I've always left them on the motor. You just have to have the clamps in the right position. Swap the screws for Allens too. The heads are always chewed up by monkeys using cheap screw drivers at this age.

Do as tsb says but make sure the clamps are undone enough for the carbs to slip into. Apply a little wd40 around the edge of the rubber and also around the carb part. They should slip in very easy. They are very awkward getting to the screws. Like tsb said get some Allen bolts and a set of long Allen keys makes life a lot easier. :nod:
Bit of advice. Buy a good bed and a good pair of shoes, because if you aren't in one you'll be in the other.

Also flip the clamps so all the heads face the centre/head stock. Makes access to them simple
I swapped them al for stainless Allen bolts and then bought a 1/4" air ratchet with hex bit. The clamps now take a couple of minutes. The hard part is getting the carbs into the rubbers lol

Lookout for one of these on your travels. Well worth it's weight in gold for doing those carb clamps up with. :nod:

well with a squirt of silicone spray i got the carbs on.
i had one of the bendy screwdrivers in my tool box (never been used).waiting on replacement cap heads but happy they are on .
now i see 2 of the bowls need to be swapped to access the overflow screws .
and the choke cable is a delight to get on.
thanks again
mark
new question so new thread.

well i swapped the front and rear wheels,forks and swinger etc.
and tried to start it again .
no joy. :crybaby:
i had it running and idling nice before the surgery.
but had to use "carb starter fluid" to get it to fire up .
it has fresh jets,diaphragms,and plugs and pump.

i suspect the choke circuit is not functioning properly .
no fireing at all
it has low comp on 1 cylinder but it should still fire .

all the bowls are getting fuel.

any pointers would be appreciated.

thanks mark

I usually fit the choke cable into the cable holder before installing the carbs back on. A lot less fiddly than doing it afterwards. Having read your thread underneath, maybe you haven't got the cable fitted into its holder correctly.

Thanks for the replies.
if the kill switch or side stand switch are activated it will not spin over.
i will look at the choke cable to be sure its getting enough "tug"
thanks mark

NOT STARTING

Post by two-stroke-brit »

Well life got in the way and i have only just got back to trying to move on with my 89 starting issue.(cranks but not fireing)
i read in a different post see below.
"On my '89, the fuel level sender, when tripped, causes the ECU to cut ignition to two cylinders, thus simulating fuel-starvation. When moved to 'reserve', it restores the sparks, thus reminding you you've only got x miles left."
now my fuel switch is disconnected.
would that cause the same issue.
thanks mark
