v-rodcpa Posted August 24, 2016 Share Posted August 24, 2016 They've bumped the CID to 107". They showed the primary of a Screamin' Eagle with 114". The cubic inch war is alive and well. 1 Quote Link to comment Share on other sites More sharing options...

Tgwazu Posted August 24, 2016 Share Posted August 24, 2016 There's the four valves per cylinder Ken mention in another thread. $15 million in EPA fines?! Formerly plagued with recalls affecting "hundreds of thousands of bikes." ...and no drivetrain improvements... Me ridum RM 1 Quote Link to comment Share on other sites More sharing options...
BLUCHIEF Posted August 25, 2016 Author Share Posted August 25, 2016 Yawnnnnn Back to single cam 4 valve shower heads & no major drivetrain changes. The EPA SPANkings finally got results. goodbye Twinky So this has been done before ? I know 4 valve technology is not new but I've never seen it in a Vtwin. I think if someone is on the fence between an Indian and a HD, this engine might push them to the HD. I like the competition between the rivals to push the technology. I like motorcycles and what's not to like about what HD is doing ? I can only hope that Indian has something better in the works. My Chieftain has been in the shop now for almost 3 weeks with clutch and transmission problems so I am looking for a second bike. I can't afford another new Indian or HD, but I'm thinking about another 2000 Chief, has a great S&S evo motor. Quote Link to comment Share on other sites More sharing options...
CHIEF DOC 99 Posted August 25, 2016 Share Posted August 25, 2016 Jim Feuling had 4 valve head V twin patents back in the early days of the EVOs. He tried to pitch the design to Harley in the late 80s. Quantum Motorcycles out of Florida had 4 valve Evo engines in all their bikes from 1998 to 2002. The early 4 valve V Twins Indian had in the 19teens were factory racers Harley had some as well. 4 valves will move the mix thru the chamber quicker and does work well. The Milwaukee 8s are an improvement over the Twin Cam design. There may be some kinks to work out as the internal balancer seems odd, maybe prone to wear problems like the Twin Cam 'B' engines had going on.

v-rodcpa Posted August 25, 2016 Share Posted August 25, 2016 I had a Screamin' Eagle Fuel tuner as part of the stage 1 installed by my dealer in June of this year. No more of these from the dealership. That's what the Harley fines are about. They'll get the after-market suppliers next. These federal job-killing, no-account bureaucracies need to back off. Buncha assholes. I feel better now. 2 Quote Link to comment Share on other sites More sharing options...
BLUCHIEF Posted August 25, 2016 Author Share Posted August 25, 2016 Thanks CD99 It looks like HD is just trying to make a big deal out something that was already produced. I was looking at the Victory Freedom motor and I didn't realize it has 4 valves per cylinder. So I wonder even more what Indian will be doing next.

I was looking at the Victory Freedom motor and I didn't realize it has 4 valves per cylinder. So I wonder even more what Indian will be doing next. Makes me wonder if they started the design of the new motor when the victory 106 came out. Seeing as the new HD motor is a 107 ..

Brock Posted August 26, 2016 Share Posted August 26, 2016 (edited) Indian ran a 8 valve motor in 1913 and were in height of racing....albeit the technology was different back then....HD is not the first. https://www.pinterest.com/pin/1196337371169947/ https://eatsleepride.com/c/8877/1913_indian_8-valve_board_track_racer http://www.bonhams.com/auctions/16078/lot/156/ http://www.georgiamotorcyclehistory.com/thearchive/2016/3/15/pa7w8on9h08unqksesv6dueplrrd68 Edited August 26, 2016 by Brock 1 Quote Link to comment Share on other sites More sharing options...

v-rodcpa Posted August 29, 2016 Share Posted August 29, 2016 True. Sales are still brisk for the Colt model 1911 .45. And it's still being copied. Quote Link to comment Share on other sites More sharing options...

CHIEF DOC 99 Posted August 30, 2016 Share Posted August 30, 2016 The all new ChuckleHead Engine... Why a *chain-driven* single cam engine? Why not make it gear driven single cam like the Evo? Quote Link to comment Share on other sites More sharing options...

KenB Posted August 30, 2016 Share Posted August 30, 2016 I wonder why they went with the single camshaft.. a step back to their 1936 technology? I know a couple of guys that still ride EVO's, and both have had pushrod alignment issues = bent pushrods. You'd think they would have started with a lower end design like the Sporty has... Ah well - I got no skin in that game, so it don't matter. 1 Quote Link to comment Share on other sites More sharing options...

Bubblehead seems to be catching on. I did like Cameltoe and Knothead. Quote Link to comment Share on other sites More sharing options...
