fast by ferracci airbox frame questions
i recently put the ferracci airbox frame in, i had an semi open hacked stock one before, and i noticed
the bike loses power/stumbles/runs rough at about 80mph, as fast as i decided to test at, about 75% of comfortable max. i was pulling about 5k rpm. i notice that at
lower speeds at the same rpm, it did not do this, and with the exception of high speeds, runs better.
now is this from running too lean or turbulance over
the filter from the high speed forward wind pulling air away from the filter or just from the very cold air and moisture (40°) or from the force of air blowing into the filter.
i am running the stock jets and was running a little rich prior.
according to Fast by ferraci i did not need to rejet for the frame.. just wondering. .. is this why the DP performance
kit has the raised edges.. .. the fast by ferracci airbox frame is at filter height offering no air block.
anyone come up with this, or have 2 cents worth.. ..
i also notice it made the bike run hotter, so i assume it is running too lean.
i drove only 7 miles (10 minutes) in 40°F at 30 - 70 and it felt like the bike was running much too hot, i would say by touch at various places, fins, crankcase, heads... about 140 - 180°.. hot to touch, but not too hot to hold your hand on for a duration, hot for winter in sf, near overheating, i am guess-timating the temp, but that seems about right. so i guess i am
taking the thing off 'til i sort it out, the bike feels much hotter than usual for the riding duration and outside temperature.. glad i picked a cold night to freeway test it on. kind of gets me, i asked ferracci if there was anything i needed to do, like jets or mixture and they said "no", given a hot day and a long ride, i could have fried the engine, in particular, the pistons.
anyone know of a good place to take it to get it tuned in SF, CA.
