Can't get my '83 Brick started. Help!

[colly]

Thanks guys. I had put some fuel injector cleaner in the tank already but I'll put some more in and give it a run. Good point about the air intake I'll certainly check that out.

If I still cant solve it then yes those injectors look like a worth upgrade. I live in ireland and he does not deliver here - can i find these in the UK for example? Any specific name I should search for?

[jakgieger]

They are "common" Bosch injectors from multiple applications...I would think that any reliable fuel injection shop/salvage operation would be able to find/replicate the application.

Am sharing the pain. So after the domestic jobs it's back to the shed to soldier on with flow charts. Am planning to swap the starter motor from the K1100 into the K100 and test fuel pump pressure, replace filter and check ECU power supply.

Regarding the 4 hole injectors: I have seen injector service kits where you replace the orings, screen and pintle cap.

Did not spend much time checking. You can look for the BMW K bike equivalent

The 4 hole end should be available. I know it's "only" $99 and you can probably afford it. Your call. I had mine serviced ($120). A screw is used to gently grab the screen in the top and pull it out.

There are a few "DIY injector servicing" on youtube. But as many people have said ... a good ride is often what some bikes need.

Not sure if it was answered: In Burt's Flowchart diagrams - "What's under the tank"
One pic shows the fuel injection relay on the front LHS and the other pic shows it on the front RHS. Can anyone clarify?

Re: the Colly's video of the bike idling: It's all happening - plenty of arse crack and the call off camera for "RAVS"!

Hey guys, so this week I'm going to test for air leaks and also clean the fuel injectors. Going to try to do it as per the instruction videos on youtube. Then at least I know I've tried - and see how she runs then and after a good run. If she still rough I'll look into getting the better 4 hole version - it would be a worthy upgrade I'm sure. The only thing is that postage to Ireland from the US is almost as much as the injectors themselves. I'm sure I can get them in the UK but I search does not find much. I believe there are a number of different models or manufactures that would slot right in, can anyone tell me what they are or what I should search for on www.ebay.co.uk?

Are there any other things I should test in the meantime that could have the bike running rough?

[jakgieger]

Test  one thing at a time in order to verify a solution/change. In this thread it has been detailed...fuel, fire, air (leak AND/OR restriction).  I found one injector by doing application search, bmw 318i, THAT LOOKS SIMILAR  :dunno2: .ebay.co.uk/itm/Bosch-Fuel-Injector-0280150714-for-BMW-3-5-6-7-Series-1-8-3-5-/222094187635?fits=Car+Make%3ABMW|Cars+Type%3A318i&hash=item33b5d85c73:g:-8cAAOSwubRXGXKn but it is used and cost 35 pounds plus shipping :nono.  Johnny's solution of just running injector cleaner is the best solution if you don't just want to throw money at the problem hoping for a solution...

[colly]

Wohoo! I got her Started!  :clap: Thanks for all the advice guys. I cleaned the fuel injectors but she was still running a bit rough and cutting out. We started hunting around and I found the big pipe connecting the airbox was loose. Took it all apart and connected it up properly, she stared on the button and purs like a kitten! So relived. Really appreciate you all taking the time to help.

Now the real fun starts :riding:

tHAT IS A FINE LOOKING MOTOCYCLE IN THAT PIX WITH YOU SQUIRTING IT WITH NAPALM TO GET IT TO RUN.

Congratulations, I told you the human would win!! Enjoy those beers that Johnny mentioned.

Colly,
Not sure how long your bike has been off-line. Mine sat for, I believe, 9 years. Needless to say, she was a little reluctant out of the barn. She made some funny noises (replaced monkey nuts),  replaced upper intake boots and the weird little "Z" hose. Never did have the injectors cleaned. The more I ran her the better she got. She returns about 50 mpg (to the Imp. gallon) at about 55 mph. No complaints there. I  think my lower throttle bodies (one or more) may leak a little air. I will do that test with a propane torch. Other than that she's 30 years old this year, 65,000 miles on the clock and I can't really complain. They are somewhat quirky bikes but she puts a smile on my face just about every day. I think she needs a fork brace, though.
Johnny swears by an additive called TECHRON...made by Chevron. I can't find it here in Ontario. I think if you can source a serious cleaning additive (not the junk at your local auto store rather the stuff a real mechanic swears by) then it's worth a shot.

Your bike sounds exactly like mine. Have just have success after a relatively windy road.

Am going for test ride #4 (each separated by some weeks) and noticed that my bike settled into a less rattly idle (output shaft ... the bearings are smirking at me ... I can feel the force) and

smoother throttle response when revving

I'm thinking either engine has warmed up and / or inlet rubbers have heated and swelled. Relatively abundant propane revealed nothing.

Anyone: thoughts or experiences on similar K 100 things?

I also like techron.  I also like STP fuel inj cleaner, and seafoam.  Todays fuel has alcohol in it, which I try to avoid (Caseys General Store, BP, etc)  It destroys fuel line in about 2 years, turning it into a fine black dust.  I replace fuel lines on nearly every bike I  clean carbs and tanks on. In KS and MO, usually some Phillips 66 and HYVEE food stores have  non alcohol fuels available.  These locations can be searched online.

If a bike has been sitting for a couple years, removal and cleaning or replacing injectors will almost always yield a great performance improvement.
