Sorry mate been a bit tied up.
I presume you have a MK2, as I said there are a few threads in readers rides that will show you what others have done to there.
Two of our moderators
@Jimbobcook and
@Legojon have MK2 one is perfect stock condition and the other at stage 2+
At a rough guess I would say you need an anti lift kit (although I presume you have one already)
Upgraded FMIC
Upgraded engine mounts
The other guys should be able to
help a bit mre as mine is the MK3, You should also have a chat with apr to see what they recommend as coplimentary hardware to go with there stage 2 (The Revo site gives you this as well.
Put up a few pics and if you are up to it we always like a readers ride.
