Rad empty but coolant tank full ?

I wouldn't think that is necessarily a problem worthy of another 6 hour drive. With the way the motor was probably sitting in the corner of the work shop and then oriented in your car on the way home - I wouldn't say it's a faulty motor just yet. It has a warranty, right?

it does have a 28 day warranty so i have a whole month to blow it up.

well i looked into the ports today and it does seem to be the valve rocker gasket. It looks like the oil has pooled by the plugs and on the ones with oil you can see it past the crush washer and onto the top part outside of the chamber.
I think this is probably a good thing.
Unfortunately my compression tester doesnt have a 10mm thread so i haven't been able to complete the test but a local garage will do it on saturday for me.
Please forgive this potentially stupid question but could it still pass the compression test if the rocker gasket has failed?. Otherwise i am potentially not going to find out anything other than there is a problem.
thanks

So this is me throwing in the towel !
The engine passed compression test with 185 on all cylinders. hooray.
yesterday i went to remove the the valve cover and one of the bolts snapped on the corner (closest to cylinder one and level with the cylinder head). so a friend who is much more capable than me tried to drill out the snapped bolt, all going well until the drill bit snapped !. by the time we tried all manor of things to move forward the hole was just widening and is now too wide to tap and still has half a bolt in the shaft.
There is a machine shop who specialise in engines and can helicoil not far away. however if i need to remove the cylinder head will i need a new gasket ?. the reason i went with this engine over working on the old one was because the head gasket went and the cost of a new gasket etc.. made it not cost effective.
If the machine shop need the head removed my question is will I need a new gasket?.
i think i am going to take up riding push bikes !!!

/i have decided to pull the head, get it sorted by the machine shop and do the gasket as well. having now broken a bolt and screwed up the threads i cant really return the engine so have to push on with it.
i checked the valve clearances and all the exhaust ones we good but the intake ones were all less than .15mm and the optimum is 16 so i might as well do them as well. my gauge had a broken feeler so i cant tell if they are less than .13 but 6 out of the 8 were <15 so i will pick up a proper gauge and order some shims.
I really hope to see the end of this bad luck soon.
All this for a 1993 cbr, i must be crazy or have a bug
