For your information, Following the installation of new stock spark plugs according to specifications, the problem of overheating of the exhaust has returned. Having mechanical limitations, my local dealer Yamaha will proceed to a tune-up in order to find the source of the problem and to return to its normal functioning soon. You will be informed of the continuation and cause. Thanks for all information and research

After this recent experience with iridium sparks plug specified, order news standard spark plug to receive and will say if all is ok. I just hope no trouble with the CP3 engine after this experience of overheating pipes. I changed standard spark plug for iridium because my VFR800A 2008 had stock iridium spark plug to change every 50 000km, and to extend the maintenance ! Modifications recently: air filter K&N, Motul oil syntec, Michelin PR4, belly pan Ermax EVO and Ermax touring screen. Thanks for all informations and Happy new year 2017
