  1. Definitely sounds like a lean condition, which would suggest an air leak as Gix-er has stated. A good starting point regardless is to record your current carb settings. GSXR carbs have been used on your model with great success by many people over the years, so I'm sure someone can confirm if your jets and settings are in the ball park. The standard CV carbs can work well, I'm still working out some minor kinks with mine but I'm 90% there. Please note my engine is pretty highly modified and with a low restriction 4-1 pipe with very stubby silencer. So take this into consideration if
  2. Simoniz 'Matt Aluminium' Engine Enamel is good. Used on my 1100. Does have a slight shimmer to it but looks quite 'natural'. Done 1000 ish miles since painted and so far its holding up well https://www.getgeared.co.uk/simoniz-aluminium-engine-enamel-one-coat-tough-paint-spray-can-500ml?utm_source=google&utm_medium=ggshop&utm_campaign=ggshopbasic&gclid=CjwKCAjwzvX7BRAeEiwAsXExo1KM1AjA1PDuLGsSGfgobQq5n4PHXRz6UeUTWeD9NSrT3nJRPvrBuxoCogQQAvD_BwE
  3. I've got this set up fitted to my 750ET. I don't believe its a specific kit for the bike. Just a generic oil cooler, with hoses I cut to length. The only specific piece is the replacement oil filter cover, which is a CNC made piece made from aluminium, with 2 NPT taper threads to attach the hose connections to. Unfortunately I wasn't the one to purchase it so I have no idea where it came from or who made it! The 750 doesn't have the oil sensor in the center of the cases, under the carbs like the 1100. So I think this is the only way you can do it on a 750, as the 1100 kits wont work.
  4. Good idea, thats got to be worth a go! Never thought about that possibility with the needles either, pretty sure I have a spare set of 5C32 needles so I will have to experiment
  5. Made very good progress with the 750 and now have it running 99% perfect. The vacuum sync kit confirmed that the carbs were quite far out, and the bike ran noticeably better as the carbs came into balance. I spent quite a while getting them as perfect as possible. So to anyone else reading this with carb issues, balance your carbs first!! I have now changed back to 42.5 Pilot Jets, as it was virtually impossible to achieve any kind of sensible idle with the 45's. 2 turns out from closed seemed to achieve the highest idle and the low end response is pretty good. Now the interesti
  6. I should have mentioned that I already have a Ledar air corrector kit fitted. Good to know about the filters, that will save me some cash!
  7. I've not no, but I've just found it and read through it and it looks helpful! I'm getting a carb balancing kit tomorrow. I know I should have done that at the beginning, but I've been impatient and couldn't wait to ride the bike I'll get the carbs synced then follow the guide from there. I've also read that people don't seem to have much luck with the gauze style tapered cone filters like I'm running. I may ditch them for a set of foam filters instead, which will hopefully help with the flat spot.
  8. Just had a quick look on the DynoJet UK site and it does appear as though they do them. Not in stock and £138 though! I'll have a play and see if I can improve it a little. But it's not the end of the world if it isnt 100% perfect. I was more concerned with it being potentially damaging, but the exhaust tip colour is a very dark brown, and the motor runs well so it doesn't suggest its dangerously lean? Thanks for your help
  9. Yeah new plug, maybe had around 1 hours use. No this is after a 'roll into the drive and turn off' check. Standard jetting for a GSX750 is: 112.5 Main, 42.5 Pilot, 3.5 turns out on the fuel screw and a 5C32 Needle on the middle clip #3. So it's already a fair amount richer than standard. The bike rides well on the whole other than a flat spot at around 1/4-1/3 throttle. Could it be worth just putting more time on the plug, and performing some various RPM plug chops?
  10. I've got a 1980 GSX750 with OEM Mikuni CV 32mm carbs, Pod filters, 4 into 1 exhaust and cam/port work to the motor. Its currently running rather lean (see plug photo) Current settings are: 135 mains, 45 Pilot, Fuel screws 2.5 turns out, standard 5C32 needle on the 5th (lowest) clip. Where should I go from here? I was going to richen the needle but its already at its richest setting, what needles do I need? Shall I go higher on the mains as well? Any advice would be greatly appreciated!
  11. Wire wool and autosol is a good combination. Will bring it up to a polished finished while cutting through some of the heavier oxidation. Won't get it perfect but you should see a noticeable improvement. If that doesn't work then red scotch brite and WD40 is another alternative
  12. Only just seen this! For info.... 750 in black, 1100 in silver
