I lost my WOT!

Excellent, go get 'em!

I wish my problem was as easy to fix. I can't lose my WOT cause I never had it! The PO of my 550 Katana (Kitty Kat?) put a V&H 4 -1 header and pipe on it but never rejetted. So I've got nothing after 5K RPMs until I fix it. It's frustrating.

I've never done this kind of work. Can I adjust the mains or do they need to be replaced?

Are you using the stock airbox or pods? Get a Dynojet kit for the easiest, best results.
 
THe needles are more important than the mains when rejetting for a pipe and pods. The dynokit is the right way to go, it works out better. Some on this forum have gone 17 pages of threads trying to do it with stock parts and it never worked out.

I totally agree. :-D

Stock air box. I was looking for pods at first because I couldn't find parts for it - it was missing the top! I was steered away from them by someone who tried on their 550 and gave up because they couldn't get them working right. I finally found a lid. I've since replaced the filter with a K&N.

Would it be worth trying to get pods to work? It'd be sweet to get a little extra out of it, since I do have the 4 into 1 headers and pipe. But it is only a 550, I don't expect too much.

I'll order the kit next paycheck, $125 is a little much right now.

Ouch!

What brand of pods did your friend use? If you can find K&N pods for your bike, go for it and get the stage 3 jet kit. Just keep in mind that the jet kit assumes K&N pods specifically, YMMV if you use another brand. If you're keeping the airbox, get the stage 1 kit. Either way, follow the directions in the kit closely and you shouldn't have issues. I did the K&N pods + stage 3 kit + 4 into 1 on the 1000 and it runs great.

In my opinion , no. The most you could hope for would be 3 or 4 horsepower and that is not noticeable on a 50 hp bike really. Lighten the bike up by removing the centerstand, and a few other things, to shave 30 lbs off and you'll see a differnce.

So, if I stick with the stock airbox and Dynojet doesn't make a stage 1 kit, what should I do? Buy ithe satage 3 kit and try to make it work? See if I can adjust my stock needles and mains? What?

It really seems like a main jet issue, since I only have trouble when I get into it's range.

Have you done plug chops to see where your jetting is at as-is? It's probably a bit to a lot on the lean side right now if you haven't richened it up for the pipe. A stage 3 kit would make it much too rich unless you also use the K&N pods.

This is why I am not a fan of pods and pipes. There are two ways to approach this.

1. Find someone tht has a similar setup and frankly copy their method. It may involve some testing but you need to start somewhere.

2. Relentless testing with high speed runs and plug views. This means going 75 mph, cutting the engine, and pulling over to check the plugs. Raise needles, then goe up a main jet size in each carb, then raise needles one step at a time, until you get a nice tan plug color. PLan on taking the carbs apart 10 times to get it right.

CV vacuum operated carbs are a real Hillary since they are more sensitive to the air load across them than VM carbs are. The slides and needles are operated by engine vacuum and can be very tempermental.

It also goes without saying that you need manifolds that are airtight, newish plugs, good compression, even compression, good fuel flow, and proper valve adjustments to do this right. If these issues are not sorted out retuning the carbs will be a real chore.
 
FIXED!!!\\:D/

I put the un-oiled filters back on and went for an all-out ride down the road. She pulled hard all the way to redline in all 5 gears.

So lesson learned! Don't over-oil your K&N's!! :-D
I've been trying to tell people for quite awhile how easy it is to over-oil the filters with the bottle or spray.
The K&N spray oiling instructions say to make a pass per pleat. That will just get you a wet filter and you get to do it over again.
From about 4", I make a quick pass for every 2 pleats with very little overlap. Works for me.
