Someone suggest I look into the S&S IST Ingnition, I really think this would be a great addition to my 120R build.

 

I am crawling out of my skin excited... I am pretty sure I am going this route instead of buying a new CVO Road Glide.

 

This is the response from Mikuni...


Hello Bill, I would lean towards the 45mm carb. On that size motor the 42mm would be to small, and the 48mm is more of a race carb, and little tougher to mount up.. The 45mm would bolt up and run really well, give you really good performance and throttle response. It will use stock Harley throttle cables, 92 and later, but it will need a screaming eagle CV44 intake manifold to mount up to that motor. The 45-5 kit. The kit comes with the 45mm carb and an air box adapter ring that will work with any aftermarket air filter that will fit the stock CV carb. It is a pretty universal kit.. You can check out our product at www.mikunipower.com We also have the instruction manuals posted and the tuning guide for the HSR carbs posted there. That would give you an idea of what would be involved with mounting up the carb.. let me know if you have any other questions.
