bmccormick08 Posted August 12, 2015 Report Share Posted August 12, 2015 This is what it does. It won't rev, just backfire. This is using the dyna coil. Timing back at 0 stock cdi https://vimeo.com/136154621 Sent from my SM-N910V using Tapatalk Quote Link to comment Share on other sites More sharing options...
Deadbeat Posted August 12, 2015 Report Share Posted August 12, 2015 prolly reaching but it wouldnt hurt to set the timing plate to zero for now...are they HJR spec domes? Quote Link to comment Share on other sites More sharing options...
bmccormick08 Posted August 12, 2015 Report Share Posted August 12, 2015 I tried setting it back to 0, no change. The domes were cut by Kevin for pump gas. Sent from my SM-N910V using Tapatalk Quote Link to comment Share on other sites More sharing options...

bmccormick08 Posted August 12, 2015 Report Share Posted August 12, 2015 That's what I don't get. My ignition was all stock before the engine build. It is still all stock. I bought the dyna coil but chose to start it on the oem coil since I new it was good and worked fine. But the factory coil is failing me now and the dyna starts it first kick. So I have to assume the coil is good. I need to get home and start checking resistances Sent from my SM-N910V using Tapatalk Quote Link to comment Share on other sites More sharing options...
trickedcarbine Posted August 12, 2015 Report Share Posted August 12, 2015 Stator/flywheel combo ain't charging up to par. Shake the flywheel and if it doesn't rattle I'd change the stator. Quote Link to comment Share on other sites More sharing options...
bmccormick08 Posted August 12, 2015 Report Share Posted August 12, 2015 No rattle sir. And I've already lightly sanded the inner drum and the pickup points. Which did not help. I think it's the stator as well Sent from my SM-N910V using Tapatalk Quote Link to comment Share on other sites More sharing options...
salmon_slayer06 Posted August 23, 2015 Report Share Posted August 23, 2015 Its possible the wire harness is grounding out on the frame somewhere, or you have a bad connection somewhere in the harness. I would also look at getting another CDI to try. I had spark when I had an electrical issue last time, and it ran...... but idled horribly and would stall out when given throttle. Bad CDI and my coil used at the time went bad. I had another coil already but the new CDI was the fix. I'm not sure why it went bad or why the coil went bad....... I think my harness was shorting out on the frame and wreaked havoc on the electrical. I recently pulled the harness off and found a spot where it looked like it may have been arcing to the frame. I'm still looking into it as I'm in the process of putting a 421 in. Quote Link to comment Share on other sites More sharing options...
Strm Trpr Posted August 23, 2015 Report Share Posted August 23, 2015 Also, showing 130 psi per cylinder on fresh bore and rings so compression is good, didn't hold pressure on leak down but it did pass the less than 1 psi per minute test. I sprayed the whole engine down case halves and all and couldn't find it. I think it might have been my tester itself leaking.Whoa, WTF?Let me get this straight, your motor can't hold 6psi for 6 minutes and you're trying to tell us you swear you've read that 1psi/minute is acceptable. I have no idea if that's true. All I know is a leakdown test must hold 6psi for 6 min. If it doesn't I'm tracking that leak down and fixing it. You just dumped $$$$ into your toilet if you don't find and fix your motor's leak. All I know is I go on a couple riding trips a year that are 6hr drives away and my junk better run perfect.

bmccormick08 Posted August 23, 2015 Report Share Posted August 23, 2015 That's just what I found, on here. I really think my tester is the issue. The gauge does eventually fall to 0 but when I depress the Schrader valve I get a fair amount of air out of it. As far as my bike running, it was a broken ground wire on the cdi. Once found and fixed it fired up on the first kick. Sent from my SM-N910V using Tapatalk Quote Link to comment Share on other sites More sharing options...

So you just spent ~ 600 bucks with Kevin and you're going to assume your gauge is faulty? Please when you burn a hole through your piston after a few short hours don't get back on here saying I just don't know what went wrong I did everything right please help... Cause when that happens you asked for it Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...
