Title: Plug… Post by Theduderino on 12/30/21 at 11:23:14 PWK 40 mm. This is a pic of the plug. I need the good the bad the ugly. |

Title: Re: Plug… Post by Theduderino on 12/30/21 at 11:23:56 Looks a tad rich to me… |

Title: Re: Plug… Post by Armen on 12/30/21 at 11:42:53 Give us a shot into the recess of the insulator. Looking at the side doesn't tell us much. |

Title: Re: Plug… Post by justin_o_guy2 on 12/30/21 at 17:38:16 So, did you blow the crap out of the recess that plug sits down in before you pulled the plug and let it fall in? |
|
Title: Re: Plug… Post by Yoshi on 12/30/21 at 17:46:30 Looks like a good old plug, for the price just get a new one |

Title: Re: Plug… Post by Theduderino on 12/30/21 at 18:02:04 Hopefully this is a better shot |

Title: Re: Plug… Post by Theduderino on 12/30/21 at 18:03:57 Hey Mr. V, How come everybody I talk to is running like a 50 pilot jet and a 155 Main I’m assuming they’re referring to the stock carburetor? Because I have a 40 mm PWK and it seems to like a 35 pilot and a 158 mean? Should I be going up on the pilot? I know there’s tons of info out there I just wanted to get your opinion |

Title: Re: Plug… Post by Theduderino on 12/30/21 at 18:04:21 Also I will be ordering one of the tensioner‘s for me real soon… |

Title: Re: Plug… Post by Armen on 12/30/21 at 21:46:07 Not a great pic, but it def does not look rich. |

Title: Re: Plug… Post by Theduderino on 12/30/21 at 21:59:29 My bad … Funny story, on my road trip for work which I’m about to embark on once again, I have a stop in Linden NJ… Then on to Boston, Well Plainview New York first I think… I think it’s pretty cool up there. |

Depends on the year, for a pre 90, this is stock (almost) I don't have a stock carb and I run a 5K needle. I sure that doesn't anything to you. you don't have a stock carb, so I don't know what you'll run. If it starts and runs good... and you have good mpg, that's great. Don't F it up. Plug looks a shade lean, what color is your header? What's your mpg? How wide's your grin? |

Title: Re: Plug… Post by Theduderino on 12/31/21 at 06:21:46 Grin is pretty wide…lol… At the risk of sounding like a bonehead, how do you guys time yourselves I mean I don’t have a Dyno in my backyard. I mean I know when she’s running like crap and when she’s not. like drag bike Mike, he’s posting about you know second gear gains of .33 seconds. I was just curious on how One could time themselves. I mean last time I checked it takes two hands to operate the bike let alone introduce a stopwatch |

Title: Re: Plug… Post by Theduderino on 12/31/21 at 06:24:14 Also my header is wrapped… it was nasty when I got the bike that’s why I rewrapped it. But here’s the muffler. Looks like it’s running rich to me. |
|
Title: Re: Plug… Post by Armen on 12/31/21 at 06:30:25 Not sure why you think the pipe says you are running rich. That kind of discoloring is from running hot, which means running lean. Plug looked hot/lean. |
|
Title: Re: Plug… Post by Theduderino on 12/31/21 at 06:44:46 I thought if it was brownish it was running rich and purple/blue was lean? |
|
Title: Re: Plug… Post by Theduderino on 12/31/21 at 06:45:18 I am starting over with a 50 pilot and 155 mange it this morning we’re going to see how this goes |
|
Title: Re: Plug… Post by Armen on 12/31/21 at 07:27:22 If you are talking about the head pipe, the chrome discolors when it gets hot. Lean running makes the bike run hotter. I’ve seen Savages discolor the head pipe all the way back to the muffler joint. |

Title: Re: Plug… Post by TheSneeze on 12/31/21 at 07:51:01 Use a GoPro camera. of a cell phone on a mount to take video. Use the same section of road, in the same direction each pass. When you upload the video to your computer, you can time the distance between land marks on each pass to find out the change. |

