Spark Plugs

Hey does anyone know anything of the new Pulstar Plugs for the Boulevard C 90 T I hear amazing things but just heard of a story where they shorted out the electrical system. They claim 15 % more torgue and huge gains in fuel mieage. Would love ti hear form anyone who has tried them. Thanks everyone.  

The idea that the spark plugs can short out the electrical system sounds just as bogus as the claims of 15% increased torque and huge gains in mpg.

The worst the spark plugs could do is damage your spark coils, and that would require replacing the spark wires with non-resistive wires also. Simply replacing resistive spark plugs with non-resistive spark plugs, is unlikely to do anything other than generate a little more interference on nearby AM radios.

To get those kind of increases in power and mpg, requires that you are already running the wrong spark plugs and they are routinely fouling from all the unburnt fuel. If you're not fouling your plugs, new plugs won't increase your power or mpg measurably.

Hey thanks for your answer on this The technology on the new PULSTAR plugs seems solid. I have been getting lots of new backfires and seems to be lacking a bit of power and thought perhaps this would help. Also just found out the Air cleaner has no inlet for air as it is built under the false tank and is almost completely incased with just a very very slight area for air to come back in under the seat and around. Sort of a poor design for allowing the engine to take in air. It is a KnN filter but still no way for the air to get in.  

The restrictive air system is normal for modern bikes. That's why replacing the exhaust only makes a bike louder these days, when it used to also make the bike run stronger. Simply replacing the filter, without opening up the restrictive airbox, won't do anything significant for either performance or efficiency. That's why there are so many oddball named airbox mods on the forums (grampsizing, hypercharging...etc). All of them have one thing in common, they let more air into the engine. Of course, the low profile & overlapping cams that do so much to make the engine strong at low RPM also restrict air flow at higher RPM, eliminating the possibility of any significant power band, so airbox mods really can't accomplish all that much either.

If your backfiring is just when you are riding along and you back the throttle off all the way, letting the engine slow the bike, then you're getting a little gum buildup in the pilot jet. The easiest fix is to just back out the pilot jet about 1/8 turn. That will enrichen the idle mixture just enough to stop the backfires, without fouling your plugs during idling. If you have to back the jet out more than 1/8 turn to stop the backfiring, it's worse than you think and you should dissasemble the carb and clean the jets.

Wow thanks so much I will look into it. I now have a new problem so that may be the easy part. Getting a heavy plastic burning smell so gonna need to rip her apart and find that. Thanks for your time on my questions.  

I am totally agree with slowpoke, thanks for sharing a nice information on spark plugs, it is really great information and also helpful for the other riders and it is easy to understand, I like it very much, thanks for the beautiful information.
