Time to put new spark plugs in your 600 Hornet? Buy a new bike - it's easier. The book says undo three bolts, pull the radiator forward, change the plugs and Bob's your ex-Prime Minister. Like hell! These instructions are from the same people whose countrymen enjoy TV game shows where people are bribed to put their faces in vats of live maggots and wade naked through ice. The three bolt thing actualy only gives you cramped, knuckle scraping, braile "access" to Plug Two. Access includes fiddling the lead off the plug and out of the hole, all the while hoping that all that wiggling is not stuffing up the electrical connection, then feeling the plug socket disappear below finger reach into the top of the donk while praying that that socket extension will fetch it out again and building a grabber into the plug socket that will lift the plug from the bottom of its pit. Getting to Plugs One and Four is really easy. Once you take the tank off and since you have already learned a lot from the horrors of Plug Two. The hard part was finding the socket extension. One second it was there, the next, p-o-o-f! Vanished! After a 30 minute search of the garage it was found snuggled up under the lip of the bottom of the fuel tank. It may have been hiding from the bad language. Contemplating how to get to Plug Three makes you wonder if the bike really needs all four cyclinders to run OK. The solution involves unbolting bits of the ignition system and contortionism. And the plugs I took out looked in pretty good condition. A zen experience for a Saturday afternoon.
