back in the day FOX and K&B with some Rossi (thrown in for good measure) glow plugs where the norm. Seems like everyone and there brother are making them now.
I use to run mainly K&B's with idle bars and have enough left over to use them up in my .65 sportsters

Question is:
whats the best choice for OS and Saito 4-cycles now a days?
Hanger 9 or OS type F maybe?



Gawd I feel like such a noob!
