I thought it could work more like a supercharger, except it will be powered by battery instead of engine. This isn't the first time someone has thought of "electric" supercharging. There's nothing wrong with having electrical power source per se (the leaf-blower Monza comes to mind), but you're going to need way more than 10 W worth of power (which is what ...

Stopping a naturally aspirated engine will cool it down, regardless of the fan running and etc. The idea behind "turbo timers" on turbocharged cars is not at all engine cooling related, rather it is to allow the delicate and extremely hot turbocharger components to cool down via keeping the oil feed circulating through it for additional 15-30 seconds or a ...

Using that kind of blowers as turbochargers is generally proved worthless. The main drawback is these devices are not capable of creating any significant pressure, especially considering internal combustion engine's air flow rate. As @HandyHowie already mentioned one could even experience air flow restriction. Some quick maths: consider 1 cylinder 2 stroke ...

Short answer: Yes. Long answer: Maybe? As long as it is a 12v motorcycle starter relay you should be fine. The problem is whether or not it will fit your bike physically (that is whether the size of the solenoid will fit into the compartment designated in your motorcycle, and whether you have bullet, spade etc etc). I have used a few of the cheap Chinese ...

If I am not mistaken the 2001 Yamaha Diversion has a clutch cable and does not have a hydraulic self adjusting clutch mechanism. This was my son's first motorcycle and we experienced similar issues with his. I will say that this model is bullet proof. Especially the 8 valve air cooled version which you have. Throw Out Bearing If your throw out bearing is ...

In the image below notice that there are no rocker arms or push rods. The cam acts directly on the shim and bucket which acts on the valve stem. You adjust the valves by changing out different shims to get the appropriate valve clearence. In this image, the shim is over the bucket. This is what your Yamaha has. You have an Over the Bucket Shim to adjust ...

High Spot If I were to guess, you have a 'high spot' in your chain. Cause High spots have occur for a number of a reasons Ongoing poor care Low quality chain 'Clutch Dumping' which causes stretching of the chain. Water penetration of a few rollers leading to rust and inconsistent where on those rollers Remedy For now, adjust your chain to the highest ...

The DT 230 Carburetor will fit on some DT200's The 1999 model of your bike uses the Mikuni TM30x1 Flat Slide Carburetor Older models use a different carburetor model. The slide is round. Here is an image of the flat slide carburetor. Here is an image of the round slide carburetor Both of these carburetors are readily available on ebay and Google shop.

More than likely, you have an air leak If you haven't cleaned out and rebuilt a bunch of 4 carburetor banks in your life there is a good chance you have accidentally created an air leak in the system. Unmetered air will create the symptoms you describe. The giveaway on most lean conditions is the falling idle. It idles high and is getting enough fuel but ...

These symptoms are typically caused by one or more blocked jets in the carburettor. Small particles of grit can block any one of the jets in carburettors. The fuel still gets to the engine through the other jets but the efficiency is much degraded. The number and size of the jets varies by model. I have no experience with Yamaha motorbike carbs but I ...

The exact answer to this is - It Depends... The reason for this is that your existing ECU, whether it be on a bike or in a car, has a range of inputs and a range out outputs, and a mapping between them. As long as your inputs are within the ranges expected, it may well be able to cope with the changed architecture, however there are two common problems: If ...

There is no need to reprogram the ECU This is for a couple of reasons: The engine barely feels a difference Contrary to what the name implies, a "free-flowing" intake impacts the pressure at the valve inlet and not the volume of fresh inlet air per cycle. Here are the numbers to back it up: K&N provide detailed test data for the Yamaha R15, which ...

Breaking in the engine correctly will greatly affect the longevity and performance of the bike, plus you have warranty regards to worry about as well. I found this from a Yamaha forum and seems along the lines of what I understood to be right: According to Yamaha, you are to keep the engine below 5900 rpm for the first 600 miles and vary the rpm. Do not ...

Check out the Yamaha web site for the models you are interested in. They should list technical specifications for each model. If you are concerned about performance differences focus on peak horsepower and peak torque at a specific rpm along with top speed.

