that 30 will mount in.
1st- remove the through bolt and the spacer between the motor mounts and replace with two short bolt , one for each mount . that will free up the space between the motor mounts.
2nd- you will need a 30mm intake. Remove the plastic spacer under the stock intake. Mount the 30mm intake directly to the head with a gasket.
3rd replace the stock rubber connector between the carb and intake with a another rubber section of hose that is 3/8" longer. you can use the original band clamps.
The 30mm will slide in but will have to mount tilted slightly to the right so the bowl clears the passenger side motor mount. This tilt has no effect on operation or performance.
you will most likely have to re route the throttle cable over the top to reach the carb.
Order a range of pilot and main jets. Every change you make to that motor will effect jetting. like a different exhaust for example
Keihin main jets- part #99101-393
pilot jets #N424-21
A range of mains 138 through 145 and pilots 35 through 40. A combination of these should get you right.
To give you an perspective, a motor with a 30mm intake , a large valve p&p head and a 1" Id performance exhaust took a 38 pilot and a 145 main.
on a basic stock motor the biggest gain will be the instant throttle response due to the accelerator pump. but as you upgrade the head and exhaust you'll feel more advantages.
