My name is Espen ,and i am 48 years old. I am from Norway, but live in Sweeden. I have been riding motorcycles sinse 1982 , but this is my first offroad type motorcycle. I have a 2008 660 tenere that i bought in July 2012.The bike has skid plate,crash bars, aluminium side casas, heated grips, hand guards, mainstand, all original Yamaha parts. I have done 4000 km on it, total km on bike is about 8500km. I love it, but there are two problems for me.

1. I smell petrol when i accelerate and change gear,bumpy roads, and offroad . the smell i think come from the tank lid. I know the new 2011 abs tenere have a different petrol tank with 2. stk air wentilation hoses from the tank. One is directly fron the underside of the tank lid where it have a rubber conection to the wentilation hole from the petrol tank through the tank lid. The 2008 does not have this ,only one hose on the side of the filler hole. Is there something i can do with this petrolsmell ?
2. I get a lot of pain in my tailbone just after 30 minutes of riding. Have anyone tried to take off the seatcover and tried to cut a wedge in the seat to create more space for the tailbone ?
Does a Airhawk cure the problem ?

Thank you for a great informative site, and i hope someone can help me with my questions.
Regards Espen

What the Coccyx are you talking about?? You want to add more softness not reduce it, probably a gel seat lining would be some relief on your whatsits

Hello,:-) yes i have tried gelseat but dosent help.

I am now serious and not kidding, have you been to see a doctor, because I tell you for why, when I was a young lad, I was doing regional motocross racing and winning every race until jumping and landing became a pain in the Coccyx and I went to my doctor who found I had an advanced state of cystitis in that bone and he had me operated within the week and I was ok ever after. The doc removed a whole section of the last bone which had about 8 cysts.

Ok, best to see the doctor then.
Thanks for the info.

I think when Espen was talking about removing material from the seat, he was thinking of relieving pressure, a bit like the groove in the middle of many 'anatomical' bicycle seats, which remove pressure from the perineal nerves (leading to numb willy syndrome). It's certainly a recognised way of dealing with pressure discomfort, and simply making the seat softer sometimes makes things worse, not better.

But everyone's @rse is different, and much of the time it's a case of ... I was going to say 'suck it and see', but maybe I won't.
