"Pistoncino"- Down a fuel flavoured rabbit hole

Today I stripped the dellorto me8bs carbie.

For a 49 years of age it was very clean and no fuel varnish.

I have discovered that the choke slide is missing. The arm it attaches to is there. No lever.

The bike fires up first kick when cold. Fuel being supplied from a fuel bottle.

Fitted the cleaned out tank. Well I thought it was clean. Didn't that lead down a rabbit trail of other problems today.

Bike would not run well under load. Will if I just use a fuel bottle.

Stripped the fuel petcock. So much built up gunk. Can of carbie cleaner and got most of it out. Refit still wont run with throttle open. Check fuel flow. Next to none.

Use the other petcock and there is fuel flow.

Then I stripped the banjo nut that holds the fuel outlet tube and the tread for this on the petcock. Wont tighten and hold fuel. Jump on eBay and order a new one. Yes you can for a 49 year old bike get new rep parts.

Now to wait the 3 weeks for it to arrive.

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 combi...

On a Sure Footing....

I love my BMW. More than any other bike I have owned. This doesn’t mean that it is not without its blemishes. Take the hair trigger sidestand. Known to fold up when an Alpaca herder in the Andres sneezes and the bike is in Australia. Many a BMW owner has found their bike on its side on the ground. Fairing broken. The sidestand has folded up into the raised position. Why? Because it likes to. Once the smallest amount of weigh transfers off the side stand it will fly up. Also if you have an RT type fairing as mine does you can not put the stand down when sitting on the seat. Well I can’t with my short legs. I have to clamber off the bike while holding it up right and then use centre stand. I don’t trust the sidestand. This Video shows how vicious the original sidestand is. Click on the play button. That all changed yesterday. I fitted a SureFoot sidestand . Moto-Bins in the UK supply these. They are of a very sturdy construction. Comes with full fitting instructions and 2 new...

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. Unless it was still freez...
