V&H SS2R on GS700E

[Gargoyle081]

Well for those of you 700E owners who saw my posts in the "wanted" section of the site...Yesterday my SS2R exhaust got here.I didnt have time to stay home and get too far into it but I did manage to slip out in the garage for a few minutes and get the stock exhaust removed...and kinda take a look see at what may have to be done to make it fit.


Right from the start I could tell the stock exhaust bolts werent going to be of any use so I took note of that. To mount the collars that come with the SS2R you need much shorter bolts and I picked them up (M8 1.25 x 25) and some anti-seize on my way home from work today. The collars fit extremely tight into the header tubes, to the point where even after coating the inside of the tubes with a little grease(recomended) it was tough to test fit them. I ended up using some 800 grit sandpaper on the inside of 2 of the pipes to make it a little easier.


Heres where the fun part starts....Once I was sure I was going to be able to get the tubes over the collars when they were bolted to the motor I bolted them up and started to fit the header onto them. Three of them went on nice and tight over their respective collar and o-ring. The one that goes to I believe cyl #1 (left of the bike as your sitting on it) wasnt lining up.


I took a look around to see what was stopping it and noticed that down low it was contacting the bolt that connects the oil cooler line to the pan......Now Im at a bit of a stand still. Everywhere else the header hugs close without worry of contacting anything.

I fitted an SS2R to my sons GS1100E.

It required machining some new collars (I'm using that term to describe the plates with 2 bolt holes that fasten the header to the exhaust ports). This was needed because the hole spacing was not the same on the GS and the GSXR.

I also machined new sleeves (these being the inserts that this header uses to mate to the exhaust ports. This was done because the exhaust ports on the GS and GSXR are not the same size.

I also fabricated new rearsets since the stock footpeg location will not allow the SS2R a proper routing. Next came a new rear fastening point.

Anyway, I think it came out well and the look (to me) is better than any other exhaust system I've seen on this bike.

Lots of other mods also besides the header.

Good luck. Possibly the GS and GSXR 750 models are more closely related.

I see. In doing this I didnt have a problem with the exhaust ports being the wrong diameter. As you worded it..The sleeves fit into the exhaust ports nicely, and the bolt spacing in the collars that hold them to the motor are the same as well...if I only had 1/4 inch more room down by that bolt I would have no issues besides fabricating a rear mount for the canister. So close to a perfect fit. I dont even think Im going to have peg issues as the mid-pipe stays low and only angles the canister up at the end. Not sure how I can go about solving the problem..Any suggestions?

Edit: I actually just went out and slipped the header on( it leaves a 1/8 space before entering exhaust port and I set the midpipe and can up to it where it will go and I will have absolutely no clearance issues once the ploblem at hand is resolved. Midpipe and canister will run perfectly under both stock pegs with ample room for brake pedal operation. Then I just need to make a hanger.

Would grinding down the head of the banjo bolt help? As long as you can still get a wrench on the head of the bolt it should be okay to grind it down some. You won't lose much oil by pulling the bolt out. You may also be able to double up on the exhaust port gaskets to force the header forward a bit. I did that with the Yosh I run. Your old exhaust gasket are probably compressed which compounds the problem. The gaskets can be had from Z-1 Enterprises.

BTW, thanks for being the guinea pig. You done all the 700/750 riders a great service by finding out they will work.

Obviously the GS750 and the GSXR750 are much more compatible than their big brothers. That's good news for your project.

BTW, that's a very nice pipe. You won't be dissappointed.

ok I may be able to get enough clearance if I grind that bolt down...maybe. I took a few pics(just with my cellphone) and Im going to post them in a few minutes once I send them to my email....so standby y'all

Hey, I've got a 750 I'm working on now too. I wanted to keep it pretty much stock and now this comes up.

[Gargoyle081]

Ok well sorry for the inconvenience but Im having a hard time posting the pics..BUT...never fail...I put them in my album take a look at the way the bolt is hitting and how far the pip needs to go to get past the o-ring and let me know what you guys think

Billy no problem with being the guinea pig on this one. Last week when you suggested the idea, you said it was gonna be a close one

[Billy Ricks]

It looks like if you take a little off the bolt you can get the clearance you need. If you double up on the exhaust gaskets you can get even more clearance. In case you need to know port diameter for them they are 42mm.

OK, it looks as if the pipe needs to be spaced out just a bit from the exhaust ports. Do you have a gasket in there now? If so, maybe stacking a couple (or more) gaskets might give you the clearance you need.

I think the sleeve length might have been one of the reasons (besides port diameter) that led me to machine new ones. If you have to go that route, it's certainly doable.

If I were you, I'd try stacking first, even if you're not going to do it on a running bike, just so you can tighten the header in place and see what other problems will pop up.

Ya beat me to it.

I guess I've always been a bit of a troublemaker. Back when I ran the '88 front end it was so short I hammered the bottom of the header on my Yosh system. When I have the extra cash I may pick up one of these SS2R systems. They really aren't priced too outrageously for the quality they are.

I'm gonna do some more mods on Matt's 1100 after this 750 is up and running. I'll take some pics then. I wanna rework the way the mono is setup. Do more of a Ducati type of plumbing (rather than a plate) for it.

To tell you the truth, I love this stuff.

That was a beautiful bike you built. Do you have any pictures of the finished bike to post up?

The '83 and up 700/750 models share the same port diameter so the GSXR based pipes fit without too much modding.

[Billy Ricks]

Well, you beat me this time. I'd love to see some pictures of the 1100 again. That was such a sweet job you did on it.
