Had a bit of a worry today, went to work on the bike at an ungodly hour this morning (riding to work ALWAYS cheers me up!) - but coming home, about halfway, it suddenly lost about 50% power! Needless to say I was more than a little concerned, being that the BIG RIDE is less than a week away! So, I get home nice and slowly, the bike missing and coughing and sounding like crap, whip out a spray bottle with water in it (for just this purpose as a matter of fact), and quickly check the heat on the exhaust manifold (hot metal sizzles the water off really quick, cold metal not so much), to find that the 4th cylinder was A LOT cooler than the rest... Okay, methinks, I've only just cleaned, balanced and tuned the carbs the other week, so I'm hoping like mad it could only be one thing... Check the fuel line just to be sure, its okay. It's 3:30 in the afternoon already, so the shops (Repco, Supercheap etc) will only be open for another hour and a half at most, so I make a couple of quick phone calls to find a set of new spark-plugs - without even testing the old ones properly (I had taken them out and two looked pretty brown around the base of the white bit) which haven't been replaced in almost 18 months! (Bike was off the road for the better part of a year, I was getting around to it okay!)
Borrow the flatties car (Thank-you Thank-you Thank-you!) to speed up to Huntly Repco(the only place anywhere near with my specific spark plug) to make a $76 purchase (PLEASE DEAR GOD LET THE PROBLEM BE THE SPARK-PLUGS!!!)
Back home again, fit the new 'plugs in, fit the radiator back to it's mounting, one more quick prayer, hit the alarm button then turn key and hit the starter button...............
...and VIOLA! Hey presto, the motor fires into life, no coughing, no misfire, no nothing - infact, after an hour finding the new spark-plugs the temp needle was down to cold again, but as soon as it came to life it settled down to a nice steady even idle! That doesn't happen very often to say the least!
Suffice to say I'm smiling at this point! Yay I should be a master bike mechanic!!!
FYI: NGK CR9EH-9's (specified spark-plug for Honda CBR250's - all models) are $19.20 each at Repco, now that we are into summer again (LOTS of riding ahead) I think everyone should go out and invest some $$$ into their trusty steeds... Spark plugs are wonderful things, but miserable when they fail! Go on, DO IT!
1990 CBR250RR - fully rebuilt and awesome!
1999 CBR900RR - a work in progress...
