Further update
still not happy with bike
set the exup valve correctly
then checked the air filter
it was full of crap, probably original!
Took it out
Ran bike and got it to rev into red on
half throttle but wont take full throttle
Removed carbs and noticed o ring next to
diaphragm on carbs 2 & 3 missing and a crack in 1 of the
tops.
I found some o rings at a local hardware store and will
put carbs back on after wknd
i think ive found my problem

Sounds like your getting there

is dremeling a h4 bulb to fit the way forward?

Wouldn't touch the lights but i've got a UK spec headlight for sale if your interested?



.............yes, i know, shameless post hyjack...........sorry

As far as I know the UK spec headlights with the twin paralever lamps are the same as the Jap ones and take the same bulbs, which is the problem.

You can use different style lamps but that's not really the point.

Thanks nick but I have a couple of lights
I just need 1 new carb top.
Typical I gave 2 partly dismantled sets away
Marti

Could you plastex it back together ??

I have epoxy puttied the outside, but thers a sharp edge inside
That could damage the diaphragm
Also where can i get a new air filter from?
And my needles are set on the richest position, is this correct?
Marti

You can get an air filter from Fowlers (or maybe a Yamaha dealers)

Thanks again evil, as soon as i figure out what the standard needle position is
i should be sorted.
Its on standard jetting but has a micron race can fitted.
I looked in th manual but its not shown

I have also cured my charging problem. I had a reg/rect off a 600r
i swapped it over and cleaned all connections and now im getting a constant
14.4v.

Im now after a decent rear shock and im sorted
