A ZPF EFCO popped up on eBay yesterday at a reasonable price and I had to have it. It looks complete from the pictures which is a result for something this old.
In the description it said its been sat in his shed unused for 20 years and cost him lots of money when it was new. He says it turns over freely but hasn't tried to start it which is a good thing.

This will be a full rebuild shelf bike that may get the occasional run.

I looked over the pictures for about 5 seconds and it all looked to be there so hit the but it now, couldn't have somebody else beating me to another one could I Tony :)
Did you manage to find an engine parts supplier or sort your clutch issue?

:laughs: Yeah - don't blame you, I would have had that one too in a heartbeat (even though there just aren't enough hours in the day to get any of my other projects finished lol)!:D

Your patience has most definitely paid off there - that one is the most complete unabused example I've seen for sale for a long-long time. Awesome spot and I'm glad it was you that got it (hate to think a chav would have got it/thrashed it round an industrial estate until the clutch stripped and then threw it in the skip!)

As for the clutch issue - I managed to convince Cutts to sell me some parts from his spare one a while ago (including a clutch shoe from memory) - so think I have one and a half complete Efco clutches now for an Efco engine - but got 2 Efco engines, so if you find a supplier of new ones pleeeeaasssee let me know :yes:

There is actually some material left on the shoes although its about as thin as a Rizla paper.
Been searching the internet and can't find anywhere locally that relines brakes or clutches, and can't find anything relating to the efco engine. Is it actually called an efco engine or is that just the ZPF model name?

Found time yesterday to get out and start to strip the bike. Its a pile of bits now except the rear wheel as Im struggling to get the spindle out. It's been laid up for twenty years apparently. I tried the gentle approach of lube it and wiggle it but that didn't work so took the persuader out of the toolbox and "gently" tapped it, moved about 2 inches so lubed it a bit more and left it for another night.

Correct me if I'm wrong but I think these bikes are late 80's early 90's so was debating whether to keep the paint scheme to that era of race bikes so if anybody has any ideas do let me know

I also struggled to get the spindles out of mine - Tony had the best one and the other that I kept for my bike now has damaged threads!!! I put it in a drill and filed the spindle until it was a better fit and greased it as you say. It still doesn't slide in "ooh eerr missus!" like it should. Maybe I should have filed some more off but I was damaging the threads by clamping it in the drill chuck... :-(

So seeing as mine has a few of the graphics left I know it was a cagiva rep so I'll be doing it back to that with a few little differences.
Not done much as everyone round here wants an absolute fortune for everything like chrome or paint. So iv cleaned up the engine and wheels so far. Fitted bearings,disc and sprocket since the pic.

Unfortunately iv just got a standard 40, would really like the exhaust though. I messaged Ferrino incase his was meant to have the front brake be he said it was def a Blata fork. Shame it doesn't show the front brake in the pics.

Send me your email and If it can be scanned I'll send you a copy.

This is the bike it's based on I think. Thought there was too much red though that's why I done the wheels black

I had the Marlboro Yamaha from Tony Hemming in 1995, we made so many modification to these, apart from the engine, mine was the 40GP, i later added the front brake kit, special fork leg, and you had to drill and tap the front wheel. The calipers were rubbish.

I sold one of these exhaust a few years back to a german guy who was restoring a bike.

Bullit
20-10-2014, 07:21 PM
I don't suppose you've got another lying around by any chance?

My front wheel has the drilling marks cast into it ready to be drilled.

I'm not sure if mine has had a different engine fitted as there is another 4 holes drilled into the base where the engine mounts.

Internet is down at home and I'm having to try and do stuff from my teeny phone screen until its sorted lol.

Sadly I don't have a spare Efco race pipe unfortunately, it only came with the one it has fitted :(

The bike is all back together now and finally running right after fighting with an air leak issue on the carb. Also raised the jetting upto a 62 as it didn't run that great on the 52 that was in there Prob cause it's bloody freezing outside.

Stuck some 6.5" wheels on it as I don't think the original tyres are gona have any grip left in them after 20years in a shed. Still haven't managed to find or stockist that can supply parts for this engine.

New clutch shoes are fitted but it cuts in really early and is very boggy. Would like to do the pini clutch upgrade but can't work out how the done it back in the day, all the posts say you just need an adapter plate but the original clutch plate is threaded.

