Yesterday I started getting inside the old girl! Decided to balance the throttle bodies. Should be similar to balancing the carbs on all my old bikes.
Incredible journey.
Removed the bagster tank cover.
took the seat off,
lifted the tank,
warmed the engine,
removed the throttle cables at the throttle body,
removed the fast idler (choke thingy) at the throttle body,
removed the connector and then the sensor and reconnected them outside the airbox,
removed the screw that holds the other sensor on,
removed the crank case breather hose,
removed the Pair hose,
Loosened the throttle body clamp screws
removed the air cleaner box mounting bolt,
after lifting the airbox-
disconnected the vacuum hose, and
removed the air box
Having removed the air box I found that one of the mounting rubbers had been crumpled over and pushed inside the venturi rather than running around the outside of the venturi. It's pretty badly shaped and will need to be replaced. Probably like that for some time - heat and pressure have done their job to bugger it completely. Cost of the replacement intake $38.75 so it's not an expensive part.
This gave me a look at the top of the spark plug caps. Getting the plugs out will mean digging deeper. What a complex bike!
The balancing procedure was pretty simple, I have mercury gauges and the body for number 2 needed a little adjustment only.
What a bike

Hi Bill, what pictures would you like to see regarding this procedure?
Taking the airbox off is pretty comprehensively covered in the workshop manual. As is the balancing, mind you Suzuki don't use mercury guages.

 Good one Simmo
Hi SpamanGlenn,
I had some problems with my bike surging etc - which just got fixed. I was just reading the post and this one talked about removing the cables - (I almost did it - then I stoped - grabbed a naked blonde -don†t get any idea's - its only light beer) Then just pulled the air box -since all the screws and hoses were loose it came off.
I read here about balancing of the throttle body - thought this may resolve the issue - but didn†t need it any more.
Which brings me to another question - do we need to balance throttle body and if so at what intervals.
Cheers,
Bill

Simmo got it right in one - because we need to find out what makes it tick.
Actually I was putting heli bars on which neccesitated the removal of the cables, while at it I balanced the throttle bodies.
In answer Bill, only if your idle gets rough or you feel like having a tinker, not a hard job, and made easier with the use of the right equipment. You can get vacuum gauges though they aren't as accurate as mercury models.
Cheers

ok,i was just wondering why you,d pull off the throttle cables to balance the throttle bodies,thats all.I use the mercuries too but have learned to sit them low incase the motor gets thirsty.

From what I've heard about your motor it's a thirsty beast with more than a little grunt. How has your consumption suffered with the bore and other motor work bloke?

its all in the tune.I used the same as a gen2 and less than dad when we went to jindabyne.I just set it up around 14.5:1 up to around 10% throttle.using wide open throttle it can use around 15% more.

The map your sent over is using a fair bit of fuel, going to drop the map that Dynojet sent over and see how they compare. Rays is an excellent map no doubt.
One of the things that will hold me back from any more than the basic mods I have goes back to a Kwack thousand from 1979, went big bore, huge cams, smoothbore carbs etc and ended up taking three fuel stops between Canberra and Sydney on the old road.

Just highlightyour 2-10% throttle area from 2750-5000 and lower the numbers down by 5 with the page up or page down keys on the keyboard and save it as a revision.

I'll give it a go mate and see what happens.
Cheers and thanks for the advice.
