1st track day in the bag with the new 914, no decent pics yet (there was a photog in attendants, but haven’t seen his pics yet). Car rand great and although running with much newer machinery she was holding her own once her driver brushed off the cobwebs... (IMG:style_emoticons/default/driving.gif)
Since this was essentially her first shakedown I found a number of little things I need to address, one in particular I’m questioning: After a few laps I noticed - mainly on a flat sweeper turn, when entering hard on brakes and trailing off while turning in I’d get a soft groan from my outside wheel (drivers in this case). I’m thinking wheel bearing? I’ve never had one go bad on the front spindle before, so I’ve never heard or felt the slight vibration before. Never really occurred on any other turns.... thoughts?  |

@stownsen914 I never answered your question about the carb specs. Sadly I'm a noob as it relates to carbs, which is why I'm so thrown by this. When I did the carb rebuild I was able to figure out the following, but as i go down with the main jet and idle jets, my gut is telling me that everything else is too big...
Weber 46 IDA 3C Idle jet: 50 Main jet: 140 Emulsion Tubes: F7 Air Correction: 170 Choke: 42 Air filters are K&Ns with a flat rain shield type top. Exhaust are equal length 6 headers at 1.625 and a monte 2 in 2 out muffler. |

That caused what I think was significant shrouding of the air flow.

Hmmm that did cross my mind, but I see this setup consistently, so I dismissed it...could be why she seems out of breath on the top end... |
