These engines are pretty noisy up top normally. You can run at 65 mph in top gear all day. The most I have done is 400 miles in a single day. It took way more than an hour
Are you 2 still on the OEM sprocket set? Its a minor upgrade, buts its worth it. 17t front sprocket. Some where there is a thread here, where we have talked about the values of the 16t to 17t. (t=teeth)
What kind of speeds do you guys get at what rpm? My xs will go 120km/h (+-72mph) at +-8500rpm. I read that some people claim that their xs top speed is around 100mph. Are they able to reach such speeds and is mine therefore not tuned correctly? I cant see my xs reaching 100mph.
Mine is still accelerating hard at 70mph. I am sure it would easily reach 100mph, however, I have factory standard gearing, so rpm's would possibly exceed the red line with a risk of destroying the engine ( I am 6' 2" and weigh 196 pounds).
