I've got a related question for the body of knowlege out there.
While dismantling my '74 TS250 to clean out the 33 years of goo I find this resistor looking component mounted below the battery. There's a green wire coming out of it and a yellow wire broken off.
What is the purpose of this component, I couldn't find it on the wiring diagram I have.
Thanks,

That resister device you speak of was to take excess current from the magneto and send it back to ground through the ceramic covered coil of the resister.The ceramic covering acts as a heat sink so the coil inside it doesnt burn out.
This type of (short to ground) system is designed so when the headlight and tail light are OFF the remaining bulbs such as neutral, indicators and brake lamp would not blow from the excess output if the engine is reving. Of note too is if either the headlight or tail light should burn out during use, the same system will dump the extra current back to ground before the voltage spike can reach the remaining bulbs and blow them.
Remember theres no actual voltage regulator unit in this system, so the battery and the resister act as the regulators.

Odin:
My crossover book show the GT185K as using 54410-08100 shoes but no other models listed for that part number. Thanks for the additional model info which is now in my book. Evidently you have a very rare set of shoes on your T200.
There are places that will reline your shoes. Unfortunately there are none in CowTown anymore. You may want to talk to someone in the forklift business as those people typically use the services of a reliner.
If you do track down an outfit that will reline your shoes just remember to tell them that you need linings for a MECHANICAL brake setup, not HYDRAULIC.
Different coefficients of friction involved, ya see......
If you CAN'T find anyone locally in your end of the world, there's an outfit in the UK that will do them. I, personally, haven't used them but they're called SAFTEK and their website is at www.saftek.co.uk
They will probably be able to help you with a reline.

I'd be careful about that, Tuner. Both my TS185 and PE250 had compression releases installed right out of the crate by me. Those CR's saved my butt many a time and I got so good modulating the lever that I pretty much quit using the service brakes on both machines entirely when I had to negotiate a steep hill.....especially if I'd just come through some water or a bog and the service brakes were totally useless.released the little compression braking they had, making for a real fun ride down a steep hill.

That was the advantage of the CR when you opened it....you were NOW allowing atmospheric pressure to work against the piston.....and that works a LOT better than the standard internal pressure/vacuum levels ever could.

RM370
Anyone here know RMs well? I race a '76 RM370 (in addition to about a dozen other bikes) with AHRMA. Recently, I was in neutral stopped and I was revving the motor to clear it out. The bike tried to take off (In neutral!) and then the motor died. We couldn't get it out of gear after that. I took it apart and found that the 5th drive gear had more or less welded itself onto the lay shaft. Has anyone seen this? Does anyone have RM transmission parts, and does anyone have any suggestions to preventing this from happening in the future? Thanks!

What were you running for lube in the tranny, Phaedrus ??
Did you check the quantity of tranny lube when you drained it ??
Just some thoughts.....
Those RM gearboxes are pretty indestructible. My buddy Wild Bill had one of those from new and kept it for about 8 years. He and I rode offroad at least every second weekend for all those years. Neither my PE nor his RM ever missed a beat. For all I know, his RM is still running somewhere......
PS: Bill's previous offroad ride was a TS400 like rngdng has made into his street tracker. Bill thought the RM was a moon rocket compared to the TS....

TS 400
First post on this board so hello to everyone.
I will be looking to repaint my TS 400 eventually back to original blue( non original now) and locate decals and badges.It is pretty much all there and running except for wrong paint.
Any suggestions or where to find a recent paint match?
72 GT 750 eventually to restore .
All help is appreciated.
Thanks Kenneth
