Hi Glen, Yeah ,,
Brett convinced me to try the 19-11 he`s been sold since last year,,
I was running the 18.1-12 and I loved it till the 19-11 came along.
if you put it on, you won`t take it off LOL
your going to love it. you might have to fatten the low end some though,,

The YS 1.7 is the best most reliable smoothestmotor Once broke in,,to date, regardless if you run the CDI or not.
Ihad a low oil1.7 I ran 8 cases of fuel through it last year
it`s now my back up and is still able to run the 19-11
I just put bearings in and bagged it up LOL.
