i have a 99 cbr 600 f4 it only has 36.489 on the bike but lately when i am off on one of those i dont care were i end up rides after she gets good and hot she wont start till she cools down anyone have an idea whats up

 

When you say "hot", do you mean operating temp hot or overheating hot?

Are you using choke when you get it finally get it restarted? Do you normally have to use the choke when the bike is cold?

 

no its normal hot doesn't over heat that what i don't under stand

 

also no i
never use the choke when cold she start like a champ

 

Does it act like it has no gas when u try to restart it? But if u let it cool down for awhile it'll start right back up? If so I'd say r/r

 

I have the same bike too with a similar problem. So far there are lots of posts offering ideas. However, specifically this is what happens with mine...starts up when cold. Heats up to normal temp. If I switch it off and try to start, there is not a sound coming from any part of the bike until it cools down again. Replaced the battery and tried again. No change. Checked the starter relay when cold and it clicks as normal ( obviously if the bike starts). Tried again when hot, just one click and then silence. Next step is to bypass the relay when hot to see if it starts. If it does then it's possible that the relay is goosed. If not, then apparently it's the starter motor (not so good). You might try doing the same.

 

Replace you RR , had the same issue. When hot the rad fan drains up all the life in the battery. RR must not be able to charge the battery well, check the voltage when bike is hot and running at idle.

 

It always could be the battery.

One of my friends (also a member here) had an issue that his bike was VERY hard to start when warmed up - he replaced the battery and all was well after that.

 

thanks for the suggestions I will try that thanks let you know

 

Folks. It's been a while but the bike sat in the garage for the winter (not a commuter bike anymore). Now I decided to tackle the problem. I let the bike idle until it got to operating temperature. Once the fan kicked in I turned off the engine and tried to start it straight away. As expected, it did not turn over. Not even an attempt to turn over.

So I bridged the gap between the Positive and Negative terminals on the starter relay with a pair of pliars. It started straight away which I expected. So that rules out the starter motor, battery and possibly the starter switch.

I'll replace the starter relay asap but until then I just need to carry a pair of pliars.

Hope this helps.
