Hi All

Sorry if this question has been asked, I know you will probably get fed up with repeat questions from noobs! (Ihave been searching for an hour for an answer)

Anyway I am about to start breaking in my UK Caster ZX1.5r RTR, it comes fitted with the RTR Go .25 engine, does this engine have the conventional short LSN or the GO long LSN.

It has the black coolling head, with silver block. I can get pictures if required.

Thanks to anyone who takes the time to answer.
