solid state teaser

The electro-mechanical voltage regulator on my Ariel was terminally ill, so I decided to fit an elderly 6 volt positive earth solid state unit of "Podtronics" make that I had salvaged from a BSA undergoing work in progress. It is worthwhile mentioning that this was bolted to the inside of ...

Chrome plating

If you require surface finishing and you are in the north east (although a postal service may be possible) try the firm detailed below. I have just picked up a pair of silencers, a pair of saddle springs and a pair of fork top nuts that have been stripped, polished and re chromed for my 4g. A really...

Re: Burman kickstart lever

I am quite interested in the outcome of this enquiry. I have just completed the rebuild of my 1947 rigid/teles 4g and getting the right hand exhaust system to clear both the rear stand and the exhaust, can only be achieved by the silencer outlets not being equi-distant from the rear wheel. Not by mu...

Re: Twine seal at tele fork slider/oilseal holder

PTFE tape is good, using a lot more than you might expect, wound in the direction of tightening on both threads and the recess below. Even better is to twist the PTFE tape into a thick "twine" and use this as you would ordinary twine, but also smear the threads generously with a putty like...

Re: Cover girl!

The quietness of the old "noddy bikes" was always a problem to me and a pal in our very early teens in the period 1960-62, wheeling our field bike over the road to ride on some rough parkland. Our answer to PC Burns after he had sneaked up on us, was that we did not need licences or insura...

Re: Poor quality pattern spares

I have communicated with Draganfly (which I should have done at the outset) and Roger confirms that the stock of the "sump plates" do need modifying. Aparently most are sold for use as the timing side bearing covers (not needing the recess) and made in house. The stock will be re-machined ...

Re: Poor quality pattern spares

Thanks John, I take your point, but to be totally honest I am fed up with some of the rubbish parts that have come my way restoring other makes and also to many of my aquaintances (and in seemingly in increasing quantities and varieties). Only 2 weeks ago I was sent a speedo bezel with no thread (no...

Poor quality pattern spares

During final assembly of my recently rebuilt 4G, on fitting the crankcase inspection plug - a final nip with a spanner left the ring of threads in the crankcase and the cap in my hands. No problem as the threads came out easily and a new billet cap as opposed to the original cast one was obtained fr...

Thanks to this forum and Bruce Longman, I am pleased to report that my iron 4g now runs and although not yet used under load, has consumed a few pints of petrol over a number of runnings and seems to be freeing up nicely. I used the =+ 0.060 AE16179 pistons previously mentioned in front bores with 0...
