125-200cc WR/CR cylinder the same?

I have a spare 09 WR144 barrel with head and power valves. Is it the same as my 11 CR150?

And while I'm asking, should I have it ported, or would it not be worth the effort and expense?

Nobody?

If they are the same, I'd like to send the spare out for porting and leave the stocker on the bike for now.

Same, I would go with a 165 big bore and Lectron carb rather than just a port job.

pretty sure they all the same from early-mid 2000s onwards or so-went from 7 port to 5 port I believe

Thanks

I just happen to have a WR165 for sale right now. If I don't get any action near my asking price, I might just pull the 165 off, return it back to a 144, drop the price, and put the 165 on my CR.
I also have a Lectron, but it's an older one, and I'm not sure yet what to do with it.

So has anybody had their 125/144 ported, and can report on the results?
