    Installed them today, first thing is that there's virtually no difference in sound while running, the H pipe is about as quiet as the collector box. Second is I notice no difference in power, feels identical but haven't been at top highway speeds yet.

    Of course the bike lost what feels like 20lbs, and my collector box was pretty rusty/minor holes etc - I was able to finally see the backside and bottom of my transmission, and clean the area. Much sleeker look.

    One thing I noticed is that all the stock BMW gaskets I bought really didn't fit from the years of cooked on old gaskets. I had to cut the 2 rears down to slip them in the cans. The fronts (soft gaskets) didn't fit at all, so I used a bit of red gasket sealant. So far no backfires.

    I'm sold on Moto-bins, they're quick.

    If you replied to the order confirmation, I think that's an automated response and maybe a reply to that is something that isn't seen? You can reply direct to Damien from a link on the front page, just remember to include the order number. They get back to inquiries very quickly ime.

    <center>Neimann keys decoded

    </center> So, I had this key and needed a new seatlock: no key code, just the key. Searched the internet and it came up with the information: There are 5 cuts in equal distance from the key stop, the deepest is a 1, no cut is a 5. See a couple of examples hereafter.

    Addendum thanks to Kenny from Huntsville, AL (email Kenny directly)

    ... I took my cylinders out and measured the actual spacing between "tumblers" at 2.68 mm and the distance to the first cut is 3 mm.


    <center> [​IMG] </center>
    The "tumblers" are only 0.67mm thick and the slots that they ride in are 0.90 mm so there is quite a bit of flexibility and slop if you use a round file. Now i was able to fine tune the key by fitting it to the cylinder and making adjustments--it's perfect. I used SR61N blanks but had to file off the hump of the big key stop to make them work.

    Also you may be interested to know that if you measure the distance from the rail slot on the reverse side (seen in your pictures key 4 and 5) to the bottom of the "cut", the distance is an even value: Codes 1,3, and 5 are 1.0, 2.0 and 3.0 mm, and Codes 2 and 4 are 1.5 and 2.5 mm from the rail edge to the correct "cut depth" for that particular Code number. ... The measurement is easy using an outside-measuring caliper.

    Why does it mater what color the tank is?

    I've never heard of a generic gas cap that fits that gas tank. Then again there are many wonderful and strange things in this world that I'm not familiar with, so don't give up hope just yet.

    Actually, the /5 can be upgraded two levels. I can do the mod for anyone that wants.
    There are three ways to do it, I like the simplest way.

    I seem to recall someone mentioning that older gas caps from Lincolns (60/70/80's) work but just here-say on my end.

    No changes in carb settings, runs great - but not much heavy riding to test these days, busy planning a sneak attack on the front end soon....

    Just a little unrelated trick:

    Sometimes the oil filter is hard to get out. Most of the time, for me anyway, a magnet gets it.. but on the barn-finds, the filter is usually stuck a littler harder. Then it dawned on me, a paint can opener:

    Worked perfectly.

    Now that you say that, paint can openers look to be bottle openers too.

    I just looked at the three I have in the garage and the handles are all identical and look like bottle openers. I'll have to buy a bottle or two of good beer to test them on. :D

    My Dad always said the same thing.

    His conclusion was that sniffing solvents all day was kinda like drinking all day.

    Then when they get off work, they kinda keep that going for the rest of the evening.

    Don't know if this has been mentioned before but I found out today that the small tire irons that come in the Airhead toolkit are perfect for removing the spacer the rear engine mounting bolt goes through. As many Airhead owners know, removing that spacer is the quick and easy way to get to that damn neutral switch that is so prone to leaking.

    I just pruchased an '86 R80GS and the headlight is anemic, scary even.

    Rick Jones, from Motorrad Elektrik, who sells the excellent alternators, points in a can and superb starters for airheads, and more, told me that he ordered an H4 HID bulb kit for his R80GS and it DOES fit inside the headlight assembly. I had previously tried to fit an H4 HID inside the headlight bucket of my R90S and there is no room for it.

    Rick said such a bulb will fit the R80GS. He ordered one from his local dealer who got it from Tucker Rocky, but they are available all over the internet.

    Key is finding one that has a small ballast and is good quality. I am elated to find out this information.:rofl

    Rick's stuff is here:
