OK...the tires are tubeless. I managed to air two of them up but the tires are old and stiff. Probably will get 4 new tires.
One minibike started up, but had to run really rich with the choke on to get it to go. Sounds like I need to clean the carb and get a new plug to replaced the 13 or 14 year old one.
The clutch was still sluggish when I rode up a hill, in the dark. I forgot to say, "Watch this!" before I did it
I found the old brakes that were removed...I think they are complete.
Ultimately these minibikes will be going to our hilly farm. I would love to be able to ride the trails. Any advice on getting the clutch to grab on hills better will be greatly appreciated. Did my kids overgrease them?
