I inherited this bike from a family member & not sure what kind of engine this is?
Any help is appreciated...

 

That's a Power Plus 100" motor, the last 2 years of the Indian chief had them before Polaris bought them this time around, some outfit in the south east somewhere was selling them for a while to, parts still around if you hunt a bit. Engine, trans controls and the electrics probably came from all the extras from the auction when the old factory in Gilroy sold everything off.

Thank you.

 

I worked for Indian when they had those engines , they are actually pretty strong and a smooth ride.

 

Yep, It's a second resurrection Indian bottle cap motor.. Current resurrection is 3.. It was designed by thunderheart. IIRC the outside interface is pretty much the same as an HD evo. I heard that early motors had oil issues and someone was making a fix. If you have issues you can replace with an evo motor..

 

That's cool

 

Thanks for the info, any idea what year this engine may be, 80's/ 90's or newer? Thinking about adding a temp gauge to keep close eye on engine temp. Cool to know I can replace the engine with evo, bottle cap look is awesome though.

 

IIRC they were made from about 2002 to about 2004.. Twisted will know for sure.

 

They made those from 2001 to 2005 for Indian if I remember right but they didn't come for retail till 02, original company that made then is still selling them I believe. I rode a few bikes with that motor, was very strong and smooth.

 

I will add replace anything electrical that's Thunderheart particularly the ignition, had loads of bad stuff from them.
