o-no-moto Posted April 25, 2017 Report Share Posted April 25, 2017 Been trying to figured out this random misfire on the 06 Sprint 1050. Happens anytime the throttle is above 2500 rpm. No codes and have done a cylinder cut out but doesn't appear to have a bad coil or injectors. Replaced plugs and swapped in new coils still does not change anything. Talked to j.d hord and is backed up a ways and is not sure when he can get to it. The misfire isnt bad enough to drop a cylinder but does fluctuate 100-200 rpm and makes the bike have a jerky feeling while riding. Chain isnt sloppy and will do it while on the stand. Thinking possable fuel pressure' crank sensor? Quote Link to comment Share on other sites More sharing options...

cmh_sprint Posted April 26, 2017 Report Share Posted April 26, 2017 Have you posted the question/issue over on triumphrat.net? There are some pretty knowledgeable guys over there on the 1050 ST. Quote Link to comment Share on other sites More sharing options...
o-no-moto Posted April 28, 2017 Author Report Share Posted April 28, 2017 I have but dont really get any replies. Must not have the Euro swag or something. I did get a hold of j.d hord and am dropping the bike off with him Saturday. Quote Link to comment Share on other sites More sharing options...

Hope you get it sorted out so you can truly enjoy this wonderful motor. 1 Quote Link to comment Share on other sites More sharing options...

thompsonian Posted April 28, 2017 Report Share Posted April 28, 2017 IF I can locate it, I've got a Haynes manual for the ST1050 if you'd like it. Not doing me any good. 1 Quote Link to comment Share on other sites More sharing options...

Helmutt Posted April 28, 2017 Report Share Posted April 28, 2017 (edited) Like @oldschoolsdime92 and I mentioned, hoping it's a simple pump starvation issue ( filter ). Keep us posted on what Hord finds out with it on the dyno this weekend. Also, you're welcome to my factory service manual ( 2011 GT book, but I believe the engine's are unchanged from yours ) if it will help narrow down the issue, or if you need any specs/diagrams to chase down the gremlins Edited April 28, 2017 by Hellmutt Quote Link to comment Share on other sites More sharing options...

I had a 84 cutlass with a 3.8 i soupped up and my funds lead me to put a holly 650 on it. Yes yes i know way overkill for a 6 banger. I had to jet it way down to be able to drive it. If i ran a ( well say a 82 jet ) was a bit rich but then dropped it to a 80 it would have a lean spot in about the same rpm band and conditions as my sprint does now. But yes i will keep the post updated. Many times i follow a old post for a problem only to have no out come. Quote Link to comment Share on other sites More sharing options...
o-no-moto Posted April 29, 2017 Author Report Share Posted April 29, 2017 Well just got back from the tuner. First off j.d hord is a cool guy and will be getting all my bike business. Made a couple of hard dyno pulls while monitoring a/f ratio and everything looked good. Discussed what my concerns were and also showed him. We came to the conclusion that the tire 'chain.and sprockets need replaced. Also will be looking at the cush drive. Didnt want to thump to hard on it with the drive line slop. Yes the chain was adjusted before i took it but after a few hard pulls it slacked back up. So new parts are on ordered and we shall see 1 Quote Link to comment Share on other sites More sharing options...
o-no-moto Posted April 30, 2017 Author Report Share Posted April 30, 2017 And for what its worth. My bike made 115 hp not sure on the toqure as he didnt have his tach hooked up. He showed me a dyno pull of someone else's triumph like mine and it had 117 hp. Said the map that was in it was pretty good and he wouldn't really be able to improve much on it. He didnt decline to try and inprove on it but i figured the money would be better spent elsewhere. Quote Link to comment Share on other sites More sharing options...
vf1000ride Posted April 30, 2017 Report Share Posted April 30, 2017 (edited) That's not so bad, mine made 120 on his dyno a few years back but I had the aftermarket pipes and did the CAT and SAI delete. This was the best we could get from it after about 45 minutes of tuning. Edited April 30, 2017 by vf1000ride 1 Quote Link to comment Share on other sites More sharing options...

o-no-moto Posted May 8, 2017 Author Report Share Posted May 8, 2017 So finally was able to install the chain' sprockets and new angel gt tires. Bike glides like butter and the hurkey jerky miss is resolved. 2 Quote Link to comment Share on other sites More sharing options...
