Thanks mate I don’t this bike will be out in the wet weather but I would like to repair it but if it’s not possible then I might have to block it, I can’t seem to find where it drains in the recessed petrol cap tho? So no petrol is actually meant to go through it?
-
I’ve been modifying my tank over the wknd and after cutting the some of the bottom out I noticed I had to cut what I think is a baffle but after cutting that out I sliced through the overflow pipe that runs from the petrol cap to the bottom of the tank? I’m not sure if you actually need this or not so thought I’d ask? Could I remove it or will it need repairing?
I wasn’t sure if they use these on like custom chopper tanks or not.
cheers

Thanks Swiss I appreciate that, I'll get a few more links more to be on the safe side, seems cheaper to buy the bits individually rather than get a kit.

Hi I just wanted to ask if anyone knew how many links in the chain of a gsxr 750 1990 there are? I'll probably get a 530 pitch chain so I'm not sure if changes how many links I need.
Also what are the stock sprocket sizes on the bike?
I'm hoping to order a new set for the bike and I'm not sure if the ones that are on there atm are standard.
Cheers

Thanks mate I'll check them out when I get some more shed time lol, trouble with electrics can be quite time consuming.
-
Thank you mate I really appreciate that, one less thing to worry about atm :-)

I wired up the tail light today and all seemed ok but a few loose cables touched together and made the flasher relay make some crazy noises and now the brake switches aren't working. I wanted to ask if there is a fuse for this or do they run through the flasher relay which might of got damaged when those wires touched together?
Cheers
-
I've just got to the part of the build where I pulled out the wiring loom and wondered where everything went before I stripped it all down lol, I did label everything and I think I've got it all in position and connected up, I just can't find or see any headlight relay tho and I'm worried I might of sold it with all the fairings maybe? Can anyone tell me where the original headlight relay is situated on a gsxr 750 1990 please? And if you can what it looks like? All I have is a bunch of wires labeled headlight but no relay connected to it.

Thanks captain I'll remember that, hopefully get it by the end of the year, if I manage to save up.
-
I might try and salvage this one then, it's not too bad and overall it's in good condition, I really like that seat, I always regret sell parts but at the time it funded the build so it seems like a good idea lol
-
Thanks mate I appreciate your help, looks like it's possible then, I really like the look of that bike and the tail suits it well.
Do you have any advice on the small rust patches I have on my tank? Would you treat them and use it or would it be a case of having to replace the tank?
-
Thanks captain I might have to try those spacers then if I hopefully get the engine, I would love a 1100 tank but they seem to fetch high prices on Eblag.
My tank has a two rust patches, I've tried to clean them up the best I can but one was so pited I couldn't get all the rusty bits out, would you recommend replacing the tank or do you think it might be salvageable? Cheers
-
I'm thinking about the engine on this build and was thinking about going for the b12 swap as it'll probably be cheaper and easier to get hold of than a gsxr 1100 engine, I have had some really helpful information on this before from everyone,
I wanted to ask if the engine will have enough room in this frame tho because the petcock on the tank is already quite close to the oil lines that connects to the top of the engine and I was just worried that if it's any bigger it'll be hitting the petcock? Any help would be great
-
Thanks again for your advice everyone, what would be the best way to pre heat? I have done a bit of that just practicing but I used a small blow torch and got a infared temperature gun to bring it up to a high temp, would a blow torch be suitable?
-
Thanks guys I'll give it a try, I'll make sure I prep everything well, yes I think that is my duty cycle so I'll make sure I let it cool down, I wanted a slightly bigger tig but they were so expensive I only just afford the smaller one lol
-
I'm going to weld up the subframe I've mocked up to my frame in the next week and just wanted to ask if anyone has come across any issues or problems when welding to the gsxr slingshot 1990 frame, I think it must be cast aluminium so I know that can be a pain sometimes, I'm not an experienced welder so I'm getting my friend from work to weld it up but he hasn't done much cast aluminium, any issues with frame warpage?
I've only got an r tech 160 ac tig so I hope it's powerful enough to get good penetration on the frame.
Cheers

