Hey Tech Buddies, Bananatool
The XR pulls like mad through the gears but every now and again, like in the middle or late stage of over taking a car, in top gear the engine coughs for an instant before taking off again. It's not when you first crack the throttle on but at some point as it gathers revs toward the high range. Seems mainly to happen in top gear, like as it passes 100KM/h or more and is most noticeable under full throttle up hill. I ride mainly around Sea level and their is nothing on Bruny Island Higher than about 1,500ft. I am using Premium Unleaded either 95 or 98 RON, have drained the carby, checked the airbox/filter nothing obvious. I have owned the bike since new in 2000 and have only done 5,000KM on it and it has had no modifications. Any suggestions most welcome.
Thanks Heaps

Have you just drained the carbie or have you cleaned it really well ?
As that is not the same .

"I have owned the bike since new in 2000 and have only done 5,000KM on it and it has had no modifications"

There you go matey, that's your problem - ride it a bit more frequently?
5000km / 14 years = ...... umm, oh wait, eh (sweat), well, it is WAY less than what Mauser rides per weekend!
You see, using it is not abusing it - ride it!!!!  razz

Yep, drain the entire tank, not just the carb & replace with good fuel (can you get 98?).

Geez BigOne, that's not a very clever question to ask an Ozzi from London  Embarassed 
Let me do it for you: "Can you get 86?"


You see, he is on the opposite hemisphere, so you have to write the numbers upside down!
