  Oct 19, 2012 - Valve Adjustment; you can check the clearances make sure that they are at the right amount. Always good to check this.

Full parts list just because I found it.

You don't 'tighten them down', you adjust the valve lifters for clearance. :>)

Hello friends i need v270 suzuki service manual. Pls help me. Thanks

Valve clearance ideal setting is 0.10mm however as ideal replacement size shims are not always available use tolerance 0.05 to 0.2mm inlet and exhaust Procedure remove tappet cover rotate motor to tdc compression (inlet valve lobe pointing to rear wheel and exaust lobe to front wheel) measure clearance if no clearance depress cam bucket hold down by wedging a screwdriver or suitable tool (allen key) between cam bucket and cam remove shim measure with micrometer an relace with a shim 0.15 thinner depress valve remove wedge and measure clearance (if any) repeat procedure 4 each cylinder if clearance to large replace shim with a thicker one till clearance is in spec
