So I had the header off on my 750 yesterday while doing an oil change, and decided to check for the hell of it. It fits and doesn't touch the plastics. I still need to pull the belly plastics again and make sure there's no signs of melting, and I'll need to swap out the oil pan as I currently can't get the drain plug out, and it's backfiring on engine braking pretty bad, so jetting will need to be adjusted. Also the 4-2-1 sounds really weird on a 750.

I think I was told it was an 1100 years ago, but can’t remember. I’m guessing by the shape of the header that it was for a dual exhaust bike. Tempted to see if it’ll clear the plastics on a 91/92 750.

Thanks, I need to do an oil change on it later this week and I'll pull it apart while it's drained.

Yosh seemed to think it helped. If anything it’ll look really trick.

Thanks!

Checked and looks like Suzuki used the same part for at least 40 years now, any idea how to check it before I replace it?

So as I'm going to be working on the bike before restoring it to full fairings, I figure now's the time to fix my non working oil pressure light. Already swapped the bulb and the gauges/front sub harness. I'm guessing it's the switch itself, any way to test it while I have the have the oil drained from the bike? Are they the same on all the oil cooled bikes? Thanks

Yup, those were for air to the airbox, airtech still makes the upper fairing with the intakes where the mirrors would go.

I’ve got tubes!

Thanks for all the replies. Got a set in the mail coming from Canada that should be here soon. As soon as I get all the body work back on this bike, it’s back to repairing all the damage the thieves did to my 7/11 and no more talk of stock bikes.

This is a mostly stock 750 with pods on the carbs. The tube that plugs into the cross member on the frame and blows over the top of the carbs I always suspected was more for cooling the area around the carbs than anything. Airbox I’d think would be drawing from the cooler air around the rear wheel/battery area. But like I said, it’s been years since I’ve ran full plastics.

Thanks, suspected as much. They can wait for the time being then.

Putting fairings back on to a GSXR 750 for the first time in over 15 years and it's kinda weird. Trying to remember, did the air intake pipes from the upper fairing do anything other than help cool the area around the carbs? This is a 750N(us market, same as the M), and the last time I ran fairings was on a 750J with flatslides and I honestly can't remember if I still had them or not on that bike. There's a few on Eblag for about $100 a set, but if not needed I'll skip them and focus more on getting everything painted to match.

Are these still available? BST38s off a 750N(us market). Recently started getting a lot of hesitation in the midrange that I need to sort out.

Yes, but they hang too low and I like parking on sidewalks.

Can’t get cams for them either. I’m just ordering a can from them. Hadn’t even thought about the short stroke headers not clearing the long stroke oil pans.

Just checked and the Hindle will fit my midpipe. Looks like I'll be ordering one of those up. Thanks again.

When I first looked I put in 90-91 GSXR750, and nothing came up. Checked again for 88 750s and the 1100s and saw those. Good to know someone is still making exhausts for old GSXRs. Thanks!

Hindle, nothing for old GSXRs anymore. Motogpwerks, all custom fab. Might just have to slap an 1100 or 1200 in it so I can use one of my big 1100 exhausts.

The mid pipe I think is a little tweaked too. I’ll check and see if I can get Hindle or Motogpwerks in the states, a lot of the euro brands are either almost impossible to get here or stupidly expensive. I bought a full Akro system from the UK like 15 years ago and it was about $2000 at the time.

Been checking Eblag constantly here in the states and there aren't any old exhausts anymore. Currently have a yosh system that's been chopped down way too short and I'm getting sick of how loud it is. I unfortunately got rid of all my beat up old 750 exhausts a few years ago because I didn't think I'd ever need them again. Does anyone still make anything that will fit the 750s? If I can't find anything by this fall I'll just swap a 1200 into it and use a old Yosh 1100 full duplex I have(I'll probably do that eventually anyway.)

Excellent, thanks!

Color doesn’t match mine, but I can have it painted.

Found someone selling what looks almost like a new old stock cowl here in the states, want to make sure it fits before I start haggling with him over the price. I've got a 750n, oil cooled here unlike the rest of the world. Here are some photos of the cowl, they're not sure of the year.

I think bandit 600 or early SV650 brakes fit, but the stock rotors are too small for them. You'll need larger rotors, probably easier to throw a newer master cylinder on it and braided lines or look into a front end swap.
