Post need replacement spark plug for chetak 2-stroke (1991) Reply with quote
My Bajaj Chetak 2-stroke (1991) had a stock spark plug of Champion L92YC. Since this Champion plug is no more available in my area, i have replaced it with NGK BP6HS. Is it a correct replacement keeping the Heat Range Factor in mind? Or should I use more hotter NGK plugs like BP5HS or BP4HS?

6 is pretty hot to run in it, unless your doing slower speeds in the city. I have a B7HS in my 77 Chetak 2 stroke. How does the plug look, what color?

B7HS is quite colder.... My spark plug remains blacky, showing a very rich mix. Engine stops due to carbon deposition if i operate the scooter at slow speed with frequent clutching
