CBR900RR , 94 model, I ride it to work, about 40 mins each way every day . In the last 2-3 months it has overheated & the plugs fouled ( I am assuming ) on 3 occasions. Once was in terrible traffic, but yesterday it did it in really mild traffic. The temp guage is not hitting the red, maybe 3/4 , & then it starts running really rough at low revs in the stop start traffic. After stopping & giving a rest & then riding with no traffic it seems OK . 1 time it was completely screwed & needed the plugs changed , but that was also due to dodgy fuel I believe . Has anyone got any suggestions as to what I can do to avoid this, as it not exactly hot & I am not looking forward to summer if this is what it is like in winter . I don't think this should be happening in mild traffic on a 40 min ride?? Any thoughts appreciated.
