    GS750 rebuild needs help

    in Air Cooled

    Posted

    unless the airleak was massive it wouldn't stop it firing on no 3,  just weak mixture, the bigger the leak the weaker it becomes (relatively) make sure the float isn't stuck open on no 3 if it is stuck open it will cause that cylinder to flood.

    change all o rings, there should be 4, 1 on each of  the inlet rubbers replace and make sure they are well sealed to the cylinder head.

    have you checked for a spark on no 3?

    a good test for airleaks once you have put it back together and running is to spray wd40 or similar all over the inlet rubbers while running, if the revs raise/alter, then there,s a leak, no need to lag it, just a bit will do. if you are careful its possible to pinpoint the leak.

    sounds like no 3 is flooding though.

    17" wheel swap in standard efe forks/swingarm

    Hi, welcome to OSS

    bandit 12 5.5 straight spoke, will go in the swingarm  with maybe some minor grinding to the inner seams, offset front sprocket, 180 tyre maybe will maybe wont, dependent on the make 170 will go with clearance, i know cos that's whats in mine.

    front i am not too sure of, i normally swap out the entire front end for some later suzuki ones which is a piece of piss by the way,  a gsxf front wheel will go into the original forks.

    someone will be along who knows

    look in the builds section there's plenty in there for you to read.

    Bike looks tidy and in one of the best colour combos(y)

    start a build thread and post pics, everyone likes pics

    RTFR, and never refer to gsxf's as Kat's(y)(y)

    Like gixer1460  says don't worry about it too much, new small inline filter will flow plenty, get it running properly first, however having the carbs off and give them a good clean out is always good advice, ultrasonic them would be preferable, 3 years stood at least, prob going to be  shit / varnish in the carbs, this will cause problems.

    best advice i can give is don't skip  the carb cleaning step, it will save you hassle later on.

    There is a misunderstanding here, all the vacuum ports, one per cylinder, either on the inlet tract or carburettor body, or both, should be blocked off securely, except the one that is being used for the vacuum tap.

    if any/ all are left open or leaky then it will cause air to be drawn into the cylinders that is not metered by the carburettors, this means the bike will run very  weak, and will generally run roughly, it may not even run at all.

    I have known the vacuum part of the fuel tap to be faulty allowing neat fuel to be drawn into whichever cylinder it is attached to ( usually 2nd from left), the pipe which is used for the vacuum  tap should be fitted securely and be airtight.

    these should not be confused with the breather tubes which need to stay open as dealt with in the above posts

    Thanks mate,i would be much obliged, you must have a big shed full of bits(y)

    i don't suppose you would know of any threads where this has already been done, placement of brackets etc ?i did a search earlier but it didn't bring much up, to give me an idea of pitfalls/ things to watch out for/ bracket placement and the like

    fear not chaps, it will be staying monoshocked, i was just thinking outside the box, maybe a bit to far for the efe at least, i will sell the other two, i sort of had to have all three to get one if that makes sense.

    both the twin shock ones will i think fit gs/ earlier gsx very well, in fact one is for a inazuma 1200, which i think are the same sizes as a blandit, which i think goes straight in the earlier gsx's.

    Anyway now i have to source a gsxr 1100l/m/n, shock, linkages etc, i will place an ad in wanted.

    if you are referring to the link pipe or "c" in your pic you don't block them,they are supposed to be open, they do want some pipe on them though long enough to route out of the way, just make sure they don't get kinked or blocked.
