  1. Brilliant .. glad it's found a deserving home. Doesn't look very clean against that swanky white paint.
  2. Get the recently aquired white one recovered ... that might be a 3rd option?
  3. Actually it would appear the relief valve on the GSXR is to by pass the cooler and allow high pressure oil (when cold) to still flow to the filter. Same difference. With the bandit sump on the GSXR the oil can flow direct to the sump. With the mod, there is a throttled bypass direct to the filter which I assume will work at all times!
  4. I actually corresponds with a gallery that appears to be a return (perhaps from the filter) that drops into the sump - if it is not blanked off on my 1100M the oil after the pressure regulator that should flow into the cooler disappears up that channel - so oil doesn't get to the cooler in as much quantity.
  5. I'm just going through this in reverse with the Bandit sump on a 91 GSXR. As far as I can see there is a permanent bypass that has been throttled down on the bandit sump (with a jet or rather a very small aperture). However, there is a part of that return that does not match the GSXR 91 and 92 bottom end that appears to need blocking off otherwise the main feed through and just past the regulator dumps pressure straight back to the sump and there's very little flow through the cooler. I'm in the process of refitting the sump to check whether it cures the temperature problems. My view is that with your situation, you can just swop in the GSXR sump pre91, and the only difference is that there is not a permanent by-pass of the filer. This comes in when the pressure pushes the plunger back, and allows oil to flow through the by-pass. I assume this was there to protect against the eventuality that the filter is bunged up and creates a situation where oil doesn't flow well, and pressure increases.
  6. Yes ... I had the sump off today. I was baffled for a while with some GSXR based matching points (engine side) which turned out to be returns into the sump. However, on working it through, the blanked off bandit sump channel will no longer flow. This, mated to the GSXR, would have dumped pressure thorough that channel, and straight back into the sump. This together with the temp gauge I was running in that same oil gallery would of curtailed flow to the cooler - hence the increased temps. Instead the flow will go though to the cooler and also have a diversion past the filte via jetted down arrangement in the bandit sump. There will still be flow to the filter, and all should be good, This assumes I have read the oil flow correctly. Alll said and done it's the diversion route that is affected, and should that be affected and not working, then pressure would build if the filter is not changed (filter gets bunged up). I change oil and filter regularly .. so no issue.
  7. So after lots of checking and and pondering it would seem that the GSXR (91&92) has a relief valve when pressure becomes too high - like when the oil filter becomes bunged up). This allows oil to flow and by-pass the oil filter. The Bandit has no relief valve, but allows a certain amount of oil to by-pass constantly via a reduced diameter feed you'll see below the marked hole. The different circuits mean that the marked oil way is superfluous when using the bandit sump on the GSX engine. So it's blanked it off by tapping and using a home made grub screw and loctited. As without that the main oil pressure is being dumped back into the sump through the oil cooler line and not up into the engine - so noticeable with an increase in temperature measured by the Yoshi temp gauge. At least this is my presumption. We'll see if the mod works. The alternative doesn't fil me with joy as it means that the Racefit exhaust built around the bandit sump will no longer fit if I have to use the GSX sump. . I plan to fit a oil pressure gauge when I have a moment to check the oil is flowing correctly.
  8. @jonny1bumpand I were there Thursday and Friday. I wanted to stay over to have a gander, but had to be home - SWMBO had made it clear that 4 days of Cadwell was not on the cards.
  9. Looking at the 1100F schematic - the holes are the same!
  10. Purely to aid fitment of a 4-1 exhaust. That's the fallback position. Cut and weld the original GSXR1100 sump.
  11. So I've been concerned about the extra heat my 1216 has been recording on the yosh temp gauge ... I initially thought it was probably just the relocation of the temp sender (that's another story), but I decided to have a closer look at the part diagrams (see below). The gasket is the same ... but there is an additional oil way on the front right in the bandit motor which I assume does not match the GSXR motor. I thought I best check the bandit sump I've swopped onto the GSXR1100M (91) and there were differences. So other than the oil strainer and the pickups I had thought this was a straight swop. On closer inspection the oil ways are subtly different. Is this to be expected (i.e. don't worry about it) or is it ... you stupid plonker you needed another bandit sump from [insert year here)? Any help appreciated. The GSXR sump shown in the photo came off the bike. The bandit sump is the one I swopped in.
  12. Getting there. So service done, immediate issues sorted? Sounds like you just need to install parts on route, and fire up?
  13. The 41s will be good for top end ... but IMHO will be a bugger to ride everyday at normal rpm ... My 1216 runs FCR39s ... flowed head, standard valves GSXR1100M motor. 70ftlbs at 3.5krpm climbing to 90 ftlbs at 6Krpm and 147-150hp (clutch slip at the time) + 4 degrees additional advance 106, 110 cam timing (or was it 105, 109?) dyna 2000 position 2, 10K rpm limit Carbs FCR39 55 pilots 160 main jets EMP jet needles (clip @4) 200 main air jets 100 pilot air jets (1 turn out).
  14. Be wary of doing that sort of thing at Cadwell nowadays - they have a drive by meters around the track, and can black flag you if you are too noisy. Donington is the worst by far. At least the chaps at Cadwell seem to be reasonable about allowing close to 105 dB if you are borderline.
