Plus yo'll prbably need the cdi as it fires differently.
Don't know much about the 30 but doesn't it have 2 rads instead of a rad and an oil cooler ?
The carbs shouldn't be a problem ( nearly the same size) but the exhaust might be.

If it's a 21 it's got an hydrolic clutch. Still do able but at how much work !

I have an engine for you Viv,I texted Dan last night.Let me know if it's any good for you.

ok geoff, we're off to fetch this one tonight
thats a 5 hour round trip

see what dan wants to do, thought it was too good to be true lol

Our garage is a propper dead shed now what with my blown cbr400, the vfr400 and the zx7r dead too

I thought nc30 engines were supposed to be bombproof... what happened to yours??

I do have one if you're still interested. And since you have a knackered one you'd have no problems with replacing a cracked case :)
