I recently buy used CBR 954 03' (54,000 km), after purchase I replace the oil, coolant, spark, and brake fluid , and over the past few month has been riding the bike without issue,
recently I try to speed up the bike to 6000rpm on gear 2 and 3 (at speed 150km/h), and after that when stopping I play with the throttle up to 7000rpm just to hear the good sound for few second, and when I try to run the bike again at slow speed (20km/h) not long (20sec) after that I start to have problem where the engine will turn off by it self and when I press the engine start the engine will run again but few second after that the engine will turn off again by it self, and then I press the engine start again the engine will start but to keep the engine running while stopping I have to pull the throttle a bit just to maintain the idle rpm, if I don't pull the throttle the engine will turn off again by it self.
I look at the speedometer, the RED light is on (ussualy always on when running) and the only think that is not normal is the temperature, when I stop the temperature will raise high up to 123celcius and when cruising again it will drop back to 90cel but not stable, when cruising at steady speed (40km/h) the temp will go up and down between 90cel ~ 115cel.
after reaching home, I keep the bike off for 1 hour and try to run again the bike at slow speed (40km/h), and everthing seem fine, and then I try to speed again the bike above 100km/h for 2km distance, and the idle issue is happening again with temperature issue as above.
my suspect will be the temperature sensor is faulty, please correct me if I am wrong,
I am base in Jakarta (Indonesia) and its pretty hard to find part for CBR 954. in the next 2 week I will be visiting US
(Orlando) and planning to visit bike shop and buy parts that I might require for next few year (sproket, rear wheel hub rubber, oil filter, chain, clutch). I hope someone can help me sort out what is the issue is so I can buy the parts require when visiting the shop.
please also recommend what parts might need to be prepare for 12 year old bike with 54,000 km on the speedometer, seems old but the bike power still strong though.
if any of you have references for good bike parts shop in Orlando, please help to recommend me the name.
