Hi chaps,I'm after some technical info regarding plumbing and running temps on a Malossi 225 running a Worb 5 l/c head .The scoot went to Germany and was fitted with a 4" square oil cooler type rad with fan mounted inside the l/hand side panel with vents,it has a VW 12v pump and the sensor is in the head.When my mate fetched the scoot back he was shown it running on the dyno with a big fan blowing through it but once back home he says it runs hot after 7-8 miles and he was told never to go over 95C or the head will warp. I had a look this afternoon and it all looks good but I wondered what would be the best way of connecting the pipes as regards flow?. I also noticed there is no thermostat or restrictor fitted in the system which I believe is needed to maintain pressure within the system so forcing water into all the head which I'm not sure has any galleries or is hollow.So basically what I need is someone with experience to guide me as to the routing ,running temps and which thermostat etc to use although personally I think the rad is no good but would like to try and keep as it is so well fitted.Thanks
As it is connected now the water enters the head at the top,and the lower hose goes to the pump then to the rad.I think it should enter the head at the bottom with the hot water leaving by the top but am not sure which hose to connect to the pump and where to fit a thermostat?
