Hi,

sorry for this newbie question, but how can I distinguish a KR1 engine from a KR1S engine from the outside, without looking at the engine number?

Charles

the clutch cover is a little bit different (one bolt less - or is this in the right hand side cover ? , and the oil filler thing is a bit different )

there is an extra boltt on the balancer shaft cover.

but I don't know which is what

well if thats the case i've checked my manual and
kr1 has 7 bolts on the clutch cover and 8 (4x6mm & 4x8mm) bolts on the ballance shaft cover

@ Col :

my mistake

I was shure I've wondered why there was a hole in the right hand side cover, and none in the clutch cover on one off my engines and thought it was a difference between the both.

but now I inspected it closer, and found out that the hole in the clutch cover is cut off (the one on top off the oil filler).

to be honest i never thought there a visible difference between a 1 and a 1s

KR1 man calling. There is also one extra bolt underneath on the balance shaft casing of the KR1-S.