Title: Re: Plug… Post by Theduderino on 12/31/21 at 08:09:46 OK just ran it with a 55 pilot and 155 main, at first the idle wanted to sound like a Harley but I got that squared away, then dropped it in the first and holy nuts she’s running like she supposed to. backfire is all but gone, with a 35 pilot and 158 Main, every time I would downshift it sounded like I was being chased by the Taliban. Now there’s no popping between gear shifts.. |

Title: Re: Plug… Post by Gary_in_NJ on 12/31/21 at 10:03:45 The plug is dry and the insulator looks clean (and green). This bikes jetting could stand to be richer on the pilot, but mostly on the needle. Look up the white spacer mod…and note the use of #4 washers as an alternative to resizing the spacer. |

Title: Re: Plug… Post by Theduderino on 12/31/21 at 10:08:03 Gary, its a PWK 40mm I have it on the fourth groove towards the rich side |
|
Title: Re: Plug… Post by Gary_in_NJ on 12/31/21 at 13:45:55 Sorry, I didn’t pick up on that. You may need a richer profile needle. If there is another clip position, give it a try. With that said, while plug reading is a good confirmation of what you are feeling, it’s best to jet for best throttle response. |

Title: Re: Plug… Post by DragBikeMike on 12/31/21 at 15:03:12 Dude, please don’t take offense. I can’t understand half of what you ask. It’s also very frustrating to go through a lot of trouble to provide you with detailed advice only to have you completely ignore it. First, your plug looks OK except for some balls of crud in the shell. Hopefully those are combustion products and not metal. Metal balls usually accumulate on the ceramic insulator when you have problems with overheating and/or detonation, but I suppose they could also accumulate on the metal shell. I assume you are running unleaded pump gas. Your color looks OK as best as I can tell from a photo. Also, plug color checks aren’t much use unless they are performed in a specific manner, which I’m not gonna go into. For now, let’s just say that aside from the balls on the shell, it doesn’t look like anything bad is goin on. But if the balls are metallic, you might be hurtin it. Keep in mind you were runnin it with the main jet closed off by the drain plug, so any metallic deposits might have accumulated during the time it was grossly lean. I circled the balls in yellow. Sorry, I can’t enlarge your photo, don’t know why. |

Title: Re: Plug… Post by DragBikeMike on 12/31/21 at 15:05:30 You are running a #8 spark plug which is the correct heat range. You might wanna switch to a #9 if it will tolerate the colder plug. The discoloration on your muffler could be caused from a catalyst. I’m not sure exactly what muffler you have, but in a prior post you said it was a Dyna muffler. You provided a picture into the muffler taken from the rear of the bike. It’s hard to see, but it almost looks as if someone punched through the center plate and exposed the catalytic element. Hard to tell from the photo. Dyna mufflers with a catalytic element run real hot, like glow in the dark hot. That’s because they weren’t intended to be run with a carburetor, which generally runs much richer than a fuel injected system. If you look in the inlet side of your muffler, does it have one of these honeycombs? Can you see anything like this if you look up the rear end of the muffler? If yes, then that’s why the outside looks overheated, because it’s overheating, because it’s got a catalytic element. I doubt you will be able to correct that running a PWK. |

Title: Re: Plug… Post by DragBikeMike on 12/31/21 at 15:08:32 You say you are running a #35 pilot jet in your PWK. That should be correct. Based on what you say, it sounds correct. Your needle jet size is unknown, and your needle size and taper are unknown. I can’t help you with the needle jet and needle because I have no idea what you are working with. Based on what you say, it sounds like the needle jet and needle are working good. Reply #19 today: “holy nuts she’s running like she supposed to”. I continue to be totally bamboozled about your main jet. A #155? A #158? What are these jets? Where did you get them? Are they Keihin jets? Mikuni jets? Custom handmade jets? For example, a Mikuni #155 hex jet for a VM has a .044” hole, while a Mikuni #155 large round jet for a BS40 has a .064” hole, while a Keihin #155 long hex jet for a PWK has a .060” hole. What sort of #155 main jet do you have in there? Picture please? I’m glad you are having fun with your Savage HotRod. It sounds like the PWK works good. Do I have that correct? |

