heres a few 120R **** pics.

 

Stroker - what's the little indentation at 'the 5 o'clock position' on the exhaust port ...?

THX for posting the pics ...!

 

If I was guessing, I'd say that is where the ACR vents when starting the engine.

 

....... oh my word, they're naked !! .... ............. and don't they look nice ?

 

I was just reading about this in my latest HOG magazine and sounds like you got a deal as the MSRP is $5495.00. The article reccomends the SE 58 mm throttle body and a Heavy Breather. Reading the article and the disclaimer that it is not intended for street use had me thinking your average Joe could not buy this engine but had me scratching my head as S&S makes bigger motors. Man, 135 HP more than doubles that of the 96!!!!

 

I think you'll find they're wearing see-thru bras!

 

I think they will be in the combustion chambers. More likely they're sniffers or sensors for the emissions/EFi gubbins (sorry about that engineering expression!).

 

If I'm not mistaken, the red circle identifies the compression releases in the head ....

I thought it rather unlikely they would vent to the exhaust port ....

Since the oxygen sensors have always been in the head pipes (or more recently in the collector), didn't suppose they would be O2 sensors ... but, suppose anything's possible ....

 

I will let Jim answer but for sure they are not 02 sensor mounting pts any where on the motor (race only right!) I am almost positive the ACR vent to the exh port. These little motors are about to get more naked when the cams get slipped in and some "other" stuff

 

Kewl!

I'm keeping tabs on all these 120r threads cause I'm thinking of getting one in Feb or March.....
