KR-1S.co.uk Forum

hi
can someone please enlighten me on the differences between a 1 and a 1S as i need a S engine

as i have to purchase one and have no idea on the differences

can you tell by the numbers or any physical differences on the outside?

also carbs - how to identify them and are they shared on any other bikes?

thanks for your help in advance

obvious noticeable physical differences are a screw cap gearbox filler on the 1 and the plastic thumb screw off cap on the 1-S.

The clutch inner casing is slightly different with an extra bolt on the 1-S. Harder to spot without taking the motor apart, but the barrels are different too. Numbers inside where the resonator chambers denote 1 from the 1-S.

thanks mate

gives me a guide

what about engine numbers

Maybe able to help. Replied to your wanted ad for carbs. Pm me

But you have to reciprocate and post plenty of photos....
