Hey Cuddly, went and met an old KLX650"R" fan today that invited me to come and have a ride on his bike. He was interested in my electric start conversion and I was interested in his engine mods. My bike is about 48 - 50 hp and he said his bike runs on the dyno at 65 hp at the rear wheel.
He gave me lots of info, he owns a Kawasaki dealership a few hours away. His bike just sits in his shed now with a sheet over it.
Cheers Fogo...

Is the wossner piston necessary?

Hi Fogo: You wrote about your bigbore with a Wossner piston. What are the advantages to this piston as opposed to the Vulcan 1500cc piston used by others? Has anyone bored and sleeved an R cylinder to accept a big bore?

Thanks

Todde

I have never used or seen a vulcan piston so I can't comment, but a few months ago my bike blew a head gasket and slowly dumped its coolant out the exhaust, I didn't know at the time, I was chasing down a friend in front of me and held my bike flat at 170 kph for about 10 klms and the engine started to get tight and lose power I backed off to 80 and let her cool down then came to a stop to investigate. No rivers or creeks anywhere so I rode it home about a distance of 40 klms. When I took the top end apart to investigate there was not one score or scratch up the liner or on the thrust side of the ceramic shirt of the piston, bloody brilliant, there, proven quality right there. Standard piston and rings are crap, any predetonation snaps out the ring land of the 1st and 2nd position while constantly slobering into the air box unable to control the oil on the cylinder wall and hold back the combustion pressures. For a career I am a mechanic that specialises in high HP electroniclly controlled diesel engines over 2400 horsepower, so after 20 years I have managed to learn what the ass end of an engine looks like.

As for the rebore of the "R" whats the problem, Lock it to a boring bench, send the boring bar down through it to the correct size to be an interferance fit and press a "C" model liner straight in. LA sleeve in the USA were selling them for about $75. Done, easy.

Your call buddy, its your bike, put what ever you want in it. Your best tool is
Cheers Fogo...

The inmate to talk to about the Vulcan piston is Mark 53, either here or on the KLX site on Yahoo. He posted a lot of info on the Yahoo site. All I remember is the piston is of standard design vs short skirts for the Wossner. There seemed to be an initial concern about placement of the piston pin may increase side thrust and some question of the valve cut outs for clearance. I seem to remember he measured the head to determine clearance issues and potential CR.
It seemed to have worked well for him, as he has thousands of miles on it and is an advocate.

There also people using a xr600 hotrod and a wösner 102mm

because the xr rod is stronger.

Where is this info from? I have been on the Yahoo list for a long time and never read about that. Is there some other source of info?

I am probably going to rebuild my KLX sometime soon and am looking for as much info as possible about it.

Has anyone had issues with the starter clutch on these bikes? seems as though mine is on the way out. it seem to be iffy at engaging when starting and also sometimes seems to engage while the engine is running causing a horrible racket from the left side of the engine (atleast i hope its only the starter )

I just got back from a 981 mile round trip on my KLX. I am now going to go out, shoot that seat and bury it in my neighbor's yard.
