Not everyone is aware that a simple bench grinder can be quickly turned into a metal polishing too and some restorations parts on the bike can be made like new in a few minutes with this tool.
If you had enough parts to repair/restore then you can bundle them up and take them to be replated and pay for it too and then wait to get them back, that is a good process but if you have only a few bits or just like doing as much of the work yourself then get one of these going in your shed.
This one is a cheap grinder bought at the local hardware store, remove the grinding wheels etc and add on the required shafts, buffing wheels and buy some polishing compounds, I got all my parts from my local Bunnings, very simple to do.

It is simple to use and you can see result below, these 2 metal pieces were identical, both slightly corroded after 40 years, I polished 1 for about 60 seconds on the wheel, the difference is instant.
One of the hardest parts to find for the Suzuki TM125 was an intact magneto cover that still had the bolt holes to attach the sprocket cover to….. very rare. Chain throws were so common back then that sprocket covers must have been flying off everywhere.
After nearly 12 months searching I found one on ebay that someone managed to do a good repair on, painted up it looks all ok as the repair is on the inside, the sprocket cover fitted on nicley, finally finished the bike.
For those who need to get your old vmx tank restored, you can do well by talking to your local auto body shop. I sent this old aluminium Yamaha YZ360B tank that was once on a USA yellow model to my guy Zac in Perth (0404 253 260) and he did a great job in repairing, smoothing and finishing the tank in white, very impressed by his work and the price was more than fair.
Next step was to find some new graphics, only problem I could not locate any at all for the Euro white model YZ360B YZ250B. There was some on ebay for the yellow model in the USA but not the white model. The solution, I went to my local sign shop and gave them an original tank that had the Yamaha graphics and my newly restored white tank, hey presto, 2 hours later they rang for me to pick it up – all finished and looks great. These guys have the digital artwork on computer now and can print out as many copies as they want if you need a set for your white tank.

At one time or another, you’ve sat around with your friends and jabbered about the mythical “composite” motorcycle. You know the one -it’ got the peak horsepower of a breathed·on Pursang, combined with the low-end grunt of a Stiletto. It`s got the plush forks of a Maico, turns like a CZ and tracks like a cut-frame Husky. It weighs less than a good 250 and has the punch of a 400. And the best part-you don’t have to do anything to the bike. just ride it like it was a 350 Honda pseudo-scrambler.
We’ve all dreamed about that kind of a machine, but up until now, it never existed.
A quick look around at the competition mounts of the Staff of DIRT BIKE shows what has to be done to make a motorcycle “right” for competition. No one but a fool rides a Maico in stock trim. Different filters, rims and assorted bozos are a must for the serious rider. Continue reading
Mono-Mania – THE OPEN CLASS ULTIMATE
’75 Yamaha YZ Monocross by the Staff of DIRT BIKE
Let’s skip the old format for a dirt test this time, and put the conclusion up here – first. That’s breaking a precedent, but the YZ Monocross breaks precedents too. OK, here’s the conclusion: This motorcycle is THE ultimate weapon right now!
Oh, it’s got stuff wrong with it. It’s not the traditional maintenance-free Yamaha of the past. But even if the motor fell out of the frame once every day, it is still the finest racing bike you can buy, right now.
And this is why: It’s got power.
YZs always had power. So does this one. It comes out of the hole and out of the corners like a greased, goosed grand prix race car. It is screaming from the moment you crack it open. It breaks the rear wheel loose in every gear. When you’re on it, your favorite track gets shortened by what feels like 20 percent. Everything comes up sooner than ever before. See that corner up there? It’s here. Right now. Continue reading
The seat on my 75 CR125 racer was not suitable, the cover had a few holes and I didn’t like the high GP foam style. It looked old on a restored bike.
A search on the web found a company on ebay and also listed on the general web called Hondaclassic 31 which makes brand new vmx seats for this model, new metal base, new foam, new cover and all assembled ready to bolt on… all for only US$150 plus freight.
They delivered it in short order and although it needed a few small spacers on the rear to align the bolt holes, it then bolted straight on, very nice.
