[QUOTE="Big Sid, post: 39456, member: 2781"] My drag bike running on straight methanol , 12.5 pistons , 1& 3/8s inch GP2s , Big Port heads , 2inch inlet valves , Mk 2 cams , twin open 2inch pipes 37 inch long , double lash gears with the high low gear ratio . Did the quarter in the high 10s at 140 . Ran only worn rear street tires , no slick and breaking traction the entire quarter mile . Could be heard breaking free as it ran through the lights . Left a black stripe as far as the eye could see . Won 40 trophies . To be young again ! Wish I still had it . If frogs had wings . Amazing reliable , never broke anything in three years of weekend running . Only thing Failed , ate one cam lobe and its follower . That's it in spite of winding to 7,500 in the gears . Lovely motor . Replaced a few rear tires , changed pistons twice . Methanol ran so cool that the carbs and manifolds would frost over during a run , heads felt warm , barrels hotter , cases felt hot . Ran 50 wt Racing oil , and Hypoid in the transmission . Gears stayed like new . Used a VW inlet valve as a pressure plate pusher working against a BMW Ball race thrust bearing located in the reversed C26 cup . Ever seen photos of it ? Sid . [/QUOTE]
