Have a 75 CB200 with a very clean rebuilt engine, stock all the way to the airboxes. I was thinking about taking off the mufflers that I have and just running the headerpipes for exhaust since Im havin a P.I.T.A issue with one of my muffler mounting brackets lol.
Question is: Is this a change I would be able to do without pulling the carbs off to be rejetted, or could I run the headerpipes, and just make some adjustments on the carbs and be good, maybe even get a baffle to put in the pipe? I basically dont want to have to pull the carbs and have them rebuilt if I dont have to because I plan on getting new carbs in a few months anyway. Thanks, Cheers!
 
Far cheaper to fix a mounting bracket than put a new piston in after you hole that one.
 
Gotcha.. What type of mods would I be looking at if I wanted to run an open drag style pipe ?

Sorry to bust your balls, man. You would need to rejet your carburetors and that's a topic broad enough that it can't be answered without your bike, a box of plugs, and the distinct possibility that before you got there you would lose a piston.

I would suggest you do some heavy reading on carburetion and exhaust, and that you fix your muffler mount. :)
 
Ya. Just giving you a hard time. In all seriousness though, open pipes are for race bikes. Not small displacement street bikes. You can switch to some bstter flowing aftermarket mufflers, but you need something there.
 
Haha, its cool man.. I would be disappointed if you guys didnt say something to bust a little.. I know its a wide open question.. just thought I would shoot it out there.. Saw a dude with a CB200 running a header pipe setup with some aftermarket baffles he had stuffed in there, seemed to work well and I had never seen it... so I thought I would ask... thanks fellas. Cheers.
 
Well... You could run a baffle. But, you'll never really get the bike to run "right". You'll lose power somewhere, and the cb200 has very little of that to spare.
 
Ya, I agree. Thanks for the input fellas... Im either gonna look for a scrambler setup or fab some headers around a nice scrambler style muffler setup.. you guys know anywhere that has decent ones off hand ?
 
There are Several scrambler pipes on eBay and the same sets come up over and over because they are asking a premium for them. We got our pipes on eBay and lucked out and found the muffler at the motorcycle graveyard hunting for 4 hours. Pipes are in very good shape but the muffler baffling is gonna need work since it is rusted out...There are several tutorials on DTT about the science of pipe tuning and jetting your bike. Run it lean and burn a piston. Read, Read, Read. The DTT members are true gents and have saved our pocket books on many occasions. Go to each of the forum sections and read. The one on how to build a cafe racer should be a book in its own right. Cheers and welcome to the dtt and cb200 family.
 
What's the problem you have with the mount anyway? 9 out of 10 times it's easier/cheaper/better/smarter to fix the problem than to start another one ;)
