CL450BB..Rusty nuts no more...

Rust and chrome. Shudder.

I had been cruising through the net reading different forums about restoring bikes. Came a cross a thread where a guy said he could get rid of rust on chromed parts. He was dipping them into oxalic acid. I thought yeah right. He and a few others in this thread said it worked. So I hunted some down. I will give it a go. If it doesn't work I have only wasted a few doolars.

So I went and bought a bottle of Reviva http://www.intergrain.com.au/reviva.html which is mainly oxalic acid. This is used on wooden decking etc. It draws the water out off the wood. So it should draw rust out as it is water reacting with metal.

I did my exhaust nuts.

Before. You can see the rust in places. I did clean this with some kero as well to help get the road grim/many years of grim off them. 


I let them soak in just about full strength Reviva for 24 hours. 
You can see where it has eaten the rust away and left bare cast iron. It works to a degree. Sure makes the chrome shiny again. 



The fleshy looking stuff coming off the parts is rust. These parts had been in this for no more than 5 minutes when I took this photo. 


Here is a very good footnote from off Chop Cult forums.....

You probably know this from researching it... but if not and for others curious, keep the acid away from aluminum or it will eat it up with a quickness. I don't know if they mentioned it... but it's a good idea to spray those parts down with or dip them in a mixture of water and baking soda to neutralize the acid after the cleaning... then give it all a nice oiling, if you aren't going to paint to prevent flash rust or you'll eventually be back where you started from.

Tuning 40mm BING CV carburetors for BMW motorcycles by ear.

Steve Doyle has put together this great and simple guide to tuning your Bing carbs. No need for expensive tuning equipment. So over to Steve...... Any feed back on this How To please email me and I will pass it onto Steve.

There are 3 common methods to syncing the carbs. They will all work
1. Shorting the plugs. http://bmwmotorcycletech.info/synchcarbs.htm and http://www.airheads.org/content/view/216/98/
2. Using a manometer of some sort. Carbtune, Twinmax or home made http://www.airheads.org/content/view/183/98/
3. Using your ears. No comprehensive articles that I could find..

In the spirit of learning to service and tune at home and after lots of reading, I decided that for me the "by ear" technique might be the most useful, as it doesn't require any special tools and can be performed anywhere. There is no risk of electrical damage to the bike or the one doing the adjusting.

It was very difficult to find a comprehensive description of the procedure, so using the combined kn…

Ride impression of the Yamaha MT-03.....

Yamaha have realeased their new 660 based single. The MT-03. See I so want one....MT-03 The bike can be had in Europe but not here in Aussie land. I have asked Yamaha Australia if they will bring them in. They said "No plans at this stage to introduce the MT03 in to Australia." To rub salt into the wounds, axxess, the forum admin guy at http://forum.monoconnection.nl/ got to ride one. NOOOO!!! So unfair. He translated his ride impression into English for those of us who will not get to ride this. Thank you mate for doing this for us. So lets see what he has to say.....

Saturday 16 February I could try the Yamaha MT-03 at Gebben Motors. I could try a brand new red 2008 model. After a short instruction and a warning because of the new tires we were ready to go! The first thing I noticed was the enormous wide steer and the upright riding position It gave me a feeling of absolute control and power! The seat was quit hard but not uncomfortable at all.

The petite MZ...

I asked a question on the MZOG • MZ Owners Group if I should call my bike an MZ or a MuZ. I got some very informative replies. One reply was emailed to me with a link to Wikipedia MZ entry.

What really caught my eye on this webpage was this very petite MZ 125 4 stroke water cooled single.



This is what was said about this bike… “MZ currently manufactures a line of 125cc 4-stroke motorcycles using a new and powerful engine designed in-house. The current MZ 125 produces 15 crank-horsepower (11 kW) and almost 10 lbf·ft (14 N·m) of torque. It is a liquid-cooled pressure-lubricated dual-overhead-cam design with 4 valves, high-voltage electronic ignition and an 11000 rpm ignition cut-off. This is officially the most powerful 125cc 4-stroke engine mass-manufactured and has also proved highly reliable. This engine is used in 4 models of motorcycle, all of which share a common frame. The frame is a tube-steel backbone with the engine as a stressed bottom member. Changes in the suspension, facia, …
