    Have been meaning to post sooner but life gets in the way of bike shenanigans.


    After changing my spark plugs a few months back on my 93' I noticed some oil on the sleeve of plug #3.

    I put freshies in all around and riding for 2k km now I have oil on the sleeves of #1 and #3 and a nice caroma around the top of #3.

    So time for a fresh rocker cover gasket, and they are only 10 bucks from Japan so both front and back. I will do the clearance at the same time, PO claimed it was done 5k before he passed the bike onto me but PO's ALWAYS say that.



    Also plan to fix the carbs in the process, running much too rich; getting fuel smoke on hard accel. on hot days 40c+ the bike is a fairly unhappy chappy in slow city traffic and apparently my friend with a vfr800 claimed I blew a foot long flame out of the exhaust on a hard decel once. :target: Regular carb syncs have made a difference but I will adjust the pilots and hope that cures it, if that does not fix it more investigating. Ordered new carb boots because it is always a good buy on older bikes. My mileage has been awful 160 to 10 L riding around conservatively to 110 to 10 L after a burn through the countryside.


    And after reading advice on this forum, ordered a new thermostat. Can't find a write up for the 3rd gen specifically. I'll post up each in different sections to make navigating easier. THERE WILL BE PICS! Maybe even Australian beer reviews :drinker:

    Yeah I agree the front head is much too rich, excessive carbon build-up. And the rear with the oil leak are much too lean.

    It's bizarre because the previous owner said it was perfectly tuned for him, he never states he never had any fuel smoke issues or abnormal richness in the front. I guess it's likely it sat in his shed for a long time with stale fuel? Started fine the second I got it.

    It has an original two brother can and full system, maybe they just cocked up the jetting and he never really rode the bike much? Or it just sat for ages and it needs a good ol' clean

    All will be well when I get all the boots and gaskets.

    good deal on the new intake boots along with the carburetor over-haul. While your "in" there, its best to replace the t-stat, I know the honda book states that they want the t-stat placed in a certain way regarding the hole, (I think the hole faces forward.)

    I like the first four or so threads of the spark plug to have some colour too, its a heat range thing. Cadburry Eggs are for the Canadians are'nt they :loco:

    As suggested above, the plugs may not be showing their true colour if you let run at idle too long or had the choke on very recently.

    No plug chop done sorry I'll be clearer, I simply put 2- 3000km's of city riding on the plugs then rechecked. (I was testing to see if the rocker cover was incorrectly torqued or if the gasket leaked, its the gasket)

    Only use the choke 1/4 to start it running afterwards it is always off. I'll keep in mind that it may not represent its true colour though. I can run a plug chop on the weekend. Cheers boys

    Most parts should be here by next week can't wait to get my fingers all up in her business and make her happy

    I use some siclicone gasket maker on the half-moons, yamahabond works too, hondabond, grey-goo bascially.

    Don't smell your fingers after, "you have your fingers all up in her." On second thought, do smell your finger :pound:

    Okay, so all the parts are here but have run into a different problem now. More pressing as I use her for my work commute.

    Let my brother borrow her as he is stripping the carbies, he complained of it dying at the lights on him I was surprised as I have put over 10k on it and it runs like clockwork. Thought the regulator had gone as the bike stopped charging the battery. Did all the standard tests (stator, wiring harness regulator etc) seemed good and it is the original so went ahead and replaced it with a fz1000 reg. Wired it up, it seemed sweet charged above 13v, didn't die on idle.

    Thought well and good this is sweet. Rode it around for about 20 minutes and it died on me no charge. Pushed her home about half a km, she is heavy haha.

    New reg is fried, I could barely touch any part of the sub frame or battery it all felt extremely hot.

    Next step is the wiring and most likely trying to find a bad earth. I'll strip it all out and take pics of that process as well! This thread is basically going to be a how to guide on complete molestation of your beloved bike.

    Check AC voltage coming out of stator, If you still have the plug, cut it off and solder the wires with butt-connectors, and follow up with shrink tubing. You should have a FSM for this bike too. Keep a close eye on your brother when your letting your ride out, btw; don't think of it as a "molestation" its just quality time with your woman :loco: :vtr2: Cheers Good luck...

    Well that was a waste of a perfectly good R1 regulator :grief: That's what you get for making assumptions and not checking everything carefully! Bubye starter relay. AC voltage on stator is fine so no worries there rider :) I see a couple of replacements including the plug on ebay but not too keen on putting my arse on chinese wires, she plenty a cushion for the pushin' especially up hills haha.
