Re: Airhead LED headlight For 25 Bucks

Fully lit. $20 eyebrow, 60/55 headlight with Eastern Beaver loom, 35w HID. There are cheaper alternatives to the $20 6-7 LED eyebrow I use, eg ebay search "BA9s LED Bulb" The normal H4 in the headlight is bolstered by an inline loom with relay from Eastern Beaver. It takes some care to fit into the...

Re: For fork sake

I find the standard tool kit 36mm fork tool does the job perfectly well and never burrs the corners at all.
Just hold it in position and whack it with a mallet. Loose! Failing the oem tool...https://www.gbmotorcycleproducts.com/in ... ct_id=4746

Re: Bar vibration.

I have a K12r. My right hand can get a bit buzzy, never the left. I use pussy grips on my bike and they do help a little, but are not the answer. I expect some sort of cruise control that allows you to remove the throttle hand occasionally will help. To that end, I use hair ties at the grip to add ...

Re: Fuel consumption

When I started looking into how the Bing carburettors work, I was confused by the nomenclature on needle jet positioning; 1st, 2nd 3rd and 4th pos., but very little info on if you counted from top or bottom. IWHT leanest/lowest, 2nd lowest etc. would be more informative. Perhaps there is a consensu...

If your needle jets are old, new ones will pay for themselves very quickly.

Re: Trail braking (or my interpretation of it)

I'm presuming you're on the 1981 R100 /7T Jon K? I trail brake and have for years on both my 81 RS and 06 K12R. On the RS, just gently mind you, no stepping forcefully on the lever. I find it keeps the rear end settled and may reduce a little of the front dive. I rarely use the front in a corner. I...

Re: R100RS ENGINE NOISE

NOISE SEEMS TO BE COMING FROM FRONT OF ENGINE NOTHING EITHER SIDE OF 2500-3000 RPM GEARBOX SEEMS GOOD IN ALL RESPECTS.THANKS
The RS fairing can be very deceptive as sound seems to amplify from within it and from unusual places.

The clutch is prone to scream occasionally.

Re: Rebuilt Motor First Run

Personally, I'd ensure it was done sometime before or around the 1000kms. I wouldn't sweat on exactly when. If I was able to do a weekender of at least 500kms I'd be inclined to do it then. Three stage re-torque of the cold heads to 25ft.lbs, redo the valves, and for completeness I'd probably check...

Re: 1979 R100RS Sticking Front Forks

Maybe the forks have lost alignment? If you can lift the gaiters and lay a glass plate across the forks and you get movement and noise when moving the glass then they won't be parallel and will need sorting. This article is the full deal but you may not need to do it all. Do you use an aftermarket ...

Re: Has anybody used this company?

If a gearbox had swarf in it from one part wearing badly then would the seal on the bearings allow them to survive? I am imaging the seal as a sort of sieve, allowing thin runny oil into the bearing but keeping out larger debris. AndyB I've presumed the same. If that's the case and there's no reaso...

During the carb clean, was special attention made to ensure the small holes at 6 o'clock adjacent to the butterfly were clear? If not then transition performance can suffer. If unsure, remove the mixture screw and the pilot jet, spray carb cleaner into those tiny holes and ensure it comes out the b...

I've never done a transmission myself, so rely on others experience and knowledge. The maker of this video does a few every year and here is describing his experiment with sealed bearings.

There are experienced BMW mechanics that swear by sealed bearings in airhead transmissions. It's not unheard of.
