Some prick backed into my bike and bumbed it over, that's what you get for parking directly behind a car in the roadhouse carpark I guess. I thought he was in the shop! Not sitting in the car eating breakfast. Doesn't matter, just a few scratches and a broken brake leaver that the insurance is going to pay for.
It goes in tomorrow for some new lower fairing bitz, RHS and I thought I would do that bloody oil filter today since it requires removal of said bitz. I did that and decided that since the tools were out I would replace the plugs. I bought the Denso (lol, what a name hey) iridium plugs a couple of months ago for $80 the set. I know some of you recon that they never need replacing but if you have ever been stuck in the middle of nowhere with a dud plug you tend to look at things differently.
I had the manual pages printed out and a great write up from Hayabusa.org to go by (though instead of using silicon spray on the rubber I used spit, with a little biscuit mixed in there too I think?) Anyway it was a pretty straight forward job I thought.
1/ Seat off and Tank up on its leg after removing the 2 bolts up front
2/ Pull off 3 hoses, disconnect 1 sensor and slide off another from airbox
3/ Undo the air box bolt and loosen the two 3mm throttlebody clamps
4/ Wriggle off the airbox, unclip the coil leads, pull the coil packs off
5/ Pull the plugs out.
I think the most important part of the web directions though was the pulling out of the plugs with a magnet if your plug spanner rubber is shonky, and most importantly
BLOW AND OR VACUUM AROUND THE COIL PACKS
I did both, there was tons of crap up there and I used a small vacuum cleaner and also blew out the plug wells before I pulled out the plugs.
It even started after I put it all back together which was a bonus. And I had no parts left over except the old plugs, which is a sure sign the job was probably done well. I did have a little help from a $400 3/8 drive tension wrench, just to get things right, but all the rest you could just about do with the tool kit under the seat. In fact I'm sure you could.
