Motorcycle Repair: carburetors or electrical ?, gs 1150, suzuki gs

Question
hi ! I have a suzuki gs 1150 1984... the problem i have is when my bike has been running for a while ( the engine is hot ) sometimes i have a lack of power or poor running at low and sometimes at regulor speed ? when i turn the throttle and release the clutch it hesites before taking of...and sometime at low idle speed the bike wants to stall  but only when the motor has been running for a while ? I already change the spark plugs and the pick up coils (signal generator) and the problem is still there. I also synchronize my carbs..change the air filter..i checker the ignition coils they seem good the reading i got was 4.75 ohms

Answer
Hi Dominic,

Describe the appearance of the spark plugs to me (new and old plugs).

Was your MC stored for any period of time?

What levels did you set the synchronization?

Avoid replacing parts hoping to fix a problem. Verify a part is defective before buying expensive parts. If in doubt, do not order it.

Answer the above and we can resume from there. Include your email address as requested. I return pre-typed repair information files by email.
