Just tried out my 17. This is in concert with a 42 rear.
Also, I run a 140/80 which totally fills up the swingarm to 1/4 inch all the way
around the front horseshoe and sides. (No chain guards anyway.) Guides, yes,
At an indicated 62 mph the engine was lazy-ing along at 3700 rpms. That brought it
up to the mid 4's and up to 5k at interstate speeds of 70-85mph. With the power
delivery loss of the taller ratio, wind resistance takes over and top speed remains
the same in the mid 90's to 100 on a downhill straight in a wind tuck. lol
Trying different things as I have 15,16,17,42,43 all to play with and two tire sizes.
The file seems close to dead on accurate other than variables we bring to the table
such as a huge tire, the transmission gearing change in 2nd and 3rd with Gen 2, and
of course not dragging and cooking the clutch. I wouldn't want to use synthetic with
the tall ratios putting more force on the friction plates. Dunno if that'll come into play
with 40 hp or not.
