I also have the same problem after the 116 install, my dealer sold me a new starter trying to fix it with no luck, I tried a different battery with no luck also, on a really hot say it acts up the worst, I've been living with it because I understand why it's happening just like you due to too high ratio. Put the stock tune back in and same issue also. Runs great other than that.
My dealers kind of play stupid with me and honestly your the only guy who said it like it was.
I told myself I would never post a long winded rant they never solve anything. But seeing Riviera's post, I thought I would tell the rest of the story....
...After almost two years working thru the dealer, I opened a case directly with Indian about three months ago, trying to get some resolution before my two year warranty runs out. I gave them a pass for over two months because the case rep said they were run over with all the Challenger issues on the heals of the FTR issues (which I also experienced). I am patient (although I would hate to see the total time my bike has spent in the shop), so I waited, about month ago I get an email that Indian wanted me to provide survey input on my resolved case. What resolved case? WTF!!!!! Who, what, where, when, how was it resolved, no contact with me, bike has had nothing done to it in 6 months.
Called the dealer, in their files is a note from Indian to tell the customer that the bike operates normally, 116s are hard to start when cold and the kickback is acceptable starter backlash, and run 15w60 oil. Really.... I went home and immediately recorded a video of the bike starting and kicking back several times on cold start, temp was 45f outside and sent it to the dealer asking them to get my case reopened...
Fast forward to earlier this week, dealer told me Indian has a "new" ECM tune for my bike that will fix the problem (I believe it is 116 mechanical issues not a tune issue, the 111 prior to 116 ran great for 400 miles). They loaded it and it started normally at the dealers shop, so Indian is claiming success. The problem, it is 60F-70F in their shop and I normally experience most of the start problems with 50F and below. So, yesterday morning around 5am, I go to my shop, which was 52F (not as cold as I would like for testing), and guess what, it kicks back once and on the second attempt sputters to life. I would say it is not fixed... but I am sure Indian would say that is normal. Now that warm weather is approaching with lows in the 50s, I will likely have to wait till next winter to make my case again.
BTW- My warranty expired 3/10/20...
I wish I had never bought the 116 kit, it has caused more problems than any benefit I thought it provided. I have owned 4 Indian bikes over the past 3 years and was trying to make a deal on a 5th bike this month as this saga was playing out, not sure with the Scout, 116 and FTR issues I have experienced and now the Challenger issues out there that I need another Indian to fight... I have been a loyal supporter (a bit of a fan boy) of Indian (even owned a Victory prior to Indian), very active IMRG member (held all the officer positions in my local chapter), supported national rides, etc. All I want is for Indian to recognize there is an issue and either fix my bike to operate normally or make it right by mutually agreeably resolution. I guess I will keep wishing...
Sorry for the long winded rant... off my soapbox now.
