Hi guys want to do a full service on my 94 zxr 250 ...just want to know which oil to use and are NGK iridium spark plugs worth putting in thanks
I use Motul 5100 10w40 in the Fizzer. Its not cheap but its not somewhere u should be using something cheap and nasty Just make sure its motorcycle oil and not designed for cars. Iridium vs standard plugs ..... lots of discussion on the interwebs http://www.totalmotorcycle.com/BBS/viewtopic.php?t=24752 The Fizz had a set in it when I bought it but I put in new standards....will buy a new set eventually to see how they go and compare.
I use 10w-40 Shell as thats what my bike shop sells , as for plugs, they are CR9e for standard plugs and CR9EIX for Iridiums, oil is 2l without changing the filter or 2.6litres with a new filter. The filter is HP303 (Hiflow filter)
i just changed the original iridiums in a falcon with190k on it and was still running ok but the tips had burnt off, i use iridiums in my bikes for longevity and buy them from the states off usa ebay for the cost factor. i think iridiums work best on computerized ignition systems.performance wise[fuel economy,power]isee no change.
I recently fitted a set of Iridium plugs into my ST1100 after 20,000Km on standard NGKs and have noticed no difference in power and a minute difference in economy. These should do about 50,000Km before I have to change them again. Bought from ebay UK for the same price delivered as standard plugs in local Honda stealers.
Thanks everyone had a nice surprize to day when i pulled off the carbs for a clean. I thourt firing order was out when i looked at leads thinking engine was a C4 but firering order sugest its between A1 and B2. by the way Chris awsome rightup on carbi cleaning
Rule of thumb, stick with what the manufacturer recommends. The only bike I have owned that used iridium plugs was my CBR1100, they do tend to last longer. I was buying standard plugs for $3.50, a little hard to justify $20.00+ for iridiums. Oil changes every 6000k's so any brand of 10w-40 oil is fine by me.
