750 K7 needle position
UKROBK7:
Hi Voxonda, can you tell me where you got the middle position from? My Honda factory manual and the supplement I bought says needle setting F2051E-1 for the K7. The needles in my carbs are F2051E (or F2D51E, can't really tell). The guy in Canada says -1 means top groove, -2 means 2nd from top etc. I was assuming that the factory manual I bought was for the UK but perhaps the settings given are for the States. I have normally set needles to the middle position on my other rebuilds and adjusted after road test but with 4 carbs this time I want to start out right!

Hey Rob,
Correct the -1/-2 is clip positions, but.....................recently rebuiild a set of carb's from a stock K7, first owner. Bike was stationary for a few years. Had to clean them and give them a ultra sonic bath. These needles from a "Dutch" bike were in the middle position. According to this owner bike has never been dissambled. Due to environmental regulations and/or type of gas settings can differ from country to country.
Cheers, Rob
UKROBK7:
Thanks Voxonda. I am tempted to go with the middle clip position. If I decide to keep with the top clip position I will keep an eye on the plug colour. I don't like to run an engine too lean - I've seen a few holed pistons on early British bikes and don't want to see this happen on this engine rebuild!

That is a safe bet! Better than the other way around. She'll love that extra bit of petrol.
