removeing electrical componts..

If you look at the attached pic, the small loom inside the white "loop" came off a functioning TTR so it demonstrates the minimalist approach compared to the full Euro loom spread around it.

It includes connections for the CDi, ignition coil, regulator/rectifier, two earth wires (pair joined black wires and a single white wire), ignition kill/starter switches, and the ignition pulsar (can't recall the correct name ).

Sorry it doesn't answer your question but it is interesting to see how little is needed for the TTR to run.

Removing electrical components..
Permalink  
 

So I'm thinking of stripping the TTR of all electrical components as I never use it on the road..

keep battery , starter & charging components , all other stuff will go...

Question ... to remove the ignition switch do I have to connect any wires in the main loom ?

only want the kill switch & a main on/off switch...

If you remove the main switch, there will be nothing to turn the headlight, taillights, illumination, etc. off....

You will need a switch of some kind to turn the lights off, unless.... you hook the lights up after the ON/OFF switch. Basically, you would unplug the lighting circuit (red wire leading from the rectifier) making sure that the red wire that you unplugged joins to the brown wire leading to the ON/OFF switch and then join/bridge the lighting circuit to the red wire with a black stripe leading from the ON/OFF switch.

 There will be no lights/speedo /blinker /etc .. as I want to remove all electrical componts..

I'm only useing it for trail rides & enduros.. so strip it out.. put the YZF forks in... the TTR

makes a good little non competitive play/enduro bike.. now with the GYTR & Brian's header pipe

, the air box mods  &  Rekluse clutch that little motor has taken on a new lease of life.. and I don't

need to rebuild it every 100 hours..

years ago when I was raceing TQ midets... the Honda CB750 motor you could

unrap the loom  make 3 cuts & ignition section could be removed the 3 cut wires

were earth , kill switch , power in..

maybe possable do simular with the TTR loom..

 Would be interesting to see the TTR s frame with the least amount of wires to keep it running.

 If you don't want lights then it is easy... Just cut the lighting circuit from the harness and leave the rest as shown below in the diagram...

Hi Pete

Sorry for the slow response. Have had "gents" problems and have spent much of the week in and out of hospital. Not a very nice experience and I won't be riding for a week or two yet no

I have kept the cut-down loom more for interest than anything else. I am always impressed with anyone who knows their way around TTR electrics and the person that cut back the loom is on my list! 

I will put it on the scales and email you a price to include shipping. No point in re-inventing the wheel eh?

Cheers

Brian

From looking at Brian's picture- YES, it does still retain the starting circuit and the charging circuit.

It is very easy to do as has been done in Brian's picture, I could do it with my eyes closed (well maybe not with my eyes closed but yeah lol).

I'm going to be doing the same as the OP and removing all of the elecrical components I don't need for trail riding. Would be great if I could buy one of these minimal looms - are they available?

So I've taken my loom off and am going to chop off the bits I don't want. If I remove the following bits will the bike still run?

- Indicators
- Handlebar lights / horn control unit
- Headlight and brake light
- Brake light switches (lever and brake pedal)
- Clutch switch
- Side stand switch
- Neutral switch
- Horn
- Speedometer
