Does this motorcycle have a radiator if so, make sure it's full if it is go online and see if there's a sensor that shuts the bike down when it gets too hot. Maybe there's something wrong with that
I had this problem today with my bike and after much ado I discovered there was oil in the air filter box... check your oil level it could be too full. Mines was and the excess oil was blown into the air filter box and as a result contaminated the air filter. Spent today cleaning the filter box, carb and draining and changing oil, could not get a new air filter today so ran it without onebike runs like new!! New air filter will be here Monday!
what kind of bike are we working on?? the avg temp for the elec fan to turn onis around the 220 mark. the best thing to do here is bench test the bike start it up and let it idle, put a fan that moves air in front of the bike, this will help to keep things cool while the bike heats up i know it kinda back-@ssward but do it. a inferred temp gun will help you get the temp, you can pick one up at your local auto parts store. check the temp near the senser for the fan and the radiator itself. keeping a GOOD oil, clean oil in your bike that will help with the cooling as well. If your running a bike with a fuel filter ( If your not GET ONE ) make sure its clean. Bikes with fuel pump, you a two types in tank and external, your in tanks pumps should have a filter on them in the tank, over time they get clogged like a inline filter and can cause poor running as well. If everything is working as it should you'll need to look into your coils. Heat causes resistance, resistance causes heat and heat causes wires to break down and contact points to to weaken. Coils take alot of abuse when it comes to electricity, it doesn't always happen but it does. coils go out and tire wear odd sometimes. I hope this helps you out if you need any more help please feel free to contact me Fix it right Ride it FAST M.Woodring
Regrettably, a small oil leak from the air cleaner assembly is "normal". This is because the EPA requires all crankcase emissions to be routed to the intake system so that it can be burned in the engine. The result is that oil mist in the crankcase vented condenses in the air cleaner and eventually drips out.
The crankcase vent for your Sporty is in the heads. If you noticed, there are two large bolts that are hollow holding the air filter backing plate on. The crankcase vents into the air cleaner assembly through these two bolts. There is an "unbrella valve" in the rocker box center section that allows the air to flow one way but not the other. There are baffles in this area to keep the oil mist to a minimum but still there is some in the air coming out of the engine.
There are a few kits available on the aftermarket for re-routing this crankcase vent. You can direct the exit anywhere you wish using one of these kits. Most people just route the hose down and exit it under the bike just in front of the rear wheel.
When adding oil to your bike, only add the oil when the engine is hot. On your dipstick, you have two marks. The upper mark represents "FULL HOT" while the lower mark represents 'FULL COLD", Do not overfill. Check the level with the bike on the side stand.
Hi Thats the float valve seals not shutting off, did you clean them & set the float heights? The overflows from the carb bottoms must also be blocked for the fuel to fill up the carbs which then leaks into the air filter Check also that the fuel tap turns off when bike is not running
you realy dont wont much do you!!!
keeping sand out the engine??? bam near impossible
all you can do is fit a grate big very very fine air filter witch will get cloged up prity fast and if its to small it will stop the engine from breathing the best filters are oil bath type were the sand is moveing so fast it gets thrown into the oil bath and gets stuck in it leaving clean air for the engine to breath but i cant see how you could fit on on a bike, you could try putting some trunking on the carb and fitting one to the rear of the bike, but it would still need to be serviced often
may look a bit daft too but if it saves the engine???
keep the air intake as far up as you can get it
The air cleaner(filter) also filters crankcase blowby . Oil accumulates in filter box and drains. The draining is to prevent oil from being drawn into intake an should be addressed by servicing air filter and cleaning out the box. Rapid and excess oil in filter is a n indicator that blowby is considerable. Hardrabbit starts and sudden accelerations play a big part in ring wear and blowby. I've noticed the use of filter sponge placed, not stuffedm in crankcase vent hosebef ore filter housing will separate oil from fumes before they get to airfilter and oil will drain right back into engine instead of collecting in air box. Some crankcase vents are baffled and have a seperation medium factory installed at the enngine end if vent hose. Do not plug the drain or crankcase vent hose. major leaks will sevelope. Over reving will also cause greater oil misting that is carried out the vent with the air. Good luck - note! rapid throttling affects fuel burning eficciency and tends to break down needed cykinder wall lubtication, hastening ring wear. have fun, be safe.
