sj 413 top speed ! anybody !

[Timi]

Hi all

 Just woundering what the top speed of an sj 413 is as i can only get 50 out of it ! 60 if i'm going down hill with a following wind!!!!!

 Anybody any idea , i've changed the plugs and ht leads as they fell apart when i pulled them off but that hasn't made any differance.  


    cheers ian

Depends on a lot as everyone else says, I have seen 92mph in completely standard 413, and seen an estimated 105mph in a 416 obviously only estimated taking into account bigger tyre size.
Check compression, ignition timing 10 btdc, air filter, tyre pressures, wheel bearings, and don't foget to check vacumn advance retard is working and that there is no perished pipe work on it! Also check to make sure exhaust, is not dented restricting exhaust gases.
