Have you been fiddling with the PE175?
Don't you trust me Dave
No, haven't touched the PE, it runs too well to do anything to it. The YZ is going good now. Changed the carb specs back to standard (ish)
and it's a bit of a rocket. Nothing down low, but that was to be expected.
The PE flat spot has been there for a while, but I've only just noticed it, since I've gotten a bit more confidence and actually started riding a little bit faster. Vandy told me about it at Conondale, but I was puttering around there, so it didn't bother me at the time.
So, I'll up the float level and see if that helps.
Cheers guys
