Finished the last bits and pieces.

Made new brackets and fitted the new Tailpiece MK3 with the light strip sunk into the tail. Looks much better I think. I also used rubber well nuts and allen bolts for a better looking and stronger fit.

Fitted the replacement Side Stand. Or as DJewen called it the Suicide stand. What a mad idea a stand that springs back up and is impossible to put down while sitting on the bike. I find if you get off, put it down with your boot you can lower the bike onto it. Never seen one like this before though  :dunno.   

Finally Calibrated the speedo. I took the bike out with a GPS program on my mobile phone and it was within 2 MPH. GPS show 40 Speedo said 38 No changes required.  The cheapo Chinese speedo works great. The indicator lights are clear and bright and its accurate. I can say first impressions are that it was a bargain at £21.00 Sterling. I will update on its long term reliability.

A few more photos. Since I finished I painted the exhaust and the Radiator grill black and fitted new tyres. I split the use between the BMW and my Triumph and I am loving it. She continues to run like a dream with no Issues. Itís a great bike 😀.

Hey People. Just thought I would share the cost of my Build. Being Anal I kept a spread sheet.

That's a skunk face cluster and theres already a Skunk head inside the helmet. Or is that a helmet inside the skunk head.

Morning folks

Been a long time since I posted here. Bikes still going well but I have a list of things I need to attend to.

1)  Sort out the air balance. Still runs rich. The plugs need regular cleaning.

2)  The Fan is not coming on. Possibly its not getting hot enough but I suspect either the relay or sensor.

3)  Bloody Starter motor. Had to jump start it a few times. Just found out about the reverse sprag thing. But its working again at the moment.

4)  Fuel light, Not really important as I have a working gauge.

Still looks good though

Had some time yesterday.

1)  Sort out the air balance. Still runs rich. The plugs need regular cleaning.

Carried out a throttle body Balance using a set of vacuum gauges. And then tried the lean drop method to try to clean the CO2 mix. Seems to be running much smoother and cleaner. The adjusted is a fiddly little sucker to get to with my oversized mitts. It was really out a long way so I expect it to be better. I will run it for a while and chack for further soot.   

3)  Bloody Starter motor. Had to jump start it a few times. Just found out about the reverse sprag thing. But its working again at the moment.

Tried the reverse sprag cleaning thing a few times and it starts fine. I'm not actually sure if it isn't battery/alternator related as when it stopped working I lost the indicators lights and horn. I always leave my bikes on trickle chargers so it's always OK when I first start and leave but tends to fail later. Further investigation to follow.

4)  Fuel light, Not really important as I have a working gauge.

Had a good day. The Beemer and my Thruxton passed their NOT tests today. The tester failed my K on throttle return sticky until I showed him the adjuster screw.

Still I in love💘

Euromotoelectrics sells a starter service kit that includes replacement brushes. Not much money and not a difficult job once you master pulling the starter motor. Worn starter motor brushes can lead to oddball electric issues, so this is totally worth doing.

As far as the sprag clutch, run the proper motor oil and that shouldn't be a problem.

Keep enjoying your K!

I. Already stripped the starter and found the brushes to be ok. However the copper contacts were really cruddy and scortched. 20 minutes with a wire brush did the job. I've had no starter trouble since 😁
