The zip is not really big enough to accommodate a 250 4t engine with rads pipework etc. Let us know how you get on !
I always tape over areas not to be coated and or use something like a wood broom handle to keep crap out of splines etc.

Has it got a spark ? petrol ? side stand down ? kill switch ?
