Re: R80RT mono tube or tubeless pro's & con's

The few downsides to fitting a tube where it is not necessary are: the expense of buying 2 tubes( and maybe a spare), increase of unsprung weight ( albeit relatively small in comparison with the heavy wheels), making an easy, side of the road puncture repair quite a bit more difficult, ( wheel will ...

Re: R80RT mono tube or tubeless pro's & con's

Hi, Mark Maybe if you are not riding for an extended period, it might be an idea to support the weight of the bike and let the air out of the tyres. Although, if your bead is breaking under the weight of the bike, maybe there is a defect in the tyre? When you consider how much force is sometimes req...

Re: Rough Boxers

Of course it's completely a matter of taste, but I know that my head only turns when I see an old bike with a few battlescars and big miles being used as it was intended, especially these days when it is rare to see anything more than 10 years old on the road. Maybe it's just Switzerland. My own bik...

Re: Spline lube

Hi, Andy Mileage isn't the main factor, I think time is probably more important. My 1990 K100LT only had 95,000km when I pulled the gearbox to lube the splines. The splines were in pretty good condition, but the original grease was pretty dried out and I was glad to get some fresh stuff in there. I ...

Re: Faint Glow from Charge Light

Hi, Andy Your glowing kitchen spotlights is due to inductance and capacitance between the supply cables and not a 'leaking' switch. It is probably costing you no more than a few pennys' worth of power per year. I have l.e.d.s in my cellar which glow faintly all the time, I find it quite useful as I ...

Hi, John
You didn't say where the noise is coming from, engine, forks, gearbox, wheels, final drive...?
As for Britains eligibility to enter eurovision, anybody's guess considering it's being held in Palestine.

Re: Upgrade Voltage Regulator or Not?

Hi, Rob I swapped the original voltage regulator a few years ago for one of the adjustable ones, as I had installed a Motobatt battery and had assumed it would require a slightly higher charging voltage. It seems to be working fine and I get about 14.5 volts at the battery. I think it was about 20€ ...

Re: Krauser Heads

I bought a R90s cockpit off him a few years ago and all went to plan with the transaction,
we exchanged a few emails about colour and price and he was fair enough to deal with.
So I wouldn't suspect anything dodgy, but as always on ebay, be careful.

Hi, Gogs
I don't have the sidecar mounted yet as I want to get the bike running properly first and it's
easier to work with it without the car.

Re: Weird?

Thanks, Rob The switch seems ok, I couldn't make the fault occur on purpose i.e. I tried to make the cct live with the switch open, but my main suspect was my cigarette lighter socket which is connected directly across the battery (for charging purposes) which I had considered very well insulated fr...

Re: Weird?

Yes, Charlie, but can an alternator store voltage? Other components in the circuit are regulator and ignition, the rest is just wires, bulbs and a couple of LEDs and I repeat, the battery is totally isolated( maybe I should say "disconnected") from the bike, just sitting there on a rubber mat in the...

Re: Shipping to New Zealand

Hi, Global I was in NZ 10 years ago and found I could pick up a cheap used motorcycle and resell it almost for the same price 2 months later. I bought a Honda 1100 Shadow for 2200NZD and sold it before I left for 2100. It wouldn't have been my first choice, but I bought it in a hurry and I kind of b...

Re: Cylinder Exhaust Flanges

I have been tempted to leave them out also ( the 10 mm nuts) as the rocker covers on my Dnepr seem to seal ok with just a 14 mm centre nut (well , more or less!) but I came to enjoy the challenge of getting them back on, good for manual dexterity and good excuse to remove the exhaust nuts and grease...

Re: Cylinder Exhaust Flanges

I like to loosen and grease my exhaust nuts when I check/adjust my valve clearances,
it makes the 10mm nuts on the back easier to replace when the exhaust nuts are off.

Re: Slipping clutch - what should I expect on stripping down?

You're right, Mike, I wasn't sure when the plastic pistons came in, but looking at realoem, it
seems the part can be retrofitted to earlier bikes too, as you say, worth a look before
removing the gearbox, although, OP might want to do an input shaft spline-lube.

Re: Slipping clutch - what should I expect on stripping down?

Hi, Goldie If it's only happening when things warm up a bit, it may be that your clutch actuating piston is expanding and jamming in the housing. Before you do a full stripdown, take out the piston and see if it looks like it sticks when hot, clean it up with some sandpaper or turn it down a bit (or...

I got one for about 20 euros, it plugs straight in and I can turn the output up to 14.5 volts for my Motobatt battery, has been working pretty well for last couple of years....

Hi, Davy
If you haven't got a vernier caliper to measure your fork legs, use a measuring tape ( or a piece of string) around your fork
and multiply the length by 7/22 to get the diameter.
