WHY I VOTED YES , Likewise I'm in the yes camp , back during my first connections with A10's from 1966 , I did nearly 19000 miles in 8 mths on a plunger ,first bike and hammered the hell out of her , she finally let fly coming down wheatley hill just outside Oxford , next up was a 56ish A10 ,with Ariel brakes rebuilt it using a plunger engine and just swapped everthing ing into the small jornal s/arm cases ,talk about ignorance being bliss , didn't know about the sludge trap and the importance of end float anyway I put her together being very careful and boy was it clean ,(apart from said sludge trap ) that engine proved unburstable ,I got really fed up not having to work on it ( stupid kids )and abused the motor as only a 17 yr old could and it was, also given that it had a 3 rd wheel , Board fitted no sidecar couldn't break it , in the end having got my dream job selling bikes and more importantly being given one each night to "test " it sat neglected by a friends garage until it was broken for spares .
So actually my experience should have seen me go down the standard route but when I rebuilt my present bike back about 13 yrs ago alas without the help of this fine forum and it's well informed members ,i remembered the "problems "with the plain bush ,could still recall a firm called Devimead and finally also it was going to be my last bike so I wanted longlevity and getting some sense at last ,coupled with min spannering so went for the SRM , they did big ends ,new drivesidebearing ,cleaned the sludge trap ,fitted the end feed conversion ,rebored the cylinder block and supplied 8.25 pistons ,a spitfire cam ,stelight followers and finally balanced the crank ,recut the valve seats,fitted new bigger inlet valves ,guides etc , the cost approx back then £1800 ,thats a guess ,I've put the receipts away but in my mind money well spent, I put it all together marvelled at the work they'd done and have enjoyed 10 yrs trouble free running , well almost . Hope that lot didn't bore to much, regards Bob
