I've purchased a MOREY’S POWER BOOSTER LUBRICATING SYSTEM because it makes quite a differs and stops Backfiring of my 650. Can anyone help with info on where I should tap into the intake to put the feed line. Also what do I have to take off the scoot to see the area I need to drill. I have been using the Morley product by tipping the measured amount into the fuel tank at fill up so this will not be much different except I don't want to mess up the computer by introducing the oil into the wrong place.

Any help, brothers and sisters, would be appreciated.

Greetings....

Seems as though you drew a bit of a blank. I've read your post several times & am scratching my head. What on earth are you doing messing around with the fuel injection system on what is already a perfectly set up engine. The backfiring problem you see to have is due to incorrect settings in the throttle body's, which sit on top of the engine, under the forward section of the centre plate. To get to these housings, you need to remove the front top covers including the glove boxes and the cover below it (which includes part of the inner leg shields). It's not rocket science, but you will need a Manual to do this, so as NOT to break anything. Then, you have the top of the engine exposed and the fuel injection feeds.

I would politely suggest you take your Burgman along to your local dealer and ask them to re-set your injection system using their plug in computer and a set of vacuum gauges. At the same time, the pressure regulator on the fuel pump should be checked in case it is leaking (internally).

A little additive in the fuel can't do much harm, but in all honestly, why bother. You live in the most beautiful country in the world, go drive around it and enjoy!.... (watch out for the Speed Police, they are awful in the South!).

Basically on the 650 you've got a airbox (where the filter goes), then a resonator just above the throttle bodies, the throttle bodies, and a pair of short rubber bases connecting the throttle bodies to the cylinder head. I'm not so sure I would try to connect anything below the throttle bodies and in the resonator you'd have to be careful on where you placed any injection apparatus because theres air horns built in and in the wrong places it could pool and fill with oil (that's why it has a drain cap in the lower right corner). Ideally you'd have to find two places just below the air horns in the resonator box ahead of the throttle bodies. To access these you will have to remove the engine cover (maintenance lid), handle bar covers, upper box (upper glove box assembly), and front box (lower glove box assembly).

If you simply trying to reduce the exhaust popping I believe what others have done is to plug the PAIR valve hose coming of the resonator in front. It should be visable just above the radiator on the left side looking up behind the front wheel/fender.

Before trying any of this, please check your head light bulbs.
Wrong information has been known to be given on this forum, and before you touch anything 'injection', talk to those "WHO" really know.
From what I have read, this entire subject is nonsense, all of it.

When in doubt.... 'don't'.

 

[MJR]

Certainly I'd see if anyone here or there has ever installed or used such a system before on a Burgman 650 and seek their advise on it's installation and use. I have not installed or used such a system so I can only advise on where might be the best point to install it. After reading the intructions on their web site they want a place downstream of the throttle body but I'm not sure I would want to attempt tapping in those rubber connectors. Hopefully someone else will chime in on the subject. hanspluygers brings up a point in that such things one should be careful with as doing it wrong can lead to engine damage and if you were to drill anything to install it that should be done off the bike so as to clean and not get stuff in the intake.

MJR has some good words of wisdom here, MeterestNZ. You seem like you're trying to fix a problem (popping) that has a very simple solution (the PAIR valve)...but with a solution that won't do much more than lighten your pocketbook and potentially screw up your bike...badly.

If you're getting the popping noise, there's a fix for that. If it is truly backfiring, then the cause for that should be fixed ...before you introduce another variable into the system. Or you'll never know what went wrong and where to look to fix it.

Keep it simple. If there's a popping problem, have the throttle bodies checked by an expert.
Any work on the fuel injection system has to be done by an expert, with proper Suzuki compliant equipment.
And as it has been suggested, 'any work' has to be done with the system dismantled away from the bike.

In other words, leave it alone!....

If you really have to do this then you will have to have 2 feeds on to each cylinder
if you look round the engine side of the throttle body's you should find a short brass
tube with a rubber cap, these are the vacuum take offs for when the body's are balanced
you could use them. Wile I have never seen a 650 engine in the flesh so cant be absolutely
sure every Japanese multi cylinder engine I have seen since the 70's as had them.

Not understand why one would do this ! This need only TLC adjustment from knowledgeable technician.

Mine 2005 & 2009 never do that.

Thanks for all the input.

Perhaps I set many of you off in the wrong direction by talking about the backfiring as that is just a minor side issue. As far as all the major dealers in Wellington go, all Suzuki's backfire, or Pop if you like, and my Burg is working OK. That said, using Morley's makes the engine run a lot smother and reduces the popping.

The Morley system is just a delivery system for an upper cylinder lubricant that has been widely used in fleet vehicles such as taxies here. Many Wellington Taxies operators used the injection system very successful and got very hi mileages without problems in their Fords and Holdens (GM) cars. And no, I'm not saying that the high milage was because of the Morley's, although it probably did help by keeping the engines clean burning etc.

I have been using it in my UZ125's and the Burg for a while now and when I forget to top it up in the tank after a refuel you can tell the difference. Of course, its not a miracle worker either, but its not expensive and allows lower grade fuel to be used with little noticeable loss in performance. This is only from a subjective point of view, of course.

Some of you seem to believe I'm messing with the injector system of the scoot, not so, its just a simple drip feed injector type delivery system that puts drops into the air intake in a measured fashion. Actually, if I was designing the system I would use an adjustable metered jet taped into the fuel line before a swirl chamber to mix it into the fuel properly but I guess the drop into the intake air is simpler to achieve when dealing with large intakes on bigger vehicles. The plus is that you don't have to mess around with a squirt-bottle after each refuel putting it in by hand. I got a good deal on the system as it was on special then half price with my "Supper Cheep (Auto) Warehouse membership Card". Cost me a tank of fuel for the injector and included a Ltr bottle of Morleys. Actually, that makes the injector effectively free if you consider I would have purchased another bottle soon anyway, LOL.

All my expanding above notwithstanding, it does sound a bit more complicated finding a place to introduce the Upper Cyl Lub that is after the Throttle butterflies and the burg having two separate chambers makes it not simple as I don't want to upset the balance of the mixture between the two cylinders. Perhaps I need to put a mixer in the fuel line and let the computer to adjust for slight differences like it does for straight petrol differences. Apparently, there are bikes running the system but not sure if they are twins or singles, I will have to email the distributor and ask.

Has any one got any more thoughts in the light of my comments, (I have checked my Headlights, got + 120's as we are not allowed to retro fit HID systems in NZ). Has anyone had experience with the system in anything and have comments? I am just as happy with neg comments as I am with how too's. Its a possible project in the making I'm not worried about being told I'm stupid <smile>

This is for the '05 650 right? What does the injector look like and do you have a photo of it?

Honestly, I can't imagine a reason to do this.

The design of this engine is such that it will easily outlive the useful life of the transmission and the rest of the bike. Introducing a cylinder lubricating system is just not something it needs.

Not sure about the backfiring, which is usually an indication of an over-lean condition, often associated with a vacuum leak.

Mine runs as smooth as glass, no back firing at all, so not sure the purpose, but good luck!

Me neither, but then I'm not running the same fuel mixture as in NZ.......or at least I don't think so. Nor do I get a popping sound on my 650, that's apparently commonplace there. So I can only conclude that my circumstances are different from the OP's, I have no experience of their circumstances, so I'm unqualified to comment on how the standard Bike works, or should work, with their fuel mixture.
