Well, even a detuned Bandit make 98PS and just tons quicker and faster than a stock TR-1, so obviously you've got some stomp in your engine.

The oil-level-switch has been dead(-ish) since pretty much when I bought the bike ten years ago. After having a VERY close look myself and admittedly seeing it on another TR1, I figured that the odd dimple right underneath the starter on Gen1 engine cases is actually meant to be drilled out and tapped as it goes straight into the main oil-gallery.

And that's pretty much what I've done today, as the oilchange was due anyway. (That said, you only have to take the right engine cover off, so you could do it withou changing the oil, but it could get messy...)

I'll put the hi-res pictures on my blog and update this post once I have done so.

The oil-pressure switch is a generic item with M10x1 thread, mine's meant to go in VW Vanagon 1.6TD. Unfortunately it's a closer at 0.9Bar (12-ish PSI) pressure, which is pretty much spot on, except for the fact (as you can see in the last picture) the light's always on, when there's pressure in the system. So, I'll have to get that one swapped out, next time I am close to an autoparts-store.

Funnily I noticed that boss today and wondered about it ( I managed to swap the crank and put the gearbox back in today which means it is more together than it was when I bought it!! wohoo!!)

Let us know what switch you end up getting that works as I might just do that myself.

Cheers,

Right, so I've gone and got myself a Facet 7.0008 (0.3Bar) switch, which is normally closed and opens under pressure. The perfect switch would be a Facet 7.0119, which starts to open at 0.5Bar (7PSI).

The reason being the colour-code blue Facet 7.0008 is standard on nearly every VW engine from Golf to Transporter and has been since... literally even though back then it was the colour-code brown 7.0108, but all other specs are the same.

I am pretty sure, if you're in the US you would want to go through the catalogues and find something from a car, which is more common and will then have a different thread. (VW-stuff is M10x1)

Still, works a treat for now and I'll order the other switch in the coming weeks and put the current one onto the turbo-engine.

Nanno, what brand of filter would you suggest? I found a nice round K&N pancake I was gonna buy (RC-1950) but after reading your post about the mesh being to course I got a little worried.

Not too rude, I'd say. :bg:
Nope sorry dude, can't really say. I've built the exhaust for a friend's 750, which is also why all the tube diameters have been scaled down. Additionally when the guy wanted to start the bike on Tuesday, the starter failed. So it'll be a few more days until I get some feedback from him.

That was only referring to petrol filters, not air-cleaners.

As this won't fit anywhere else in my opinion, here's a couple of things I decided to change on my TR1 and see if they can improve the everyday-ability of the bike some more:

1) When riding in rainy weather a lot, the rear brake pedal tended to get sticky. Not enough to really seize, but it was annoying and with my rear brake being adjusted properly this can quite quickly lead to a locked up rear wheel in the wet. No fun.

Image

So this is the solution:

POri0WTY4CucvL6jt7udwZAEbbKX0QCLcBGAs/s1600/IMG_2985.JPG" alt="Image" class="resize_me" />

That, by the way, is a shaft that had been freshly greased up three months ago. (Yes, the weather was mostly awful.)

Image

Cleaned up thoroughly, drilled and tapped

Image

Image

2) my gear-lever is proper wobbly after doing about 120,000km (70,000mls) and needed some proper bushes with added shoulders so it would stay aligned better. (Dimensions: 24mm barstock turned down to 16.0mm, 19mm wide, 10mm centerbore)

Image

CCHvEssh_nVTuQUeKg-TAVPppTgACLcBGAs/s1600/IMG_3005.JPG" alt="Image" class="resize_me" />

And that's half-assembled to give you an idea how it's supposed to work. (Obviously prior to greasing it up.)

Re: your 2 into 1 exhaust - very nice! I'm curious as to what you used to make the flanges that seal against the gasket at the heads? I don't have a lathe so I'm wracking my brain trying to come up with something I can maybe "trim" by hand to fit... first thought was a piece of sched. 80 1-1/2" pipe but it's about 1/4" too small on the O.D. and would probably not seal well on the gasket. Other ideas are large nuts, and most recently (having seen your pipes) large washers that I could possible grind/file down to fit. I do have a set of stock pipes, but they're in really good condition and I don't want to cut them up if I can come up with a reasonably simple solution....we have 4 other Viragos in our family that those pipes could be used on if needed in the future.

I hate to break it to you, but I do have a lathe... :r:

An easy way out were to draw up a ring in CAD and just have it water- or laser-cut at a shop. (That's what I do with a lot of parts, because (free) time is starting to become a bit of a premium item and the parts often end up being as nice as stuff that I make myself on the mill and lathe.)

Oh well...I took a trip out to a local machine shop this afternoon. $80.00 for a pair of them. So I stopped in at an industrial supply house on the way home and picked up a 1-1/2" nut. Four hours later after using up one hacksaw blade, the use of a 1-1/2" hole saw to clean out the threads, a 14" smooth file and my bench grinder, I have one ring at a cost of $3.88. I'll pick up another nut tomorrow....as an old retired guy, I have more time than money. :-)

Sounds good with me. I pay approx. 4-5 Euros per ring at my waterjet cutter...
