So he's considering fitting 17/40 or 39 to reduce the revs & so vibes at say 70 or 80mph
Would this work?
the 18/44 is slightly slacker than the stock for the 650 twin. When I first installed this combo it was for a 3 day trip. 1,300KM with 800 of it on gravel, dirt and double track. on our second day which was more technical I was going to swap out the 18 for my 17 but couldn't get the 18 off. Thought it was going to be a crappy day as I remember the original stock ratio not being great for off road but it was just fine.
with the 18/44 it was pretty rare that I even had to get into 6th gear. I think it might be my favourite overall combo yet.
