Hi Tim, do you ever remember seeing any racing twins that used the kickstart cover compartment as the breather catch tank. Only I've seen pictures up close of John Surtees Lightning, and this is how he has done his. Also do you know of any benefits or not, to running separate oil feed lines from the top of the timing cover to each cylinder head, verses the usual of running all the return oil via the heads and back to the tank. The reason I ask is because I am running a two start pump, and wondering if the extra oil could benefit in other useful ways, such as.....if the cam bushes and spindles are as new, why can you not do away with the oil restrictor in the timing chest, and just run full oil pressure to the whole lot....Surely if the cam/ spindle clearance is ok, then the crank will not starve of oil would it......Any thoughts much appreciated, cheers for now............Greg.
