Pulling redline in top

[jotajohndude]

As my busted femur heals (slowly) I've been putting more miles on my 72 SF. She runs well but I do have a question for the forum !

Q The engine pulls the redline quite easily in top gear, and no there is not any clutch slip. Is this typical?
Q Can anyone help with what number of teeth the rear sprocket would have as standard?

Thanks

John

i don't see why it shouldn't pull redline in top gear 
sprockets should be 19 and 40

jotacorsa thanks for the info about the sprockets.

Hi John. Even my soft old GTL revs out in top, but I am running a 42t rear. Don't forget the red "line" is actually a band 1,000 rpm wide....she's just starting to sing when she gets to the end of it.

Guys thanks for the advice. I guess its been many years since i've owned a bike that i could max out in top. Just because she's nearly forty years ols does not mean she should be treated gently. I shall galdly and happily keep up the abuse

yeah - but make sure Oil is fresh always and has the right viscosity, valve-clearance is right, no airleaks etc. etc. ...
