Couple questions popped up. First, how much will it matter if the float valve is 1.7 instead of 1.0? The bought it for the float needle but when I installed the new 1.7 float valve too because, well, it's new and came with the needle. Also, gasket - insulator - gasket. The Clymers book is proving to be, as most have said, too broad covering too many models to make any sense. This is my inlet pipe. According to Clymers, that's for a CT90. Anyway, my question is about the insulator. Is that required? It wasn't being used and I think I found it in the parts box of the bike. I purchased a complete gasket set (Vesrah) and it comes with one gasket for the inlet pipe-to-head. I see individual gasket (Honda) parts for sale. Is it better to get the gaskets and use the insulator (heat stop)?
