Yeah I meant flamed for putting it in a confined space without ventilation. I have had this deltran for 2 years now and even left the ignition on overnight once (oops) and it's still been good.

Ah. Thanks for clarifying. 

Here's another opportunity for posting my gratuitously long signature!

but its a good quote.

I'll allow it.

Ok, Cal. I made some edits to take up less space (like your wiring).

Hang on while I scroll down to read the post I was more expressing astonishment at your build list, by the way.

More like a ADD distraction list.  Same list for the last year or more.

Woo. Installed it last night.

For those interested in the HondaMan Ignition and are running an electronic tach, tap your tach lead to the ORANGE wire.

I stuck it behind the battery box to the plastic fender with some industrial velcro. I unhooked my condensers but left them attached under the points plate just in case I ever need to revert. I also need to adjust the timing now. My previous issues with 2/3 being off might have been due to the condensers. I was only able to time correctly by closing the gap to 0.011". Anywho. It runs and revs just fine, but I need to recheck things, and that will happen on Monday!

I has my first ride with the new ignition module today.

WOW

what a difference. Power all through the revs is an understatement! Pulled right up to 130km/h in 3rd gear and could have kept going! But I was over the speed limit... Just a little bit... Before, I would hit a wall when the revs got above 7-8K.

Easiest cold kickstart in my life today too.

Thanks again, HondaMan. I will be praising this little box of magic any chance I get!

Rhonda was a one-kick pony up until a few weeks ago... Now only kicks when she feels like it.


After:

1: Replacing my carb boots because they were cracked
2: PERFECT vac sync (no rattle at idle now!)
3. Setting static timing just right

It feels like this bike will never start with kick. light pushes to get it to compression, up and down hard... NOTHING. I used to be able to kick start no problem, even when it was +2C outside. Feels like there is no resistance when I kick, almost. It just seems so strange. Sometimes it'll go first kick, but most of the time I get out of breath and resort to the push start, and she fires right up.

Then I got my HM Ignition...

4: Installing HondaMan ignition module
5: Setting my dynamic timing spot on with timing light

I thought this would fix the problem, but still no kicking!

Nothing else was changed.

Ideas welcome...

Check your points to ensure they aren't too tight or shorting to the plate.

[evanphi]

Turns out that my previous major vac leak was making things really rich and easy to start.

Closed off my air screws to 1/2 turn, so kicks just fine now.

[RAFster122s]

You fixed the vac leak and it became rich?  Glad it is kicking over well now and all is well...so get out there and ride and share some more videos...

Fixed vac leak and it became more lean!

Got my new stainless Delkevic headers in the mail today. Collector OD is 2.5", ID is 2.25". My current muffler is 2.25" OD. Womp.

So what I have is a slip-IN rather than a slip-ON.

Would this still be ok if I clamp it? Is there a exhaust-capable liquid gasket maker to avoid leaks (yes, Permatex Ultra Copper)?

Should it be welded? Or should I have a reducer made up so that it is still a slip-ON, technically (least fav option)?

[calj737]

Or, you can cut small notches in the header end, and crush that to fit inside your muffler. I'm no fan of a slip in, the exhaust gas will leak due to pressure. Weld a reducer or slice it would be my recommendation.

[evanphi]

FUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUCK

So much for my exciting two day moto trip. Was doing a valve adjustment because I noticed #1 IN was being increasingly noisy lately... It was the only one out of spec. Here's why:



Good thing I did the adjustment or I would have ended up stranded sooner or later!


So HOPEFULLY I can get one tomorrow morning from the dealership. Are there any other manufacturers (kawi, yami, etc) that have the same size adjuster that I could check their dealerships, too?

[calj737]

Immmm, I don't think its supposed to be like that from the factory

That about blows! I am happy for you that you caught that before riding off and chewing up your head

So am I... I noticed on my ride Sunday that it was noisier than usual. Hence why I checked it tonight before heading out on a 1100KM round trip...

This is testimony to experience. Notwithstanding your misfortune, but, your experienced ear knew enough to investigate properly before tearing it up. Many might have ignored it, ridden on because the opportunity was in front of them, and then dealt with the consequences later. Hindsight may be 20-20, but experience is priceless. Not worth much I'm sure, but hats off to you for taking care of your girl!!!

I was set to embark on a 1,500 mile trip Saturday with my wife's SUV. I got about 20 miles form home, turned around and stormed into the house. AC Belt tensioner was shot, rear diff was howling like a hungry coyote, and the wife's only reply was, "Its sounded like that for weeks, whats the issue?" Lord knows how long it would have run before blowing up and leaving my roadside... 

She will make a full recovery and should be able to walk properly in another 8 weeks according to the doctor (he was required to remove my foot from her arse).

Well I ran into another UNexpected issue about 200KM into my trip on Wednesday. I noticed that my #1 plug cap was hopping at idle. I figured my plug was loose. Boy was I right! THREADS WERE STRIPPED. How this happened I don't know. I am always careful when installing plugs. Guess not... So it got fixed with an M12 tap to revive some threads, as well as some LocTite Bearing Mount. It held up fine for the rest of the trip! But this does mean the head is coming off this winter to do a helicoil.

The bike looks good Evan,how was the trip ?

to Halifax? It was great once I got that sparkplug back in. Going to be repairing those threads this winter. Avoiding removing the head.

Here's Rhonda's latest adventure, including some light offroading.

[evanphi]

Is it possible to service the lock/tumblers on our keyswitches? My key is getting difficult to insert. Once it is in there it is fine to turn.

Or should I just order a new switch set?

Kudos for using a Tragically Hip tune to kick off your video.  Love that band.

If you have a locksmith do it you will have more hair after the experience.  It can be quite intimidating with all those tiny pieces.
Normally a locksmith is able to handle many needed repairs.  It is not too costly, provided it is a quality lock that is original Honda, instead of a cheap Emgo pos.
