Hi all!

I've been looking at getting a bit more power out of my 2006 XT660R. I already have DNA and K&N filters, a PC III and an OTR 2-1 Titanium exhaust. I am interested in the OTR racing camshaft and cylinder head modification:

I read a post that reported a positive result from the camshaft. The cylinder head mod is supposed to give more power as well, but I am also interested in it because 'the thermal behavior of the engine will change in a positive way'. Having been stuck in traffic jams in the Middle East, there are many times I wished for better 'thermal behavior' (i.e. not having to stand with my legs wide apart to avoid my skin melting...). I know a large amount of my heat issue is because of the OTR 2-1 exhaust running right by my leg and have a small heat shield on it that helps a bit, but any cooler is always good...

Does anybody have experience with the OTR cylinder head mod? And any advice on how a racing camshaft and the cylinder head mod may affect reliability? Apart from having some fun around Holland I also use my XT for long road trips, and so far the engine has been faultless no matter what crappy gasoline I fed it. I understand that any mod is always a bit of extra risk, which is acceptable, but I don't want to end up in the middle of nowhere with an exploded engine just because I could get there faster...

Also, any recommendations for similar parts from other manufacturers? Or perhaps I am looking at the wrong thing all together, and other mods would be more cost effective/reliable?

Greetz from Amsterdam! :-)
