Claire at French Touch Upholstery, you can get her on Instagram @Frenchtouch_upholstery.

Sheís done a great job on them, full prototype from start to finish Think sheís on Facebook too.


Thanks for the info. How much was it?

Hmm... youíd be better giving Claire a shout, I paid a good bit more for it during the prototype phase and had her make changes along the way so mine wouldnít be the best representation of the cost. Iím not aware sheís made any others to date.

Iíve had endless starting issues of recent where the bike would just crank and crank but not fire. After reading countless posts about similar issue where people then cleaned ignition, pulled apart altanator and starters etc I then read one single reply from a brick owner who said that every time he had this symptom he bought a new battery and it rectified the no start issue. Although my cheap 14ah 12v lead acid battery could turn the Brick over with ease, I became tired of charging it if the bike hadnít ran for a week or two.

After further research I decided to purchase a JMT Lithium-Ion Battery hj51913, apparently this unit only looses 5% of charge per month if shelved and also has a handy triple light test button which indicates the charge level but the best part is that it only weighs a little over 1kg! The bike starts from cold at immediate touch of the starter button now. The only downside I understand, with the exception of the cost, is if the unit is completely discharged then the cells are often non recoverable.





I also purchased a one litre Ďfuel friendí which is strapped to the battery behind the altanator and starter (no touching surfaces and plenty of air movement still)



My OEM BMW fork seals have also arrived to replace the bran new annoying as hell leaking pattern part ones. I also ordered a set of LSL street bars, these are 820mm wide so will offer a more stable almost R Nine T position over the original 660mm stock bars. Iíll change out the fork seals and bars together in the coming weeks.

Hi Gary, no, I donít own one... yet. Iím going to see how it goes with the Lithium Ion, monitor it and trend it over a while, Iím hoping if theyíre as good as they say they are that it wonít need a trickle. Iím unsure what the usage is from the digital clock on the Acewell but Iíd expect not much?

Correct! She got to £3800ish on fleEbay but I pulled the advert with 6 days left and over 370 watchers. I only considered it as I nearly had my hands on a 1996 CB 500 which was my first ďwantĒ but in the end decided to continue modding/perfecting ĎTriple Sí. Iíve only got a 3x3m space so no room for companions. I think the starting/electrical niggles were the main driver to get rid but the procurement of this new battery seems to have got rid of every start problem, sheís not missed a command since.

The only outstanding issue I seem to have, with exception of the leaky fork seals, is that the fuel light is still permananently on, on the Acewell CA-85. The Acewell and BEP 3.0 senses the level easily with 1985 (pre float) electronic sender and it should indicate a fuel light at 7L... Those of you who have followed the build know I got a replacement BEP but I still have the light issue, and some of you will remember I replaced the fuel sender too (which ended up being dodgy) and I still had the light on with a full gas tank. Jumping back to page 6 of the thread, Martin explained the active high/low circuit, quoted below:

Yes, the BEP 3.0 has a circuit to sense 7L threshold on the pre-85 fuel sender and trigger a lamp.  The signal is active LOW meaning it goes to ground potential when activated.  This only works with inputs on the CA85 that are also active LOW.  Acewell is not specific in the manual whether the low fuel light is active HIGH or active LOW.

Does this mean that the circuits could be the wrong way round currently? Iím no Electrician...

Active high / Active low signals
Some indicator lights on the gauge activate when a +12V signal is applied to the wire.  This is termed active high.  Opening the circuit will turn off the indicator.  Internally to the gauge, the LED cathode is grounded.  An example of an active HIGH input is the turn signal indicator.

Alternatively, some of the indicator lights activate when they get grounded.  This is termed active low.  Opening the circuit to the input will turn off the indicator.  Internally to the gauge, the LED anode is connected to the +12V going to the gauge.  An example of an active LOW input is the oil pressure indicator.

Does the fuel light go out when you've less than 7 liter in the tank? If so, yes.

