR system while you're in there. Normally, we'd say not to do a bunch of stuff all at once, just in case you have problems. But removing the PAIR system doesn't affect anything and will help get rid of any decel popping with aftermarket intake/pipes (even drilled stock pipes). You'll need to order some block-off plates, and I think VTXRosa sells the ones with dimples built-in so you don't have to drill off the screw head for the reed valve. He's over on the OA site, so if you're not a member over there, join up and then send him a PM.
