Title: Spark plug caps and ht leads (coils)
Post by: Dave4521 on 27 June 2018, 11:55:15 pm
Hiya
 
I removed one of my spark plug caps (no 4) this evening and obviously pulled too hard on the ht lead itself, as it separated from the cap.  It looked like it had severed apart. Anyhow, I sort of stuck the two parts back together and slid the seal back over it. It seemed to hold together okay.


Tested the bike down the road and no obvious loss of power, so I assume there must be still be a live connection on no4, at least until I next hit a bump in the road  :b


Question:  Will I need to buy an new complete coil/ht lead/cap?  Or are the lead and cap actually meant to be in two parts that stick together easily by hand?  Thanks..

The caps actually screw onto the HT lead. They can be swapped easily.

The spark plug cap has a self tapping screw in it.
The HT lead consists of a small bunch of wires, which over time get pushed into the outer plastic casing of the lead.
If you snip 5-10mm off the ends of each lead you can then carefully screw the cap back in until it stops and feels firm for a fresh connection.
It's quite important that the connection is good and solid otherwise it can cause running issues, especially in bad weather.


Also another option, which a lot of us have done because they are so dirt cheap, is to replace the caps for under a tenner with NGK ones, which work absolutely fine.
Last time i checked original replacements were at least 20 times more expensive.  :eek