I tried to clear my inbox......i think there is some problem with the saved messages that i cant delete.

What are your questions?

The clutch spring are not great they open at low revs way below where you need them, you can shorten the springs and use two to stop the clutch biting so early. The other racers trick was to find old clutch shoes that had virtually no friction material on, gave another few hundred revs.



Regarding jetting, they are very fussy, there are two different types of SHA 14/14 carbs, you need to find the special with with the additional emulsion tube holes :)

Looking at the 2 plastic rollers for the chain, you need a nice spring between the two which acts a tensioner,they dont like the chain being tight. The other major thing is to make the sprockets line up really accurately.

How did you used to mount the bzm clutches onto the crank as its threaded not key wayed?? Iv managed to source some springs from a 1/5 rc car that uses a similar clutch. The springs are the same length as what's in there already but come in 3 different strengths, 6000rpm, 7000rpm & 8000rpm. I know that may not transfer over exactly to the efco but iv gone for the strongest ones to start with and am just waiting for them to be delivered.

Iv already done away with that carb and replaced with 70 card that has the two holes as found that used to cause me issues at part throttle when I first started in my baby Blata


I also found a post regarding adjusting the port timing. If I can find another barrel I'd like to do this. Do you know how much they need to be raised/lowered??
Don't suppose you've got a spare race pipe as mine hasn't got it.

Thanks. Dan

I'm actually back in the uk for 2 days, i will go and check the EFCO and see if i can take some pics of the BZM clutch, i cant recall off the top of my head we had to make spacers and use the 78mm BZM drum. I'm sure i have clutch spacer plates i made somewhere.

I have a spare engine somewhere, it was tuned by Pete Davies, Chaz's dad back in the mid 90's. I have some basic port change maps i need to dig them out. The deck can be lowered to raise compression, but not that much as you will have problems with the crank bearings.


The engine i have is a reaper tuned engine, its very very good tune.

The race pipe i sold to a guy from Germany 6 or 7 years ago. Since Tony Hemming sold the business and they seems to have moved, the guy who was left was called Dave was the warehouse storeman i have no idea if he is still there, i managed to get some pistons and other parts off him.

We should get all these historic bikes out and have a go on them sometime!

Cheers Ian

That would be great if you could get some as I have a spare clutch and 78mm housing and reckon that would make such an improvement. I can't even ride it at the moment coz it comes in so low. Worse than a CAG lol.

Ooh a port map :) Bet they scream when set up right as it runs a revs out sweet on the stand.

Iv tried getting Andy and Ferrino to part with thier pipes but funnily enough they don't want to.

Yer def have to all get out for an industrial race. Maybe swindon one Sunday eve when your about.

you can see on the clutch that there is a welded nut on the polini clutch to attach it to the EFCO crank. I think my other bike was a different arrangement i think the clutch arm of the efco was drilled and the polini clutch bolted on to it. The spacer pate is tricky and the dimensions need to be spot on.

I didn't have much time and the other bike is buried in my parents garage loft, but you can get the idea. I found a spare engine and another top end.

The clutch makes a huge difference, the motor should spin past 13,500 with a good port :) i haven't ridden it in 10 years but it was faster than most 4.2hp polini's.

Thanks a lot for the pics. That looks like a 910 seat grafted onto the efco tank unit to me?

That clutch mounting is nice and simple, just a threaded sleeve welded into the backing plate. The spacer looks a bit of a pain to make, might not be able to do that on the bench in the shed lol.
I like what you done with the third spring on the clutch.

I'm looking forward to actually riding it. How comes you've not ridden in 10years?

The spacer need a machine shop to make it. As you need the inner holes to mount to the EFCO engine and the outer holes to the polini clutch housing. I had mine made out if aircraft grade alloy😬

The clutch with 3 springs was an idea before swapping to the polini clutch. I was getting left behind out of the slow corners.

I have an all original set of bodywork as well, the race version is a mess but you can move around more on it that the original EFCO.

I raced from 1992 until 2005. Poduction class, supers, 4.2 hp and the EFCO in the original format of standard and then the Paul Godward modified EFCO class.

I got fed up with it, but could part with the 2 EFCO bikes.
