Premium Member bugsplatered Posted September 27, 2020 Premium Member Share Posted September 27, 2020 I want to change my spark plugs but cannot remove the coil packs. Does anyone have any tips on the removal of coil packs? Link to comment Share on other sites More sharing options...
Buggy Nate Posted September 27, 2020 Share Posted September 27, 2020 Twist as you lift, a slight burst of air nozzle pressure in the spark plug drain hole under the exhaust ports can help too. 1 Link to comment Share on other sites More sharing options...
koth442 Posted September 27, 2020 Share Posted September 27, 2020 Pull up, pull straight, and most importantly, pull like hell. '15 FJ09 Link to comment Share on other sites More sharing options...
timo50 Posted September 29, 2020 Share Posted September 29, 2020 I found that the easiest way was to use a cable tie, make a loop, hook it under the coil and pull up. Link to comment Share on other sites More sharing options...
Premium Member bugsplatered Posted October 9, 2020 Author Premium Member Share Posted October 9, 2020 Thanks for the advice. I removed coil packs two and three by hand but had to use double-hinged pliers and shop towels as a fulcrum to leverage coil pack number one.

skipperT Posted October 10, 2020 Share Posted October 10, 2020 Typically theres also usually a small hole for water drainage located somewhere on the cyl head - on our bikes it’s around the exhaust headers. A blast of compressed air in that hole while simultaneously twisting the coil pack can also get it free (disconnect the wire first!) I swear Yamaha engine guys must pound the coil packs into the engine with a rubber mallet on the assembly line... -Skip 1 Link to comment Share on other sites More sharing options...
peteinpa Posted October 10, 2020 Share Posted October 10, 2020 Same set up as my previous FZ-07. I made a loop out of string and pulled while twisting. 1 Link to comment Share on other sites More sharing options...
Wintersdark Posted October 12, 2020 Share Posted October 12, 2020 When reinstalling them, lube the sides with dielectric grease so they come off nice and easy next time. Be sure to use dielectric grease, not some random grease. I had a bloody hell of a time doing this on my old MT07, as there wasn't room to pull them straight up but they were stuck so tight. Terrible, terrible job. I'm very thankful they're readily accessible on the Tracer, as I just received my new plugs and need to change mine this weekend. 1 Link to comment Share on other sites More sharing options...
