GS1000 8 valve with 3000 rpm problem

[PeterBoomhut]

OK, do the Colortune adjustment
Then, regarding the sync, are you trying to adjust the height up, or down?

what do you mean exactly?

What do you propose as a replacement?

Break Fluid should only ever be put in your brake master cylinder reservoir, it's highly destructive to paint. I have read of people spraying WD-40 around carb boots while the engine is running to detect air leaks, if that's what you're trying to do. Maybe even just water sprayed in a mist. Not sure about that, though. Maybe others can recommend something else besides WD-40.

what do you mean exactly?

When you are starting the sync, if one cylinder is reading higher, are you trying to adjust the other 3 up to match?
Or, the reverse?

[PeterBoomhut]

Please don't spray brake fluid anywhere. Maybe something got lost in translation here. Not a good idea. It will destroy paint.

I'm sorry, its break cleaner

I try the one thats is out off sync.

Peter, did you get this sorted?

[PeterBoomhut]

Peter, did you get this sorted?

No, the problem is still there. Synchronizing the carburettors had no effect, also another set of carbs put on, and another set of inlet rubbers with new O-rings had no result! Brake cleaner test had no effect.

Are you confident on your timing? It says you replaced the chain. Could you be off maybe? Just a thought.

Something strange going on here, i (think i) know Peter he's detail minded and exact.
(Boomhut ???) Something must have slipped by him.

Soo ... huge risk of dismissing the cause but if valves, cam timing, carb boots and carb cleaning and sync are ok ....

Peter, 2500-3000rpm is the point that the mechanical advancer should be at the max.
Can it be it's stuck ?

Is this the blue GS1000 with GS1100 pistons/cylinders and nicle frame and "The Clang" modification ?

We need pictures

Say HI to Jordy.

My thoughts exactly

If you go thru every possibilty on a carb problem, the solution is an ignition problem

Two men looked at it, it makes a lot of noise, but I think the clutch is outdated.

Yes, its me, my nickname

Valves; Checked by Yordie , seats are polished, Checked with gasoil , 1 & 4 exhaust leaked a minimum
Cam Timing, Checked By me and Yordie , half a tooth off the lead, thats odd because of the new chain.
Carb Cleaned, (both sets) checked channels with breakcleaner. New Orings ( http://www.cycleorings.com/VMkit.html)
Carb Boots, new O-rings and used new seat from Cruzin Image
Carbs are Synchronized.
0.5 oversized pistons and rings an Cilinders

We use a electronic one 32900-49410, with electronic advancer.

No this is another one, I Bought it in March 2019, that one with gs1100 pistons is crashed with his new owner.
(used the front brake when cornering)

We need pictures

Say HI to Jordy.

We did a leak test max 5%

Pictures, okay. Greetings from Yordie.

Carbs cleaned

Carbs are cleaned Ultrasonic

Hi Peter, it's been a while !

Those igniters are sturdy but can fail, causing strange issues.

Have you checked the connectors are clean and it gets good 12v and ground ?
