    Riding home the other day I started having trouble finding neutral and it felt like the shift lever rubber was rolling on my shoe. Sure enough, it had split most of the way across.

    Not having a spare I started digging through the garage for something suitable to get me by and viola, I now have a use for the 1" heat shrink tubing that came in the 5 pack form Harbor Freight.

    Cut to length and slips right over the rubber, shrink with a lighter and good as new. I think I'll carry a extra precut length under the seat in case a roadside repair is needed in the future.

    That's a good tip. I find a new lever rubber is likely to crack in short time, and your trick might help preserve them.

    That is a good tip. Also, if you aren't conveniently located to a HF or NT where you can get cheap heat shrink, my ST had appropriately sized heater hose or other water hose type on the toe piece when I bought it.

    It actually seemed to hold up better than the BMW rubber I've replaced it with.

    Anyone have a opinion on replacement front brake shoes for my r75/5?

    The general opinion I've heard is that EBC and Ferrodo are fine, and may even use the same braking compound re-branded. OEM brakes are better, but more expensive and quality control is sometimes an issue. The best option, but very pricey, is having the brakes professionally re-lined. Vintage Brake offers this service.

    I replaced the cross over pipe on my R75/5 with a $10 plumbing extension pipe found in the under-sink aisle.
    They are 12 inches long, brass inside, chrome outside, 1 1/4 inches in diameter..
    I ground the threaded section off of both ends of the extension, never-seized the header and slid them on.
    Slide it on further than the original, right up to the welds.
    No clamps needed.

    Much quieter and prettier than the 7 hose clamps and rusty tin the PO had wrapped around the old crossover.

    Just loaded this tech tip on our web page. Thought you guys might be interested. The speedo cable boot is often neglected and is a common source of water contamination in to the gearbox. Easy enough to do for the experts but can be a pain for the less experienced. A quick & simple method. http://rter.co.nz/Airheads/airhead_tech/speedocableboot.pdf

    Hi folks. Hope you're all enjoying the season. We've just listed a new technical bulletin at our website on the topic of a repair method for spun rear wheel hubs (i.e. early models with bearing stack assembly). If you're interested feel free to check it out. http://rter.co.nz/Airheads/airhead_tech/spun_hub.pdf

    Having ridden airheads for the most part since the mid '80's my observation regarding the double reserve trick.
    NOT A GOOD IDEA! when you are running at anything more than 3/4 throttle for any extended period of time. The two fuel taps are just big enough to allow for sufficient flow of fuel at high revs. My 1983 R100 had a 336 degree cam fitted with a decent pair of pipes. Used to go really well and 210-220 km/h on the clock was nothing unusual for it. Coming back from Cape St. Francis with a stiff South Easter pushing from behind I just had to see how fast she would go, the needle on the airhead does go past the 220 mark so I guess I was well onto 235 - 240 indicated when she decided to run the two floatbowls dry. Beeing a mechanically sensitive kind of fellow I decided to cruise a bit slower at the 200 km/h mark and all was good. This was with both fuel taps on.
    Long Story Short: The double reserve trick is fine when you are ambling along and cruising at moderate speeds, when caning the beast switch to both taps and your airhead will thank you for it. After all it was designed that way. Other point of concern is that with one fuel tap on the "on side" cylinder will get most of the fuel flow with the opposing cylinder may be running lean at times.

    I see no point in a double reserve "trick". You have the same amount of fuel, you can only go the same amount of miles. I don't know about you but I am going to stop at the first station I see. I don't need to be told twice I'm almost out of fuel. :deal

    The first time I tried it was also the last time. I had turned only the left side on and got 25 miles further just on that side so when it ran out and I switched the right side over I figured I was good for at least another 15-20. Not quite, I got to call my wife 5 miles later from the side of the freeway. Luckily I wasn't all that far from home and it was a Saturday, bad part was I had to get my wife out of bed..........
