  1. Gates 'technical' tell me that all belts should have some tension when cold...........but what surprises me is how tight the belts get when the engine is hot, despite doing the 5mm / 6mm allen key method.
     
  2. cheers al i was suprised how tight the belts got when engine was warmed up
    was going to take it for a run today but weather is a bit wet and horrible here
    well at least my sanity is having a reprieve :biggrin:
     
  3. okay guys been and had a chat with the guys at italia moto today about a few bits on the bike
    asking about valve clearances bits and bobs
    mentioned about the miss fire and firing back up through the throttle bodies
    suggestion is possibility wear in the bottom end of the engine that throws out the timing for the sensor bad news if it is its an engine split
    asked of i had checked sump plug for particles ......answer yes it looked like a christmas tree when changed the oil
    had read on here where other people had similar......... suggestion was it was gearbox particles not loads to worry about
    turns out it might be something to worry about
    if it is what is suggested looks like it might be another engine........ well have half expected this from the beginning but not for this reason
    so lets see what happens lol
     
  4. Mine doesn't have a sensor but I had experienced problems not dis-similar to yours.......

    .....however, one thing that might be worth checking on yours are the pick-ups which can partially fail, but also, one could have loosened a bit.......which would give you the misfires etc.
     
  5. well hopefully i will get to the bottom of it eventually
    and it might serve as usefull info for the future lol
     
  6. well bit the bullet on friday o_O and bought another engine
    need to clean it up a bit and sort service parts
    and wait for some good weather ................oh that would be today ..........but not with a hang over ;)

  7. Complete engine is probably the most economical solution, are you dropping a 900 into it?
     
  8. no not dropping a 900 motor in keeping it as a 750 still at the moment
    will be happy just to get it running ;)
     
  9. so spent a couple of hours on sunday cleaning up the engine ready to be fitted into the bike
    already checked that bolts and things on the bike will come undone
    got the exhaust off and no broken studs whoo
    already got some new copper coated exhaust nuts
    air box removed and cleaned
    and so far only issue with new engine was oil cooler mounts
    the rubbers had broken away and left the threaded section in the rocker cover
    hah so out came the molegrips lol
    out came first one easy ........second one made of cheese snapped straight away
    of with the cover and in work today drilled and tapped sorted
    just hope the swingarm goes as easy lol :Wacky:

    whoa dude loads of new smilies

  10. so a busy day nipped up to moto italia to pick up new oil cooler mounts and an oil filter for new engine
    getting quite regular first name terms with terry now lol
    so back home and continued to strip the bike
    did pretty well dismantled and engine out ready for new engine in
    everything came undone fair easy including the swingarm spindle which was well lubricated ;)

  15. Progress indeed, hope your install goes as smoothly. You'll have it sorted in no tme
     
  16. okay guys engine in running gear back on
    no major issues but found an inlet rubber on new engine had a split in it
    oh joy spanner does not fit on cant get a socket on bah
    so out with the angle grinder to thin out the ring end of an old spanner whoo job done
    but then find one nut on the old engine for the inlet is rounded off rats
    hacksaw and chisel job done
    so just need some fuel hose clamps as old fixings look well crap
    just small jobs like airbox and exhaust to put on then oil and filter to do
    took a piccy hope to get it on later :D
     
  17. fu*$%g bike ........................

    going for a bath and alcohol back later !:Banghead:
     
  18. right slightly better thats me anyway probably the schnaps
    so anyway got to start the bike tonight battery on and away we go
    checked i hadnt left any thing off no so hit the start button
    (or the magical noise button that the fairys work behind)
    couple of coughs .......okay press button again whoo noise it runs
    then notice the oil pressure light hasnt gone out argh stop engine quick
    check round no leaks check level gone down a bit but not a lot so top up anyway
    try again starts up on the button light not out and engine sounds uneven
    so try a little revs to see if that brings pressure up to kill the light whoo it goes out
    well for about minute
    so after investigation oil pressure switch was dud good job i had a new one on the other engine
    so light stays out when it should
    right a bit braver on the revs uneven running clears with a bit of high tickover
    revs quite freely sounds a lot better engine than the old one
    then went back to running rough
    so swapped spark plugs .......................nope
    tryed my spare coil no difference at first then started running better with spare coil on back cylinder
    so swapped coil back still running fine revs lovely just had to up tickover
    then things got interesting sounded rough again when warmer not missfire just rough
    and when revved flames out of the exhaust but not on the overrun
    well thats a new one
    it did smell rather rich think it could be over fuelling ?
    so tryed revving a couple of times see if it cleared nah it did stall at one point
    and after it had stopped the right hand exhaust was on fire .................funky .not
    upshot the bike seems to be overfueling loads and chucking loads of unburnt fuel into the exhausts

    more alcahol :Mooning:
