got my 2003 vn800 15k on the clock V&H cruizers standard air box and filter 135 main /48 pilot jet A/F mix 4 turns out running rich coughing and sneezing
opened her up with 170 main and 52 pilot ran great sounded awesome while idling and still sneezing did top slide carby mod throttle smoother but still coughs and sneezes when riding checked plugs still very rich and wet not fuel fouled plugs
went to 140 main and 48 pilot jets and 1 3/4 turns out plus extra 1/2 turn on the A/F mix as per Russian wolf and a .018 brass washer shim on standard needle
took her for a spin on the highway blow out the cobwebs and get a spark plug reading 80 - 100km zones sweet great power and response all through the range gagged along the way gave it a flip of the throttle and she was good then again down the road she stalled I stopped and she restarted the 30 minuted into my ride she stalled and stopped I let her cool for a few minutes and she started not more than 500m down the road she stalled and was not able to restart weak battery
friend came and we replaced with fully charged battery swapped fouled plug in the rear with the clean plug from the front drained high octane fuel and replaced with 91 octane fuel checked spark against bolt weak orange spark on both plugs reconnected plugs and she kicked over rode home cautiously no heavy throttle she rode home through 60, 80 and 100k zones sweet and smooth no missing and stalling
got home checked plugs front fouled plug now much cleaner with grey tip and charcoal ring and clean porcelain the rear plug now looked the same
checked ignition coils front and rear primary readings 2.9 ohms - secondary readings front w/o lead 13.62 ohms - with lead 18.49 - front plug lead only no reading
rear coil w/o lead 14.04 ohms - with lead 18.86 ohms - plug lead only 4.83 ohms
front plug lead not showing reading tried rear plug lead on front coil 18.49 ohms - plug lead defective will swap
main reading on ignition coils firm just reading after decimal point flutters on both coils
tried applying heat with heat gun to ignition coils readings went from 13.79 - 14/15.00 ohms fluttering up and down
checked pick up coil through connector .4 0hms ( is this 400 ohms? or is it stator coil resistance which should be between .3-.5 ohms) (standard reading for pick up coil should be 380 ~ 570 ohms) i am testing through connectors at the end of the pick up coil added heat to pick up with heat gun and reading jumped up to .5 ohms
checked rectifier reads 872 one way and zero the other way on multi meter - all good
want to check ic igniter but paranoid as manual says not to use any other multi meter other than kawasaki one might damage unit
put new spark plug in leads checked for spark still weak and orange
battery fully charged - 12.59 v ( should be 12.6 or more)
coils are $230 dollars a piece from japan w/o plug leads
prior to taking her on the highway I rode around the neighborhood - again great while idling but after riding for a while 15 minutes started to feel like she was dragging and needed to keep revs up so she would not gag and stall and just got home - so i thought may be because i have just been starting and idling the bike that she needed a clean out so i thought i would hit the highway
mechanic said check earth wire connections found wiring diagram can see earth connections to battery, coils, fan, starter etc but no earth connection to frame of bike ?
any help would be appreciated
