oppsie . should check the Captions ! .
Tiss actually a XR1000 I am thinking of .Thus.
1985 dunger , couldnt give em away . They all dropped valves .
Had ' stretch ' in Melbourne try'n say ' Sombody in America ' had rung & offered $5000 for a pair . After ' We ' had checked the Casting Numbers .
Had a valve head through the seat & a few dings in the chamber , when it ' Fell Off ' . ( the head fell off the stem ) . Had hoped to get the pair
for 300 , If they wernt knackered . :lol: :wink: mightve gone to 500 .
My humble theory being as the racers ( XR 750s ) are howling along at 7.000 rpms , the Oiling may need reviseing . Unless you tend to ride rather quickly .
One might consider guide / stem clearances & Cyl Head oil feed / flow rates .
But , they seem to go for a few bob these days . Getting one that hadnt chewed itself up , or a pair of heads , would be a good start , anyway . You could
pretend to be Evil Kninevel then.If you didnt have a Triumph 650 trackmaster .
