Hey, I was just wondering if anyone has any good ideas to increase the HP, torque or anything to get more speed out of my 1981 GS 650E. And what aftermarket pipes will fit on my 2 to 1 Headders.

1. Nitrous
2. Put in a 750 engine (don't know if you can do that in the 650 though)
3. On my 750, I can put an 850 top end--maybe you can do something like that with the 650?
Only nitrous would apply
The problem with 650s is, that most of them are Gs and therefore sport touring bikes
Not many speed parts out there for them
A 4-1 pipe and pods may yield a few HP, but not much
If you want more power, get a bigger GS!
Lots more cost effective

ACtually, if he TRUELY has a 650E, its a 550 bottom end with a 650 top end. Meaning, it has 6 gears. NICE, and rare as well... Just so you know, if its an E (chain drive) it might be worth a decent amount of money as GS's go if you return it to stock and make it look good.

My 650l has a Mac 4 into 1 and the jets were bored out. I've done some work to the baffle and I think its a pretty strong runner. My brother did the work to it in school and his instructor said its the strongest 650 he has ever had on the dyno there. I believe it was in the neighborhood of 54-56hp at the rear wheel. I don't think thats too bad for a 27 yr old bike with 20k miles on it.

Yup mines an E, chain driven bad boy. I was thinking of making it more custom. Drag bars, bar end mirrors, dual headlights and aftermarket pipes. This is all hopes of course. Anyone know if drag bars will fit on my bike? how do i measure if they will before i buy them? Thanks

If it's a bit of a rare GS I wouln't do anything but restore or sell it. Then you can get a bigger bike which would be a far better way to get the extra zip you want, but will never get starting with any GS650.

Drag bars do fit partially. I have drag bars on my 650G and they do hit the tank if you are not careful. I have heard you can't swap motors unless you go to a 550 because of frame size. There may be room to boar it out but why do it. You could find some can to fit onto the header with a little work. If you do that go get a header from the junk yard and save the original if its indecent shape.
A six speed would make for a hot setup but if speed is what you need it's not in any 650. I didn't want to fork out the cash for a crappy MAC exhaust so I made my own out of the stock and it worked well. I cut the pipes just behind the passenger foot rest and had open pipe inside a small megaphone and welded in baffles. Its odd but unique. Ill post a pic sometime. Depending on your build the 650 can be a small bike too. Im 6-3 and its a little cramped. Keep it or sell it but if you want a hot bike, step up to a 1000 down the road. Im keeping my 650 and picking up a 1.0L over the winter to build. Good luck.
