Remember, it has been
found that using ODD/ODD or EVEN/EVEN
combinations of front and rear sprocket will
cause your chain to wear faster than using an
ODD/EVEN combination. Oring chains are
wider etc than the old school non oring chains.
I have found it difficult to install a 16 tooth
front sprocket on early roundcases [sandcast
engines] using an
oring chain.
My favourite combination
is a 16/39 on my Darmah. However, I stock
both 15 and 16 tooth front sprockets as well as
36, 37, 38 and 39 tooth rear sprockets in order to
offer the widest combinations that are more
useful today. Remember, tall gearing was
installed to keep the revvs down to help pass
DOT noise restrictions etc... I prefer to
get a better jump off the line, this helps
around town riding etc as you never want to lug
the engine. |
