    Yes it does take it back to the tank,but you can't ever have just the ignition on to check anything without the pump running and it's keeping the floats pressurised with fuel all the time the ignition is on,I just think it's better this way,the pump,is running unnecessarily,same with the scavenge pump if it's on the ignition switch.

    That's easily cured by wiring the fuel pump relay via the oil pressure switch. Float bowls retain fuel for starting and pump will kick in after a couple of turns of the crank - especially on an oil boiler. Or just put the fuel pump on a separate switch?

  2. There is a tool to compress the valve in site enough to pick the shim out but you need to add one back in or the bucket will hit the cam face - not goo. Also run the risk of tool slipping and sending the shim into orbit! Best measure all, take cams out, measure shims - rearrange and buy what you need or find a suzuki dealer with a shim set and ask nicely if you can exchange some at a discount on buying new! Your lucky my M head came with no shims at all - Suzuki price x 16! Ouch!

    Hope 1.04mm was a typo LOL!

    so an intercooler is something I should look into..

    See if I can find something small enough.

    Thanks guys

    You don't know what boost you are likely to be using so an IC may be of no benefit and with IC's - small is not what you want. You want / need as big as physically possible a) to cool efficiently and b) to minimise pressure drop across the core. Sometimes better mixture / ignition control can minimise the need for an IC and unless you are running 1+bar boost for extended periods then it is more an accessory rather than a necessity IMO.

    c0138.gif ..you have a good memory!

    Yes, I faced the same problem with cracked plastic slides (later RS carbs were upgraded with aluminium slides) and found it impossible to locate replacements at the time..

    Nowadays the availability of the uprated aluminium slides has improved a lot though, so today I'd probably just buy these.. (quite pricey though..) http://www.allensperformance.co.uk/shop/ have these for sale in their webshop (just 1 left?) -> throttle valve RS36 

     

     

    My brain was screaming 'but they are aluminium' when I saw this - I thought you confused them with CV plastic slides! LOL The way they rattle around, its not surprising they crack!

    Plenty of people use electric pumps but they can't be described as geared and huge so I naturally assumed it was a mechanical one! I believe the mechanical parts like in mine come from 50cc / monkey bike engine oil pumps just built into a nice housing.

    This is mine - quite small but sufficient! That is an M10 x 50 screw that got modified to pick up on the pump drive and mate with the M8 cap screw holding the ign. rotor

  6. Well it is very green - it was originally a Lawson rep in green but I like it. And i'm with Clive - don't like short arse's on old skool bikes - too German for my taste. Still if the old lady ain't going too anything's possible. Not too loud I hope LOL! Enjoy. I've got a photo somewhere I'll dig it out for comparison.

    Don't know what they cost but I,m sure with a bit of work the pump bit could be mounted on a cover and be engine driven...

     

    Would work but total over kill as its rating is sufficient to turn the entire sump contents over nearly 4x a minute LOL!

  8. From what I can find the GSXR / GSX-F alternators seem to be 22-25A output so stacking all the electrical draws together (ie worse case with everything on) gives std bikes a little surplus for battery charging. Add in additional electrical pumps (fuel and oil scavenge) @ 6A each, wideband lambda's EFI (if fitted) and the system soon runs into deficit with no real alternatives unfortunately. The 'windscreen washer' type pumps used for oil scavenge with 1A draw are obviously more economical electrically.

  9. Well that's one thing off the list. If its all low end / idle range then its possible those circuits are dirty / blocked - carb strip time! What is the idle rpm set at? Does it idle ok?

  10. Plenty of people use electric pumps but they can't be described as geared and huge so I naturally assumed it was a mechanical one! I believe the mechanical parts like in mine come from 50cc / monkey bike engine oil pumps just built into a nice housing.

  11. Basic questions what are carbs from? 750 or Bindit? May be both 36mm but quite different jetting! The pipe and can will have an effect - initially i'd guess lean on decell / stopping - does it pop or bang? Does using the choke make it better or worse? Hopefully it'll have the bandit ignition and not the 750's!

  12. Any mechanical pump can be driven from any rotating shaft - I used the end of the crank. Bigger isn't necessarily better - they deal with small amounts of oil efficiently so are running 'dry' most of the time - my pump gears are maybe 6-10mm wide and 25mm diameter, enough for me.

    they all have a take-off, unused ones are plugged.

    The same take-offs are used for synchronising the carbs.

    Ha Ha Ha - shows how long since i've used CV carbs LOL!
