I installed this TrailTech from DDM:
I checked the sparkplug on my Tanaka 47R engine. It was chocolate brown, which is good.
Then I rode eight miles to Ala Moana Park, just outside of Waikiki. My daughter and her friends were surfing there and picnicking. I relaxed for awhile, ate some spaghetti and fried chicken, then rode home again.
When I reached home, I wiped the bike down and adjusted both disc brakes.
The bike rides well, except the tranny is noisy. Maybe I'll pull it out and relube it soon.
