Thanks, I wasn't sure if it was visible when clicked on. I can't even see it when I click on it. BTW thanks for your polishing tips.

By way of introduction I thought i would start a build/restoration thread.

I bought it in March 2013 with the knowledge it was a non running, un registered and in Australian rules un roadworthy state.

The previous owner said it had sat for 8 years and the reason he stopped riding it was the oil leaks. So he parked it up and started to collect parts for a restoration that never eventuated.

A number of things sealed the deal for me.
1. Tank, side panels, headlight bucket and brackets already painted.
2. Good frame and unmolested wiring harness.
3. Great new parts including gasket kit, hagon shocks, wheel and head bearings, repro seat cover, second oversize piston and ring kit, indicators and a few more bits.

The obvious issues were.
1. Oil leaks.
2. Rusty forks.
3. Seized front master and caliper.
4. PO could not get it to start for last 5 years.
5. Other cosmetic issues.

Summing up, for the money spent and the oddball factor I thought it was a good deal.
Will catch up on the last 12 or so months on what has happened in the next several posts

My plan was to get it running to see where the oil leaks were and any other obvious issues. So off with the carbs to clean jets and float bowls, which were not too bad.

Hooked some leads up to a battery and turned it over.... Nothing.
Took out air filter which was in pretty ordinary shape, checked fuel lines, confirmed I had spark......Nothing.
Checked timing and it was spot on. Checked compression and things didn't look good. 90psi on left 110 on right dry. Wet test was not much better. So that indicated to me valve train was more than likely ok but there is an issue with rings and or bore.

Not good, but on the up side which you probably can't see in the pic is the lower compression ring siezed flush with the piston which would explain the very low compression on the left cylinder.

Since the compression wasn't that great on the right either, a rebore, new oversize piston and rings were in order.

While the engine was out I thought it would be a good opportunity for a clean up.
So after bore and hone engine and carb bodies were sent off for soda blasting.

While waiting I thought I would repaint the seat pan and re-cover the seat with a repro cover I recieved with the bike.

Once the engine was back I started assembly and also started polishing cases.

Once the engine was back together I contemplated what to do about paint. I would have preferred to leave the engine bare as the soda blasting does a great job. However years of oil stain have not been kind and have left almost a marble effect on the aluminium.

So I decided to have a go at painting it myself.
Several hours of cleaning and masking I was ready to go. I chose VHT cast aluminium.

I was pretty happy with the end result.
With the engine back in and some oil I thought I would do a compression test before trying to start.
Much better 160 both sides.
Next test hook everything back up and see if she will fire.

Once everything was hooked up and some fuel in the tank it fired up and even idled.

At this point in time we had sold our house and purchased another one. So the shed time was reduced to very little due to packing up and moving to the next house.

It was a good time to plan for the rest of the work to be done. I came up with a short list of
1 Exhaust. Headers rechromed and mufflers ordered.
2 Forks hard chromed and rebuilt.
3 Wheels. Rims rechromed hubs powder coated and new spokes laced in.
4 Front brakes. Currently MC and caliper seized.
5 Lots of minor jobs such as switchblock restoration, re painting various bits such as horn, foot pegs etc. Sourcing an apropriate oil filter or adaptor

As wheels and forks will be done soon and to provide stability while the kids are crawling over it a hoist was purchased.

Nice job MVLUV13, considering your move etc.
Did you find the source of the original oil leaks?
Were the original cases painted? I would have thought the soda blasting would have been enough
