Ron Posted June 16, 2021 Share Posted June 16, 2021 You are right Lex! I remember looking it all up for Martyn Streeter ages ago and it's an ME thread which Martyn had never heard of.....Will have to look it up again and save it.

welbike Posted June 16, 2021 Share Posted June 16, 2021 Yes, let me know the results please! Lex Quote Link to comment Share on other sites More sharing options...
Ron Posted June 16, 2021 Share Posted June 16, 2021 (edited) I think this is right, but I'll check with a thread gauge later. The adjusters are 7/32 x 40 ME (model engineers) The throttle stop screw is also odd....1BA from memory.

Ron Posted June 16, 2021 Share Posted June 16, 2021 Stupidly this morning I picked up a small ordinary cable adjuster from my Amal draw. I've just double checked a carb top adjuster and I can confirm 7/32" x 40 tpi ME. Ron Quote Link to comment Share on other sites More sharing options...

flyingfleasteve Posted June 29, 2021 Author Share Posted June 29, 2021 With a spare day I managed to inch forward with the build. The lightly restored saddle cover is now fitted and most cables now made/laid include the speedo connections. Finally I have found a lower timing sprocket and chain which is slowly allowing me to finish the engine. I shall shortly be looking to make/connect the last of the oil lines, including the rocker feed. It appears that all the oil/fuel pipe connections are BSP threads of various sizes, does that sound correct! 2 Quote Link to comment Share on other sites More sharing options...
welbike Posted July 4, 2021 Share Posted July 4, 2021 Something I didn't know, is that some G3WO's had black speedo's, could that be the civvy trip speedo's that were in one contract? Found a nice NOS ammeter ring the other day. Cheers, Lex Quote Link to comment Share on other sites More sharing options...
Ron Posted July 4, 2021 Share Posted July 4, 2021 Hi Steve. All our panel G3's should have a trip meter and it should be Khaki with a dull chrome bezel. I suspect the center bike in the above picture with a black speedo has probably had a replacement unit. Ron Quote Link to comment Share on other sites More sharing options...

I believe that post came from Lex 😉 I have fitted a speedo with trip meter to my project, at the time I was unsure of colour so painted it Khaki.

Ron Posted July 5, 2021 Share Posted July 5, 2021 Very sorry Steve! My mistake! It's Lex who's making up things😆 Ron Quote Link to comment Share on other sites More sharing options...
welbike Posted July 5, 2021 Share Posted July 5, 2021 (edited) Ha! I'm merely quoting John Tinley, as I was mentioning the black speedo on a post on Andrew Helmsley's G3WO, at FB conversation, but I will delve into the trip thing. there is only one black speedo in my picture though, so maybe John has another picture?

Ron Posted July 5, 2021 Share Posted July 5, 2021 The speedo with trip is listed for my contract and I can only make out one black speedo in that picture, second bike from left. 1 Quote Link to comment Share on other sites More sharing options...
welbike Posted July 5, 2021 Share Posted July 5, 2021 (edited) Yes, just changed my text!! but that doesn't mean all panel tanks had a trip speedo? Have I opened up a can of worms now? looking through the hundreds of G3WO pictures I see more and more black speedo's and in one of them it looks like the little knob for resetting the trip is visible, see below.

Ron Posted July 5, 2021 Share Posted July 5, 2021 The extract from the parts list that I posted is for contract C5247 (mine) I have no idea about other contracts. Ron Quote Link to comment Share on other sites More sharing options...
welbike Posted July 5, 2021 Share Posted July 5, 2021 Ok, I'll check later (bought another 2 wheeled apliance, that I have to pick up this afternoon!), but going through the pictures, I'd say 10-15% of the speedo's on G3WO's are gloss black, also on a better copy of my first picture the speedo's are darker than the KG3 of the bikes.

flyingfleasteve Posted July 9, 2021 Author Share Posted July 9, 2021 Baby steps forward, more oil lines made and fitted. I have adopted the earlier single piece rocker oil feed……should probably paint it silver now 🤔 We will soon be on that race track Ron!

Ron Posted July 9, 2021 Share Posted July 9, 2021 Well I was getting worried Steve. I was thinking that you might have joined a Welsh mail voice choir or something? BTW, officially there should be a rubber connector in the rocker pipe. #36-G8-E284. I guess because the pipe is strapped to the front tube, they thought a flexi part in the line is necessary? All the best. Ron Quote Link to comment Share on other sites More sharing options...
flyingfleasteve Posted July 20, 2021 Author Share Posted July 20, 2021 Sorry all for the radio silence, the last month has been super busy with work etc… Ron I was of under the impression that some of the early panel tanks Matchless G3’s had a single piece rocker oil feed pipe, but I may be totally wrong!🙈 With a few spare hours I have picked up the spanner’s again to get some more tasks completed on the G3. The timing side of the engine is now completed with the drive side just a little way behind with the clutch now finally fitted with the correct bearing race. The primary casing band is a pig of a job to get right and what makes its harder is I think my band is to narrow. With most of the engine together I have now started to look at the exhaust, more specifically the fitting of it, being reproduction I wanted to ensure it fits correctly before making the brackets and painting it all up. With most of the time consuming jobs now completed it won’t be long until I start on restoring the tank. That then paves the way to finish the electrics and enjoy! 1 Quote Link to comment Share on other sites More sharing options...
welbike Posted July 20, 2021 Share Posted July 20, 2021 Looking good Steve! I have found some one piece oil lines in the past, but the parts lists all mention a rubber piece, so not sure what happened there. Cheers, Lex Quote Link to comment Share on other sites More sharing options...
flyingfleasteve Posted July 20, 2021 Author Share Posted July 20, 2021 Thanks Lex! I shall keep the oil feed pipe one piece for now it’s easy enough to cut it if/when required. I cant quiet believe how much heavy the G3 is starting to feel in comparison to the G3L……The G3 is a lovely looking bike though! I’ve decided to replace the later period alloy push rods with the period steel ones so I cannot get the rocker box on properly for the next few days so a little bit of downtime before forging forwards again.

flyingfleasteve Posted July 27, 2021 Author Share Posted July 27, 2021 Another successful day with the primary side of the engine now completed including the rear break lever components now on. lots of fettling, as nothing would fit quite right but still a leap further forward. Next step, push rods in and rocker cover bolted down….. Quote Link to comment Share on other sites More sharing options...
flyingfleasteve Posted August 11, 2021 Author Share Posted August 11, 2021 Hi All, sorry for the delay in the update…….so a few backwards steps needed. Unfortunately I did not take enough links out of the primary chain so when I put it all together the gearbox shaft was rubbing on the inner chain case. 🙈 I have stripped it down to rectify my error but now the rear wheel drive chain is two short and I have lost the links I removed! Whilst I try and source some new links for the chain the correct exhaust clamp has finally arrived so I can get the exhaust system on. Currently most of my time has now been spent on prepping the petrol tank which is slowly coming together……. 1 Quote Link to comment Share on other sites More sharing options...
welbike Posted August 11, 2021 Share Posted August 11, 2021 Good work! but I had hoped to never see that clamp again! you will find it's completely bodged, and needs welding and machining, I had it in the US, and no Idea where it went after I found some NOS clamps.
