They are an issue because they are over 30 years old. The crank seals seal the crank case where vacuum is present for proper operation of the vacuum fuel pump. Bad crank seals equal low or no vacuum which creates no fuel or not enough. The clutch puller is around 25 bucks on ebay / amazon. Make sure you get the correct puller for the clutch you have. The comet clutch takes a different puller than the stock Yamaha clutch.
Fan side you can use a harmonic balancer remover tool you can rent at autozone.
