Sorry I didn't see your post sooner.
Got a couple things for you.
I did the exact same foot control change with assemblies from a 2008 Monster. I got a custom brake line made by Spiegler (www.spieglerusa.com
) for $80 including shipping back in March of '16. I used a 90 degree fitting at the master cylinder so that the brake line comes down in front of the swingarm pivot then under to go into the brake line guide. And a 15 degree fitting at the caliper. You'll have to measure for the additional length which is about 5 inches longer than the original if my memory serves me.
I got a SpeedoDRD from 12oclocklabs.com to correct the 8% error built into the speedometer reading.
I also got a quick change rear sprocket setup from AFAM. As you already know, stock gearing was 15/39. I changed it to 15/43 and added 2 links to the chain length to keep the center distance between sprockets almost the same as original. Almost the same as just putting a 14 on the front. But, with a greater chain life because of the lower tensile forces being put into the chain due to the larger radius if the 15 vs the 14. Still good for 138 at the rev limiter in 6th, according to www.gearingcommander.com
, with big smile difference in acceleration. The only caution to this is the chain adjustment. The adjustment dimension on the swingarm sticker is no longer valid. With the larger radius of the 43t sprocket, that dimension is now 2-7/8 (73mm).
Hope some of this is helpful.
