Title: new symptom my clutch began to slip today Post by Greg on 04/19/14 at 18:19:53 I went for a 90 mile ride. Mostly 40mph but was between 25 and 55. The bike ran great for the trip. I parked about a half hour. When I left, the clutch was slipping terribly in 1st and second gear. It was as if I kept the lever pulled in. As I headed back, it was slipping in higher gears with just a slight twist to maintain speed going uphill. As time went on, it got better. After about 25 or 30 miles it would only slip under hard acceleration and not all the time. The oil and filter was changed a couple hundred miles ago. I used Rotellla T. The last oil change was also Rotella T but no filter. Before that was Spectra semi synthetic oil and filter. I only change the oil yearly. It is a 2002 with 13Kmiles. When I looked at the oil window, it was way over filled. I thought fuel got in there so I changed the oil again today. There was no fuel smell in the oil. It still slips under hard acceleration. Did the Rotella formulation change? Can my clutch be worn in only 13K miles? I don't slip it when I ride. Heck, I get 125K miles out of a car clutch. Research on this site mentions springs. Can I add ZDDP to help? |

Title: Re: my clutch began to slip today Post by Greg on 04/19/14 at 18:28:03 I saw that. It isn't a free play issue. I have about a quarter inch at the lever. Unless you are saying I need to clean the clutch but I use Rotella oil. |

If it was my bike I'd be real curious about where that extra oil came from. I'm probably way off base here, but it makes me wonder. Where was the bike parked for that 1/2 hour. Is there any possibility that someone screwed with your bike ? Put something in the oil? Quote:
ZDDP is added to protect the cam lobes and rocker arms from excessive wear. It can only affect the clutch if you put the WRONG additive in - one that is not recommended for wet clutches. A lot of the stuff for sale in auto parts stores is exactly that. It has chemicals in it that will make a clutch slip. |

Title: Re: my clutch began to slip today Post by Greg on 04/19/14 at 19:20:03 No. It was within 15 feet of me. I figured it was fuel or more likely I over filled it when I changed the oil. |

Title: Re: my clutch began to slip today Post by 1st2know on 04/19/14 at 19:27:44 Check to make sure your clutch cable and actuator aren't sticking. These things are exposed to the elements, and can jam without warning. |

Title: Re: my clutch began to slip today Post by Greg on 04/19/14 at 19:28:50 I was thinking I should pick up a cable lube tool. |

Title: Re: my clutch began to slip today Post by 1st2know on 04/19/14 at 19:38:46 I can ask my pharmacist for a 3cc syringe, and they just give it to me for free...they don't even ask me what I need it for. Ask for one with a blunt tip. Get the syringe, draw up 3cc's your favorite lube (I like Hoppe's), and squirt it in the top of the cable housing with the syringe. Then work it down by moving the cable until it seeps down and out of the bottom. |

Title: Re: my clutch began to slip today Post by Greg on 04/20/14 at 09:47:55 I added even more slack and am currently giving the cable an oil IV. |

Title: new symptom Re: my clutch began to slip today Post by Greg on 04/21/14 at 11:01:41 I think I have another clue/symptom for you folks to consider. When I adjusted my clutch cable yesterday, I added more slop by making the adjustment at the engine. When I took my cable off of the lever to do the oil IV, I cranked the lever adjuster in all the way. Now of course there was a lot of play in the lever. When I put it all back together this afternoon, there was zero play at the lever with the adjuster in all the way. I checked at the engine and the adjuster was seated all the way down. I pulled and released the lever many times but it never changed. I had to make additional adjustments at the engine to give it any slack. My question is: is there anything inside that can cause this? I took it for a short ride and everything was fine. I really need to get out later and do a thorough test though. Anyway, will something in there move and give me too much slack so the clutch doesn't disengage? Why did it change without any adjustments? |

Title: Re: new symptom my clutch began to slip today Post by MMRanch on 04/22/14 at 07:06:21 Greg I've put 42K miles on my first one and 16K miles on my second one, and have been all through these motors. I'd be wondering what happened too. If you will lean your bike way over on the kick-stand side (milkcrate with a pillow) then you can pull the clutch cover without draining the oil . I'm thinking your clutch springs have worked loose (thread-lock). Also that short rod that runs between the pusher on the clutch cover and the throw=out bearning , if its too long your clutch can't close, you check it befor you put the cable on (just a little slack is all you need) Back to your main problem ... did the springs work loose ? or did someone punk-ya with some STP in your oil ? :) |

