Thanx lowriderb for putting the pictures on for me.

 

So what you guys think? Paul at vito's sail that there may be an internal water leak from the cylinder head gasket that could be washing the oil of the bores. If the tops of the pistons have fine patters of marks (like spray marks) that have caused silver spots (burth off the top of the piston crown) it could be a water problem?

 

I had the crank replaced 3 1/2 months ago when all the seal where replaced, no to say they havent gone again.

 

The crank was fitted by a bike technician that works for the police force.

 

Any comments now you can see the melt down patterns would be welcomed.

Please look at the pistons and offer me any advice you can think of as I am certainly not a clued up as you guys nor is any one else in the UK it seems.

 

I have had some good advice so far but the more things I check the more reliable it should be and with my intent being to race next year I have a very steep learning curve to follow.

 

Do the spray patterns on the top of the pistons look as if they are caused by an internal water leak?

 

Some people a telling me to get rid a the 2 stroke and buy a 4 but I love the way it sounds and goes (at least when it not in peices) so please, please help me out on this one guys.

 

Thanks

re: 'they are supposed to be exactly the same.. '

 

And...when they are not?

 

Thanks for the humor! :laugh:

 

From this we learn that this Banshee does NOT have a seized piston. Just look at the piston on the right in your pics. IT'S not seized, they are supposed to be exactly the same, so by the above fine example of erudition, we KNOW the other one is not seized either!

 

That's stoopid, isn't it. And it makes as much sense as 'Jet them both the same all the time because they are both the same all the time.'

 

Think outside the tiny little box. Because 'I always..' 'I never...' 'I haven't....' or 'I won't...' is no reason to NOT consider the very real possibility that there may exist fact outside of what you know.

 

..and the Banshee doesn't even have a rotary valve! Imagine!

 

 

Lectrons are obviously junk, it being said, 'I have never used a tapered bore carb...' makes that pretty obvious.

 

FWIW (nada), my carbs are taper-bored..and they even have the same jets in 'em, right and left! :shrug:

I have a mortgage, mouths to feed and a girlfriend who cant see the fascination in quads and most certainly cant understand the large chunks of money that are coming out of the bank account (just before our wedding in August) to keep this hobby going.

 

Please give advice.
