BSA A65 crank mods.

[notjustyet]

OK here I am, 50+ and looking to get back on 2 wheels after a long absence.  Question is "onto what?".  I'm very tempted to go for a pre 70's A65 beesa, but would like some impartial advice about the great crankshaft issue.  For non thrashing use is the drive side support adequate or must one sensibly go for an SRM type mod with ball and roller bearing conversion?  If I do, what effect could this have on the value [origionality] of say a Spitfire III or IV ?   The opinions I've had first-hand are polarised so I would like your views.  Take it as read that the motor will be rebuilt with "sensible mods" such as an upgraded oil pump and a belt drive/needle roller clutch throw out bearing.  

This a great site!!

OK then I am here 50 + and always been on 2 wheels saying to you welcome back. You are thinking of the A65 beeza I am a Triumph man but I have two friends who run A65s  with the SRM mod  they reckon it's well worth doing, but you must change the oil regularly.With regard to originality any mod that improves the breed should be encouraged and this one inside the motor is not seen by just looking at the bike. I say go ahead find your Spitfire,  do the sensible mods and enjoy being back on 2 wheels. Happy Christmas. Dave.
