Title: Re: Carb jet replacement...Worked like a charm Post by J C Stokes on 11/06/12 at 19:31:18 Silly question, did someone post a thread about Japanese and US phillips type screws needing different screwdrivers? |

Title: Re: Carb jet replacement...Worked like a charm Post by braveteacher on 11/06/12 at 19:39:27 I don't know...but I could not get them out for nothing and my bike is a 2011...I wish I would have thought to use the cut wheel to make into a flat before I spent so much time drilling and extracting and spending $4 at ace for an extractor that broke...But hey I got it...so lesson learned for everyone out there...use a cut wheel on your grinder...cut into a flat head and go to ace and purchase 4 new bolts with allen heads... |

Title: Re: Carb jet replacement...Worked like a charm Post by rfw2003 on 11/06/12 at 20:39:01 It's been mentioned a few times here and there but not in a thread by itself. The screws are JIS standard unlike most of the Phillips screws we are used to here in the states. I have found if you take a cheap #2 Phillips screw driver and grind the end down some to make it less pointy on the end it fits much better. Another option if your an avid firearms person is to use a good quality gun tool kit that has a wide variety of screw driver bits and you will find one that fits them perfectly. R.F. |

Title: Re: Carb jet replacement...Worked like a charm Post by Serowbot on 11/06/12 at 20:54:06 Those two tiny screws down in the slide tube... are the most terrifying screws on the bike... Booger those and yer' toast... ;D... Now, get the dog to clean up that boo-boo... :-?... |

Title: Re: Carb jet replacement...Worked like a charm Post by 07s40scotty on 11/06/12 at 21:09:21 Great pics. Glad your re-jet worked. I have a set of screw drivers that are made for japenese phillips heads- they came from my dads collection so I don't know where he got them from tho. |

Title: Re: Carb jet replacement...Worked like a charm Post by HondaLavis on 11/06/12 at 21:38:08 You can buy JIS screw drivers off of amazon. Not sure if they would have helped for the screws on the top of the carb; they are WAY soft. I had to cut slots in mine, too. Those were also replaced with allen screws. |

Title: Re: Carb jet replacement...Worked like a charm Post by justin_o_guy2 on 11/06/12 at 22:37:50 Ive had real good results with grinding the tip of a #2 Phillips. An impact with a screwdriver head is a dandy item. Just turn the air control valve down, |

Title: Re: Carb jet replacement...Worked like a charm Post by misterbbq on 11/07/12 at 03:40:06 awesome pics!!! i rejetted mine while it was on the bike still. went with 150 / 52.5 (stock). dyna muffler. stock air filter. i also shaved my white spacer down roughly 1/3rd with a grinder using some pliers as a guide marker (stop grinding when it hits the pliers!). i still get some backfire and shift pops, but it seems to be a lot less. i have MUCH better throttle response now though! |

Title: Re: Carb jet replacement...Worked like a charm Post by Gyrobob on 11/07/12 at 03:53:38 A technique taught to me by an old A & P is to use a punch for little screws that are likely to be stuck in place and have phillips or JIS heads wanting to be stripped. Use a flat face punch or drift to tap the screw head laterally back and forth until you can see it move just a tiny bit. Once you do that, you have broken most of the bond the screw has to its surroundings. Go easy. Once I learned this trick I never ruined another carb screw. In the pics below I was using a small hammer to lightly tap the head of the screw sideways from one side and then the other using that flat face punch. These particular screws took maybe 10-15 taps before they started to move. The lateral movement will be only a few hundredths of an inch,.. just barely perceptible. http://i258.photobucket.com/albums/hh253/Gyrobob_theOriginal/Motorcycle/RYCA%20CS-1%20LS650%20S40%20Savage/LS650carb9Jun78Medium.jpg http://i258.photobucket.com/albums/hh253/Gyrobob_theOriginal/Motorcycle/RYCA%20CS-1%20LS650%20S40%20Savage/LS650carb9Jun79Medium.jpg |

Title: Re: Carb jet replacement...Worked like a charm Post by wambr on 11/07/12 at 09:15:14 excellent work! cool picture! but before you make the cuts the Phillips screws for a regular screwdriver, we could try to apply bat for Phillips screws and gently shake through the not very heavy hammer on a bit . I have on my savage 95 happened. |