Thank mate I really appreciate your advice and am very greatful, engines aren't something I know a lot of so am keen to learn what I can from this site and people like you.
I've got a good base point to go from now. Once I weld the subframe and find some suitable lighting I'll focus on the engine then.
Thanks @Fula28

Thanks @Fula28
I'm trying to keep this bike quite small and compact if possible. Thanks for your help with the b12 engine. Just a few more questions if that's ok.Would I need a bigger battery?
Would I need the starter and alternator from the b12?
What oil pain is best?
Would i use the b12 pick ups?
I've read a little about tuning the b12 like putting a dot head on and gsxr cams but I don't think I'll get into that yet.
-
Thanks mate, I'll start looking and doing some research on the b12 swap, might dry and sell a few bits and get some money up together for it,
what exhaust headers would you need? The b12 ones, I've bought the vance and hines megaphone for this project, not sure if it's the best performance wise tho.
Would i need a braced swingarm with a 1200 engine?
Here's a pic of it so far, excuse the pose I was just checking riding position

Thanks for your advice again everyone, I rode the stock bike before I started my build and it already had that annoying flat spot even in its stock state and with the way the subframe is going it'll look better with pod filters even tho I know it'll run not so well, it also popped into neutral a few times while I took it for that first ride so I'm not sure if that would be an issue that would need addressing?
I have a rf900/750 head in my wn so I do like a more torquey ride and wasn't too keen on the revvy 750 engine.
The 1100 engines seem rare to find on Eblag so maybe a b12 would be an easier option.
Does anyone know what year bandit would be best to use in my 1990 gsxr? Would pod filters be ok on the bandit engine and would I have to re jet the carbs?
I did the jetting on the rf900 and it's ok but not perfect.
I could sell the 1990 engine and I still have remains of the 750wn rotting on the floor in the garage so I could strip that maybe and sell the parts?
thanks everyone
-
Thanks again, I've had a quick look for a 1100 engine but on Eblag there isn't much about, would the 1100 be a simple swap of the engine or do you need the cdi and wiring loom?
there's plenty of bandit engines tho, are the bandit 1200 engines a good swap?
-
Thanks guys maybe that is the best option then, I guess with all the money you'd spend tuning the 750 you could buy a 1100,
would it be a straight swap changing to an 1100 engine?
I think an 1100 would he plenty for me so I dout is tune it much.
Are the dyna 2000 kits worth the money?
thanks for your help everyone
-
I've been thinking a lot lately about what I could do to tune the engine and get the most out of it and improve performance in any way I can, I'm still not at that point in the build but wanted to get some ideas and see where my money would be better spend on what parts.
I know I should probably just by a 1100 engine but for some reason I want to keep the 750 and just tune it up a little with what cash I have.
I was just after some ideas as I know a lot of you guys on here have plenty of knowledge on engines which is something I'm not too familiar with.
Is a dyna 2000 kit worth the money?
Would you bore out the cylinders and increase the cc some what or wouldn't you gain much bhp? And I've seen about installing busa pistons but I'm not sure if that's just on the 1100's? Are there cams from a similar bike that would give me a small improvement?
i found a tuning article online about putting a stage 3 kit on it? Maybe that would be a good start.
any help would be great.
cheers

6 hours ago, Gammaboy said:
No, no they don't. They bleed oil from the high pressure bearing feed circuit to the head cooling spraybar (which is lower pressure).
Thanks gammaboy I didn't realise that, I'm not too familiar with the engine side of things yet but I'll be trying to rebuild the top end on this bike hopefully.
Is it better to have lower pressure in the oil circuit?
How important is the petrol overflow?

Thanks everyone, unfortunately I don’t think I can get a good angle to try and weld it together and I thought about sleeving it but if it failed down the line all my time modding the tank would be wasted, I will have to remove it and be careful I think and inspect it now and then, I’m trying to do a tank mounted speedo but not sure if I can pull it off but I’m having fun trying lol.
i did think of brazing it but don’t have the tools, I’ll have to use por15 once I’m done too
