Title: Cleaning spark plug cavity? Post by Rylee on 04/14/15 at 15:42:42 Sorry for the thread topic couldn't think of it's exact term. Since there's no cap on it anymore it's really dirty inside the cavity where the spark plug is. How do I go about cleaning that area out without damaging anything or getting sediment inside where it doesn't belong. I noticed today some water must of got in there and the gunk has leaked out of the fins in the front portion below the decomp lever. It's a mess in there and I'd like to get it right. |

I may very well have "over filled" it and I wonder if it's possible that it's leaking up there because of too much oil. It's always been dirty in there but after riding to work today it's the 1st time I've noticed it being wet. |

Title: Re: Cleaning spark plug cavity? Post by Art Webb on 04/14/15 at 16:34:42 I blew mine out with a compressor, but it wasn't wet if you think it's oil, blast it out with Brake Parts Cleaner, it'll flush the oil, if that's what is is, and evaporate quickly leaving no residue |

Title: Re: Cleaning spark plug cavity? Post by Art Webb on 04/14/15 at 16:36:40 BTW, did you just not bother putting the nut back on where the upside down bolt goes through? I always hears you were supposed to stick some washers on that and re-tighten the nut, within reason |

Title: Re: Cleaning spark plug cavity? Post by Rylee on 04/14/15 at 19:20:54 @Art Webb I wondered the same thing about that reversed bolt. That's how it was when I bought the bike. I watched the RYCA videos on both cafe and bobber builds and they just cut the bolt and did nothing more. I'm gonna try some parts cleaner and see if that works. Just wanted to know if a little water in there to wash it out can cause damage. Like is there anywhere it can go other than the spark plug hole that would do harm. |

Title: Re: Cleaning spark plug cavity? Post by Art Webb on 04/14/15 at 20:26:11 I doubt water would hurt anything, but IMO I think the brake cleaner is far superior at getting gunk out If RYCA cuts the bolt off it must not seal anything, maybe I'lll back off the nut some, to be honest i think I may have tightened it more than I should have do you by chance remember which of the vids deals with the bolt? |

Title: Re: Cleaning spark plug cavity? Post by Rylee on 04/14/15 at 21:04:01 The CS 1 video part 2 and the RR Bobber video part 2 as well. It's about half way IIRC when they talk about the decomp mod. |

Art if you pull up the CS 1 tear down video and fast forward to about 8 minutes it shows the cover removal and he talks about cutting the bolt. I had to go back and check. I watched all of these originally when I was trying to figure out how to install the thumb decomp lever since the bike didn't have it on when I got it. |

Title: Re: Cleaning spark plug cavity? Post by Dave on 04/15/15 at 03:53:37 The long bolt does hold down a corner of the head cap, and some of us believe that is should be tightened down...even when the chrome head cap cover is removed. This is not the most elegant solution - but it worked for me. This is a piece of aluminum tubing with a nut....some folks have just used stacked up washers. http://i46.tinypic.com/2mex3lt.jpg |

Title: Re: Cleaning spark plug cavity? Post by Rylee on 04/15/15 at 08:21:20 @dave Doesn't this bolt right above and behind the decomp lever do the same? |

Title: Re: Cleaning spark plug cavity? Post by Dave on 04/15/15 at 09:18:35 See the lower left hole in this photo? That is the sealing surface you are not pulling down tight if you leave that left front bolt without a nut on top. Wonder where your oil leak is coming from? (I think it should be tightened....you can leave the nut off if you want on your bike....I put a spacer and nut on it). http://suzukisavage.com/images/uploaded/headsealplug-041.jpg |

Title: Re: Cleaning spark plug cavity? Post by Rylee on 04/15/15 at 10:47:51 @Dave Now that I see the surface it makes sense. Wonder why RYCA would say in a video it not important if it's actually a corner section of the mating surface that's there for a reason. Now I've just gotta figure out how to get a bolt back in there without removing the entire top. Does that cone off without pulling the engine? |

Title: Re: Cleaning spark plug cavity? Post by Art Webb on 04/15/15 at 10:58:43 I used stacked washers, guess I'll leave em on still probably need to back off a bit, it was hard ton judge how tight it was with the washers shifting, but I probably put it on too tight |

Title: Re: Cleaning spark plug cavity? Post by Dave on 04/15/15 at 12:19:56 Getting a shorter bolt in there is easy-peasy. Get a piece of threaded rod....metric or US in the size that fits. Drop it down in the place it needs to go...and mark it length so you can get a washer and nut on top....an acorn nut looks best. Then cut the threaded rod to length. Put threadlocker on the end of the threaded rod, and then using an open end wrench or needle nose pliers push the nut between the fins at the front of the engine, and then get the nut threaded on. Leave it alone overnight and let the threadlocker set. Then put the washer and nut on the top of the stud....and snug it down. Done! (As an alternate you can try and find a bolt just the right length, and then try and hold a nut in place in the bottom while you thread the bolt down from the top - but it takes a bit more skill and luck). |

Title: Re: Cleaning spark plug cavity? Post by Rylee on 04/15/15 at 14:39:32 @Dave I'm sure I can figure out how to get a bolt in there the task is going to be getting the left over bolt out without removing the head cap. |

Oh...I didn't know it was still in there. Spacers and a nut is the easiest short term fix. |

Title: Re: Cleaning spark plug cavity? Post by Rylee on 04/15/15 at 21:00:01 @Dave Ya that's not possible the PO cut the excess bolt off so there's no threaded area to work with. Gonna have to figure out how to cut it below the fin and remove it in pieces. |

Title: Re: Cleaning spark plug cavity? Post by wakosama on 04/16/15 at 07:41:07 Is there a way to remove a section of the cylinder fins to open up the front of the cavity so we can brush stuff out without damaging the engine? Can't tell from pictures and far away from bike to go look. just asking. and... I saw something in the tech section about how to cut off the long bolt and replacing it with one down from the top to a nut. somewhere. |

someone figured out a way to do it, don't recall what he used though |

Title: Re: Cleaning spark plug cavity? Post by Rylee on 04/16/15 at 21:54:04 @Art I have one of those info-mercial triangle blade sander/saw deals that I think will get in there and cut the bolt between the fins. I just do t wanna damage the fin in an attempt to not remove the head cap. If I can't do it without damage I'll take it off. I just got a full gasket kit so I have the replacement gasket for it. |

Title: Re: Cleaning spark plug cavity? Post by justin_o_guy2 on 04/16/15 at 22:16:13 There is no gasket there. |
