Started out a fine day. Kids gone off, ole lady gone for the day. A fine day for a ride with my honda buddy. Before I went over to his house I shot down the road to warm her up a bit. Been running great lately. But not today. Started breaking up at about 5000 rpm's. Back home I go. The weather's gotten hot and humid here so I thought maybe a bit to rich for the summer heat. Rejecting I go. Down ten points. Off for another test ride,its worse. Rejetting I go back up to 160's. Another test ride, same thing. Well it was running fine the day before and all I did was fill with gas, hum. Drain fuel tank check filters, remove and clean petcock. Fill with gas and off I go. Same thing. The last mod I did was the tbs needles so out they come. Well the miss at 5000 was gone but the temp had droped by the time I got to that so I dont know. Started with 155's K&N's, tbs needles no shims. Now im at 160 mains stock needles no shims, and uni pod filters. It sure is frustrating sometimes. Guess i'll have to wait till tommorrow for the heat to rise again to actuall tell if I accomplished anything today. And it started off as such a wonderful day for a ride.
