Title: Cam chain tensioner mod question Post by cheapnewb24 on 08/09/16 at 13:53:45 Alright, I got my head bolt drilled out. I'll tell you about that later. I am about to let that same machinist do my tensioner mod too. We pulled the case and removed the tensioner to inspect it. We weren't quite settled on the exact specifications of the mod. For a long time, he was afraid to extend it much because he thought there would be too much pressure. But I could compress the spring into the eyelet end tube shaft with my thumb and I could put the thing together and compress it with my bare hands. I let him handle it then, and he said it wouldn't be too bad. He was also very doubtful about the necessity of the roll pin. He said that the chain would come together and be ready to break at that point. But as I'm writing, I just figured it out. The biggest thing that's for is for the first eyelet on a new chain. So if I buy a new chain, the roll pin will matter more? Probably? Anyway.... Here's a question that might interest you that might never have been asked. Would it benefit me to shorten the spring? I seem to recall one person actually replacing the factory spring with a weaker one in order to reduce wear on the chain. Any comments on the amount of compression? 2-3 teeth out on the shaft doesn't seem too bad. As long as it catches one tooth, it ought to work okay. I'm going to do some final research tonight and take it to him in the morning to get the job done. He's going to leave for Florida Thursday, so I need to get this figured out tonight. I appreciate your feedback if you have any. If Verslagen isn't interested in helping, I can respect that. [smiley=dankk2.gif] Thanks, Cheapy |

Title: Re: Cam chain tensioner mod question Post by stewmills on 08/09/16 at 13:59:19 My advice: Feedback will hopefully be provided. If so, USE IT. These folks know what's going. Skilled as your machinist may be, he doesn't know this bike! Good luck! |

Title: Re: Cam chain tensioner mod question Post by SavageMan99 on 08/09/16 at 14:11:19 Here is my 2 cents worth, or maybe worth a hay penny... Look at a pic, judge it by the size of the original hole, is there one holes space between the two holes? |

So, to get full stretch add another hole. And yes at 19mm spacing, the chain will get real close to locking on itself. So you don't need that much, 5/8 is fine. And it will push the plunger back in to day 1. Quote:
Grenades need a pin, if he doesn't want to do it, send it to me with $10 and it'll get done. Quote:
So if you shorten the spring by a couple of coils, you remove the pretention, but as you compress the spring it is stiffer (less coils, same compression, get a degree and you'll understand) So unless you can find a spring with the same number of coils, same length but smaller wire diameter, I don't think it's a benefit to shorten the spring. Quote:
As long as the pawl engages the plunger fully, no problem. |

Title: Re: Cam chain tensioner mod question Post by cheapnewb24 on 08/09/16 at 15:31:57 Thanks, Versy. I really appreciate your help. I was tempted to disagree on the spring thing, but I think I understand now. While shortening it will remove the length of spring to be compressed, which would give the impression of lightening the load, it cancels itself out when you consider the fact that each little bit of that spring compresses (or gives a little, and when you remove a piece, it can't compress as far as easily because there's not as much material left to give. Am I on track here? If I have issues with this guy, I'll certainly send it your way. :) |

Title: Re: Cam chain tensioner mod question Post by cheapnewb24 on 08/10/16 at 09:52:43 Got it modded. Paid $100 for it. The maximum travel is now 18 mm. I was indecisive about how far to drive the roll pin, and he drove it slightly too far. It rubs the spring a little. He thought it would be okay. What do you think? |

Title: Re: Cam chain tensioner mod question Post by cheapnewb24 on 08/10/16 at 09:58:32 Hey Verslagen, do you think the cheap chain they use in these things just hasn't been properly stretched or broken in? I gather you've driven your modded bike for a long time. Doesn't it still have the original chain? |
|
Title: Re: Cam chain tensioner mod question Post by verslagen1 on 08/10/16 at 10:00:24 Might be ok if you have a new style spring. Not ok if it's an old style, the bigger diameter jams. |

New isn't stretched or broken in. Cheap usually stretches or breaks. So... you're broken shiny thing? :-? |

It's a 2004. The spring is considerably smaller than the hole. Does that sound about right? I can remove the tensioner and post a video of its movement if you need me to. |

Title: Re: Cam chain tensioner mod question Post by cheapnewb24 on 08/11/16 at 18:07:47 I pulled the tensioner to make a video for inspection purposes, and put it in the house since it was late. I then decided I would pull the clutch bolts in order to inspect the clutch plates and such. While breaking a bolt loose, the engine ploped over a bit. I then realized that, without the tensioner, there is the possibility that the cam chain could jump time. Should I be worried??? I know... I know... Just call me Dennis... ::) |

Title: Re: Cam chain tensioner mod question Post by cheapnewb24 on 08/11/16 at 18:26:56 What do you think? Did he do a good job? Is it safe and good to go? Seems like it's not rubbing quite as bad as it did before. https://www.youtube.com/watch?v=EKnrQpQAMh8&feature=youtu.be [media]http://www.youtube.com/watch?v=EKnrQpQAMh8&feature=youtu.be[/media] I discovered that my clutch nut is a little loose I can wiggle it with my fingers. The lock tab is still bent up to hold it, though. Could that be causing any issues? It was getting dark, so it's pretty hard to see what's going on. https://www.youtube.com/watch?v=TillY99Cxkw&feature=youtu.be [media]http//www.youtube.com/watch?v=TillY99Cxkw&feature=youtu.be[/media] By the way, my clutch rod external measurement is approximately 12mm. |

