Enfield's Rebuild

[EvilEnfield]

Hello Everyone, I've been busy moving house, but I'm nearly settled now and as soon as they install my internet I'll be doing my own rebuild thread.

Before I moved down here I won a tank off ebay, turns out the bloke is a very nice chap who is just down the road and I've got a powder coated frame off him as well, so I figured I may as well give it a go.

I plan to just clean up and re use whatever parts I can, cafe the tail end but make it removable so the original tail can just bolt back on, with a slightly narrower bit of tubular steel to feed into the frame.

I am also going to try and reduce the wiring and run it through the frame somehow.

Maybe rearsets, and if I get hold of some cheap enough rearsets then I may as well get some clubmans or clip ons, but my main priority will be getting it to run properly.

I'm sure I'll be on here looking for advice in no time, I can't wait now.

You've gone native already - Kernow in your location box (the furriners won't know where that is). Just watch the weight with all those cream teas!

 

[EvilEnfield]

Yeah I've gone native, even got a bit of an accent, you have to, if they find out I'm an emmet I'll likely wake up in a wicker man! I'm not too worried about the weight, I'm pretty sure I was at maximum capacity before, I've lost about a stone already with all these hills, maybe a bit of piskie magic too.

 

[EvilEnfield]

Right, firstly apologies, it turns out I'm really crap at remembering to take pictures, I promise I'll take some first thing tomorrow.

I have made quite a bit of progress, the old frame is mostly stripped, I'm stripping the bare minimum as I don't have much space to work,.

To get the engine out I used the tip it on the side method, but it was a real struggle lifting the frame off with so much still attached, to get it in the new frame was easy, I just put the bottom rails on 2X4s up on their sides, straddled the frame and lifted it in, oh, and removed the rocker cover. I know I should really have got it rolling first but I thought the extra couple of inches lifting might hinder me.

I'll put the swingarm and forks on tomorrow, providing I can strip these marzocchis down for a cleanup, any tips on the rope trick anyone? I'm having trouble fitting any down the sides far enough, They are really stiff and on their highest setting and I can't even lower them.

Rear master cylinder refurbed, harness stripped down so I can split it evenly through the frame, and it is looking quite possible at the moment, but I am prepared for failure! chain cleaned, front forks already refurbed etc.

Also does anyone know where to get the clamp for the front master cylinder with the hole for the wing mirror?

More updates and pictures tomorrow.

Sneaky peek of the cowl moulded off the back of the tank, bit of filler and it will be sweet. Got two small flat round lights to go in the back.

Right, here we go, I'll put up the pathetic amount of pictures I managed to get.

Odelay and the boxes of parts, Thanks Boomer.

Wish I'd cleaned the engine up.

Seat is getting there.

I cut out shapes from recycled upholstery wadding for the bits that I wanted raised, kind of an arse crack shape, raised slightly at the back and front, two layers of that and then about 8 more layers to smooth it out and add plenty of cushion and height (I like style, but comfort is as important) then a leyer of upholstery foam and vinyl over it. I'll try harder to take more detailed pictures of the rest of the process, it's hard with the rain and children.

A few tricks here might work. http://www.thegsresources.com/_forum/showthread.php?t=187335

Hello everyone, took the rocker cover off to adjust my clearances today, dropped a bolt down the slot where the timing chain is while I was looking for it I noticed my exhaust cams are worn, so a couple of questions today.

Is the bolt I dropped likely to have fallen straight down into the sump or are there places down there for it to get lodged out of sight?

How worn are my cams, and is it a result of poor maintenance or just general wear and tear? Also is there a higher lift cam that will bolt straight in, I'd rather upgrade if there's an option rather than just replace.

There seems to be no wear at all on the intake side, but the followers seem to be very close to the exact width as the cam, should I be able to feel wear on the edges if there is any?

Thanks in advance.

You'll need to find a better potato to take photos with - you're almost as bad as me at close ups! I can't tell from your piccies I'm afraid but if it's just that brown line they all have that.

The bolt stands a good chance of finding it's way down to the sump but it could have got caught. I would drop the sump and poke around with a bit of wire if it doesn't come out - you'll stand a decent chance of dislodging it.

I would leave the stock cams on there; you'll pay a lot for anything performance (if you can find anything). Plus the 750 is already a good free revving bike anyway.

 

[EvilEnfield]

Cheers HH, that brown line is a ridge. I really do need a better potato, this one is dead soft, might help if I wiped the grease and pocket fluff off the lens though.

 

[hampshirehog]

If you can feel a ridge then that would suggest that it would be better replaced. Poor maintenance (lack of oil changes / crap oil etc) would be a likely cause.

 

[EvilEnfield]

No joy on that bolt, I think it's wedged in the chain at the bottom, I tried wiggling on the crankshaft but it won't budge. Anyone got any more tips before I start disassembling?

 

[hampshirehog]

Can you see it?

 

[EvilEnfield]

No I can't see it, I've had a torch down there, underneath it, magnet, coat hanger, fingers. It is winding me up, why is it always the easy jobs?

 

[hampshirehog]

Cams out and tensioner off then I think. Wiggle the chain around and see what happens. PITA .

 

[EvilEnfield]

Yeah I thought so. I think I'll leave it for a week or so, just until I calm down.

 

[hampshirehog]

Alternatively tip the whole bike upside down - somebody did it on here and it worked.

Or try flushing it out with some derv (but throw some oil down the bottom soon after flushing to save the bearings from drying out.

 

[EvilEnfield]

Funny you should say that, I was just thinking it would look better upside down, albeit at the bottom of the hill and on fire. I don't think it will flush, I can't turn the crankshaft in either direction, it must be perfectly wedged somewhere in the bottom, what do you think would give first if I gave it some welly on the crankshaft? Also is it a straight path out of one of the hole on the bottom if it does dislodge? I can't see or feel how it would drop down.

80-=81 750's are known for tearing up the ex cams. Has to do with poor oil flow. you should drop the oil pan and shim the oil pressure relief spring. Use synthetic oil and change it often

 

[hampshirehog]

I think if you can free it from whatever is keeping it from getting to the bottom of the crankcase then it will settle out of the sump with the plate off. I've rescued a few GS(X)s where things have gone down the cam tunnel and they have come out fairly easily with a bit of jiggery-pokery. However, that is all on GSs with roller cranks - things might be tighter down below with plain cranks, I'm not sure.