Iím all set for installing genuine fork seals this Saturday along with the LSL Street Bars. Iíve also looked out the old shock boots, inspected them and they are in great condition so will clean them up but Iím on two minds whether to install them or not? Any top tips for the install?

To lengthen the life of your seals pack silicone grease under the dust cover. It's not as important as you're fitting gaiters but everything helps.

Thanks, Martin, I'll do that.

Sure, Laitch, I'll get some photographs tomorrow. I'm not understanding the diagram you have posted, will have to review the Acewell wiring diagram.

Brilliant! Where did you come across this, Laitch, I've never seen such a diagram?

In the office right now so have no access to take a clear image but here's one from earlier on in the build, on first glance there is a bit of a disconnect from what's in the diagram you posted VS my current terminations, all function with the exception of the fuel lamp.

It's for a CA085 rather than an MA085. It came from cafe4racer's Marulab BEP download section.

In the left column, where do the blue WRN wire and the yellow G4 wire terminate? Based on my interpretation of the diagram and not knowing your answer to my question, I'd swap the positions of those wires in the left column array but only because it's your moto and the consequences are an ocean away. :giggles

My gauge is the CA85 but that wiring diagram you posted doesnít seem to align with the wiring diagram that came with my gauge, Iíll need to have a search through that C4R downloads section.

The yellow G4? Iím not sure Iím following you, Laitch as there are no gear positions (G4) indicated anyway- yesterday I tried both Yellow A and Blue B both terminated to BAR with a full gas tank and still had an illuminated light, I even tried them both together to no avail.

Iíd love to ride the bike around the North Coast 500 but I donít quite fancy it without the fuel level indicator  :giggles

Yesterday the stripdown and change-out of the leaking pattern part fork seals for OEM ones and the installation of the fork gaitors was a success, do not buy PYRAMID PARTS fork seals, most of you already know that. I wasnít sure I fancied running the fork boots but now theyíre on I think they flow with the black line of the bike just fine. I was surprised at how filthy the fork oil was.










What do you think of the fork boots and new bars?



The installation of the LSL Street Bars was mostly a success however the standard (naked) 170mm upper brake hose wasnít long enough to meet the master cylinder in its new wider position so Iíve ordered a (high handle bars) 250mm one which should fit OK as the new position measures 220mm centre to centre. I really like the initial feel/position of the bars, feels more planted.
Unfortunately the internal diameter of the LSL bars doesnít allow for the original bar ends so Iíve ordered some replacement weighted ones to fit the new 13mm ID.

There were many fasteners that didnít come with the Stainless Steel fastener kit(s) I used during the build so I individually polished the original screw caps up on the abrasive wheel, treated, coated then re-installed. I live on the coast in Scotland so it hasnít taken long for them all to corrode again- yesterday I individually pulled every rusty fixing, measured and ordered a replacement in stainless steel - yes, should have done this in the first place, you could call this anal but itís annoying as hell when the rest of the bike is immaculate, the rusty fasteners just let it down

Your gaiters look stellar, and better yet, actually perform an important job.
The bars are very reminiscent of what we used to sport back in the late 70's, early 80's (Superbike bend) remember the BOTT and Dave Emde, or Lawson levering the Kawi over in lurid 2 wheel drifts? I think it's more authentic than the strap-ons so popular with CR's, although I did clamp on Tommaselli's to lay on the tanks.
Have you considered a small rectangle of heavy mesh to protect the center of the radiator from stones? Looks like it's the natural debris line from the pics.
Nice effort, now for some proper rearsets and a Micron Oil Additive sticker. ;)

Thanks, they have grown on me overnight, I think they are actually quite fitting in the direction of style the bike went.

Wish I knew who you were talking about, Iím just 32 and motorcycles are very new to me!

The radiator is meshed, itís way back in page 3, I actually have the front fender from the other bike, considering cutting it similar but further round at the back:
