Well quite a lot has happened since my last post.

I stopped off at Grampian in Bootle for some advice on the barrels and I was hoping to obtain some pistons.. I took the barrels out of the box and he looked at them, oh I'm my 40 years I've never seen one of those barrels! I knew this wasn't going to go good...
Long story short, he advised a replate but a little more annoying was they do not stock nor can order pistons..

So back to some updates..

Some bits back from Aqua blasting









Also gave the radiator a sanding and a light coat of black





Calipers rebuild and painted, just waiting for my new braided lines to arrive.





Master cylinder rebuilt



Then the reeds were rebuilt with a  set I sourced from Germany..









Them something very big finally happened!





Even thought I'm piston-less I couldn't resist! Reed blocks also fitted.







Sorted most of the wiring loom and got it connected up to a spare battery..







And finally a shot of it with the tank (pre-paint) in place..



Next on the to-do list is get my barrels replated, new pistons, a few PV oil seals and thats about all the top end looked after.

The electrics appears to work okay..
Neutral light functioning OK
Oil level switch OK
Front lights OK
Rear lights OK
Horn OK
PV motor operating when I turn the IGN on
Indicators are not flashing

Carbs are cleaned and rebuilt, I don't have any photos of them at the moment. I think thats about all for this weekend! Hopefully I'll be kicking her over soon and filling the garage with some lovely burnt stroker oil  :D

Hi,

Looking good.
Is the finish on the yokes just obtained by the aqua blasting or have you had them coated.

Cheers.

Thanks UKPMIL,

The finish on the yokes, fork legs, engine casings and any other bare alloy are just from aqua blasting, http://www.fjaquablasting.co.uk/, I've also had the master cylinder & various brackets done, top bloke and excellent work from Mark. He has about 4/5 RD350's in his workshop and has run the bare alloy forks/yokes for a number of years without any further corrosion to the alloy. It's not like our bikes are left out in road salts over the winter so I assume it's okay to leave an unpainted alloy finish.. Well I assume time will tell in my situation!

The first time I visited him he had a 3MA, looked original and untouched in the speed block colours, if I remember correctly had circa 3000kms on the clock.. Anyone on here?

Cheers for the comments everyone, it's nice to see some positive feedback!

Not a huge amount to report, more ballache from Wemoto as they sent me the incorrect master cylinder rebuild kit..
I've fitted the new grips, a few fixings for the rear brake, spring/circlips etc..
Battery box is fitted

Also, got an email today from The Tuning Works, barrels and pistons arrived OK Hopefully in about two weeks time I'll have the replated barrels returned and the top end can be rebuilt and then it's time for the start-up!

I've a few questions..

I got a replacement relay from Fleabay as my indicators were not flashing..
Connected up the relay and now when I turn on the indicators either LHS or RHS, the clock light dimly flashes and which ever indicator I have selected flashes at about 70% brightness and the opposite indicator flashes at about 30% illumination.. Any ideas whats going on with the front indicators??

Also the rears are not working, I assume grounding issue which I'll have to take a look at.

Just a few photos..

New fixings on the calipers - makes all the difference..





Carbs cleaned and rebuilt








That's all for today.

I know it's been a long time since I posted but a house move and & as I told the missus "a lick of paint" turned out top be stripping plaster off most of the interior of the house back to brick, re-wiring seen as it's back to brick etc etc..

No back to the 3MA, yesterday evening I finally managed to get some time in the new garage. Barrels have been plated by the tuning works, very good service and the finished product looks amazing!





All new PV seals fitted, studs back in the barrels and managed to get both PV assys rotating smoothly with little resistance.







I know it's only  a small update but it's one step closer to getting complete which I cant't wait for the summer

That's going to be one clean bike!

Just one small point, the pv seals face the other way, so the castellated side faces outwards. Thought I better mention that before you bolt the whole lot together!

  :o ;D

Oops, It's all loosely assembled, I did wonder this last night when I was assembling which orientation the seals should fit, maybe a little too much enthusiasm since it was the fist time in ages I got to get back to work on her. Thank you very much for pointing it out to me!

no worries.. and oh, you may want to fit some larger main jets, even if everything is stock. I would plump for 200's, but perhaps other people will have a better idea, it's been about 20years since I did much with stock 3MA's.  :o

Thanks for the advice Martin, I'm planning on changing the main jets to better suit..

Although the 3MA may slow again due to the most recent purchase.. DRZ400SM, 440 Big Bore Kit, Yoshi system and a few other little bits;

Hello,

A little update, well more of a question...
I'm putting the rings onto my Wossner pistons, all 4 rings appear to be the same part number and appear to be symmetrical, the only identifier i can find on the rings is the letter 'n" near the ring gap.

Should the N face up to the crown or down towards the skirt?

Image attached of the ring, also the pins where the ring gap sits in the piston appear to be central to the slot in the piston therefore I'm thinking the ring orientation does not matter???

Cheers.

Usually any markings face upwards. I can't say for sure about Wossner rings, but they look the same as Wiseco rings. Wiseco rings are flat so (as far as I know) it shouldn't matter which way up they are fitted (although I always fit them with markings upwards ;D ). However, make sure they are not keystone rings (which should only be fitted one way).

Regards,
James
