2005 502 Questions
Posted: Sun Dec 09, 2007 8:06 pm
A few questions, first the easier.
1. what is the proper torque for valve cover gaskets? some will say good an tight,,, but i would like to have a proper value whether ft lbs. or inch pounds.
2 chrome was peeling in three locations on my valve covers and i sent them back for warranty and were replaced immediately Rodger Mcclain at Lima Auto Mall AND the Factory gave perfect assistance. Requested new valve cover gaskets and pvc grommets and the replacement valve covers and got them. However,the covers i sent off had hold down tabs formed into the cover itself,,, which i liked. The new set does not. As stated the bike is 2005, does anyone's 2005, 2006 or 2007 502 have these type valve covers with NO hold down tabs molded into the metal of the cover? Is this a cheaper version? or is it an outdated version? or what?
3, now of performance, 5700 miles now, got it when it had 2700 miles, installed the vacuum advance and set timing on 36 degrees with i think it was six turns on the vacuum adjustment allen screw. I performed carb mike's stage two mods with the only omission being being to trim the gasket inside of the accelerator pump hole. Now my issue, most of the time when i whack it from say 40 or 60 mph i will get a good clean crisp whack. Plugs i changed and all the same and they looked good to my comparison of plug reading chart. But once in a while,, when i whack it between those speeds,,, i get a stumble. changed distributor cap and rotor, have gone back to the original plug wires as i was getting a miss out of my $160 ones, was using the borg warner select with brass inserts dist. cap. this time went to a MSD dist cap with brass inserts. Now i have recently read in the manual "
ADDITIONAL TIMING SETTINGS: (WITH VACUUM ADVANCE CONNECTED)
502 engine: TDC at 42 degree at 2400 rpm"
have yellow and silver springs in the dist. when it runs good,,, it runs great,,, but occasionally it stumbles. I whacked it 3 times yesterday,,, no stumble, but the fourth,, got a stumble. I check the dist. cap about once a month for corrosion on the brass tabs and have a little corrosion on the tabs when i check it. Not much, but a little and i replace it. I know i can clean the corrosion,,, but i change it. that tells me arcing during fire and firing when not completely lined up during rotation of rotor to cap and or timing adjustment needed? Cold weather (like we really get it here in south texas) i though it runs better,,, but the weather does NOT seem to make a difference. Runs good and stumbles occasionally in warm or cool weather. Also have a MSD electronic module with rev limiter installed and rev limit set at 5700 rpm. Idles good,,, normal performance good,,,, just an OCCASSIONAL stumble. 100 miles, 5.6 gallons,,, 17.8 MPG plus another 60 miles later so vacuum advance install has helped my mileage. Also installed the quick disconnects for the gas lines from small parts.com. One other tidbit, when going to whack it, my normal method is take off normally accelerating till about 50 mph, speed limit goes 35, 4o, 45, then 5o for about 1/4 to 1/2 mile, then whack it up to 100 and let off. Any help on this issue or experiences will be appreciated.
