Title: Ratio rockers ? Post by: Black Sheep on May 25, 2007, 09:13:38 am Hi guys .
How much clearance should i give my valve`s with ratio rockers , I'm running a 125 cam and I'm having starting problems . She will only turn over a few times before the battery gives in . When I hand crank the motor its bloody tight just before TDC and BDC , the cam is already bedding into the followers as these came from another motor . Ive gaped the valves as usual and I'm hoping this is nothing more serious . Any useful advice will be greatly received cheers fellas Title: Re: Ratio rockers ?

Post by: Black Sheep on May 25, 2007, 15:52:24 pm I think your onto something there , Im just off down the garage to pop my rockers off and check those springs , Im running single springs at the moment looks like the heads are coming off for a spot of duel spring machine work ! :-\
