Wer hat Erfahrungen mit Gespann- Umbauten?

I'm drivin now for about 5 years with a sidecar on my TR1.
I did let build a Squire sidecar to the bike by Engbers sidecars (EZS)in Zelhem, Holland.They have a website but i dont know the exact url. It is on the German border near Gronau.
It was apr. € 1000,00 for the construction. I bought the sidecar seccondhand.
I have changed nothin on the bike accept a subframe for the sidecar and a sabilizer between the front forks. Now I can drive the TR1 also withot sidecar. It's only half an hour work to demount the thing. In the future I want to change the (rear) suspension. Thats absolutely too soft but it cost a lot of money.
I'm very satified in fact eventough it did take me about a year to get used to that stupide thing on my right.But the kids love it and that makes it all worth wile.
The fuel consuption is nou apr. 9-10L/100km
The engine did lately start to consume a lot of oil. The engine pressure is very high and oil leaks from the airfilter.
I think I have a broken pistonring but if this comes from the sidecar is not clear. I have driven in apr. 35 deg.heat with full load, mounain up on a solo TR1 and that thig became so hot that I had to hang beside the windscreen to get some cooling for myself, but no broblems.
Let us know when you decidet to do it and show some pictures here.
