$60 on 00 ex adjustment if i remember correctly

It's pretty easy though, just need to get
+manual
+hondabond hightemp sealant for cover gasket
+flat tip screw driver
+wrench (10mm??)
+feeler gauges
+timing gun
+harmonic balancer holder thingy (to retighten the crank shaft bolt) - needed only if someone loosen it b4
