RM-Z250 2012 Suzuki RM-Z 250 top end help

Sorry for the long response i have been extremely busy but i have some news! This was my first with dual cams so I got the exhaust cam off by one tooth!! I fixed that and it fired right up and sounds great, just i only ran it for about 10 seconds till i get coolant for it and the header was already extremely extremely hot even with it being 26 degrees out it feels like its already up to 90+ in 10 seconds. I do have the titanium exhaust for it so it is a little bit thinner just i dont think it should be that hot already should it?
 
The exhaust gases are anywhere from 600-1000°f so, 100°+ in 10 seconds seems pretty normal to me.
Alright thank you, i just wasnt expecting it to get that hot that quick. This is the first time with a basically performance engine and a titanium exhaust so I didn’t know if that was normal or not so thank you so much!