Title: Re: Cam chain tensioner mod question Post by verslagen1 on 08/11/16 at 21:46:05 looks like a good job, grind that roll pin back near flush. The action looks good, I hear it clicking, but it doesn't go that fast. 12mm [smiley=thumbsup.gif] I tried to see if the chain will jump with the tensioner out and I couldn't do it... but I know you're special. ;D |

Title: Re: Cam chain tensioner mod question Post by cheapnewb24 on 08/27/16 at 18:47:49 Got the excess ground down on that roll pin. Put it in. Recently I found the following photo in the Motorcycle Handyman download. I used the old circlip, and I've noticed that there may be some concern about old circlips. Should I be concerned? Is this a worthwhile mod, or will the silicone peel off and stop up the engine? :-/ Not sure I have the right type of RTV. |

Title: Re: Cam chain tensioner mod question Post by justin_o_guy2 on 08/27/16 at 19:15:00 Circlips that are not distorted are fine to reuse. If it needs goo to stay in place, you need a new one. Ifit Pops into place, it's good. Have you reinstalled the sidecover? |
|
Title: Re: Cam chain tensioner mod question Post by cheapnewb24 on 08/27/16 at 19:35:13 I still have to put the clutch back. ;D ... amongst other things I just have the cover on for weather. right now. I seem to remember that the clip is easy to move around. :-? It's been put back on a few times. Can't say there's anything wrong in particular. :-? I don't know... |

Title: Re: Cam chain tensioner mod question Post by justin_o_guy2 on 08/27/16 at 19:52:21 They can be reshaped, but they are brittle. Just go to a hardware store and get a new one. I made do fixing copiers, but the price of failure is different. |

Title: Re: Cam chain tensioner mod question Post by cheapnewb24 on 08/27/16 at 20:01:26 Hey, I just thought of it. I wonder if I have some... :-? |

Title: Re: Cam chain tensioner mod question Post by justin_o_guy2 on 08/27/16 at 20:42:06 Putting something INSIDE THE ENGINE That you don't Trust Isn't just Cheap. It's dumb. If you glop RTV on it and Wonder if said RTV could come off and plug something up, what are you Thinking? For what? The price of a Circlip? You would risk seeing the tensioner without a retainer and the circlip loose in the engine? Change your name. You're not that new Nobody is that cheap. And how is it Cheap Risking engine damage instead of spending pennies on a clip? I'm wasting my time.. |

Title: Re: Cam chain tensioner mod question Post by justin_o_guy2 on 08/28/16 at 03:52:02 What if I can't find anyone around with an appropriate snap ring? So, since you can't Know the outcome of a search, that, somehow, justifies Not Looking? Do you even have a clue just how ridiculous that excuse for a logical position Is? You Might have an assortment at home, but , you didn't think to look,while you packed goo on the thing, then TOOK A PICTURE of it, and asked Gee, guys,how stupid is this? Will the goo cause problems? Ask, get advice, THEN DO. Nobody can see the condition of the clip now. So, since you aren't SURE the food you want is in the kitchen, you'll just sit down and be hungry? |

Title: Re: Cam chain tensioner mod question Post by justin_o_guy2 on 08/28/16 at 11:04:18 My FORMER SIL is, was, a failure. He seemed satisfied that he always had an excuse. I pointed out that when he had nobody left to keep him afloat, then excuse or no excuse, when he was homeless, he'd just be homeless. Parents only support for so long. He didn't stay out of jail for long after I threw him out. If it's not organized, organize it. If you're lazy, organize it. It's easier to live in an organized place. Takes less effort to get through the day. I am ready for the new screen name. You're not a newb anymore. And there's nothing attractive about the name. Surely you can harness the OCD and sit flat on your lazy butt and make a list of names. Ohh, do it scientifically. Ten that start with each letter.. I'm not even reading the crap you write. If you don't get it together, pay attention, ta k e action,, you'll be the first member to achieve alienating the whole group. Have you performed any tests on the TW? Have you twisted off any bolts? I've never seen anyone proclaim their laziness as if it's something to boast about and is an excuse for doing nothing. I'll reply when you announce results. Excuses for doing nothing will get nothing. I still haven't seen how much of your life have you spent playing video games. Why do I suspect that it's a substantial amount? Kenny , Yes, I suspect you're right. I don't know why I try. I can just see his dad, so sick of telling him what to do and how to do it that he either just lets it go undone or wordlessly just Does it. I'll bet he just walked in, grabbed the drill, and nailed the busted exhaust bolt. Too bad CN was able to find the never used, God knows where they were, EZouts. I wonder if dad mumbled something about Keep drilling it out, and tap it. |

Title: Re: Cam chain tensioner mod question Post by cheapnewb24 on 08/29/16 at 16:53:55 Well, here's your results, Justin. I had to go buy some fasteners to replace some lost ones. I wasn't very happy earlier today. :( He had some 8mm snap rings in stock, so I picked one up while I was there. You can see how the old one was spread. Not good. I didn't know until I had a new one to look at. I found my snap ring pliers, so things are going okay. Sorry for the double image. You can still see how far the old one was spread. |
