Yamaha Chappy LB50 upgrade

Thomas Whittington /

I am restoring “2” Chappys and have several questions and would love all advice! First and foremost, I am going to order the Polini 19mm PHBG intake, Dellerto 19mm PHBG clamp style carburetor, Dellerto PHB6 carburetor idle jets, and Dellerto 5mm Main jets(qty.5)

1)Agree or disagree with this setup?

2)For the price, best supplier?

3)I am somewhat mechanical, how is the install? Time? Complicated?

4)what range of main jets should I order?

a) 40s,50s,60s,70s,80s,90s,100s

b)I live in Southwest Michigan

5)if there is anybody in the area that I could talk to and bounce ideas off would be greatly appreciated.

Thank you all for going before me to acquire the knowledge I seek.

I am doing the same thing to my Chappy here in Kalamazoo. What was your final setup?

Lol, did you bump an old thread to ask YOURSELF what you ended up doing?

This is amazing.
