120r running on one cylinder at idle, too hot?
Noticed last night at a stop light bike was idling funny and my 5 friends had no idea and just made fun of it going ba ba ba ba ba ba. It would do that every ten seconds or so. One guy said it sounded like it was running on one cylinder. I have no oil cooler yet but do plan on getting one real soon. The temp was around 70 out so I didn't think the bike was running hot, anyone ever had this. It seemed to run fine once I got going.

Engine too hot?
Or did you put it to "parade mode" with "double-reverese-twist" of the throttle?

Richer mixture has a cooling affect. In Phase 3, if the ECM sees that the temperature is still going up, and the bike is sitting still, it will go ahead and skip-pulse the injectors, not delivering fuel on each intake stroke. Again limiting combustion and producing less heat. Phase 3 is only active when the bike is sitting still. These 3 Phases pass from one to another without pause, and you may not even feel or notice it.

It IS running hot. This is 'parade mode' and what it does is kill one cylinder to allow it to cool. I would NOT disable parade mode either as HEAT will do way more damage than any stuttering it will do.
Put a cooler on it. That really won't help much, but will maybe keep the oil viable when it gets that hot.
You can also get a parade fan. I like member Fabrikators (Wards products?)
The bottom line is the tune is NOT spot on. a 120r really needs a very decent tune to get em going right and have nice manners. This is not some 103 or 107, so ya know.
I wouldn't bother with a tune from a dealer, as it appears they did not tune it OK anyways. Where are you from? Maybe I could suggest a tuner within a days ride of you? It IS the tune. You seem to have a choice or two. I would call R&R Cycles and see what hey could do about your tune. Also, there is BigBoyz in ME. THAT tune would be an open loop tune, which isn't a bad thing on a big *** motor like a 120r anyways.

Is my 180 oil temp equivalent to the 300 degree temp or do I have a faulty engine idle management system.......or is this something completely different than the ECM program referenced in the quote below?
Thanks,
VR
