Decided to try the 91 octane like everyone else seem to use in there Grom and now I can't get pass 54 mph on the same roads that I ride on, all stock Grom except I changed the spark plug back at 10 miles on the ODM to NGK CPR7EA-9. I now have have 1100 plus miles on the ODM and it was running great with the 87 octane hitting 60-67-69mph with no problem and now with the 91 octane it went to the dogs.
Maybe that is why a lot of Grom riders are saying they can never get pass 55mph etc. Anyway I can't wait till this tank of 91 octane is used up and I will go back to 87 octane. I will first remove the spark plug and look at the color on the core and then switch back to 87 octane and ride for two tank fills and I will recheck the color of the spark plug core.
Since this is Sunday and most places are closed the expressways and roads where not congested so high speed testing was a breeze.
I did stop at Home Depot Santa Clara to pick up a steel rod that had the right/close diameter as the Grom axle and it was snug enough for the wheel bearings to slide through since I was making a balance rod for my Grom rim/tire. Met a gentleman in the parking lot who asked a few question about the grom and he rides a ruckus.
I also met another gentleman at 7/11 store who question me about the Grom since I had to stop and recheck my steel rod to make sure is was secure on the Grom.This guy also rides a ruckus.
Anyway home now re-cutting the steel rod to length so I can balance my gold rim/tire.
Hey ride safe all
