Any way I can quiet this exaughst down?

Here is my KZ650 I just got a few weeks ago. It is to loud for me and it makes poping noises.

I was wondering if there was anything I could do to quiet it down without changing the entire exaughst system and at the lowest price.

Is it possible I could add baffles or somethign to it?

Thanks alot.

I would take that huge megaphone off while i was looking for a answer. It looks like someone added a extension to the existing exhaust. If it were me i would cut the megaphone off at the first weld from the back and then find or fabricate a baffle. Roy

How quiet do you want it and do you like the current tone?

I'd say, if you want to do cheaply and you have any handy skills, make your own insert. That can be as simple as a perforated blockoff or as refined as a tuned length packed as tight or light as you like.

This is for sale on eBay right now. I don't know what his 'reserve' is, but you could use what you need (the cannister and whatever pipe you need, and then re-sell the collecter to an '83-84 GPz owner and get some money back from your investment. You could hammer the eBay guy with the fact that the collector seems pretty dented up...but what's that matter for your uses.

As mentioned earlier, the 'Trapp option offers a disc set up where you can add or subtrack to your suit yourself.

Good luck,

Bad Kaw, Sorry but I think you forgot to include the Ebay link.

Virli I would like it to be pretty quiet but anything that isnt obnoxious like it is now would be fine.

Thanks


Also any idea if this would work at all?
How about these?

thanks

I'll tell you one of the coolest fixes I've seen yet was on here a few months ago. I believe it was Riveroad (A member here) used a muffler he picked up at a tractor store to quiet his bike down. IIRC it only cost like $17.00 and it looked good.

Okay I searched and found the thread here it is.

:blush: ...heh, heh, heh...so I did. My bad. Here is the eBay item number: 160139144886 :whistle:

Takuma, nice to see another '80 F1! Yea, I would check with JCW or ebay and do some measuring. Cut off what is there and redo it. Running a straight pipe with a megaphone is not cool, Harleys get away with open pipes, we don't.

Welcome to KZr takuma.

Nice looking bike you've got there!


Almost any cannister (Kerker, Super Trapp, Mac, Yosh, etc.) can be made to fit on there to replace what the PO of your bike put on, so don't limit you searches to something that only fits a KZ650 or a Kawi.

What are your plans for the rest of the bike...Resto to original?....Cafe' racer replica?...Chopper?...Just get it running and looking nice?...???
I'm guessing that it runs fine since you state the exhaust is extremely loud?

Before putting any money into getting a quiter/nicer looking muffler, you might want to check into what appears to be a leaky head gasket. :S
While a new head gasket itself isn't a major cost to replace if you DIY, you'll find that there's going to be other things that will "mysteriously" need replacing: "Since I've got it torn down to this point, I might as well freshen up the rest of the engine by installing a Big Bore kit, performance cams, porting, bigger carbs, etc, etc."
There are a lot of members here who have gone through this exact scenario.
Not that this is a bad thing mind you. Just letting you know that upgrades are contagious, and often times pricey. :whistle:

It is my first bike so I really just wanted something that runs decently and I can gain experience working on it for a low price.

It has 6200 miles and I got it for $325. So far I cleaned the carbs, new spark plugs, replaced the coils and points, drained the old gas and put new gas in.

I got it running pretty nicely now just a few more things left.

Now I want to replace the back brake, oil and air filters, oil, and muffler, oh yeah and brake lever (My dad dropped it :S)

I think I am going to search around locally for a used one, My dad saw a muffler off a Yamaha for $5 at the flea market a few weeks ago. If I knew what I did now I would of got it. Any I hope to find a good deal on one that I can make fit.

RetroRiceRocketRider I was just wondering why do you think the head gasket is leaking?
