As mswyka said, change the crank seals...The oil pumps on these are stout and rarely go bad, but it's worth checking while you have the motor out doing the seals.
I believe the engagement RPM was 5200, but I'd need to check the manual to be sure. It should have J-ramps and a pink spring in the stock primary clutch.
Interceptors are too rare of a sled to disgrace with duct tape. There are OEM replicas available, they are a little pricey, but very worth it.
Ditch the stock carbs and put on a set of 38mm mikunis. I believe there are some starting point jetting specs on this forum somewhere.
Again, change those crank seals, if you skip this step you will regret it...
Welcome and good luck!
