This Is The EPIC Soggs 92K75 MAGA Thread

[szabgab]

Hi Guys.
Took the injector rail off and pulled the injectors out. They were in there well! What’s the best way to clean them? Would a sonic cleaner be any good? Or flush them through with carb cleaner, while intermittently connected them up to a 12v source?, or both?

Hey Soggz, all of the above will help. Although I think the general consensus is, you will never be able to get a properly clean injector done with household methods (but they will definitely improve things). I had my K75 since August and I have done EVERYTHING on it myself with the help of this great place, even if the  go-to K bike specialist of the region resides not 15 kilometres from my house. There are a very few things, I will be tackling with the help of the pros, and one is a professional injector cleaning service, as they operate the injectors in a special rig opening and closing them in quick successions some 10.000 times whilst sitting in an ultrasonic bath, replace the screen, o-rings and give you a before and after chart, all worth the 30 or 40 quid they charge for that...

Thanks for the reply. Yes, I have emailed 2 companies in the area for a quote to clean them. I watched on YouTube how it was done, and yes, the professional way,is the way to go!
Thank you.

Hi,I took it for a quick ride last night,and it ran like a bag of nails. I'm thinking injectors are dirty,so they will be sent off for cleaning,all in good time.
I noticed while Imwas out on it,changing gear seemed a lot more difficult than on my Honda. Particularly,it seemed quite clunky.
Is this normal,as I'm not used to a dry clutch.
Thanks.

BMW's transmissions are known to be a bit clunky requiring a deliberate foot movement, but mostly on the Airheads and classic K's.  The later K1200's had smoother shifting transmissions. Excessive effort to shift gears is also an indicator that the clutch splines need attention.  Have you been into removing the transmission from the bell housing and inspecting the clutch yet?

Hi.  I, engine is still in frame. At the moment, I am concentrating on getting it running right,  it I will be paying attention to the splines once it’s running better.
The rear wheel be coming out, as the valve is leaking air,so the splines will be looked at then. Once they are checked over and lubed and it’s running better, I will take it out for a longer ride to see what else needs doing. I understand from other people too, that changing gear on these bikes are harder and more methododic.

For the clutch splines you don't have to remove the engine, it is like a car engine with separate parts bolted together. If you have the final drive, rear wheel, calipers, etc off you are halfway there for the clutch splines. If you do not plan on removing the clutch itself, it is a reasonably easy and straightforward thing to do. Also I would probably replace the gear and final drive oil and add some moly additive to the gear case, (that probably helped with my clunky gears although it is hard to say if it was that, as I was doing many other things at the same time). My ancient CB400N in a rather sorry state had buttery smooth gears, compared to that the K is a chore, but you'll get used to it. The gear indicator actually helps, as you'll learn to have the indication in your peripheral vision - if you've found yourself between gears, the indicator shows nothing, so you'll know to try a bit harder :))

Ok, thanks for the reply. Yes, I understand that it is just rear wheel and final drive,removal to line the splines. Hopefully, that will make the gear change a little easier. I have also gone out and bought more oil for the gear box and drive box?().

Find some Moybdenum disulfide powder, 1.5 micron on eBay.  I add a couple heaping teaspoons to the gearbox oil and a little to the final drive.  After a couple hundred miles to run it in the ease of shifting is noticeable.  My bricks shift almost as easily as I remember my Hondas shifted. 

Another thing I've learned is not to pull the clutch in all the way.  A light flick is all it needs.

I followed the Mighty G's advice and can attest to an improvement after adding moly powder to the gearbox. Note, it's nasty stuff and will stain just about anything not metal you let touch it. I used folded paper to guide the power into the opening.

[Soggz]

Thanks. Sounds interesting, can’t say Ive heard of it. How much of it comes in a packet?

2 oz is enough to maintain a fleet of bricks.

Find some Moybdenum disulfide powder.....

Hmmm, I may try that in the Ural.  Any idea if it lubricates igneous rocks chipped roughly into the shape of gears?

Thanks, I shall look it up. Is this stuff used widely?

Seems expensive...

Well, that is expensive, but this one is a better deal - https://www.ebay.co.uk/itm/1-x-Bottle-250g-98-0-Molybdenum-Disulfide-MoS2-Powder-Reagent-Lab-Chemical-New/254000764083?hash=item3b23a014b3:g:~AUAAOSwzaJcCQEw:rk:1:pf:0

Over four times as much for quarter of the price...

yeah, I looked up the amazon.co.uk price too and I was floored. "Chemical shipped from the US" = expensive. It's like $13 delivered here - £10 maybe.

Unfortunatly,everything that gets shipped here at the moment,seems to be expensive.I blame brexit...

I was in the states last October,November,and can't believe how much the petrol costs there! It's about the same as bottled water here!

Thanks very much. I just ordered some. My son said he will pay for it (bless him), as it's my birthday tommorow.

Yeah, over here, bottled water is actually more expensive than petrol.  And tap water is more stringently regulated.

With fuel prices like that, who really wants to save the planet with alternative power? Too little, too late!

greetings...

you put a quarter gram of that in a tall glass of chocholate milk every morning and you will have tremendous regular movements...

Ok.
Injectors got sent off yesterday and bottle of that black magic powder is on its way.

BTW, I'm searching for an "air accumulator" (fuel overflow catch cup):

£7 for the part, £45 shipping to the US. I guess it works both ways! wink
