" Nortons were more oil-tight than Triumphs. "
Not sure that'd apply to MANXes , accey boy . now , whereas , a T100R . . .
Geared for 120 at 7000 , it'd pull 8000 in 3rd , close ratio box . on the straight , at the club ( short ) circuit . Pukekohe . On Avgass 7 1/4 : 1 C.R. ( Class ' C ' was 7.5 max )
Was Morrie ( Maurice ) Lowes engine .( Maybe in the Bonnie book , around P 50 . possable even Turner had a spin, back then. perhaps . Maurice certainly is )
Cut at 72 , back to 7000 at the grandstand , long track . Past by womble . Full T*t , a few surges and out to 7600 , then dice for the L H / Brakes , as the full Grand Prix circuit .
Sat down a few inches , pilot aboard . Prog. Rate Springs , F & R . p.s. Put your chin on the chin pad , BEFORE you hit the bump . NOT above it .

and dont poke your tounge out .
Butcherd ex pranged commando frame toobs & 68 Tri Swing Arm . 3 .00 - 19 KR 76 Fr. 4.25 - 18 R Rear . Rather Gummy . Whole thing groaned and shuddered drifting the R H at Bay Park at about 45 in 2 nd .
Was gunna do a fresh 1 1/4 mandrel bent frame . That Suzukis frame was same tube Dia. but runs were 1/2 as long again . Seen a few Jap Fours with horrible oil leaks .
Proceedure was lap surfaces , and use steam pipe gasket paper , plus maybe PLIOBOND otherwise , if they were parked indoors .
Pre 1960 EVERYTHING had its ANUAL DE - COKE , so servicability was of more importance , plus a bit of oil flung around on winter salted roads only did a bit of good .
Crikey , AIR CLEANERS were an OPTION in most countries ! .
So whats a little bit of external oil , anyway . Durability was the primary objective , and serviceablity . Most of them had to earn their keep . Should neverve got rid of all that gear .
7600s 130 , with more to come . Bout as fast as a short stoke Manx , due to lighter'n smaller . Celertion & sppeed maybe . If youre ' under the paint .
71 C'do Fr Guard tapped the steering damper , it'd come down level , F & r ' on the stops . Tip Toey with narrow rims , but , way over , you had a lot of tyre on the road .
So their fancey new lean angles are nothing new either .
