Changed front sprocket on my CB750 K6 from 17t to 18t without open the chain! Almost new chain, super duper heavy type with 100 golden 530 links X-ring, riveted master link. Removed front sprocket only that had lost one bolt, rear wheel in front position. Sprocket bolts now fastened with blue thread lock.
I do not use bike between redlights nowadays. It screamed too much...
Yesterday changed pilots and mains in my Vm29 carbs again....
Hondaman ignition module got it place in the toolbox under the seat. Connected and ready to go with extra grounding wires from coils bracket to frame metal to metal contact.
Waiting for a not rainy day for test. Summer yesterday, today rain.
