Hi, Is it normal to sense a petrol smell from the exhaust even if the engine is warmed up? Even after 30 minutes of riding I can smell petrol coming from the exhaust is she running rich?
My fuel consumption is also not that great... I get around 120-140 Miles to a tank(15L) and thats city riding, which i think could be better

your consumption is about level with mine so you're not burning huge amounts of excess fuel, what year bike is yours?

that is good mileage for around town, I'll get about 110 to 15L in town comuting!
but my exhaust is half the size and i have no snorkel in my airbox!

get out on some nice roads and you'll see a lot more miles to the tank!
Before i started changing things i got 190 to a tank.

Wow i used to think there was something wrong with my consumption. Ive never been on some nice roads for long to see a huge difference in my consumption.
My bike is a K5 pointy so is this petrol smell normal then?

I've noticed a similar thing at petrol stations, you can smell the stuff everywhere! I did tell the person behind the counter last time I was there (this morning) but they didn't seem too interested. Very strange.

No TBH, they don't usually smell very strongly. It suggests unburnt fuel which could be a running problem or it just needs a bit of atune up. New air filter, balance the TBs and set TPS. Otherwise it may be running in cold start mode all the time suggesting a bad temp sender.

Or it could be something and nothing.

Do you have an aftermarket exhaust pipe with a gigantic hole running through it?

ie...no baffles, and old packing within?

Nope everything is stock, air filter is still new, i think i may need to check TBs and TPS
