a new engine will show around 170psi service limit around 120psi. anything below 100psi isn't good. recheck the valve clearances

are they showing 90psi ? if so thats too low. did you have the throttle wide open when cranking ? and number 3 is higher than the rest so the valve must be ok. i wonder if all the rest are too tight ? i think you need to go back in and recheck them.

they are their for end float, if it was my engine i'd fit some just for piece of mind.

note sure what tap is on them but if its the one with 50mm hole spacing you'll struggle.

ive been messing around with my zuma, the backbone of the frame is quite wide so getting other tanks to fit is a problem unless you take a hammer to the underside !!!!!! i got the small ET tank to fit and also a gs1100L tank, i put together bits i had lying around the shed and ended up with this ??????

ive got them pic's on me computer, ive got a zuma project and been trying different bodywork on it. i really dont like the standard tank and back end on them

you need to do a bench test on the leaking carbs to find out exactly where they are leaking from. a common problem is the rubber tip on the float valve will wear and then fuel will leak out into the airbox or down into the cylinders.

have you fully stripped them ? they'll need a full strip down and check for ware and make sure all the drillings are clear, also the diaghrams are not split. make sure the needles arn't loose in the slides.

if all the butterflies are fully closed it can only be an air leak. what bike/carbs are we talking about ?

ok, are all the butterflies fully closed ?

when you balance carbs it can alter the rev's up or down, if it does alter the rev's you adjust the idle screw.

i had a chop with a gsx 1260 engine in it that had blown the head gasket, i couldn't find a new one at the time so i made one from copper sheet. i was dead chuffed with it i didn't want to put it on the engine

you said you fitted a second set of carbs and it was fine but when you put the first set back on it over reved, so the problem lies with the first set of carbs.

i tried an RF carrier in a 600 bandit wheel and it didn't fit but i didn't know what year both parts where off. i have fitted a 1980 gsx 750 et carrier to a 1200 bandit wheel as its slightly shorter so i can line up the chain with an off set front sprocket.

yeah their is, ive worked for a few dealers and some have the tool others dont. even Suzuki have a tool for installing valve guide seals, they use the tool for removing/fitting the valve guide, 09916-44310

its been a long time since i fitted any stem seals but the OEM ones ive fitted in the past have a metal insert, theirs no way you could push them on with your thumb as you risk damaging the top sealing lip where the spring sits, i had to use the factory tool to install them.

the bandit torque arm bolts to the swingarm so theirs no movement.

interference fit. you have to tap them on

their suppose to be a tight fit, if their loose their no good.

yeah true

thats some serious abuse no class out of interest, does anybody know the REAL HP of an early 16v 750 ?

well that 1100 EFE engine went for £870 are they worth more than the earlier one ? am i gona have to sell my sole to get one ?

im guessing your not going to use a fairing ? why not make some and make a feature out of em ? as they will be on show.

lol, so between us we might be able to make sense !!!!!
