Check out this frame. Its finally welded up and now its going to the powdercoater along with all the front fork hardware. Ill have more rebuild pics on the way soon. Im doing the 1048 overbore with lots of other goodies so im really excited; the ball is finally rolling again on this project.
 
Excellent job! I cant wait to see it after its coated! You'll have to keep us updated. (nice work area too, wish mine was that orderly!!)

The bracing looks cool but in fact is doing very little i'm afraid mate :o

sorry to be the bringer of bad news, i'm also wondering if the engine or an engine shaped temp brace was left in the frame while welding ?

Thanks but I know.

Thanks but I know.

Ive seen the OSS pics your talking about before I decieded on this style. I understand this might not be the correct bracing but Ive given this set-up lots of thoght. Since this bike is 100% street, Im not worried. Im going for a race bike, stripped look and am not going to use the side covers. I chose this layout so there is not a large hole in the frame to stare at. Im not an engineer or anything but I have a hard time believing that it will make zero difference. Also rember...the finished bike will be very light, between 440lb-460lb full tank. Even if it does not help I think it will look better.

Dont get me wrong its great advice. You are right on that set-up being stiffer. But wait till you see the finished project. It will be very fast (conservative power to weight ratio guess= 4.7); still handle well above stock (low-weight+suspension improvments); Stop great; and look fast as hell while staying unique.

Most bracing going on are for street bikes. Other then the drag strip these bikes don't see much track time these days.

Once you add on a modern GSXR front end, swing arm bigger tires with modern rubber the frame can't handle it even with a stock motor. Corner speeds go up, your flicking that bike faster then ever before and the tires and suspension stick so hard you can easily ride the bike beyond it's frame so a few frame mods keeps things tight.

hell, mines all over the place with the stock parts! :)


I guess it's all good if your going for a look and that's what's important. But if i'm taking the time to do all that I want some improvement over stock and I want it to look cool as well.

no gsxr setup

no gsxr setup

Youll just have to wait and see how it turns out; performance will definatley outshine appearence on the finished bike in most everything. I dont feel like Im making a performance compromise here just to "look good". Anyways the bike insnt even going to run a gsxr suspension setup or radial tires. So new radials are not going to highlight any frame inadeqacies. The bike handled great before, and this time Ill have the suspension dialed in better. So it will be fine. Honestly I dont even think my riding skills would even let me tell the difference between a properly stiffened frame and a stock one. I mean Ive never even scraped a foot peg, even on modern bike.
 
Thought I had a finished pic onlione, but I don't. Here's a couple from before powdercoat. All bracing not there yet in these photos, but you can see some of it.

Gussets on the head stock.

I'm sure you have coverd this, but just thought I would ask.

Not familiar with this frame and engine really, but will the engine be able to be installed with the top end, or will the top end need to be built up after?

I know the 83-85' 700/750 frame is different, but from pulling the engine on the 700 with top end assembled the front bracing would be an issue.

Just wouldn't want to build up the top end, and have to break it back down to install the engine. It would be easier to build up the top end afterwards assuming the cylinder and head will clear.

I'll take pics of all of it tonight and post a full layout tomorrow. It's 95% the schematic from Old Skool Suzuki board.

It would be great to get some detailed pics of the frame mods in case someone (like me) wants to copy them ;). The OSS pic is fine, just doesn't show a lot of detail.

TIA

I haven't tried yet (engine still off the bike), but visually looking at it, shouldn't be a problem. The gussets don't come as far down as the tank does (on the sides) and I could see daylight above my engine with the tank on. It may be tight, but it will go. There is a problem though and it's tank fitment (at least on the 1000G). I had to do a fair bit of denting inwards with a peening hammer on the tank to get it to fit over the gussets on the head. Also the battery box has to be removed and moved back about two inches for the cross members behind the engine. Promised several times, but swear a full pictorial coming.

Your frame looks like there will be plenty of room.

It was Suzukfan78's frame I was looking at with the 2 tube braces at the front.

Anyway, I have been reading up on this subject some to get an idea of what it will take on an 700-1100 conversion possibly later down the road.

We like pics. :D

That's why I used gussets on the steering head instead of tubes, no way tank would have EVER gone over tubes. I welded in gussets, then took a peening hammer and gave them a bit of inward curve.
