Re: Spark plugs recommendation for easier starting
I use Bosh platinum plugs---STAY away from champions as they do come in the correct heat-ranges--but are a junk-plug!---just take a used autolite or AC plug-----smash-em apart along with a champion & the reason is instantly visual!-- Champs have areal almost paper of an insulator!--then look at the others----LOTS of meat!---I have been messing with these along time, you can accidently drop a champion-so you recheck the gap & in iy goes--only to end-up with a miss!---IT WONT happen to the others I mentioned--(I TRIED IT). NOW put the champs in the envirement of a rigid bike air-cooled--yes the temps are a little hot!---They do not hold up!--THIS is a old thread but I just read-it! & have to tell everybody, that dont know!-In my shop a guy would bring his bike in for a tune-up & pre-buy all the stuff-yes champ. plugs! Put everything together, never dropped a plug---also I told him dont use these before they were installed! We go to fire-up & plop,plop,bang,plop,plop,bang---one cyl. not firing!--I felt which one was cold,& put his old plug in & restarted the bike & it ran with no troubles!. So we pulled the other & put the old AC back in. Who knows it could have been mishandled & dropped while being put on a shelf!-Just MY 2-cents on the suject.(Good-Rides to all!).----58flh

58flh, what do you gap those Bosch plugs at? On my '56flh I've been running Champions at .25 with points gapped at .22 and now you have me curious, since I tend to drop things a little too often
Thanks!
Johnny

JOHNNYBADBRAINS----Sorry for the long-time to respond to your ?--I gap mine as much as I can get away with!--Right now the cond. of my plugs/there tired so im at .028/when I change to new ones it will be .035--(remember platinum is a real good conductor of electricity! Also the wider the gap the more power you make for the simple reason of the longer FLAMEFRONT!--IT burns-up the air/fuel mix way better! oh yea & dont use (radio-suppresion wires) if running points! THEY are great for electronic ig. but crap for points! Again the bike will run & run good---but youll gain a better spark using the non-suppresion wires!.& that = better flamefront once again! & thats what you want!---Its hard to find non-supresion wires/ what I did was buy a set of MSD,non-radio suppresions for$86 for a 6cyl. motor ,Then I made-up wires for myself & a few buddies,its expensive for sure but you get a few guys to pitch in the kitty & off you go!.---(GOOD-LUCK)----RICHIE-(58flh) I forgot to tell you something everyone should do,but dont!--Index your plugs with a sharpie.Just make a straight line down the plug where the gap is. Then when putting them in with new crush-washers you set the spark-up to fire dead center everytime.once you go past ,its over for that cyl. anyway,could work on the rear jug? so do it slowly.This also is free-power to be gained/& good flametravel!----RICHIE(58flh)---Little things like this no matter how small all add-up at the track!--these were my proving grounds growing-up as a kid with dad& his buddies racing that old Iron!& it still is the proving grounds for tracks around the USA!.

Re: Spark plugs recommendation for easier starting
HEY GUYS!---AGAIN I have found out which Bosch Plat+4 work in PANS!---HOW I did it!---I have a biz. account at a Autozone!--The guys know me & He let me open all the +4 boxes till I found the correct thread & Depth of plug!--NOW these plugs are 5/8 size plugwrench!,Also they are the tapered style for modern cars that seal to the head!--(I chucked-up the plugs in a lathe ,faced off .010 to .015--I liked the .015 better because it gave me more meat on the compresion washers!)--The nice part is you dont have to gap or index these plugs!-As every 90 degrees theres a multitude of sparks happening!.--The pros.----Better throttle response & I had great response as it was & It IMPROVED!, Gas milage went up to 3.8--just call it 4 miles per/gallon!--Solo rider, I ride 2-up 80% of the time & have not yet done the #s!--I suppose it would be half that ,But you dont know till you do it!. Motor temperature --SAME AS ALWAYS!--I expected a rise but no its the same!---I tried putting 1-in out of the box without cutting it down on the taper--& it works!,no leaks!--(BUT THE ADDED seat for the washer by removing .015 is better!--When you dont do this simple step the crushwashers ride on that taper & can ruin your top plug thread in the HEAD!--So I recommend the .015 face-off of taper!. Finally The PLUG # you want is --(BOSCH PLATINUM+4--4449,HGR,9,BQP)--& KICK STARTING Woke me up!--My bike fires in 1-hotkick cold or hot Just ALOT LESS EFFORT in the kick on the comp. stroke!--I just relax my leg & shes on!--(NICE-PLUGS)-I like em & would recomend them!---My next one is going to be the IRIDIUM-PLUG,-(the word is according to bosch is that as soon as the current hits the plugs they are instantly at operating temperature!)--WE SHALL SEE!---I dont know much about iridium but ill read-up on it & see if its true or not!---GOOD-RIDES to ALL-----RICHIE
