RE: Saito 125 poor performance problem
OOPS!
I just saw that you did write it is the YS1.10FZ-S...
They probably hiked the C/R a little, to allow the engine to run properly on a bit less nitro...
But from what I am hearing, the the 'bottom line' is that the FZ was a better engine than its supercessor FZ-S.
The old saying 'If it ain't broke - don't fix it' was apparently not followed by YS...
After all the boogaboos with the first batch of 1.10FZ engines (airbox gasket?) were overcome, it had become a very good engine to own.
...putting it in the 'ain't broke' category...
So, why did YS select to 'fix it' with the 'S' model?
