DVS1 Posted September 10, 2006 Report Share Posted September 10, 2006 Ok so I have a stock motor 01 with T5s, K&N pods, Dynojet kit, no lid. It was a friends bike since new. I bought it from his wife a little over a year ago cuz he died. I have only ridden it at Glamis and Gordons well and its always been flawless. He used to let me ride it when he was alive 2-3 yrs ago. Jetting is correct for the dunes eventhough I don't know what size. Cant ask cuz he's dead and never needed to check. I recently put in a lightned flywheel, adjustable timing plate set to +4, billet impeller, and a Hinson clutch. I wouldn't normally do it, but I got invited to go ride up in the mountains at about 5000-6000 ft elevation. I didn't have time to rejet and figured it would just be pig rich and maybe at worst, foul out some plugs. The shee really ripped at first, but then when it seemed really wamed up it started bogging and detonating but really only on the left cylinder. I let it cool overnight, and the same thing. (Camping trip). I run straight pump gas VP 101 and Klots Super-techniplate at 40:1. I checked compression back here in Chandler,Az and have 128/125 left/right. I've always run this in the dunes with no issue. Question is why did it shit out after getting hot? It kicks ass for like 5-10 minutes then bogs and detonates. Could the gas just suck? It is pump "race" gas and I have no idea how often it gets cycled out and replenished new. Could the +4 advance cause or compound this? Is compression too low? It is a 5 year old top end. Sorry for the novel but details are important right? Any info would be appreciated... Quote Link to comment Share on other sites More sharing options...
Bansh-eman Posted September 10, 2006 Report Share Posted September 10, 2006 well with a compression of 120's your octane isnt the casue for it thats for sure.... my first guess is the advanced timing. are you sure its detonating and its just not the jetiing beingoff? how long has it been since it was ridin? jets might be clogged and need to be cleaned.

DVS1 Posted September 10, 2006 Author Report Share Posted September 10, 2006 I'm pretty sure it was detonating. Sounds like ball bearings in the cylinder. I got off it and limped it back to camp both times it started acting up. Last time I really rode it was at Gordons well for Easter, but it's been started and warmed up, first gear rip in the street then back to the garage probably 3-4 times since then. I completely went through the carbs before the Easter trip to the dunes. These were new plugs before the Easter dune trip. When I got back from Gordons well they were good, ie light chocolate milk. This is after two 15-20 minute rides. Quote Link to comment Share on other sites More sharing options...
Bansh-eman Posted September 11, 2006 Report Share Posted September 11, 2006 not sure man 101 with your compression shouldnt detonate. Quote Link to comment Share on other sites More sharing options...
dajogejr Posted September 11, 2006 Report Share Posted September 11, 2006 Bad gas or an air leak would be my guess... 130 or less and only +4 on the timing, you could run premium pump gas and it shouldn't detonate... Check all around the boots, etc... I'd bet your sucking air somehow... Just for giggles...what are you using at your timing reference?

DVS1 Posted September 11, 2006 Author Report Share Posted September 11, 2006 I do have a stupid boost bottle, but it started started to crack the stock intake boots last halloween so I replaced them with UPPs before the Easter trip (also when I cleaned carbs) and all was good. Also went over all that shit before I went riding this time too and seemed good. I'm using the seam where the case halves come together at the +4 mark. It's an Ebay adjustable plate, maybe its off and I'm more advanced than I think. ????? I'm going to put it at 0 deg and run it down here again to see, just need time. Work too much... Thanks for insights fellas. Quote Link to comment Share on other sites More sharing options...
dajogejr Posted September 11, 2006 Report Share Posted September 11, 2006 Hmm... If it's the ricky stator brand off Ebay, you should be dead on! Was the flywheel key perfectly straight when you put it back on? (Just want to make sure you don't have a degree key AND the timing plate)... You do have the correct mark for timing...I would set it back to 0 and see if it gets better...even though the gas you're running should more than handle it ...

dawarriorman Posted September 11, 2006 Report Share Posted September 11, 2006 Yeah, Id have to say everyone else is right. Its not detonation, you simply don't have enough compression /timing for it to happen. That is unless he already had a degree key, and then you put a timing plate on. First thing first though, jet it yourself. That way you know what you have, and you "know" its right. Personally I've never been a fan of the Dynojet kits. Not the highest tolerances, and since they use a different number scheme nobody can help you, or tell you what it is. That and I don't know if they would have a big enough jet for you. Im running T5s with no lid, and 340 mains. Even Toomey recomends to low of jets for most people. Quote Link to comment Share on other sites More sharing options...
DVS1 Posted September 23, 2006 Author Report Share Posted September 23, 2006 Check this out. I went to go back to 0 deg. and found the coil pick up gapped pretty far from the bump on the flywheel. Also pulled the flywheel again to make sure it was on the key straight. It was and is now too. I'm not using a degree key. Tell me if you think being this far away may have caused some of what I was experiencing. I have it set now to about .025-.030 gap. It's as close as I could get it. pick is before the fix btw Quote Link to comment Share on other sites More sharing options...

It's as close as I could get it. pick is before the fix btw im not 100% but if you have too much of a gap that would just casue you to lose spark because your not pulling as much of a current of the stator. shouldnt make you detonate... thats a matter of your fuel combusting too soon and if your losing spark that would be the opposite.
