Hi Guys,

I'm Steve, a new member from Adelaide, Australia . I have been reading the posts and I just wish I had found this forum earlier. You guys are really great.

I bought my 71 T120R about 12 years ago. It was a roughie but has matching frame and engine numbers. Currently it is on the workbench as a frame and wheels. The engine is at the mechanics. As the engine progresses my thoughts have turned to starting to put it back together. The problem is, I don't have a clue where to start. Are there any books/video's etc that could put me straight ?

I'm talking about electrical loom/coils/etc being put back on the frame so it is ready to just put the engine back in and reconnect it all. Hope you can help

All the best,

Steve

Make sure you have the factory manual and parts book. With these two, the rebuild should be quite straight forward. Personally, I leave the wiring loom until the engine, rear mudguard, rear light housing, handle bars, chainguard etc are on. This is because you may need to adjust the position of the loom on the frame to make sure everything can be reached. Then cable tie the loom to the frame. Finally you put on the cables petrol tank, seat, headlamp etc

Welcome, TriNut.

I like to assemble the rolling chassis first, without brake pedal installed, but with front brakes & fenders.

Then, I install the complete engine with kickstarter to assist in handling it (best done as a 2 person job). On pre-69 engines, you first want to tip the engine over and connect a 3' length of oil-resistant rubber hose to the breather connection hidden way up inside the engine sprocket cavity; trying to do this with the engine installed in the bike is a nightmare.

Next, install the carburators, thottle & clutch cables, brake pedal, shifter, drive chain, oil tank & oil lines.

Now, sort the rolling assembly for proper operation of all the controls and that the engine can be shifted cleanly through all gears while rolling the bike. Ensure that your cable routing is as clean and smooth as possible with no binding or sharp bends.

Now, install the lights and electrical componentry (coils, ignition, charging system bits, switches, etc).

Next, carefully route the main wiring harness, making sure not to interfere with the cables, especially throttle & choke (if connected). Connect all of the devices and ensure that each has a bit of slack so as not to pull any connections loose when handlebars are turned, etc.

Static time your ignition system.

Install gas tank & fuel lines, battery with breather hose properly routed below and behind the swingarm pivot, completely clear of anything that could be damaged by acid drippage.

Pull out your spark plugs, re-connect them and lay them on the head, turn on your key and cycle through the kickstarter. Make sure you have a good spark at both plugs. At this time, check the operation of your kill button! Replace plugs.

Top off all fluids, set up your start-up / test area with a large fan, timing light, small screwdriver for carb adjustment, and allen wrench & small wrench for adjusting ignition. For strobe timing, you really will be better off with an assistant. Do your start-up with the fan pointed at the engine, check to see that you have oil return by looking in the oil tank filler hole; make sure you nip up the ignition stator plate, and set your carb idle screws.

The rest is detailing and can be done in almost any order.

Have at it!

Hi Steve,

Welcome to the forum. You'll find there a quite a few Aussies here.

Post a few pics of your '71 and show us what she looks like.

Thanks for the replies guys, i really appreciate the help. This started as a tidy up many moons ago and has grown bigger than Ben Hur.
