Steady on A-J, i'm still trying to get my head around the basics, let alone "tweeking" anything yet
After my first attempt at (ahem) modifying shall we say, it didn't quite have the desired results
Moving swiftly on then....
the mark 2 version is currently at the measuring and evaluating stage. Now i know which direction i want to go with this i can start making enquiries into getting bits and bobs "trimmed professionally" and CAREFULLY....
I'm working on the theory of less is more.
I have read and re-read different chapters in various books and come to my own conclusions on some things. Others out there will have their own thoughts too.
FRICTION..... often the scurge of 2 stroke engines as it can sap power. After my last attempt, friction was the killer factor that "cooked" the crank. Mind you, the crankcases being completely out of alignment didn't help either.
So the "mark 2" has a (rather sloppy fit) replacement set of second hand cases. Loads of crank end float as you'd expect (around 1-1.5mm as best as i can measure) sounds a lot doesn't it? I'm not that bothered, as long as nothing spinning within isn't binding up to provide the heat then that'll do for me.
Then there's the piston. Perhaps the guts of it all as it has to do all the hard work. Again, not a tight fit.... more on the loose side. (less is more)
Measurements on the port timing seem to be within specs (after conversations with the "master") although still a bit of room for improvement.
Baby steps all the way.
A little here, a little there, then test.
As for running rings, lets just hope for a comfortable mid field runner.
All good though, learning lots along the way.
