Not sure if after market applies but people were running Lectrons in flat track before 1980 for sure, I was running little bikes but knew people that ran those on 250's and 360's
That's a chia pet bike if I ever saw one... And LA location with WA license plate? Something's a little fishy...
If you need to freshen up your pistons, please feel free to reach out to me. I can offer you a few options.
I got 31mm keihn on my 1981 seca 550 that i run v-4. come to the east and bring me out more. not noone in v-4 anymore, so i run v-5 most but way under powered in that class.
I'm in florida now but will meet ya at roebling v-4 if you want in 2021. Soon as i moved to florida they cut out jennings gp. Just my luck.
