RR cam compatible question 2016 xr

[AdzventureXR]

Hi gents,
Question regarding swapping cams and engine upgrades.
Does anyone know anyone that has successfully made changes and what cams, followers where used. Brentuning has said they have tunes from previous customers, but not much input on the hardware. Any feedback would appreciated

There's a Gent in UK Called Jason, has made his XR into RR spec engine with RR cams, airbox mod, full Akra, ecu work by Phil Crowe, 195 rwbhp. Also upgraded brakes with Brembo M/C and Stylema calipers

Hi.
I'm about to do the same. RR cams and tuning from Brentuning. Akra headers, RR cams, IAT relocation, velocity stacks, Sprint air filter.
And stock silencer. I'm building a sleeper. Aiming for 190+ whp.
I have a 2019 HP
Hope that we can share experiences

Which brentuning are you planning to go too? In Korea there are not any reliable sources, so it adds more difficulty to getting resources and know how.

Thanks for your feedback, never been much of a Facebook fan, guess it's time. Lol

You will really want the springs and valves as well. The RR cams are more aggressive and really need the stronger springs to keep the valves under control and I would not use the RR springs on the standard non titanium valves.

You might get away with it on a road bike that does not see a lot of sustained high revs, but not something I would risk. I am going to change valves and sprints too. I just need to find them at a sensible price :-)

May be better to change the complete head to RR.

Yeah it could be, though you would probably want to check valve sealing etc on a second hand one. Also need to remember you shouldn't lap in titanium valves. If you need to lap the seats you need to do it with a sacrificial valve that you are not going to use.

If a ti valve has any damage or is pitted etc its scrap. So might be better to be able to see them and inspect them.

Would rr valve be compatible with XR head? I'm not clear at this stage. This is one of my concerns. My biggest problem is logistics and talent. Korea is not strong for tuners and rebuild. I may end up going with a new head. So need to understand what year RR is compatible.

Hi Bazzer
what is your experience on this topic?

I know that I need to change intake springs also, but I'm a bit reluctant to change the valves to titanium. In that case its much better to swap the complete head, which was not part of the idea.
As you mention, the bike will not live among 13k rpm a lot, as maybe a RR would.
I want to build a sleeper.

I have a brentuning today, and I don't go to a shop to have the work done, neither the ecu coding nor the hard ware. I bought the hand held piece and I've spoken to them about this, and if I can do a dyno run with A/F ratio they can adjust the software accordingly

I have a question too, do I need to remove the engine to swap the cams? Or is it possible to swap them with engine in place ?
I also want to mention, that my bike has only 8700km on the ODO, so I'm not worried about any ware on the valves or so.
