Top chain guide (pull down) adjustable, Series 1,3, Casa Performance
Chain tensioner from Casa Performance, tested by the Casa Lambretta Racing Team.
On a galvanized steel plate sits a self lubricating nylon block. The chain tensioner is intended for tensioning the upper chain guide.
Please note that with this part, you do NOT need to fit a lower chain guide!
Works with all sprocket/wheel combinations. With this chain tensioner all sprocket combinations and chains with 80 to 83 links can be used. It allows the chain to be tensioned up and down as needed.

As with all chain guides that use bolts, we recommend routine periodical maintenance to check the allen screws that hold the plastic runner are secure, although they have internal tubular spacers inserted into the 3 holes where the allen screws pass through. The presence of these tubes mean that the plastic runner cannot 'compress' and subsequently it is nigh-on impossible for the allen screws to loosen if this maintenance is adhered to. ALWAYS use Loctite to fix the mounting screws when fitting to the engine casing.