Title: Re: Plug… Post by Theduderino on 12/31/21 at 20:58:17 Yes sir I am having a great time with her !! Since I did the mods that you covered in our forum! But I digress, I did not get them from jets or us. I ordered them off of Amazon. Ordered probably two sets of each of these different configurations. Didn’t like the smallest one. I just got in the short hex Jets today and like you said, ordering these Japanese or knock off jets no Bueno. I had to take a sixteenths inch drill bit into one of these jets I just got today but I haven’t ran it yet busy partying for New Year’s but had time to look on this lol , rule number 1/no riding motorcycle while intoxicated! |

Title: Re: Plug… Post by Theduderino on 01/01/22 at 21:43:05 I guess I’m a huge proponent of learning the hard way. Do you not, and I repeat do not buy jets from Amazon. Do as drag bike Mike says and get them from a reputable place. Also, DBM you’re gonna love this stuff. I’m sure you were familiar with how far out my main jet was sticking into the bowl cap? I had taken the Main out 100 times… than the last time I take it out this little fella falls out behind it. |

Title: Re: Plug… Post by Theduderino on 01/01/22 at 21:44:35 Lookin better? |

Title: Re: Plug… Post by Theduderino on 01/01/22 at 21:46:27 Also here’s a picture inside of my lower G.I. (inlet side of muffler) |
|
Title: Re: Plug… Post by Theduderino on 01/01/22 at 21:49:15 It appears to me to be like a diverter inside of the muffler so it cannot resonate back towards the engine. No honeycomb stuff. |

Title: Re: Plug… Post by TheSneeze on 01/01/22 at 21:57:19 That looks loud... |

Title: Re: Plug… Post by Theduderino on 01/02/22 at 03:38:11 Sounds ( larry david for curb your enthusiasm fans, pretty,pretty,pretty good). |

Title: Re: Plug… Post by Theduderino on 01/02/22 at 03:40:51 Hey sneeze, did you see my main jet post? |
|
Title: Re: Plug… Post by Theduderino on 01/02/22 at 03:42:37 It’s in the plug post but previous page |
|
Title: Re: Plug… Post by TheSneeze on 01/02/22 at 08:18:49 About the height of your main jet to the float bowl, or about the part that fell out? |
|
Title: Re: Plug… Post by Theduderino on 01/02/22 at 11:38:07 Both.. :o |
|
Title: Re: Plug… Post by TheSneeze on 01/02/22 at 12:13:58 When I removed my main jet there was only a washer between the jet and the carb body. Also, my jet does not stick out as far as yours. It is recessed into the bowl when you remove the plug. |

Title: Re: Plug… Post by TheSneeze on 01/02/22 at 12:14:32 jet & washer |

Title: Re: Plug… Post by TheSneeze on 01/02/22 at 12:14:58 carb body |

Whoa! That kinda looks like it might be the normal, stock PWK needle jet. Do you think someone might have tried to repair the carb? Maybe the fit between the normal needle jet and the metering block was loose so they tried to capture the jet with that contraption you refer to as the "extender". Have you tried running it without the piece that fell out? Regarding your muffler, it doesn't look like it's a genuine Harley part. To me, it looks like an aftermarket item, or possibly a Screaming Eagle muffler. I believe some of your pictures that you posted were taken before you started messing with the PWK. If that is correct, your muffler was discolored prior to the PWK install. Do you agree? |
|
Title: Re: Plug… Post by Theduderino on 01/03/22 at 06:22:01 Very possible, I’m going to take the carburetor out today, as I have the day off. I started fooling with the float level; now the SOB wont start: i’m going to take some quality pictures of the carburetor. So I can get yawls feedback. Also the carburetor has been straight out of the box onto my motorcycle. Unless somebody may be returned it or something I don’t know. Yes I tried to run it with a piece that fell, out wouldn’t start. That little piece gets inserted on top of the needle jet: |
|
Title: Re: Plug… Post by DragBikeMike on 01/03/22 at 11:07:05 Can't wait for those quality pictures. This is an illustration (cross section) of a normal PWK needle and needle jet. Make sure you install that suspect needle jet (the piece that fell out) as shown in the illustration. The side with the larger opening goes "up". |
