Hi All

I am running these injectors after having problems with my original ones. I have been very pleased with them. They were a direct replacement for my injectors( 2015 SE). The filter fitted to them was an important factor for me as I had some corrosion in the fuel rail which probably caused my original problem.
I have seen the fuel spray patern of the originals and the repalcement Boch ones and it certainly looks a much better spray patern.
I have the blocked the motorized throttle control valve and the cross driilling in the throttle bodies and with these injectors it idles perfectly and feels clean all the way through the rev range.
 
"Beware eBay users selling 'cleaned' injectors without offering this service" :rolleyes:

I'm always wary of eBay sellers as is....

Interesting advert.
 
While playing with bigger injectors I bought some cheap new eBay specials and they were awful. Did better with second hand original Bosch.

Supposedly this man completely rebuilds and tests the injectors for the 961 from what I've read . He matches the spray patterns and flow rates , adds , filter screens etc... That sounds very interesting to me...

As FE said, at the price well worth a try, so I ordered some on Thursday and they arrived today with a service test report showing the performance. Injectortune are very responsive and so far I am impressed. As Stu mentioned, go direct and they are £65 including postage to UK addresses.

Ok I'm not crapping on this seller because I think injector cleaning is a good thing and can save some money, but this is some of the crap that drives me crazy because of misinformation. If you haven't noticed there is not a big performance fuel injector market. Even for the sport bike market there is not a big performance fuel injector market(throttle body upgrade yes) There is a reason for that and some of what I describe above is why.

And Ebay sellers that say "Photos are for illustrative purposes only" really chap me because if you are selling something specific I want to see what I am buying and if you are claiming it does something "better" then you better show me the statistics because what is shown here is nothing more than pure conjecture ( see what I did there!)

Most newer motorcycle and car injectors have four holes to help atomize the fuel better which helps on start up and also helps with emissions. This has been the standard for years now.

Typically there is a reason the injector got clogged, stopped working etc. Injectors in themselves are almost bulletproof not many components have a billion cycles service limit like injectors do Its always what is run through them or connected to them that causes the issues

As long as the injector is matched to the flow/pressure rate specified you will be fine. The Bosch injector or its equivalent works just fine as long as you can confirm its not gummed up. While we have fancy device for cleaning injectors you can do the same with a 9v battery and a can of contact cleaner and get the same result 95% of the time. You will notice most shops don't send out injectors for "cleaning" either. Again simple reason for this.

People trying to sell an injector that may or may not be better can only be proven with some really expensive equipment. The way injectors point have more to do with how well they function than someone saying it atomizes fuel better than it already atomizes fuel. I'm sure the people at Bosch know a thing or two about fuel injection. Also if you were to compare two similar good injectors of quality you wouldn't be able to tell the difference in spray pattern at all. also what micron is the filter of the injector as the Bosch or intermotor injectors don't have a filter. Personally I think with such a small run an additional filter is not needed and If the selling point has to do with the fuel rail then there are bigger issues if is rusting or falling apart.

We have run both Bosch and Intermotor injectors when we had a bike on the dyno and there was zero change in performance.

Also injection has a lot to do with the air that introduced so the fuel/air ratio must be controlled precisely which is why you have those fancy tunes in the ECU. You can have a single hole injector put out the same fuel as a multi hole and get the same results if tuned correctly. Also, if you look at many race engines that spend time at high rpm you they typically run injectors that have straight spray patterns.

Atomizing fuel isn't something new or revolutionary. Its like the split spark plug or iridium spark plugs etc. Manufactures spend a lot of time and money(except Norton of course) refining what works with their engine and if a better spark plug would help they would use it or engineer one, same as the injector. If they could eek out another ounce of mpg by atomizing fuel better or making the engine run more efficient they would as this also helps with emission.

And before we start the spark plug argument I am a big fan of Iridium but I've also seen where they are are not needed as well.

My 2013 CR was only firing on one cylinder. The steel fuel rail was rusted inside and flakes of rust had blocked the injector, which was an original Bosch. The injector doesn't have a filter although I can't see it would have made much difference, given the amount of rust. It was swapped out with an aluminium fuel rail.

That approach worked fine on my Bonneville recently. It had stood for 4 years and wouldn't fire. The injectors didn't look blocked but forcing some cleaner through solved the problem.

Anybody interested in a Fuel Diamond, 50 litres of Slick 50, a Turbo rain visor a Flowbee, some everlasting wiper blades ( I bought two sets) or a Breville Sandwich maker ? :confused:

But seriously, point taken CG, I appreciate the advice.

Right, but that's my point. The injector is rarely the main issue.

Just to clarify the inectors I changed were the unbranded type that Norton fitted instead of the Bosch ones they did their original development on. One of these was significantly under delivering on flow even after cleaning. The replacement injectors being sold by injector tune are genuine Bosch injectors used on a high performance engine. Their buisness is injector cleaning and refurbishing which you can see on their website, they are also local to me which is why I got involved with them to find a solution to my injector issues. I hope this helps.

There is no such thing as injector "refurbishment" on gas fuel injectors. Almost all gasoline-based fuel injectors are sealed units. saying rebuilt remanufactured, reconditioned, and or refurbished fuel injectors is at best misleading and worst a flat-out lie.

You can clean them, and also replace o ring, and filters but they are not disassembled in any way.

The replacement Bosch injectors are not "high performance" and while they are used on multiple applications including Chevrolet engines and other motors the only things they share are the standard specs like flow/pressure etc.

It's great they are local to you but I would recommend that if you are going to replace the current injector you do so with a "new" product as you know what you are getting. Also, there are other alternatives to the Bosch as they seem to be hard to find. Intermotor makes a good replacement that we have used multiple times with good results.
 
For those wondering the specs for the proper injector are

Bosch 0-280-155-931 lbs/hr 28.55 cc/min 300.1 grams 215.8 psi 43.5 bar 3
