Hi,
I have almost completed a 1981 TR1 for the track. I am having trouble starting it first time. The only electrics on the bike are the charging circuit (to be replaced by a total loss system later), and the ignition. I have three TCI units. All second hand and from 750 bikes. One is not giving any spark on no.1 cylinder, but the other two, I'm not sure.
I have made up an adaptor to turn the engine over with an electric drill (Plugs out). Plenty of spark, just not in the right place.
Is there any difference between the 750 and 1000 TCI units that I should know about. I've been through the wiring diagrams and can't see that they would be different except for maybe a different advance curve. (internal)
Both coils have 2.3 Ohms primary resistance, the pickup's have 550 Ohms resistance and are not shorted between each other.
It may be that I'm just unlucky and have three bad TCI units. I have another second hand one coming.
Any help appreciated. Also info on aftermarket TCI boxes.
Cheers,
Craig

Thanks for the post Stefan. Have found the Czech site.
Tried to upload an image of the bike without success. Here it is again. Maybe.

Oh yes, I would like to know also.
It looks good

After a mix-up with Paypal, I finally received the TCI-P4 ignition unit. Why didn't I do this in the beginning. Fantastic unit for the price, and comes with programming software. Bike is running now, but wasn't easy to start at first. I tried to use the charging circuit only. You have to spin the engine quite fast to get up to 8V. (8V - 14V is the operating range for the Ignitech unit.) Alternator windings and regulator checked out fine but may be the magnets loose some of their oomph over time. So bump starting wasn't an option. All was well when I fitted a battery.
If anyone is interested, I started asking questions on the "Viragotech" web site in "Tech Help", so you can see the history and outcomes. Had to work it out for myself in the end.
Happy Biking
