Does this spark look weak?

Hey guys need your opinion on whether or not this spark looks to weak? see video

Also I replaced the spark plug wire with 7mm copper core wire and kept the same caps, don't know if I have the 5ohm caps or not? I order new ones 5ohm from Mikes because I read on the forum that if you have a TCI system you should use them to protect something...... does that sound about right?

Also one more noob question but what does TCI stand for?

Are you running a resistor plug? If so you should use a non-resistor cap. Make sure you have a fully charged battery. The spark plugs look a bit fouled may want to replace them or clean them. The spark should be a bright blue. I find the ngk iridium (bpr7eix) with a non-resistor cap works very well. TCI transistor controlled ignition.

Hey Chris could you explain what u mean by non resistor caps?

http://www.ebay.com/itm/PAIR-OF-NGK...torcycle_Parts_13&hash=item51c6c25cf2&vxp=mtr Resistor or suppression plug cap where designed to reduce radio interference back in the day. A non-resistor has no resistor in the cap. The stock sohc xs400 came with a non-resistor plug and a 7-9k ohm resistor cap. Going to a iridium plug with a 5k ohms of resistance in it already and a non-resistor cap take a bit of resistance out of the system. The iridium plugs make a better spark and holds up much better than a standard copper plug. http://www.mikesxs.net/product/50-5944.html If you buy an iridium plug get them at your local auot parts store as they will be much cheaper than mikes.

Looks like ill try and return the caps I got from mikes, do those NGK Iridium Spark Plug BPR-7EIX have a screw off top? I ran into the problem of them not fitting into the caps? Or will they fit into the ngk caps?

They have screw off tops.
