weld some washers to some bolts.....put em in your headers right before the mid-pipe. I have a 9" micron with the guts ripped out and its all good for me. stock setting for the fuel mix screws is 2-1/4 turns I believe.....mine with the stumpy exhaust is all the way closed and I still pop a bit on deceleration. Hope that helps some.

All the way CLOSED!?!?!?!? That means no fuel at idle.....how is your bike even running dood??

Those washers don't do doodly squat other than look like a complete hackjob.

How does restricting the exhaust flow with a muffler benefit me more so then basically a straight pipe besides noise? If I can adjust the pilots adjustment screws properly then there's no reason to fork out more $$ to get a muffler.

Engine needs a bit of backpressure to run properly, it's how the heads and valves were designed to operate, especially on bikes designed with a 4-1 system. Power wise, and runability wise, you actually LOSE power with a straight pipe. It only sounds faster because it's louder. True story, and the Dyno can prove it. Pilot screws won't adjust for straight pipes, you will need new jets at the very least, different cams to make it right.

With the proper muffler you actually gain HP over straight pipes.

The muffler will make a lot more power than having washers restricting the flow.

Words of advise that I would take.Streetfighters are cool looking
But once you get above 70 miles per hourWhat a fucking joke

Really?
It's louder if you completely remove the header.
Then it would be the coolest ever.

I guess it's "live and learn" kind of a thing?

It's more than just power you run the risk of having issues with. If you run too lean you can potential burn up your headgasket and other issues as well.

You also don't really understand how little the fuel screw actually adjusts. He's a good chart to show you from barely open to all the way open what pieces of the carb affect what. To ruin the surprise now: trying to fix the carbs with just the fuel screw is the equivelant of trying to fix really bad meat with salt. Long before you fix the flavor you have too much damn salt.

There isn't really a jet kit out there for this either. You're just going to be ridiculously (and most people would say "stupidly") loud and run the risk of damaging your engine and you will have notable compromised power delivery.

Well when you're on your first bike, first fighter build, first exhaust mod, there's plenty of room for mistakes and learning so you dont have to be a dick about it

Thanks to everyone else for helpful info, I did not adjust the pilot screws and will most likely be putting the yoshi pipe back on

Well there was just way too much going wrong to even start with any suggestions.

So I chocked it up to a "live and learn" thing.
Go do whatever it is YOU want and learn from your mistakes.

I've built my own bikes. Some worked and ......well all of em worked.
But I'm sure I did some things others would have scoffed at?

Wasn't being a dick. If you took it that way?, that's OK. You are entitled to your own opinion.

P.S. I made that comment because I thought welding washers in the header would be just as stupid as removing the header entirely.

haha well I'm not about to cut open my headers to do that so were on the same page.

I'll just have to put the yosh back on and enjoy it

True, but we're just old and have made similar mistakes, probably some of the same ones when we were young and we're just trying to save you some time and heart ache by telling you what works. As long as you're having fun, ride on!

"Burn a head gasket"?!?

You might "blow a head gasket" or very possibly "burn a valve", but I seriously doubt you'll burn a head gasket!?

exactly.
Maybe it's just me? But after seeing so many bikes turned it to so called "street fighters" when really it's just a beat up bike stripped, painted flat black with an overly loud shitty pipe on it. It gets old.

I remember back in the day when some one would take a 500 lb GSXR1100 and change it in to a naked or "street fighter" if you will. Some of them were truly bad ass and they chopped the weight down to 400 lbs. It was a lot of work and some great craftsmanship!! But then a GSXR looked good with the motor exposed, most late model bikes don't.

Maybe it's just me?

Ride what you want. Just avoid building a pile of crap. Just because it stays on with zip ties and duct tape doesn't make it right. If you can't do a nice job? Get some help/advice. Don't be a squid and you will find/make friends with someone with the right tools and knowhow.

Done with my rant.
Love project bikes. I've seen Andy Cap's tool box

and he's done some great work, just look at that petcock bowl!! Holy crap Batman!!

P.S. Don't get defensive if someone says your thing (whatever it is) looks like shit! Opinions are like ass holes and belly buttons, everybody has at least 1.
Just take in the good advice and try to make it your own.

Wrong terminology. I should have used "headgasket failure". I've never experienced this mind you, and my statement on ultra lean leading to headgasket issues comes from discussions with nels on excessively lean tuned bikes.

I'm not sure.....it must be magic!

All I know is I've put over 2k on since I did the valve adjustment and carb sync. When I did the sync I turned the pilots all the way as closed as they get. Does that mean they are shut and no gas comes through? I guess not, hence all the miles I've put on since then........so we're back to magic I guess and thats' fuckin fine with me

As for the washers, hack job or not, there is a marked difference on how my cockroach runs with them turned 90deg so I guess that one will remain a mystery too.

I agree 100% there is a lot of mediocre shit running around with the label streetfighter. Put some thought into what you're doing and do it to the best of your ability. Just getting in there will help you learn. In the end your the one who is riding it and if your happy with what you have then Fuck em, everyone can eat a bag of dicks.

Also, I'm not a complete asshole and sit in front of my house blipping the throttle trying to blow their eardrums.

If you like the look of the small pipe coming up next to the rear-set, switch to a 900rr headers (not sure what year but i've seen it done) that gather into one pipe sooner then stock 2 headers and then get a welder to put the yosh pipe on with a tab on it to secure it. then the put your tip on that. That way everyone is happy, and you get the look you want in your bike. Just a thought.....
