Carb rebuild questions:

When I had my Yamaha TDM the diaphragm/slide assemblies were $135 each, turns out that a Suzuki DR650 had the exact same diaphragm and they were only $20. Look for a bike with a similar carb (the TDM had Mikuni BDST 38 downdrafts, the DR has a BST 40). It might take some hunting and it helps if you can look at the diaphragms side by side. Having a good relationship with a local dealer helps!

The Kaw dealer should carry all of the o-rings you need for your carbs. Don't be scared to go in and price the parts. Bike bandit wanted over a dollar each for the o-rings I needed, the dealer prices ranged from ten cents to fifty cents... I got everything I needed for less than $10, including the gaskets. I was too late in matching up the diaphrgams though! The Harbour Freight o-ring kits won't have everything you need.

That Vulcan 750 should make a good first bike. They are a little underpowered, low and docile. Good things when you're learning.
