This will contain many questions - all which i would love to hear personal experience and/or advice.
My 70cc Garelli ssxl with a 15mm bing and a 26 tooth rear sprocket was hitting a top of about 41 mph. and a slug off the line due to the 26 tooth. In reality I should be able to hit 40 MPH on this with a 32 rear sprocket no problem, which would fix my off the line issue.
I just put on a MLM sidebleed and was sad to see that I actually lost top end and gained little/no low end.
My thoughts - I need to go bigger on the carb and intake. I am considering putting on 19mm PHBG and a 19mm intake. However I know NOTHING about the jetting on a Dellorto. is it that bad? I've heard it's complicated.
Vs the Bing I have really grown to like the simplicity and know the jetting decently. along with have collected a rang of jets over time. I could do a 19mm Bing clone but don't know if an expensive $110 clone is a good idea.
PLUS it is already pretty uncommon to run a Bing on a Garelli.
Should I just bite the bullet and go for the 19mm Dellorto?
Will getting more air/gas into the engine make me see more performance out of that pipe?
