GSXR 400 engine - Question on parts/specs

[m1tch]

Hi all,

I am going to be using a GSXR400 engine for a project, I have been informed that its an import engine and it runs on carbs. I am unsure on the exact year it was made although doing a quick wiki search they all seem to be about the same apart from the very late model which seems to have a 7bhp drop (guessing emissions stuff).

Anyway, I was just wondering about parts for the engine, are there any parts in common with other bikes that could be swapped over? Anyone have any opnions on the engine at all? It seems to make around 60bhp and rev to 12k rpm so not too bad for a small engine. Does anyone have any technical specs on the engine eg compression ratio, valve lift etc?

Thanks in advance

I have a full running engine you can have with all ancillaries for 150 no restrictions in it either

I already have the engine, how can I tell which year it was from?

So is the 73 the most similar to the Bandit then?

OP, fancy flogging me your cams?

Engine is decent, make same power as the GK73, however, it is near impossible to tune extra power, due to the fact that jetting cannot be changed since there are no other jets available on the market for the carbs.
