No factory BH will contain a clutch explosion.Having said that,scattershields are a pain-in-the-ass.
Lakewoods suck.Mcleod is a better unit.Both hang too low and you'll have ground clearance issues.
My McLeod Street-twin aluminum fly wheel & clutch set-up are rated to 14,000 rpm.I feel safe with a factory bellhousing as the motor can not rev past 6500.
