Yup
Worth every penny!
Other than my Jett-50 it is the finest engine I have had in 17 years...
It is kinda like the Rossi's the 45 has the power of a 60- (if set up properly)
It is really meant to be run with a tuned pipe (Macs 7.5CC) but runs extremely well on a stock muffler- Put the tank anywhere you want, and have instant throttle response...Just use a good quality tank like Hayes (cuz the pressure..)
Do a search on here for YS-45.... and grab a snack!
