Title: oil and sediment in carb? Post by ksthumper on 06/29/11 at 09:39:33 Went to clean out my carb and do the spacer mod and got an interesting surprise from the last time I cleaned it out. http://i1200.photobucket.com/albums/bb331/milkandcookie2000/IMG_0146.jpg http://i1200.photobucket.com/albums/bb331/milkandcookie2000/IMG_0147.jpg The bowl was previously clean and clear of stains... I had a nice line of sluge in the bottom carb bowl and the gas that I poured out had a oil sheen to it. Does this mean that my intake valves are not set correctly and allowing crud to come through? And does the this look normal for the floats to be so tarnished or is that just tinting from them sitting in a mix of gas/oil? http://i1200.photobucket.com/albums/bb331/milkandcookie2000/IMG_0148.jpg |

Title: Re: oil and sediment in carb? Post by drums1 on 06/29/11 at 09:47:19 Possible diaphram leakage. The floats actually look rusty. If that thing was all cleaned...how long ago?...I might suspect something nasty going on in the gas tank. Have you changed the gas filter ever? How's it look? Intake valves? Could be, but if they were that far out I would think you'd be hearing some loud ticking. Timing chain may have jumped? Have you checked the tensioner adjuster lately? And how is it running otherwise? I assume you do have an air filter on there... |

Title: Re: oil and sediment in carb? Post by ksthumper on 06/29/11 at 09:52:16 I had it all opened up and cleaned about a month ago. Had the valves adjusted too at the same time and I can't really hear any lifter ticking. Spaced them at .004/.005 but I haven't opened up the panel to double check that yet today. Running wise 1/2nd gear stutters till i get about mid throttle and then it runs like a bat outta hell. I do have the plug to seal up still so I have oil from that leaking about but it hasn't caused a problem yet. |

Title: Re: oil and sediment in carb? Post by ksthumper on 06/29/11 at 09:53:50 and I did a bit from the gas tank and that is clean of oil. Tensioner chain hasn't been checked and from what i can remember hearing when it was running it didn't sound like it was loose. |

Title: Re: oil and sediment in carb? Post by Serowbot on 06/29/11 at 10:24:45 Don't look so bad to me... The floats can't rust... they're brass,.. or maybe copper... That discoloration is just lacquered gas,... no biggy on the floats, but that's what plugs up the jets if the bike is left sitting... of course, gas is sitting the bowl all the time anyway, so that's just normal... Putting a filter on your gas line will help with the sediment ... maybe you got particularly yukky batch of gas... but I don't think there's a valve problem... |

Title: Re: oil and sediment in carb? Post by ksthumper on 06/29/11 at 10:31:24 But what about all the gunk on the top diaphram cover? I cleaned all that out with dish soap and was surprised with what all came off. |

Title: Re: oil and sediment in carb? Post by Serowbot on 06/29/11 at 10:46:25 Do you have an oiled foam or k/n air filter?... You might have too much oil on it... ...or... it's just blow by from the crankcase... Think of it this way... It's keeping your slide nice a lubed... ;D... Check for excessive oil build up in the the filter box,... but I wouldn't worry 'bout it... Do you ever drain the filter box?... There's a hose that comes off of it, goes to the ground, but it's capped... drain it when you do oil changes... It's there to collect the normal blow by from the crankcase... ;)... |

Title: Re: oil and sediment in carb? Post by ksthumper on 06/29/11 at 17:22:15 ack I forgot about that drain tube even though it's just dangling there like a ... yeah. I'll check more parts tomorrow but hopefully you're right about the blowback on the crankcase. |

Title: Re: oil and sediment in carb? Post by Boofer on 06/30/11 at 11:36:11 ksthumper, It looks to me that is the work of water in the gas, improper storage letting water in, or Ethanol fouling. Take a good look in the tank to see if it looks the same. I am a believer in Seafoam, so I would clean it thouroughly and run Seafoam about once a month to keep it clean. I have a small medicine cup (who needs a cup for NyQuil?) I use to put about 2 oz in a full tank. |
