If that a real world 70 its going well for a muggy 225 my v1 topped out at 60 which was very dissapointing I have had to take the dremmel to mine and with 30mm del, sx200 gearing , and taffy pipe it reaches about 73 . a new pipe may produce more power which may allow a higher top speed but if he rid...

you can dremel the inside of the rim have done this a couple of times .when I rebuilt my gp I screwed the top and bottom together and took it with me to a parts fair and went round the stalls till I found one that fitted , needless to say 12 mnths later the chrome was leaping off . I have 2 original...

if you file the slots you can retard it further

paul213

you could just retard the timing on the varitronic just rotate the stator clockwise a little at a time until the pinking stops . this will retard the timing throughout the rev range .
have you checked your compression ratio this could be too high
