Title: How much oil should be in the head cap? Post by Mattdw on 09/18/09 at 07:10:08 Ok...I "think" I have the infamous head plug leak. I have oil on the fins, etc. I took off the head cap last night, and the wells around the valves were mostly full of oil. Is this normal? The head cap that was in there, was the old style, but was in TIGHT. There wasn't any sealant around it though. I couldn't really tell if it was leaking per-se, but, I know old can get through the slightest gap, even if not visible. Also, I'm not sure how well the previous owner took care of her, so I doubt they did any of the beginning maintenance. Is there any harm in re torquing the head bolts while I have the cap off? Should I be able to get to all the bolts requiring re torquing with the engine in the frame? Also, some of the bolts I took off the head cap were difficult to get to, so I had to use a variety of my tools. I KNOW I won't be able to get to all of them with my torque wrench when putting back on. Do they ALL require special torque, or is it 'OK' to just apply the torque wrench to the bolts I can get to and just be gentle (but not too gentle) with the ones I can't? |

Title: Re: How much oil should be in the head cap? Post by justin_o_guy2 on 09/18/09 at 07:17:13 The amount of oil in the head cap varies from guy to guy. If ya wash yer hair a lot, less oil, you see? There is a pool of oil in the head the cam runs in, IDK about oil standing around valves, I dont remember that, But, If you are in there, pull the plug & clean carefully the plug & where it seals off, goop it up, or, for all the trouble, I would get a new plug, if thats the stock one. Is there any harm in re torquing the head bolts while I have the cap off? Thats the required procedure. |

Got the new plug already, plan on installing it later, just didn't want to put it all back together until I was sure about the torquing issues and maybe torquing the head bolts too...wanna make sure I do everything I can while I have the cap off. |

Yep...I have the manual, patience, and experience...just needed some expertise on what I should do while I have the top off :) Then of course, adjust the valves, and the decomp solenoid when I get it all back on. |

Title: Re: How much oil should be in the head cap? Post by justin_o_guy2 on 09/18/09 at 07:23:04 Ive never had to adjust the decomp, & thats cool, cuz frankly, I dont "get it" looking at the picture.. |

I haven't had to adjust it yet, but I "think" I understand what needs to be done. |

About 5mm as I recall.[/quote] Looking at that picture is like looking for your keys in the bottom of a muddy pond. And to make it a little clearer... the measurement is done on the buttom under the rubber cap on the solenoid, the adjustment is on the other end of the cable. And you never see it operate so how do you know it works? If you have an occasional problem starting, it's too loose. |

Title: Re: How much oil should be in the head cap? Post by verslagen1 on 09/18/09 at 08:50:57 BTW, remove the head nuts and oil the threads before torqueing them. |

Title: Re: How much oil should be in the head cap? Post by justin_o_guy2 on 09/18/09 at 09:41:02 If ya remove all of themn at the same time, will you lose the head gasket>? Or only if you pull the head off? |

Title: Re: How much oil should be in the head cap? Post by justin_o_guy2 on 09/18/09 at 12:53:50 Ive come pretty close to needing anew gasket several times. Ive upset some bigger guys real bad. Thot sure they wuz gunna pull my head OFF. |

I wanna make sure I understand....REMOVE the head nuts before re torquing ? Can I get to them all (how many?), while the engine is in the bike ? |

You really need to get one. There are several steps that you need to follow in order to get to the head nuts. And you'll cause damage if you don't follow them. |

Title: Re: How much oil should be in the head cap? Post by verslagen1 on 09/18/09 at 22:01:57 great, look in the maintenance section towards the back if you got clymers, you'll see a pic of the head with 4 arrows around #110. find the paragraph and start reading. |

Title: Re: How much oil should be in the head cap? Post by grandpa on 09/19/09 at 05:30:13 The way I do the decomp solenoid is to stand beside the bike looking at the solenoid. Reach under it and squeeze it to push the shaft out the center of the solenoid. That is where you measure it. Can't remember the measurement off the top of my head. The cable that pulls the cam to open the exhaust valve will stretch over time, not opening the exhaust valve enough and causing strain on the starter and battery. Took me a while looking at both the Clymer's and the service manual to get it. Neither one has a good description, just do it!! |

Title: Re: How much oil should be in the head cap? Post by genejohnson on 09/19/09 at 14:26:07 I read you guys saying the plug is made of rubber? The valve cap doesn't get hot enough to burn rubber? If it doesn't, has anyone thought about trying to use "Baitwell Plugs" as used on boats? They have means of internally tightening the fit in the hole..... and some sort of sealant could be used as a backup> Gene |

Yep, there are several head cover bolts you probably can't get a torque wrench on. Yet, I think proper torque of ALL of the myriad head cover bolts is fairly critical if you don't want an oily mess. You need to be creative in inventing a few different torque adapters. You will find that you can torque each and every one of the head bolts. Here are just a few of the ones I've come up with over the years: http://i235.photobucket.com/albums/ee201/Digger109/TorqueAdapter-1E.jpg http://i235.photobucket.com/albums/ee201/Digger109/TorqueAdapterE.jpg You'll need to perform a few measurements and apply a little math.....nothing any biker can't handle. |

Title: Re: How much oil should be in the head cap? Post by ero4444 on 12/10/09 at 15:21:45 those arrangements look pretty funny, but actually my physics instinct tells me that torque is the same throughout the rigid assembly. So no math should be necessary, if the stress on the bendy bar makes the pointer indicate 10ft-lbs at the 3/8" square drive, then the torque is also 10ft-lbs at the closed-end-wrench. Which is kind of a cool effect. But I'll have to ponder a while to be sure. Why didn't you mention this 25 years ago right after I took Dynamics class? EDIT: oops - Digger must be right about requiring math. Longer arm, less force required, bar doesn't bend as much. doh |
