over the past 48 hours i have begun tearing apart the engine of my recently purchased/ first ever/ world reknowned/ 1993 CBR 900.

yep my headcase is stuck on some rusty pins to the crankcase. any help? ive used hammers and a car jack, i think what i need is a miniature jack to be correctly placed right under the inch or so of over hanging lip on the head case.

would anyone know where a small 4" jack? or had a similar experience?

try some pb blaster, i wouldnt reccomend a hammer or a jack, dont wanna break it.
