About igniter unit?

[Tompasio]

As i posted before my bike will no go at WOT,its hesitates over 120 km/h,
I have the carbs totally dismantled,cleaned changed every o-ring in carbs and boots.Changed mains from 120 up to 140.Coils have 12.6 volt when ignition is on,I wonder if the problem can be in the igniter unit? Bike starts very easy and runs well to about 120 when it starts to hesitate and slowly raises in speed.

Maybe. You could have a fuel restriction also. Too sharp a bend in the fuel line, wrong type of fuel filter, dirty filter on petcock in tank, etc... Just something to check. I had this experience, where it can flow enough gas at moderate speed, but can't flow enough for wide open.

I recommend doing plug chops at the region of the problem. Most likely the problem is related to the carbs, not the ignition.

I've seen bad igniters do exactly what yours is doing. Got a spare to check it?
The 120 main is probably alot closer than the 140.

I saw on the net a company in New Zealand selling something called HYPERPAK, a igniter box so you just change the old one.Had someone any knowledge of this box?

My igniter passed the tests listed in the shop manual, but I still believed them to be the issue. When I purchased an igniter from Hyperpak, that brought my GS1150 back to life.
