I was woundering about it being to much stress on the motor when it is running on the road. I dont want to tear it up.

Never had any problems with mine yet! Its a 426... you cant kill it. Just dont drive 10 miles on the rev limiter and you will be fine :banghead:

They're geared low, even when geared higher for the street. The result of that is what I call high "piston mileage". The engine is built to rev, and rev freely, but each revolution is a trip up and down the bore for the piston, and all the other parts of the engine, for that matter. So, it ends up being a question of how far the engine has to go in an hour's time almost as much as how much load it has to carry.

It's not exactly bad for it, but it isn't good for it either.

I dont think its any worse for it than being on the rev limiter all day in the dirt.. I know a few other guys that have them street legaled too and so far I'm yet too see any engine damage due to street riding.

yeah i would definetly put a smaller rear sprocket on it. that way you can just cruise on the highway without being at 7,000 rpm.....

In addition to what gray said, the street is harder on the drivetrain in general because there's no tire slippage like there is in the dirt. Harder on the clutch tranny, chain, etc. Also, in the dirt you're constantly raising and lowering rpm as opposed to more constant (high) speed operation on the street. A 426 will be a real pain in the ass on the street, go with lots of flywheel weight.

I would be more concerned with overheating in stop and go traffic than anything....

Is that legal over there or do you just split lanes anyway? Cant do that here in Canada... well not when there are cops around anyhow.

Let's just say it's not illegal. Even the CHiPies do it. If a cop thinks you're doing it unsafely, though, they can cite you. The ticket will be for either unsafe lane change, following too closely or reckless driving. It all depends how badly you piss off the cop. If I couldn't lane split my Harley I wouldn't ride street much. It makes no sense to sit in traffic sucking fumes and adding to the congestion. It can be done safely and makes riding a bike in Cali an advantage, especially with gas at $3 a gallon. I used to ride 17 miles one way to work every day. In the car it took 75 minutes or more, depending on traffic. On the bike it took 25-30 minutes tops.

White lining, splitting lanes...they both refer to the practice of riding a street bike in between cars in traffic. Here we can do it on surface streets or the freeways. Makes getting through traffic a lot easier.

If you run the bike at moderate to high revs (4k-6k) for long periods of time, your gonna be using more oil than you would in the dirt.

Higher RPM's demand more oil flow, and the motor does a good job of putting the oil where its needed. Some of this gets by the rings and valve guides. Check your oil level more often during road trips, you'll see a difference.
