Knight_Rider Posted January 7, 2007 Report Posted January 7, 2007 hey guys ive got a 99 shee with fmf gold series pipes standard compression pro design intake boysen reeds no lid on airbox 35mm keihn carbs with 155 main jets. i ride at sea level bike goes awsome but lacks down low a bit anyone got any ideas r the carbs to big. its got wiesco 64.75mm pro lights in it cheers Quote
dajogejr Posted January 7, 2007 Report Posted January 7, 2007 Those carbs are too big for stock porting. You'd almost be better off selling one of them, and getting a 1 into 2 carb setup using the single 35. On stock porting, in my opinion, anything bigger than a 28mm is too big. Quote

I think he is right on but if you plan to get porting in the future the I woul keep those carbs but if porting is not in the nere future then I would get smaller carbs IMO Quote
NYUK Posted January 7, 2007 Report Posted January 7, 2007 bigger is not always better when it comes to carbs. the downside to 35mm and up carbs even with portwork is you lose bottom. nothing a little fancy clutchwork won t solve. Quote
Knight_Rider Posted January 7, 2007 Author Report Posted January 7, 2007 hey sorry i forgot to mention it has been ported just a mild port nothing to big. It seems to be running good i did a plug chop and they came out a dark tan colour prob slightly rich more than lean, just wanted other peoples opinions cause i thought 35mm carbs would be to big, the bike came with them when i brought it Quote
jbooker82 Posted January 9, 2007 Report Posted January 9, 2007 What needle do you have in the carbs? Quote
Knight_Rider Posted January 12, 2007 Author Report Posted January 12, 2007 as far as i know its the standard needle that came with the carbs they are KEIHN 35mm flatside carbs Quote
yamaha04 Posted January 13, 2007 Report Posted January 13, 2007 Whoo did your porting what style of proting was it. i had a buddy pay $400 to get his bike ported from a local guy and he said it was a good all around port. LOL turned out he barly touched at thing when we compared he port to my stock cylinders. Not saying you bike isnt ported but you may want to look into that before you stick with your 35mm Quote
