Then they could not get it anymore because of increased use of this long straight road known as Tram Road, North Canterbury, NZ. I will try and give you a rough specification of the past and present of engine and cycle. I have and still hold some records in the 37 ci class, under 750 cc class, 55ci class and lastly 61ci class, all with my 1920 flathead Scout. My first major record was the NZ Open Road record established on the Aylesbury straight in 1940 at a mean 120.8m.p.h. This was held for twelve years. The under 750 cc Road record at 143.43 and NZ Open Road record at the same time. Also NZ Beach record in 1957. Although this is still attempted each year it remains unbroken at 132.38 m.p.h.
55 ci AMA world record 1962 at Bonneville, engine was 51ci at this time. 1966 engine 56ci 168.06m.p.h. American 61 ci record 1967 183.6. best run 190.07 qualifying. 1969 record number of runs for a streamliner, 14 in four and a half days. I had magneto and carburetion troubles and finally burned-up pistons when gas tap shut off on last chance of a qualifying run. I have hauled bike or engine to USA eight times in my attempt to get one good run but this has always eluded my greatest efforts.
The last 22 years has been full-time as I could never get enough hours to do things. After finally getting 94 m.p.h. from the flatheads and running on Borneo Aviation Gas I ahd a go at making ohv heads. A foundry told me how to go about making patterns and I finally had them finished after a year of work until the first day it ran. Believe it or not the first runs were slower than my best on the sidevalve but over the years I gradually got it going faster till in 1937 I was getting 110 m.p.h. from it, also breaking conrods. About then a mate and I were returning from a distant beach meeting and another pair of rods had broken, and he said why not write to the Indian factory and get special rods. This got me thinking and I acquired a broken Ford truck axle and carved out two rods in five months. These were in it for 20 years and were standing up to over 140 m.p.h. By 1950 I was getting 150 m.p.h unstreamlined.
I have had many terrific blow-ups, the last two were during this last 11 months. I will describe one I had at Muriwai Beach, Auckland in April 1969. I hauled my Munro Special up there 1130 miles and blew a piston ( I had just made thirteen new ones for 1969), the rod and pin toe up and down, put tram tracks and split both new cylinders, punched large hole in front of case, bent mag armature, broke slip ring and magnets on ML into five pieces. I hauled home and in eight and a half weeks had it running again. Eight more new pistons, two new home made rods, magnets cut form an old Bosch magneto.
