Approximately 38-40 Nm @ 6,500 rpm (Speculative)
Carburetion:
Dual Dell'Orto PHB 30 carburators (Typical for SL model)
Fuel Capacity:
16-18 Liters (Approximate)
Oil Change Interval:
Recommended every 5,000 km (approx. 3,000 miles) or annually, whichever comes first.
Valve Clearance Check:
Recommended every 10,000 km (approx. 6,000 miles) due to the desmodromic valve system, which requires precise adjustment.
Desmo Service:
Desmodromic valve adjustment and camshaft chain inspection/tensioner check are critical maintenance items.
Engine Oil Type:
SAE 20W-50 motorcycle-specific mineral or semi-synthetic oil, conforming to API SG or higher and JASO MA specifications.

Fork Oil Type:
Typically SAE 10W or 15W fork oil (specific weight depends on Marzocchi fork model).
Desmodromic System Wear:
Wear in the desmodromic rockers and valve guides can lead to increased valve clearance and potential performance degradation. Requires meticulous adjustment.
Camshaft Chain Tensioner:
Automatic tensioners can wear or seize, leading to increased noise or potential chain jump. Manual adjustment or replacement with updated units may be necessary.
Electrical Gremlins:
As with many motorcycles of this era, wiring insulation can degrade, leading to intermittent electrical faults. Proper inspection and repair are important.
Carburetor Tuning:
Dell'Orto carburetors require precise tuning and can be sensitive to altitude and temperature changes. Regular cleaning and adjustment are often needed.
