The trick is that you have to heat the piston using a mild torch or electric heater.
<br>The aluminum has a higher rate of thermal expansion than the steel so the steel will come loose.
<br>make sure to use tools or protective glooves to avoid burns.

thanks joan the bike has now past its mot test and goes like a dream not fast but in a class of its own thanks again kevin

Hi Everyone. This is my first visit having just acquired a 3800 from a 'Troc' in southern France. I'd like to know how old it is, so can anyone tell me whether it is possible to determine the year of manufacture from the engine number?

Its got 3928779 stamped into the crankcase.

Looking forward to hearing from someone soon!

Hello

Klik on bijlage en you will find wat you are looking for.
Greetings from belgium

All the engine numbers using 7 digits are french made, you should be able to trace the information using french web-sites ( the previous message has an appendix="bijlage" which may link you to the right URL.

Dutch made solex' es ( Made by vd Heem under a french license) are using 6 digit engine numbers ( smaller market)
and all have a cast-in designation " v d Heem"
This forum ( drop down menu on starter page - so exit the forum- has a table relating engine numbers to year of manufacture)
