Hi fellow 2 stroke enthusiasts,

Like many here I guess I have had 2 stroke since a very long time, first with mopeds then minitrail and then much bigger motocross and snowmobile ones. I actualy learnt English by reading a 2 stroke work shop manual at 13 years old...

But then bigger and stupidly fast 4 stroke sports bikes lured me away.

The thing is once you start trying to understand them and and make them faster 2 strokes are a strong addiction !!!

I got back to it with a shop I would not even dream about as a kid rebuilding the bike I dreamt about as a kid.

Way back then I had a 1981 Suzuki PE 175 but REALLY wanted the 400 !!!

So I built one mostly stock it goes well enough but I want it to be faster than that...

Looking at other similar motors I found that the RM 465 has a bore of only 1 more mm but 10 mm more stroke and a nice big reed valve intake that I like much better than the piston port / reed contraption ef the PE.

I bought a 465 cylinder of ebay and got to work.

Redrilling the base studs holes:

Seeing that it does fit but will need some welding:

This screw will be made shorter and it should be ok.

But so far so good and I like the way it looks.

I will probably start a new thread in the Suzuki section to describe the rest.

So thanks for all the info on this site and if you need anything translated from french I'm there.
