I still haven’t done it but a couple guys on here have.Looking to refresh my 2015 R1 and was wondering if there is any issue swapping over to the 2017 valve spring setup? I noticed they changed the part numbers for the 2017 head but 2015 r1 and 2016 r1s used the same part number so wondering if you had any issues. Any help is appreciated.Well well well.
As it turns out, the 2016 r1s cams were used in both the 2015 r1 and r1m. To my knowledge both those bikes have the 14200 rpm redline from the factory.
In addition more good news. The 2017 r1 and r1m use a new dual Valve Spring setup and the cost to purchase all the valve springs, retainers, and the rocker shaft are a fraction or the 2016 parts price. So unless I buy the 2016 valve springs used, I will be switching to the new Valve Spring setup.
That being said, this mod is looking to be relatively easy for me. Since the cams are identical, it should be as simple as just replacing the valve springs and turning up the redline. It was my initial understanding the cam was the limitation (like an fz1) but the cam is identical to the 2015 r1. This is very good news for those of us that want the proper redline.
I am under the impression that there is a difference in the rod weight but not strength. For that reason I plan on running at least the cp3 redline (13750) with just the Valve Spring swap as they have steel rods. Honestly 14100 is probably what I will aim for.
What do you guys think is possible with a dual Valve Spring setup?
My parts list was basically just the whole spring setup and rocker shafts.
I also believe I was able to determine there was a slight difference in the cams themselves.
But if you have a 2015 r1, the valve spring should be a direct swap.
