I just took deleivery of my 70cc Yamoto and I am going nuts trying to find a replacement spark plug for this ATV..It comes with a A7RTC [NO brand name on it?]..I've been to 4-5 differant auto parts stores and no one can cross referance it because the factory spark plug has no brand name to it..

Has ANYBODY replaced this spark plug yet,and if so,what brand and what number?

Thank You.

 

I got a champion z9y I got from shucks auto store. They were able to cross it over for me. The only problem was they had to order it for me.

Hope it helps.

Thank You very much for that information,I will see if I can buy some today?

 

Roman,
a BIG 'thank you' for the z9y number..The very first auto store I went to yesterday was able to take the number you gave me and cross it over to a NKG #C7HSA..I put that new NKG in an she fired right up with no problem..The choke was a little confusing so I took the air cleaner boot off to see if the choke lever was UP or DOWN when in the full choke mode?I than used a permanent black marker to mark ^ as choke on...

I will use this quad exclusively in my ATV safety classes..I like the auto trans..It allows me to focus more on making sure my youth are doing the other important things like braking,throttle,weight shift,ect correctly and I wont have to be too concerned with shifting gears with the younger riders.

If this one works out,I may be buying another one real soon?
