Hi and welcome to FixYa,
I have a 93 ZZR250. Before considering replacing the engine, perform a compression test. Compression lower than 125 would be a cause of concern and therefore the engine swap would really have to be pushed through. Otherwise, it might just need valve adjustment.
Please postback results of compression test.
Good luck and thank you for asking FixYa.

results were around 105 and 115. I have found a lot of engines to choose from, so now am just after the zzr manual and any tips for engine replacement or things I should check on the new engine before putting it in.
What questions should I ask about a used engine and what should I check out before putting it into my bike.
So far I am asking:
- What condition is the engine in?
- How many miles/kms are on the engine?
- Does it come with any warranty?
