  1. Whilst i've used Dyna 'S' on plenty of engines it ain't exactly cutting edge is it! Mechanical advance, no retard facility or rev limiter - might as well use Breaker points ! Agree with the Mag thing though but when they do work you get a bloody big fat spark that would ignite water!

  2. if it has to run sequential ignition, a cam sensor is needed so the ECU knows which of the four cilinders is at compression stroke.

    Exactly - the actual camshaft position isn't critical to spark or injection timing - just to indicate where in the cycle the engine is - its generally known as a sync sensor ie. it synchronises the ecu timing to, generally, cylinder #1. 

  3. sorry if I'm being dumb but what one is this, do you mean the cam end blank hex plugs?

    No - its the round one with the allen key center down below and in front of the timing cover as above! Its the main crank oil gallery so make sure your adapter don't leak!

  4. A M8 used a set of FCR41's on a 1216 gsxr/bandit and although set up perfectly / had good top end, he lost so much in the midrange he's now swopped back to RS36's and loves them for day 2 day riding and hooning around!

  5. Depends on what GT25 you select ! Personally I think a GT2560R would do it but not ideally suited - I'd prefer a GT2859R or 60R unless you want to run lots of boost (and therefore heat!) all the time?

    Std. plastic topped CV36's will hold boost for a while but will eventually let go - swopping 'down' to tin topped 34mm CV's is usually bombproof.

    Again its down to what boost you are running but usually a smallish EFI pump and good regulator is required with a fuel return to the tank - must work at 2psi ie. off boost upto 15-16psi @ 1bar or more?

    Again, personally - an EFI system saves on engineering over a lot of these issues and releases more usable power through more accurate control of fuelling and timing!

  6. Lambda sensor placement is critical when using a dump pipe! When flow is low it will be fooled by atmospheric air so indicating lean condition.

    I've got my ecu sensor at the collector pre turbo - against all the advise mind you but if the back pressure kills it after a few '000's miles its not the end of the world

    to replace with a new one + its more accurate as direct from cylinders not with added turbo oil ! ! !

  7. MLS shouldnt have let go at that, what was the head torqued down to?

    You can't clamp as tight with stock 'springy studs and nuts - Go and raid the stores Clive, you know APE makes sense!

    And copper don't leak if its done right:)....... 2 bar + and no leaks here.

  8. Be ok Gixer, buells weigh 400kgs most of that's ditch pump motor lol, so gsxr is a feather weight by comparison! 

     

    I think you've got your KG's confused with your lb's - no way is a Buell 880lbs!

    And at 440lbs its a bit lighter than a std GSXR - not a lot but you've added 10-15 kgs of turbo stuff!

  9. Even better Robinsons list them.......http://www.robinsonsfoundry.co.uk/content/pages/shop/parts/Suzuki/GS/GS750/B-DB 1977/gs750boilpump.htm

    £61 and change - but they need to order so don't hold your breath! But OSS still gets discount - I believe 10%?

    But of course you also need the corresponding clutch drive gear.......http://www.robinsonsfoundry.co.uk/content/pages/shop/parts/Suzuki/GS/GS750/B-DB 1977/gs750bclutch.htm  Which will be another £73 and change and a wait. So about £120 all in new - I think i'd be scouring Eblag!