Title: Re: Yes, I have been butthurt Post by Serowbot on 04/22/14 at 05:08:37 Looking at your latest symptom... (if I'm understanding correctly),.. it seems cable related... Might be frayed, or routed in a way that is binding... I might suggest pulling it off the bike completely, and and giving it a careful inspection... Lube it good, then reroute it back in place...(slightest kink or binding and you should replace it)... One other remote possibility... check your front pulley nut... If it got loose, it may have eaten the shaft splines, and be slipping... (pray it ain't so)... If those don't get it... I think yer' going in deep to look at the clutch itself... |

Title: Re: Yes, I have been butthurt Post by arteacher on 04/22/14 at 07:19:19 If it was a cable problem wouldn't the clutch lever control go slack if the cable was binding? |

Title: Re: Yes, I have been butthurt Post by WD on 04/22/14 at 08:23:30 Went and read it back over. If fiddling with the cable does nothing, time to open her up. Check the springs, and if they are tight, tear the clutch apart. Sounds like you glazed a steel or wiped a fiber, but you could also have a failing "paddle" where the cable arm actuates the pushrod. If you were on a bike with a "normal" metric single spring clutch (VN1500 and such), it would be easy, the spring got chewed up. The 1960s clutch in a Savage is an entirely different design, miniaturized Harley Davidson crossed with Honda locating tangs. The factory clutch discs are crap. The same cheap fibers and cut rate steels you would find in an Emgo kit. If you ride the bike like a sedate little cruiser, they last a long time, but if you get spirited, especially running lightweight synthetic oil, they'll give up the ghost. I ran fresh Rotella T6 5W40 in my 03 for one day, commuted to work and back home, and changed it out for Rotella 15W40. This makes 2 Savages for me that do not like synthetic oil. Clutch issues, noisy valve train, leaks... Pop both outer cases off, flush the clutch assembly with contact cleaner, and take it apart. Stuff rags in the big inner case passages so you don't lose any hardware into the transmission. Clutches, like batteries, either work or they don't. |

Title: Re: Yes, I have been butthurt Post by Steve H on 04/22/14 at 20:30:11 My clutch slips in 3rd and 4th gear under heavy acceleration. Other than that, it's fine. I just roll on the power instead of romping down on it at 60 and all is well. I know it's a different problem than yours. Just saying I don't know what to do for it either. That's why I haven't ventured a guess. Although, the little rocking thingy inside the case does sound plausible especially with the amount of slack varying on you. |

Title: Re: Yes, I have been butthurt Post by Serowbot on 04/22/14 at 20:40:10 Under WFO acceleration... I believe it is normal to get a second or so of slip going into higher gears as the plates have time to engage... I like to call this..."Dang'it what's wrong with this thing?"... :-?... |

Title: Re: Yes, I have been butthurt Post by justin_o_guy2 on 04/23/14 at 12:26:44 If youre not letting it tach down & just fanning the clutch & grabbing a gear, it MITE slip a tad, but if it starts tachin up & not accelerating at high speeds in high gear, youve got a booger,, |

Title: Re: Yes, I have been butthurt Post by HondaLavis on 04/24/14 at 19:35:50 Lots of good responses here. Seems like everybody is on the same page. Sorry you didn't get more attention before. Sometimes to become an oldtimer you have to find a problem that nobody has the answer to. Then you have to dig, research, and blaze the trail. We might not always have the answer, but we'll definitely support you if you've got to go in. ;) |

Title: Re: new symptom my clutch began to slip today Post by Dave on 04/29/14 at 05:13:31 I currently have a stock clutch, a modified engine, and tall gearing. I have never had any clutch slip as long as the throttle is released between shifts, and the clutch lever is fully released before you grab a hand full of throttle. I do believe I have experienced a slip once of twice prior to the engine being fully warmed up. Also if I get in a hurry and apply full throttle prior to the clutch lever being fully engaged....the clutch will slip until you let off the throttle and let the clutch engage. The clutch just doesn't have enough grab to stop the slipping once it starts when full throttle is applied. I bought some Barnett Kevlar discs and will put them in some day, and I have some EBC 10% stronger springs to install - but if I make sure not to apply full throttle until the clutch is fully engaged......I never have any problems. The stock clutch is adequate to handle a stock engine and gearing, and if you are having slippage under application of throttle alone - then you either have an adjustment issue....or plates contaminated with friction modifiers from engine oil that isn't compatible with a wet clutch. |
