Morning Brickers

Lots of thought of where I will put the ignition switch. Played with lots of ideas and then decided on the following using another piece of the recycled sign.

Good Morning World.

Spent the last few days finishing off the Machine and then took it for its MOT. The garage where I go are very accommodating and looked her over before the test and advised me of the following.
Under new legislation the indicators on a motorcycle over 50cc need to be more than 240mm apart at the rear and more than 300mm apart at the front. When you consider that a 7 inch headlight is only 177mm wide that means that unless your Bike has long stalks it could fail an MOT. The tester told me that most bikes already fail this requirement!
Anyway I need to add extra indicators to the rear, he will let the front go through. New indicators ordered.

Also the rear brakes were binding. I had bought new pads and the inside pad seems to be dragging. When I looked closely it seems that the rear calliper does not sit centrally over the disc. There was not any shim fitted when I took the disc off for cleaning and I could not see any on my Haynes manual. I ended up sanding down the inside disc and it's moving freely now.

I need to play with the bike a bit. Its running a little lumpy and I'm getting popping and the occasional backfire. Wakes up the pedestrians  :hehehe. The bike starts on the button and idles ok. Does not need the choke either. I think I may need to look at the air mixture or possibly ignition timing. If I get no joy I will post a video.

Looking refined and elegant, Skunky! Thanks for the vid. Good luck with the MOT. It must be wonderful to be so well-protected from yourself. :giggles

I think OVERprotected is more apt Laitch  :clap:

Popping is most likely an exhaust leak, either at the head or the header to silencer connection.  Also, you need to completely close the throttle when decelerating.

Lumpy running may be varnished injectors.  A couple tanks of fuel with fuel system cleaner run through at high rpms can help this a lot.  Possibly one of the most enjoyable service procedures you can do to your bike.

Hi Gryph, I agree whole heartedly, I need to get some miles in and get the injectors cleaned out. I've added fuel/injector cleaner into the tank and will continue to do so for at least 200 miles. As for the popping and backfiring, i'm suspecting either air mix or temp sensor as it was running rich before work commenced. Again though as the bike hasn't run for 6 years I need to get everything settled down first. Every time I ride it gets a little better.

I should get the MOT done on Monday/Tuesday next week then I'm burning up miles.

My 16V K100RS had sticky injectors when I got it.  They weren't bad enough to justify the hassle and cost of removing and sending them out for cleaning so I ran cleaner in the tank for a thousand or so miles.  I still remember when they finally broke completely free, what a sweet feeling!  Like a supercharger kicking in.

Good luck, Skunky!

Neither my front (either side of a 6.5" ShinYo headlight) or rear indicators (bolted to either side of the frame hoop) are 300mm apart, Triple S went through with no advisory's, MOT Testers discretion I believe.

He's letting the front go through which are 240mm. But he wasn't happy with the rear LED strip indicators when the brake lights were on as the yellow doesn't show clearly, so I'm putting a couple of additional ones on. TBH I had to agree with him. He also pointed out that the new headlight beam isn't the right shape. But as it's an e-marked light he's letting that through too. It just goes to show that even if you buy e-marked gear made for British roads they still might not be good enough.

Brotherhood of the Beemer hear my confession. Insanity! Distraction! or Just Early Stage dementia I am not sure......

Last Sunday I took off the rear tail piece,(which I had so lovingly created using a broken tail from an RS instead of the slightly clumsier tail from the LT), In order to fit some additional Indicators to satisfy the MOT gods. Fitted the indicators and later that evening went for a short run down a fast dual carriageway for a "check everything was OK" joy ride. Got back home minus the tail!!!!

Went back out and recovered it.

And this.......

Became this.........

To say that I was pissed off would be an understatement. But it was me that put the tailpiece back on, and me that didn't put the screws back in. Oh and me that has to bear the bits falling off criticism and the "what else haven't you done up" Jibes from her in doors. 
I quickly knocked up an alternative tail from the LT one that I hag in the Garage (As you Do). But it doesn't fit the seat properly. I managed to get another rs tail unit from DJ Ewen which I will start work on this week. 



Apart from that the bike is finished and on the road and getting better every time I ride it. I will take the time to take some more photos etc and paste them up when I get time.

Hi Beemerphiles

My BMW gets better and better I can see why you love them so much. I have created a hooligan with a sofa comfortable ride

Anyway Thanks to DJewen who sold me the tail from his bike so that I could replace the one that I smashed, I decided to change the design slightly to sink the light strip in flush.

Side Stand Mk3

When I first got the bike the side stand was snapped so I sourced and and purchased a replacement from fleabay. Cleaned and painted it looked ok. About the second or third use it snapped in the same place as the original!!!!!. After gnashing my teeth and cursing purfusily. I threw my hands in the air and said f##k it, I’ll use the main stand. Anyway come the real world of daily use, I soon realised what a pain it is on my slightly sloping driveway. Stop the bike pull it on the stand, open the garage, lift it off the stand drive in, lift in back. So the answer is get another side stand.
I searched for and acquired another stand this time from a K1100 as popular opinion and rumour say they are stronger.

The stand has been stripped back to bare metal and painted with engine enamel. The last picture is me filling the tube with the paint to stop internal corrosion.
