Thanks to Dennis which helped me figure out which thread repair kit and insert to use on my motorcycle. I know some use 14mm so I was unsure. Anyway the kit works great! From Wise: Thanks for the feedback. Yes some motorcycle's use 14mm. Best to check the spark plug size before ordering. If it's not easy to find the size by the spark plug number, a digital caliper can be used to measure the OD (Outside Diameter) on the threaded part of the spark plug. Usually with metric sizes the measurement will be just under. In example a 12mm will measure less than 12.
Tooling worked great. Took my time and was done in a hour. Took the extra time to use vacuum and a small hose to suck filings out of cylinder. Then for extra insurance I then blew through the same small hose right into cylinder that is when I saw the most filings coming out. I just used wd 40 instead of grease because of the chance of the grease and filings sticking to cylinder and not sucking or blowing it out.
Very easy to use
