General Discussion / Re: Necessary to Remove T3 Master Cylinder?

« Last post by moto on Today at 09:06:06 AM »

Can the T3 upper master cylinder be rebuilt while attached to the handle bars? I was planning to knock out the old cylinder and then press in the new parts using a socket and large C-clamp to seat them. I can't easily remove it because the switch is wired through the handlebars. Will this be more difficult than I imagine?

I think you must mean the stoplight switch. But it is not wired through the handlebars. It operates from a hydraulic junction below the headlight on the front fork, plumbed into the front brake tubing.

Oh, I don't know.  I'm still scarred from bleeding the I-abs servo system on my old BMW K1200gt.  SIX! (count em...6!) bleed valve nipples on the servo itself, plus one more in a line junction, plus the usual one on each brake caliper for a total of 10!

If that doesn't confirm the old German Engineering adage of "Why use just one part when 37 will do!" I don't know what does.   

You must have the old ABSII brake system, like my 2002 K1200RS, worse ABS system ever designed....it's a freaking horror show for sure....LOL!

I guess it's possible to rebuild it on the 'bars, never tried it myself.

I've been asked that question more than once and really don't have a good answer. If Lino Tonti was still alive we could ask him...

I spoke with Greg at This Old Tractor and he said about the same. He stated he didn't think the 6mm difference was that big of a deal and to try it with the bearing snap-ringed in place, so that's what I'm going to do, I made a 6mm spacer so I'll put that on the outside of the bearing between the nearing and axle....easy enough to reverse it if needed down the road.

Theoretically, a 100/90-18 is 25.1in i diameter. A 130/90-16 is 25.2in, so marginally larger. A 110/90-18 is 25.8in in diameter.

You can play all day long here https://www.calculator.net/tire-size-calculator.html. I like it because you can compare two sizes at once, and you can change just one value at the time without putting in all the information over and over.

Ive used those tire calculators a few times for both this custom and also my V7 III enduro build, when I was deciding whether or not to build an 18” rear. Anyway, I’m planning to go with an 18” for the classic look and to make it lighter both aesthetically and physically.

i've got a morini dart , looks like a tiny ducati paso ,


 it is basically a 125 cagiva 2 stroke chassis where they managed to shoehorn a 350 morini engine in.
as the chassis was meant for a two stroke it does not have easy access to the engine.
to check the oil level you have to completely remove the fairing.
typical of italians ,
build beautiful things, but practicality not at the top of the priority list.

« Last post by Kev m on Today at 04:35:54 AM »

It's been discussed here over the years.

Some have had success addressing the harness and/or grounds:

Dash voltage reading vs. at the battery... https://share.google/3RrFKzbrSLeTIlxEn


Some looked deeper at the circuits powering the dash and any other components that might affect the reading:

Others just lived with it.

General Discussion / Why spline lubrication?

« Last post by faffi on Today at 04:11:56 AM »

Especially BMWs seems to require spline lubing of the clutch shaft splines as well as final drive splines. But we never hear this about cars. Well, at least I do not. Anybody know what this is required (more) on bikes than cars?

While time-consuming, a real PITA and with a real chance of someone stripping threads in the crankcase by over-tightening the oil pan bolts, there really is a sensible reason for this; you can both inspect the bottom of the oil pan for things not supposed to be there AND you can - and should - clean it out before refitting.

Now, being lazy, I very much prefer a drain bolt over oil pan removal and accept the lack of inspection and cleaning. Another danger with such an elaborate system is that quite a few will be tempted to prolong oil filter changes.
