Title: starter gear, automatic decompression ?s Post by dex3703 on 03/30/08 at 09:09:58 Hi, Well now that I've got the valves all adjusted I have a couple questions on the starter gear and 'automatic decompression cable adjustment'. Mainly to see if I got it right because the bike is all put back together now. - When I had the generator cover off, the starter gear (the gear on the shaft of the starter motor) slid off and I didn't see for sure which way it should go back on. On the gear's shaft hole, the gear has a flat side (level with the teeth) and a side with a raised part. The shop manual is useless with no pictures or instructions on orientation for this. I put it back with the raised part out, against the case, as it didn't seem like it would have room to rotate if it went on the other way. Also that way all the teeth meshed with that other gear (the one made of three thin sections that connects to the flywheel). Just asking if I put it on right or if I need to take it off and spin it around (hopefully not). - Automatic decompression adjustment. The shop manual is again useless as the instructions don't actually describe what you're measuring, and the picture is crap. Are you looking for 3-5mm of play at the end of the little arm: 3-5mm of space between the bottom metal piece that doesn't move, and the arm? This is what we did--it needed to be adjusted slightly (if that's what needed adjusting). Any info appreciated. Haven't started the bike yet. THanks, Derek |

Title: Re: starter gear, automatic decompression ?s Post by verslagen1 on 03/30/08 at 09:18:05 Decompression adjustment, I know had the same trouble my self. The measurement should be done on the decomp solenoid. It's on the other side of the frame, big round thing with a rubber cap in the center. Pull the cap off and you'll see a little shaft. that's where the measurement should be made. |

Title: Re: starter gear, automatic decompression ?s Post by Oldfeller on 03/30/08 at 10:14:07 No, results are the same and the TOLERANCE range is huge anyway. You'd have to struggle to get it set outside the tolerance range no matter which end you adjusted it from. Me, I figured that the system can only "stretch" to get looser, it can never get tighter, so I adjusted mine to the 3.5mm minimum number and I bet I never have to mess with it again, ever. Decomp works fine now, but mine doesn't have the huge "CLACK" sound that the rest of you guys have to listen to when you hit your starters. Oldfeller |

Title: Re: starter gear, automatic decompression ?s Post by Reelthing on 03/30/08 at 10:34:39 on the decomp there is a picture in the techsection some place that shows you - just pull the rubber cover off and push it pack with you hand and measure how far out the end shaft is - I'll see if I can find it |

Can you see me scratching my head trying to remember. Mine did the same thing. Plopped on to the workbench and I said DA.M.... Problem is I can't remember if the case cover will cause it to bind if it's in backwards...... Or.....if the case doesn't seat correctly...... Anyway, it will only go on one way ........ |

Title: Re: starter gear, automatic decompression ?s Post by dex3703 on 03/30/08 at 11:04:36 The case will only go on one way? If that's true then I got it on the right way as the case is on and sealed up with no trouble. |

Title: Re: starter gear, automatic decompression ?s Post by dex3703 on 03/30/08 at 15:22:16 Does anybody disagree? Is it ok to start it up? Thanks! |

3.5 mm is way too loose! 0.003" is the smallest... 0.003" * 25.4mm/inch = 0.0762 mm exactly |

Title: Re: starter gear, automatic decompression ?s Post by dex3703 on 03/31/08 at 08:45:29 The shop manual says it should be between 3mm and 5mm. I think we put ours at 4mm, but at the end of the little arm, not on the solenoid. so that's where that loud clack noise comes from when you hit the starter? I'll be happy to have that gone. :) |

Title: Re: starter gear, automatic decompression ?s Post by vroom1776 on 03/31/08 at 10:00:56 no no no... it's 0.08 mm to 0.13 mm, OR 0.003" to 0.006" also, see here (http://suzukisavage.com/cgi-bin/YaBB.pl?board=tech;action=display;num=1151938664) |

Title: Re: starter gear, automatic decompression ?s Post by dex3703 on 03/31/08 at 10:20:02 Thanks for that link! I'll be sure to check that I was on the right stroke. I just followed the shop manual and turned it to the mark--don't know which part of the stroke it's on. The automatic decompression is 3-5mm. The valves are .08 and .13mm (I think). I was going off the shop manual measurements. Also, what size socket do you use for the spark plug? My standard sized spark plug socket didn't fit, and I couldn't find a long metric socket that would fit either. Thanks, Derek |

Title: Re: starter gear, automatic decompression ?s Post by vroom1776 on 03/31/08 at 11:35:27 there are only 2 standard sizes for spark plugs. you have the one, which fits a V* (haha). get the other one. they are SAE (english) sizes, not metric. |

Now I'm going to have to check when I get home.... I thought they were a metric size....... As for the gear, take the inspection plug off the flywheel/rotor cover and see if you can turn the engine. Also, take the spark plug out to make it easier to turn. |

Title: Re: starter gear, automatic decompression ?s Post by vroom1776 on 03/31/08 at 13:48:45 my bad... 18 mm & 13/16 are the two sizes I have. |

Title: Re: starter gear, automatic decompression ?s Post by dex3703 on 03/31/08 at 13:56:33 The engine does turn. We put the cover back on (because I had my wife to help at the time) to make things neat and basically get back to where I hsould have been had I not broken the little inspection cover. It was after we had the cover on that I used the socket wrench to turn the crankshaft bolt to the timing mark. Aside from pumping resistance (spark plug not removed) it turned fine. So I passed the test for having the starter gear on the right way? :) I tried a couple metric deep sockets to get the plug off, and couldn't find one that fit. My small size spark plug socket didn't work either, and I don't have a big size any more, so I couldn't try it. Thanks, Derek |

Title: Re: starter gear, automatic decompression ?s Post by dex3703 on 03/31/08 at 14:15:19 Great, that's a relief--biggest thing I was worried about. Now though after reading the valve adjusting writeup, I don't know which part of the stroke I was on! So will check that next weekend. Pretty soon I'll have this down pat! Thanks, Derek |

Title: Re: starter gear, automatic decompression ?s Post by vroom1776 on 03/31/08 at 14:59:46 well, if you adjusted it to the correct specs, but on the wrong stroke... well, it sounds like you have a wrench inside the combustion chamber. I did that my first time... |

Yep, 18 mm deep well. The local Auto-Zone has them at an ok price. |
