Title: HELP!! VALVE ADJUSTMENT Post by Hercules on 01/03/09 at 09:26:29 One of the problems I have is a loud metallic noise from the valves, I tried to adjust the valves but found it almost impossible to figure out where the exact top position of the piston is? No matter how many times I tried I either got no compression or compression with loud valve noise?? Please if anyone knows how to get the piston in exact position to adjust the valves or why I cant get them right let me know. Also could the valve rocker be hitting the decompression shaft if the adjustment is off? Thanks Hercules |

Title: Re: HELP!! VALVE ADJUSTMENT Post by Charon on 01/12/09 at 07:08:23 Be even more thankful it has screw and locknut adjusters, so you don't have to remove the cam or cams and replace shims. |

Title: Re: HELP!! VALVE ADJUSTMENT Post by MMRanch on 01/12/09 at 11:00:16 Hercules On the left (down)side of the engine they is round plate about the size of a half/dollar , put a large washer in the slot , a screw drive in the washer hole and unscrue it (right hand thread). I think it's a 17mm socket turn it counter clockwise till the marks line up, while watching the INTAKE valves. The first TDC after the intakes close is the one you want. lossen all four lock nuts on valve adjustment. THROW AWAY YOUR FEELER GUAGE, Now finger run the aduster down till it touches the valve. Loosen up about a 1/8 to 1/4 turn and while holding the adjuster in place with a screw drive tighten the lock nut. If you still have a LOT OF ENGINE NOISE !!!! Your cam chain adjuster is about to fall out and couse SERIOUS damage. Some where on this site is a picture of a modified adjuster plundger, I did the same to mine and now have no noise valve or chain. Also the SPRING that drives the plundger doesn need to be one/half that strong, (doint cut it) replace it with one about 1/2 the wire size. (Tractor Supply-any HardWare Store) Let us know how you come out. I'm not saying the Suzuki engineers are NIT WHITS but the're not that hard to out do. I have over 30,000 miles on mine and would not trade it for any other modle curently being produced from anybody. |

About the washer, never found one that was stiff enough to twist out a stuck timing plug. Use an old front brake pad. The end should fit right in there. And I'd to know more about what size spring you used? wire diameter, number of coils, etc. |

Title: Re: HELP!! VALVE ADJUSTMENT Post by justin_o_guy2 on 01/12/09 at 20:59:26 lossen all four lock nuts on valve adjustment. THROW AWAY YOUR FEELER GUAGE, Ummmm, No.. First, before you loosen anything, check the clearances. If the feeler wont go in, make sure you really are on TDC compression. Then, using the feeler gauge, set the adjuster snug on the the smallest one called for. While its still in there, using a 90 degree flatblade to hold the adjuster while you snug up the jam nut, snug 'er up. Check the feeler now & see how hard it is to drag back & forth between the adjuster & valve tip.It should drag out & slide in w/o bending it, but if its a bit "stiff" to move, thats okay. Once you pull it out, see if itll go back in. If so, its good. If you mess with the adjuster while the jam nut is loose, you'll see that the threads are kinda sloppy. Mine are anyway. when the jam nut is tightened, it will open the adjustment very slightly, as the jam Lifts the adjuster up into the threads. |

Title: Re: HELP!! VALVE ADJUSTMENT Post by MMRanch on 01/13/09 at 15:00:00 VERSLAGEN 1 I just got one from the " extra spring bucket " that looked about right. Mine used to make a lot of noise in the head, till I quit fighting the feeler guage and trusted my fingers, I just couldn't seem to get the guage to go in there with the motor still in the frame.??? |

Title: Re: HELP!! VALVE ADJUSTMENT Post by justin_o_guy2 on 01/13/09 at 22:22:09 I take the individual feeler out of the group, bend it 90* in 2 places, kinda a Z shape, break one end off & bend the rounded end like a ski tip. Basically, its my gauge, I have aplace I need for it go, so, I bend it & shorten it to fit the job. |

Not everyone has edgemacated fingers. But will have to admit, they were telling me they knew what to do last time I did it. I just told them to use the gage and shut up. As JOG2 said, having those locknuts loose will change the adjustment when tightened down. So it's always important to recheck your adjustment when it's all locked down. |

You did not, been using this methode for, say 45 years. Do one adjuster with the feelergauge, measure the difference when tightened and do the remainder by feel. |
