Just recieved a casa 185 cylinder kit. I'll be fitting it to a gp150 engine with a scootopia 22mm carb running through a ram air and a no name clubman type exhaust. Made the mistake of ordering a 19tooth front sprocket so don't think I'll be changing from the standard box for the moment but wondering what jetting set up to use? Have a 150 and 200 slides and the different atomisers too. Hope someone can help get me started!

I run a similar setup on my GP. Not with a remote filter however. I use a 45 pilot, 5899.2 atomiser with a 123 jet and the standard 50 choke jet along with the 200 slide. Given that you're going to be drawing more air you'd probably want to go up to something like a 125 on the main I should think.
