Yes, it was way more difficult than I thought it would be. The air filter replacement itself, when i finally got to it, was realtively simple. I'm glad I had something else to do while I was in there! I am not looking forward to wiggling the tank back on!


Pulling the tank when changing the air filters and replacing the clutch was way more difficult than it should have been.Guess that's what happens when you stuff 10 pounds in a 5 pound bag. haha

Both coils now installed. In order to connect the coil from the horizontal cylinder I had to remove the charcoal canister(which I had been meaning to do for ages). Without doing the canister removal there was no way I'd get my fumble fingers in there to connect the coil leads together!

Well, everything is back together including new air filter, spark plugs, Eldor coils and the full no judder clutch kit. I charged up the battery and the old girl started up once I found neutral. The good news is the bike started, the bad news is my odometer is still not functioning. Trip odos still work but still not the main one...hmphh!

It will probably be at least month before the roads are clear enough for a ride so I'll have to wait to see if I notice a difference from all the new bits. A little later this spring I'll take it to the dealer and they can adjust the valves, replace the cam belts, and tweak the electrics. Hopefully they can solve the odometer thing with the not yet done electrics patch.

Good to hear everything went great. Shame about the weather not cooperating though.
Finally got the HS out for a test ride. Bike started up and runs well and seems pretty darned perky. Cause I haven't ridden it for 6 months I can't really tell if the coils are making a difference but I'm going to say they do cause I want them to! Biggest difference was in launching cause of the newly installed clutch pack and anti judder kit.

I still love the 821 engine and the way it pulls this little bike. Especially considering it's at about 65000km and overdue for it's second valve adjustment and tune! Hopefully will get it to the dealer in a couple of weeks but hard to imagine it'll run better than it is now.

Yup it works. Thank you for the time U put in to source the connector parts.
After reading thru this post I figured I better be safe than sorry...
But, don't you know I waited too long. Hey, I have 42K whats the rush?
Finally stopped raining....time for a ride....whoa...what's this? Dash is blinking like crazy, mayday +limp mode mayday .
Trailer to dealer (thanks Nick @ Rockwell) Looks like yer ECU is toast.
Hey, it's only $2000 for a new one!
Ebay to the rescue + Eldor and we're back in business.

so after reading this, I got scared and just ordered a set of Eldor packs from ebay. Just got my HS in March and plan on holding on to it for a while.

dumb question: the eldor coil each have a different P/Ns: (857084, 857501) for cyl 1 and 2.
can I easily tell which pack is for which cylinder or it doesn't matter?

thanks.
