Well, actually the carb would fit, its just not an exact replacement and some mods would need to be done. Keep what ya got! |

well, no luck. i bought a new vacuum piston, the piece with the diaphragm, and the problem still persists. I'm confident now that the problem is the float. What are the symptoms of a damaged or out of adjustment float??????? |

A float would either allow too much gas or not enough - it is das boot - I said if it wasn't one then it had to be the other. EZ |

Eureka!!!!!!! Hallelujah!!!!!!! Holy freakin' ****!!!! WOOOOOO HOOOOOOOOOOO!!!!!!!!!! It was...... The SPARK PLUG!!!! I talked to a guy who said it is common after a re-jet that the engine runs richer and the plug can get carbon build up. I put in a NGK plug and my BLAST is a BEAST!!! i can definately tell the upgrades helped. velocity stack, rejet, shim and relocating the breather tube have made my blast quite a fast little scooter!!!! thank you to everyone who has given me input, and remember this in the future if you come across someone with the same symptoms. case closed... |

Woo hoo - lol the trick is - we are not there to check such stuff - and if you where using the Iridium racing plug - the question would never have occurred - each situation is different and you can only offer most likely scenarios - the plug does produce those symptoms if the wire is loose or the plug partially fouled, however, since your plug was fine before, it is a common given that it would be fine afterwards - in this case we of course would be wrong. It is always a good idea - in my book - to check your plug every 3000 miles or so just to make sure everything is fine. Yes those mods really waken the bike up and make it a hoot to ride - stock is nice, but the dark side brings new joy to an already great little bike! Welcome to the Dark side! EZ |

A 170 should be lean - this is strange - ahh - I know - are you running my old style filter or the one I recommend now - also from Outerwears - its custom and costs a bit more, however, it flows twice as much air - and works very well - that is a good question. Issues did appear on the old style standard style - if its white its right - for the color of the filter - they have only ever made it in white - being a custom material - it has only come in white so far - if enough folks order it, then perhaps it could get regulated to regular and then colors - at least I know when its dirty and needs washing;0) - EZ |

The regular is restrictive and will starve you between 3500 rpm and 5000 rpm causing all kinds of weird stuff to happen and usually happens in WOT conditions - not really as noticeable in partial conditions. EZ |

what i dont understand is that all of you say dont touch the float...and be VERY careful not to bother the float and then he said he most def, touched it, bumped it...abused it...atleast a few times..and no one has said what to do in this situation you said yourself that the float could cause it to have too much fuel or too little fuel and obviously he gettin wayyyyyyy to much fuel if he fouling the plug that easy... So...how does he fix the float problem |

there i did the legwork on this one.... 8. Perform float level check as follows: a. Place carburetor on a clean flat surface with the intake manifold side down. See A of Figure 4-20. b. Tilt the carburetor 15° to 20° in a counter-clockwise direction until float comes to rest. See B of Figure 4- 20. NOTE The measurements will be incorrect if the carburetor is tilted less than 15 ° or more than 20 °. c. Using a dial vernier caliper or dial caliper depth gauge, measure the distance from the face of the carburetor flange to the outboard edge of the float. Be careful not to push on float while measuring. d. If the measurement is between 0.413 inch and 0.453 inch (10.49 -11.51 mm), then the float level is within specification. Proceed to step 9. e. If the float level is not within specification, remove the float, and referencing the table below, carefully bend the tab slightly to adjust the float level. For example, to increase the float measurement, bend the tab toward the carburetor body. This will have the affect of decreasing the amount of gas in the float bowl after assembly. f. Install float and check float level again. Repeat procedure as necessary until float level is within specification.

You do the float according to the manual - carb comes off bike - new floats are solid so usually it is only mis adjusted - usually the float tweeks too much gas - as gas pouring out the carb - since that didn't happen - I suspect the other. EZ |

Right on Mp! But if he's using the wrong Outerwear filter it will cause problems. Running without a filter would generally make those problems go away. |

Thank you guys...im sure he will really appreciate this...if its not the filter then it has to be the float.. I dont see how a thin material like the pre filter can stop so much air from going into the carb as to make it not run right and thank you muckerpuck!!!!! |

YEEEEEEEE HAAAAWWWWW!!!!!!! i figured since it was running so rich i would remove the shims. guess what? after an hour long ride last night it runs perfect. not as crisp as it was before, but no more carbon sputtering: the top end is definitely lacking something... i think since i didn't install the 175 jet, plus the more restrictive intake filter, it was running waaay rich. EZ, can you provide me with a link to order the custom cover you are talking of? thanks!!! Gearheaderiko, if i run without a filter, wouldn't that allow debris to be sucked into the carb!!???

Outer Wears Stack filter outerwears.com - the new part number is - "100 - 2651" - you'll have to call them. Try shimming it after the new filter is applied - the result will be better. EZ (Message edited by ezblast on March 28, 2008) |

I accidentally put in the B50s yesterday. Now, I go from full throttle to as slight drop in throttle and get more power. That's with a 175. Do I go 180, or add shims, or what? Spark plug was still very white before I did it. |

48/180 should do it - its working well for my city bike, even on backroads, yes I'd shim - 1 to 2 - I do 2 #6 machined brass washers in both - its still not super rich - just a slight smell with the huff at shut off. Take off on the force is as good as its going to get - will probably cut the can off and add another Suppertrap 4" Disc with 2" inlet - the sound is cool, mucho quieter, and the bottom end will be much better - I'll loose a hp at the top, but it would be worth it for the return of a bottom end - though from 3000 rpm up the acceleration is almost as crisp as my weekend bike - a real testament to the ability and tuning of the Force exhaust - wide open she really booggies - lol EZ (Message edited by ezblast on March 29, 2008) |
