This head is all assembled and ready to fit with the valve gaps set but we reccomend you check the gaps after installation.

This works well with 47mm to 52mm diameter cylinders. Ideal for C90 conversions upgrading the existing head to include a bearing type camshaft for better performance, tuning and less drag.

Technical data:
Exhaust gap:    0.12mm
Inlet gap:          0.10mm
Head torque:     10ft/lbs

Recheck the head torque when the engine has cooled down from its first run.
Check gaps every 350-500 miles or every 5-7 hours of use.
