I don't suppose it's a major issue, but how many bhp do you think you have from the motor? Have you had it on a rolling road ever?
Looking very tasty anyway. Thumbs Up

Many years ago OB, it was 133bhp back then, which was all you'll get out of this motor with a 1230cc kit on it using standard valves.

It already has a ported head, high lift cams and heavy valve springs but still uses standard valves. You can go 1mm oversize on the standard valve seats but any bigger you'd have to have somes serious head work done.

I'd like to get on a dyno again at some point just to get an up to date reading.

Well, I've got this new cooler. RollEyes

http://i249.photobucket.com/albums/gg225/Quazi_photo/20140224_1146541_zps41f71fef.jpg

It is a fair bit larger than the original one and twice as thick, the actual increase in frontal area and capacity is still to be calculated.

Mounting the thing is going to take a bit of modding, I'll need to use an original bracket (of which I have a spare one smile ) and knock up a new bracket then weld that to the original bracket to fix to the frame. I have an added problem for the final fitting and measuring, I don't have the bike. Laugh

I managed to knock up a bracket last night (bare with me on this one) it may not end up looking like this, but it's a start. I've chopped the original bracket and tacked it on somewhere I think will allow the clearance when fitted to the front of the bike/frame.

http://i249.photobucket.com/albums/gg225/Quazi_photo/20140225_121034_zps3d4ca9b5.jpg

http://i249.photobucket.com/albums/gg225/Quazi_photo/20140225_121049_zps6e1177e9.jpg

There may still be some metal to remove and weld it up when in the right spot, but so far so good. Although it's steel it's not too heavy as it's thin enough to do the job.


There should be plenty of air flow through it for my uses, the original bracket stands off the back of the cooler, so there isn't too much metal in contact at the back despite it looking like it.
I like progress. Wink

Nothing wrong with that bracket once it gets a splash of paint considering it knocked up in the garage/barn Thumbs Up



I wouldn't worry too much about the minimal increase in frontal area as I have seen pics of you and you ain't a small bloke Wink

Guy Martin would be proud of you.
(However I think despite the gap (which looks like about half an inch) there's too much area blocking the flow. Unless of course you only need half the capacity of the cooler. Sorry to piss on your fine creative efforts, just trying to help Get your coat )

I know you are OB, no problem, it is appreciated. Fluffle

I have done the best I can with the flow through rate for time being, the cooler has to be mounted in the orignial spot as the old one, hence the reuse of most of original bracket. There is a gap between that and the cooler though, which would have the frame and top of the engine so the flow restrcition is there anyway. Given the size difference of the cooler from the original the effective area should be good enough to achieve what I'm after. Everything is trial and error anyway isn't it. Wink

If it doesn't work I'll chop some more off it and have another go with phase 2 smile Thumbs Up

I've finally measured the difference in capacity between the coolers, the new one is about 4 times the capacity of the old one, measurements approx' 100ml in the old and 380ml in the new, so we should end up with something near usable with no adverse effects.

Just twigged given the capacities that this is an oil cooler right?

Assuming I'm right for once have I also just twigged that 'that' 80's gixxer engine you have in it is the one I vaguely remember seeing 15-20 years ago in a big gixxer for 199x thats oil/air cooled only with no water in sight? think

No water at all, a quick history lesson so you're clear. Wink

1986 GSXR1100
index.php?t=getfile&id=21144&private=0
First generation of gsxr series and oil cooled motor officially.

1986 GSX1100EFE
index.php?t=getfile&id=21145&private=0
Continuation of the GSX series which then effectively gave way to the GSXR series, although continued on as a lesser known sports tourer, it all went a bit weird. smile

My engine is the latter, from the GSX range and officially "Air Cooled" despite there being an oil cooler fitted. The cooling was reliant upon air flow through the block (which has gaps between the cylinders) to reduce the engine temp of the bike. The "token" oil cooler was for standing still in traffic as a precaution for being such a large motor.

The later GSXR range turned towards "Oil Cooling" as the primary source for engine temperature placing the need for air cooling to be a secondary requirement.

The GSXR range then went on to be water cooled along with the masses and has been ever since.


The GSX motors are still in demand today and becoming very rare to pick up in any great condition with matching cases etc. Many Many of them have been used and altered/bored out/turbo'd and blown up that numbers are diminishing all the time. Despite this, there is still a very healthy market for parts and performance parts for these motors, there is even talk of Suzuki producing "Vintage parts" again due to the demand, what they end up being god only knows.

Thanks Q thats confirmed I may be slow but I'm not losing my mind Laugh Thumbs Up

I think the only time I really look at one of them properly when they were new in a showroom must have been back in 1987 when I'd have had my KMX125. I ridden it to bradford motorcycles and vaguely remember looking at one just like that 1986 GSXR you have pictured and someone mentioning it was the most powerful bike of the moment (something like 140bhp stock?) then in passing pointing out lack of proper cooling system Wink

Still, it must have impressed that 17 year old who'd ridden to Bradford motorcycles to enquire about the cost of a new exhaust to double the power of the KMX from 12 to 24bhp only to be told it was possible to relieve the extra power by simply removing a small restrictive tacked on washer approx 4 or 6 inches down from the header Grin

Ah the easily impressed/fooled youth. Laugh Thumbs Up

I very nearly bought an FZR1000 back then instead of this GSX11, it was the same price but would have been a different direction totally. Despite the FZR being the ultimate sports bike back then I was just smitten with the awesome grunt of this motor instead of the plastic covered tupperware on offer. Wink

Strangely, this GSX is now worth more than the FZR would ever be. smile

It was a different world of course, sportsbikes had only just been invented, it was very early on in their development, and still a bit too radical for the masses along with the costs!

Well, I should be out practising on Sunday, but I have a slight technical error..........no bike. RollEyes


Haven't got it back yet, so can't attend the weekend, a bit pee'd off about it all, but can't be avoided. My exhaust mate Dave has been very very busy with orders from OZ for some classic Superbike systems in Titanium, so naturally they have taken priority over my moped.

The pipe is only half finished at the moment.

I still have things to do with it when I get it back so time is against me also.


Shit happens.

Cheers Pecks, strangely enough I got a call from him last night, he's finishing it off this weekend, so i can go pick the old girl up on Sunday.

Not seen any pics of it yet, so haven't much of an idea what it looks like in the flesh. He did say though that the rear brake lever is a bit tight, as not only as the pipe diameter increased but he's tucked it up as high as he can get it. I'll have to have a look and see if the rearsets need moving about a bit or changing completely. smile
