Hi Guys
Thanks for all you help in previous topics
This next call for help is doing my head in
I 'm running an 18" wheel and speedo drive from an old 'G' Reg Suzuki GSXR750 with 120 90 18 rubber.....& wait for it..... A speedo from a 535 virago cos its chrome and looks good.
The overall diameter of the 120 90 18 tyre is 674mm
The overall diameter of the Virago tyre which was a 19" was 641mm
A difference of 33mm about 1 1/4 "
Any ideas if this will make the speedo faster or slower, & if it is greatly inaccurate how can it be rectified
Please help...I'm pulling my hair out
