Bandit1200 temp when tuning

[Wigwam]

Gas flowed head for a bit more power. Downpipes now getting cherry red when ran at 2500- 3000rpm. I know it's a fuel thing but has anyone took temp readings. There's a lot of variables but wondered if I could use temp readings when tuning. Any insight or advice appreciated.

Usually around 280-300 degree celsius on tickover

Sounds like exhaust cam related

Could be fuel but also Ignition - excessive retard or no advance from idle wouldn't help! At low rpms quoted there shouldn't be excessive heat - something is wrong, not bad tuning - its wrong!

Camchain out by one tooth?

Just to re-iterate what others have said, if your headers are getting cherry red at 2.5k something is very wrong.

Either your exhaust cam is early, your ignition timing is late, or the bike is running lean AF and getting very hot.

Investigate and fix it fully before using it else you will kill the motor sooner or later.
