Zeke - CDI box dead.

Transalps have a few known problems. CDI box failure is one. The seat base over time drops and rests on the CDI boxes. This can cause damage inside where the connectors are soldered. The solder cracks causing the connectors to be loose therefore not allowing the flow of electricity.

2 weeks ago I ordered a new CDI from the States. I am still waiting for this to come in the mail. Today the bike would not start. No spark to rear cylinder. Swapped the CDI boxes around just to make sure this was the problem. Start up and the rear now has spark.

I could wait a few more days for the new CDI to arrive or have a go at fixing it. Youtube has a few videos on how to do this. Crack the box open on the other side from the connectors. Re-solder these. Tapped up the box. Connected up and the bike starts and runs. Temp fix done.

It is also suggested that the Honda CDI relocation bracket be used to get the boxes away from the seat or do as i did and bridge the frame. I used some L shape metal bracket cut to fit and the seat sits on that and does not touch the CDIs.

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.
