plug caps

[davey]

just got back from picking up the new project 250 lc.
when i picked it up the guy said that he was having a problem with the left hand cylinder runing correctly , he told me hed done all the normals and he narrowed it down to the plug caps that were or were not fitted with surpressers, acording to him the new ones all have these yet not the old originals . i never heard of this so maybe somone out there could enlighten me regarding this .
i must add that when i rode it, he had dury rigged the the lines with wire so removing all the plug cap and when i rode it ,it was fine , so i guess do i need original plug caps or was he feeding me a barrel of shit,,,,,,,,,,,,,,thanks the plugs in it are BR8ES

id say put new plug tops on and try this is the cheapest opyion to start with.btw im running br8es's but i think they shud be b8es's

You should have a resistor, either in the caps, or the plugs. The R in BR8ES is a resistor, so you can use plug caps without the 5K resistors in them.

For my money I've found these to be the best caps cgi.ebay.co.uk/NGK-SPARK-PLUG-CAP-RESISTOR-COVER-KTM-CR-YZ-RM-KX-MX-/130501866774?pt=UK_Motorcycle_Parts&hash=item1e62847516

The normal type I've found fall to bits internally due to vibration.
These are resistor caps so you need to run B8ES plugs
