It will not damage the engine at all. All that will happen is that it will run richer, thus using more fuel. If you did it for thousands of miles you'd probably end up with more deposits in the engine/exhaust, but even that is easy to sort.

Un-sprung Weight With all vehicles, un-sprung weight is the holy grail of handling. Un-sprung weight reductions result in a wheel getting back to the surface area it's adhering to in less time. The result is frequently less over-steer in cars and in motorcycles, less low=sides due to interruptions in friction adhesion to the surface. Un-sprung weight or ...

There are scientific explanations for this. The long and short of it is that the rear tire bears the most weight just the same as a bicycle. ( Brian, if you weren't in OH I'd say let's go for a ride so that I can witness your phenomenon ) http://bicycles.stackexchange.com/questions/14517/why-do-i-always-get-punctures-in-my-rear-wheel ...

You can try heating it with a torch to loosen it. You could also get a reverse-direction drill bit, and drill down into the bolt; the heat will help the reverse bit to unscrew it, and if not then you can easily get the remainder of the bolt out by stepping up bit sizes.

Check the compression. If something is causing a loss of compression, like worn piston rings, then that could be the reason for all those problems. Push starts creates higher pressure in the cylinder because it moves the piston faster than a kick start. Also, it could start cold but not warm due to the temp of the air being brought into the cylinder. When an ...

I guess this is hearsay, but I have a couple of friends who store a scooter and a 125 learner motorbike in their apartments, and they don't leak any oil or petrol - they are quite new though, so what I would advise is to have a good look at the scooter to see how old it is - if the engine is old it may have worn seals etc which may leak. In any case, get ...

If your last paragraph is the question, I think it is far too broad. You would be best off getting the manual and with its help: reconnecting anything that should be connected cleaning anything dirty or full of insects etc check continuity of all wires individually and replace any that are faulty check spark plugs check air inlets move all mechanical parts ...

Tire Pressure correct, less rolling resistance. Weight reduction: You, cargo, and extra accessories. The less weight the better the fuel economy. Slow smooth acceleration, no jack rabbit starts Anticipate stops, let off the accelerator early to start slowing down as opposed to keeping the gas on longer and using the brake harder. Eliminate unnecessary ...

Instead of recreating the wheel, here are some pretty good reasons why you need to do a break-in on any engine, be it a motorcycle or a car. I found it on this page. I don't necessarily agree with everything the person says on the page, so I'll leave the rest of the reading up to you. The What: Every new engine has internal components that must be ...

The first things to check that come to mind... Make sure all the fuses are in place. He could have pulled one or more. check that the spark plug wires are connected tightly to the spark plugs and distributor. check the electrical connections on the ignition coil. check the electrical connections for the fuel pump and fuel injection if it is injected. make ...

Sounds like you are talking about a Vespa PX - according to the manual you should get 260Km on a tank. I think this is if you are a very small Italian and travel at a constant 60km/hr. Specs for newer Vespas like the GTS 250 have to conform to EU measurement standards and therefore are more realalistic. Your 150 km is about what I get for mixed riding - I ...

While I don't think there can be a specific answer (it may be due to your bad luck, or whatever), it may come down to the fact there is more weight on the back tire than on the front. The front tire can more easily overcome a puncturing obstacle such a nail or a screw, which the back tire picks up. It may also be that the front tire kicks up the obstacle and ...

The 'worst case scenario' that I can think of is this. Your spark plugs become fouled because the motor ran too rich and the bike doesn't start. You would need to remove the spark plugs and clean them with a carb or brake cleaner and re-install them. Don't worry about your vehicle. It's fine.

The information provided by DucatiKiller is excellent. I believe the biggest advantage is access, which makes wheel changes and maintenance arguably easier. This could also translate to pit-lane advantage in racing situations. Particular case - in the case with Ninja H2R - Having a single-sided swingarm allows the exhaust pipe to be mounted ...

Just remembered that I hadn't posted an answer to this and thought I would just in case someone else has a similar situation. I ended up taking off the ignition cylinder myself (was easier than I thought). Turns out that the ignition cylinder had a a metal rod inside of it that is supposed to turn when you turn the key but it was broken so instead of ...

Agree with @mikes ... your issue is lack of fuel. That "hollow/rattling" noise is pre-ignition/knocking caused by a lean fuel condition. If you keep trying to run your scooter like this, you will blow the piston out of it (if you haven't caused damage already). You'll probably need to rejet the carb and get more fuel into the system. The reason why it ...

If your clutch is burning out so often, maybe it's slipping - check the adjustment of the clutch lever by loosening the locking nut and turning the adjustment (it should engage around halfway on the lever and by fully engaged before the lever is fully out). The kick start may require the clutch to operate.

Answer: the plastic screws are really delicate and they do not turn with enough accuracy to really unlock the panel. The only way I have found is to insert a lever and pull harder, and the panel comes out without breaking anything.

The upper hose that you found cut and zip tied is likely to be a vacuum line, rather than a fuel supply line. (image credit www.scootusa.com) If so, the fact that it is cut and plugged should not be causing your failure to start, it is likely an emissions-related feature that is activated when you get off the gas.

Check intake + exhaust valves, thay aerial more than likely the problem. they have to be set every 1000 miles, otherwise no start or hard start in cold.

That kind of leak can be quickly fixed with gasket silicone (which is VERY cheap and great stuff, I use it everywhere because its easy to use, tolerates high temperatures and seals oil better than the regular gaskets! You can use it together with the regular gaskets to get a seal that last for life! However in your case it would be a temporary fix, if you ...

First thing you should do is get the engine nice and clean using some good quality degreaser, a brush and a hose to wash it down, this will make identifying the leak much easier. After everything is nice and clean take the scooter for a 10 minute ride, then have a another look. This time it should be much easier identifying the source of the leak. Most ...

I usually get 220km per tank at about a 80kmh average start to stop including 100kmph of 30kms on the freeway everyday. i do 500km a week. run a pipe and porting on an otherwise standad bike PX200. I recon at 60kmph and taking things easy I would get about 300km on the tank but that would be a long ride...
