Cutaway, Indian Thunder Stroke Engine
« on: Tuesday, May 21, 2013. 05:42:07 PM. »
I scanned a color cut-away of the new 111 cubic inch Indian Thunder Stroke engine. Here is a link of interested in seeing the scan. I am not sure how to upload and drop images into this message body.

One thing I always loved about Sportster and K engines was the parallel pushrod tubes for each cylinder.  Polaris does the same with this one.   HH

Looks like a chain tensioner, no doubt. All those parts look plastic, it's the colorful graphics

IIRC, they're hydraulic tensioned and twenty minutes to change every 50K.  They're both outboard and the cam cover comes off without removing exhaust / floorboards / pushrods...

Do you think they took notice of someone else's mistakes ?

Very interesting thanks for posting.

Other than BT Harleys I don't know too many bikes that take 1/2 day to change a drive belt as well. Immitating HD got them nowhere in the past with the evo clone, so it was time for a different prospective. This fresh new take on things really put them ahead in my view in maintanance and reliability. Some actually want that. :hyst:
Just think, no crank issues, oil pressure high enough to make lifters work as intended, no pesky primary chain and 3 hole oil changes. Now, with reduced pricing I think we will seem more on the road then ever.

Well I don't want it!

How in the heck will I run ATF for my clutch, if the primary, transmission and motor share the same oil??    :potstir:

my question is are the cylinders cast iron lined?? indian refused to answer. You would think they would be considering what the bike will cost.

If Nikasil is done right, it gives a long wearing, repairable surface. The auto industry has done well with it, for the most part.

I would agree that it's hard to beat having a steel liner in the cylinder.   :up:

Looks like cushion springs in the clutch assembly! That's the way to do it.

BMW for one uses it in cars It's not the product, it's how it's applied.

Vega cylinders were not Nikasil, they were plain aluminum bore, simular to the cheapy Briggs and Stratton engine on your lawn mower years ago.

Snow mobiles have used Nikasil liners for decades with success. I have no issue with them.
I am an adult?? When did that happen, and how do I make it stop?!

While I consider the Chief a butt ugly motorcycle, I think Polaris did a fine job on the motor both in looks and overall design..

NiKaSil motor stuff: http://www.cross-riders.com/articles.asp?Article=28788&fid=40

I've flown aircraft and owned several other motors with that plating technique. Seems to be ok if treated right per the article.

Also owned a B-Ugly V Vision for a while. Very comfortable ride. That includes Goldwings and HD's. But their heavy, and support is poor. They put the whip radio antenna inside the front fairing surrounded by metal, and then use the adjacent metal for the antenna's groundplane. Bad design. Just another bump in the road overall.
