Rebel, thanks.
Orsum, that's a definite possibility. I am trying to bias a little more weight forward, but the fans shouldn't weigh much. I already have the auxiliary shocks to assist the rear springing - the piggyback units actually contain a couple of springs per side which adds up to the right stiffness to support the heavy back end. By the way this engine is running a simple muffler only and no large tuned pipe, unlike the 2-stroke which is a big plus as that was difficult to package in.
I guess I will run it without fans first and just monitor the temps. Need to machine up a throttle linkage first as currently there's no simple way to connect to the rotary carb. I can't have any servos anywhere near the engine. The vibration is way too much. If this drives as well as it idles it will be a wild ride, the idle is violent. Hard to believe it is a 90 quid engine, it is a real beast and the machining in it is unbelievable value for money.