The 2012 XJ6 is fuel injected, so an aftermarket exhaust (Arrows, Leo Vince, Scorpion, Two Brothers, Akrapovic etc) would be easily procured. You may even get good deals on used slip-on exhausts, and you could then re-pack the glass wool (other as applicable) if required. In order to keep the cost down, you could opt for a slip-on exhaust (muffler) instead ...

Yes, you can relatively easily determine if your fuel filter is clogged. The XJ600 has a vacuum operated fuel pump below the downdraft carb bank. This is what it looks like. The stock fuel filter is an inline filter and this is what it looks like. As I'm sure you have noticed, the filter is a bit opaque and you can see if it is clogged. It's very easy ...

If you synchronize and clean the carburetors the bike will not have the same power that it did before you removed the baffles from the exhaust system. The baffles created back pressure in your exhaust system that restricted the flow of the exhaust gasses. When you removed the baffles it allowed the engine to 'breath' easier due to the lack of restriction. ...

I don't know for sure, but would bet your best option is the last one. I know straightening tubes of any sort is a very hard option. There should be an Allen head bolt which is clamping to the forks. You don't want to take the fork loose if you can help it, as getting alignment back right could be a huge pain in the butt for the uninitiated. If replacement ...

According to this User Manual on Page 53 (section 6-3) a Valve Clearance check should be carried out every 26,600 miles (42,000km). It also highlights any other maintenance that should be done and at what intervals. I think checking is relatively simple (assuming you are handy with a toolkit. I found a site that gives this method of checking your valve ...

Most Kick Starters Have a Relative Position They Need To Be In What I mean by this is, you can get your kickstarter into the system and mount it up bet if you do not put the shaft in at the correct degree it won't operate properly. Think of cam timing. Perhaps a poor analogy but.... Look at this parts diagram On shaft 9 and gear 11 you need to have them ...

There are a few ways to resolve this dent issue. Method 1 glue these plastic ding tabs to the gas tank. You can find them by googling "plastic ding tab" You will use a hot glue gun and hot glue them to your gas tank. Use a dent puller slide hammer. The tip should screw into the plastic ding pullers. Pull the weight of the slide hammer to the ...

Exhausts can be difficult to remove. In many cases constant heating/cooling has burned off any coatings and the bare metal has corroded or rusted the nuts and studs together. If the exhaust has cylinder head studs with exposed nuts you can try several things. Start by soaking them with a penetrant oil. Only do this when the exhaust is cool enough to touch....

I would suspect one of two things. Your main fuse is blown. This would disable your entire electrical system and prevent the bike from lighting up or starting. Your ignition switch has failed. If your ignition switch where you turn your key has failed your electrical system will be dark. If you have a multimeter you can unplug your ignition switch from ...

There are quite a few things that can effect your bike in this way First, you need to truly identify the issue. Before you tear down your carburetor you may want to engage in some troubleshooting prior. You said When ever I am driving in low RPM, I feel like the fuel is cut off in short sharp intervals. And even with the Idle RPM adjuster screw ...

You may have a bad PCV valve or your rings are getting worn out Your PCV valve controls pressure within the crankcase and assists in dispensing excess oil and running it through the engine as well as ensuring that an excess of internal pressure in the crankcase has no negative effect on your crank and transmission seals. It is normal for the crankcase ...

There could be a couple culprits here. First of all the clutch might not be adjusted correctly so when you pull the clutch in, there is still a load/pressure on the gears so when you go to kick up or down you essentially forcing the gear to slip from one to another. To fix this, lube the clutch cable and the lever then play try different adjustments on the ...

I would not be worried Your motorcycle will exceed these temperatures by far while running. Especially beneath the fuel tank which is directly above the engine. You can expect normal operating temperatures well in excess of 180 degrees F beneath the fuel tank. In regards to humidity, the AC unit should be draining water removed from the air of the space ...

Reserve on some motorcycles bypasses the vacuum valve When you are using the 'reserve' position on many older motorcycles you are bypassing the vacuum operated 'ON' position of the petcock. The vacuum operated valve is a safetly feature so that fuel will only flow into the carburetor when the engine is running and creating a vacuum. There is a vacuum line ...
