Title: Timing advance
Post by: Laverdaroo on May 09, 2023, 09:04:37 PM

Evening all, working on the 400 tonight getting it ready for the road and knowing I had to set the timing etc I set about it.

I’m having a real faff getting the test light to come on anytime before the T mark on rear plate, it simply won’t advance anymore. Any ideas?
Valves, done, cam chain, done. Points, done, just can’t get it timed. Any thoughts on my stupidity?

 The test light only just lights up here and I’m on full advance with no room left on the sliders……..

Disregard all of this post, I’m following the wrong marks like a div!

Apologies, as you were!

Sitting front of it now and I still can’t get me suede round it. The light just flickers on at that point but nowhere else will it light up over the full adjustment. Come on, put me out my misery Ken, there’s a good man.

Are you saying it times on 1-4 but won't on 2-3?

If so reduce the point gap.

Sorry Roo I thought the static timing was the easy  bit just follow the manual have you got it so the points with the blue wires are to the coil that is connected to 1&4?😁😁😁

Title: Re: Timing advance

Roo your setting the 1-4 points in that pic, the crank turns clockwise, so by turning the backplate clockwise you are delaying the timing, turn the plate the other way and check again.

The buggers been running

Just bring a real pig but just whipped 1-4 points off and although they might have been set at the front they very much weren’t at the back

That’s not good. Fiddling, will report back….(https://uploads.tapatalk-cdn.com/20230509/422a6fa39844287dc3e083474bceaad1.jpg)

They were bent well out of shape so flexed em back to a right angle and it’s squared the faces back together. I’ll set the gaps again and have another bash…….(https://uploads.tapatalk-cdn.com/20230509/4cae42f91c328086134ec932eb16c25d.jpg)

Bent that back round, sorted it straight away. God knows how that got knackered light that but straightening it has sorted it, happy days. Attention to detail wins against head scratching wins again

Because it's well known that if you don't use TEC points there is a very good chance you'll struggle to get the timing to set correctly, especially on 2-3 as you use up all the adjustment doing 1-4.

Cheap budget points have the pivot pin arrangement skimped on and that's most likely why they twisted out of shape.

BTW I found that dwell meter, I'll take it up to Nigels and test it against my other, so long as both work you can have it.

Bloody marvellous on both points fella’s. Thankyou. The plate is deffo TEC and they came on it so had no reason to not think they were legit. You can tell by just looking can you?

Good info

If the points are genuine TEC ones they'll be stamped and the back plate has a sort of chequerplate design imprinted on it.

BTW genuine TEC points are mega expensive now. I sold a pair to Matt for his bike a few weeks ago.

Pics off DS website.

TEC https://www.davidsilverspares.co.uk/graphics/parts/30204300154_large.jpg  £36

Copy https://www.davidsilverspares.co.uk/graphics/parts/30204300154P_large.jpg £9

Compare the way the contact plate is attached to the moving arm, the bushing on the pivot pin is not as good as the TEC ones.. Note the design on the plate.

Yep, exactly like that.

Title: Re: Timing advance
Post by: Laverdaroo on May 10, 2023, 02:25:21 AM

They must have had a knock and I hadn’t realised. The gap I was setting was at the front where the back side was miles away causing the issue.

Gained about 8mm of  adjustment on the back plate slide and two n three needed a bit of a shuffle to set but reasonably happy. I’ll see what happens when I fire her up and point the strobe at it. I think it’ll be out but if I can get it better I’ll have a go.

I just managed to source 4 pairs of 1-4 points and 2 pairs of 2-3 points. Australia and Canada. Still cheaper than buying from DS.

Good man, theyre pretty extortionate from DSS arent they? Bryan says he has a few sets lurking so I'll rplace them when I get a chace and get up there.Possibly when the jaw has gone down a bit, still quite swollen at the min.

Title: Re: Timing advance
Post by: Oddjob on May 10, 2023, 05:09:17 PM

They are only going to get dearer Roo, buy them now and store them is my advise. Why do you think I have so many parts in the loft? thinking ahead all the time. If I see any part going dirt cheap I'll buy it and store it, some I sell for what I paid and some I make a decent profit on, depends on who I'm selling to. Even DS hasn't got any 1-4 genuine TEC points now.

Was trawling the web last night looking at the amount of points that sellers claim are genuine but ain't is worrying, look at how the contact points are attached to the plate, genuine TEC have a sort of collar around the point plus of course that pattern on the plate itself, no collar, no pattern, it ain't TEC then.

TBH it makes buying the Hondaman system more and more attractive, you need to replace points far far less with that piece of kit fitted. Or you could always fit electronic but if they fail or get damaged your stranded, I once dropped the 500 when I was 17 and it slid across the road, mounted the pavement and then re-entered the road. When I got to it the points cover was just mangled into the points, the advance/retard unit bolt was bent, I still rode the bike home on 2 cylinders as one set of points was completely trashed, you can't do that with electronic. Electronic is fine so long as it works, you can't bodge it though, it either works or you walk.

I found 2 NOS condensers the other week, snapped those bad boys up as soon as I saw them.

Title: Re: Timing advance
Post by: Laverdaroo on May 10, 2023, 06:15:07 PM

I’ve a spare condenser but only one but several plates to cannibalise but sadly no points. I’m hanging fire to fit the Hondaman set up until it’s run in then I can sort things a bit easier and leSs to go through should summut go TU.

What do you need for a set Bryan?
