Just wanted to say that after the top tank on my radiator blew up on the highway today I have learned more invaluable lessons, ie my natural instincts once again failed to correctly modify my Toyota, and my homemade radiator overflow pressureised my whole system and now I've got something to do this weekend! At least this swap will be easier as after the last three engines, all since February, I am getting much quicker at an enging swap. At least I still made it to work! On the up side, I have located a nice 4k with some secret squirrell work, and that will be another timeslip tune up Saturday night if possible. As a tip, and belive me I have tested this more than some at least, try not to get the poor little k too hot or the head/headgasget will not be happy. Still building the Freakmotor with the Norton Commando pistons, but I just don't want to rush it. Also, plug up your fire wall if you ditch your heater, cos that hole looks tiny unitl all of that hot, bright red {Rusty} boiling steam comes gushing in. Good thing no passenger in the front, or they'd be a little tener/juicy right now. Can't really offer any helpful advice/info but I'm still lovin' my little spoonfool........

Still building the Freakmotor with the Norton Commando pistons,

?? Hummm interesting.... Why them ??

 

Have heard of being able to use pistons from a bike. But what makes them better then the k pistons ?
