What water/methanol kit are you using?
I have read here and other forums about turbocharging motorcycles, and the heat issues that occur. Several people have mentioned water injection kits, but I don't see much mentioned as far as model names, numbers and pics. If you are running water or methanol injection, please post up your kit name, manufacturer, pics, and nozzle sizes and settings. I have a 660cc turbo car engine, so the space and flow requirements of motorcycles are more applicable than 2+L car engines.
