How do you balance the throttle bodies on a K8? - SV650.org

Haynes manual says you need a special Suzuki tool, is there another way?

yeah you can make a home balancer, plenty of examples on the net, but I wouldn't trust there accuracy, see if someone local has a set you can borrow for a beer or two.

Hmmm...manual says it needs to be done with the SDS (Suzuki Diagnostic Scanner) so that you can set the idle speed control (ISC) value between the two cylinders.

After some searching, you can get a tester that looks like it will do this for £140 here.

Is this techno tomfoolery or necessary kit?

Normally the dealer would do this as part of the servicing whenever they check the valves etc, however if you're doing servicing yourself, might be worth having?

Thoughts?

yes you do really need the gizmo box as you have to lock the throttle bodies and lock the rpm.

i tried to do it to my k8 without it and it made no bit of difference to the vacuum gauges. i also found out that you dont adjust the balance screw but adjust the 2 little air screws instead.

i think the box your looking at is a re branded chineese one that you can get direct for £90.

Hmmm...58 squid delivered....that's not bad considering local dealer wants £60 to balance them

I just ordered one, they'll post Monday and said it would take 15 days. I'll report on here once it arrives.

Oooh...my goodies have arrived...not bad considering I only ordered them less than 2 weeks ago!
