Pre-65 Bikes

Hi all any advise on fitting the later type primary inner and outer cases to a 32A ? Looking at it it seems you have to trim the crank case up with a dremel ? Got to be better than the massive rugby ball type case that's on there !! Would this make it in eligible for the Scottish p65 ? Your thoughts please Cheers

Whats the correct plug for a villiers 32a engine?

Hi: What is the best timing for a Villiers 37A? I have to fit a new electronic ignition for my Greeves and not sure about it. Thanks for the help.

Hi All I'm going through the Villiers 37A motor on my Cheetah trials bike. I have a couple of queries : 1) There seems to be no gasket between the armature plate and the crankcase. I can't see one on the Villiers parts manual and repair manual either. There just was a smear of red hermatite gasket sealer on the mating halves when I took them apart. What is the correct way to re-assemble them? 2) There is a second coil in the left hand side of the armature plate which I presume is a lighting coil. The ignition coil is on the right hand side. Can someone please confirm this. 3) The gearbox and primary chaincase have oil filler and level indicator screws. Will SAE 30 oi…

Hi people , Happy new year . Having trouble with a villiers gear box i'm assembling , 4 speed 9e to 37a type . I have a lot of in and out play on the main shaft , all looks good comparing with a parts book , but should it have anything between the pressure washer and high gear ?? this would take up the play ..Any advise

I have a 6E 197cc Villiers engine and I'm looking to increase usable power. One way is to use a 1H piston and bore the barrel out to 225cc. I managed to get hold of a standard 1H piston, not an easy item to find. My dilema is the piston weight and increased imbalance of the crank. The old standard 197cc Villiers piston weighs 250g. I rebored it to +20th for a Hepolite dykes ring piston when I got the bike and this piston weighs 275g. The 1H Villiers piston I have weighs 300g! The thought of an extra 2oz/50g flying round at 4000rpm is a bit worrying. Even with the Hepolite piston, which I now assume to be a racing piston for Karting, there is quite a bit of vibrati…

Hi there Following on from my previous topic on gearbox sprocket.... I got a 13T sprocket off Villiers services to replace my 17T with and at the same time decided to change the cork clutch plates for ferrodo. Sent my plates away for exchange, everything arrived - all good..... Disassembly, went OK, everything removed etc fitted 13T gearbox sprocket Reassembly ..... problem.... There is now about 3-4mm lateral play on the splined shaft that the clutch fits on, therefore when the clutch is re- assembled the clutch actuator simply pushes the entire clutch assembly out rather that pushing the pressure plate out against the springs ??? Any idea what could have gone wron…

Hi I know that nametab do a 9e clutch conversion but I've heard that you can get different clutch plates that get rid of the cork standard ones. Does anyone know who does these? Thanks.

I am preparing a1955 James in trials trim for this years Beamish Trophy Trial. I want to improve the robustness of the ignition system by doing away with the villiers ignition coil and using an external coil. I have just ordered a FS1E 6 volt AC coil. I need to know in very simple easy steps how to modify the current villiers system sso that I can use the new coil. A wiring diagram would be a great help. I have read the page in the Villiers improvement handbook but it has confused me [not difficult as elctrics are not my strong point.] I really need some expert help but in very simple terms. Can anyone help. I will watch to see what help is given and I can also be contact…

Hi there Apologies for what might seem like an obvious question, but I'm new to Villiers engines ! I want to change the gearbox sprocket on my 8E engine to lower first gear - first glance doesn't look as easy as it is on all the other bikes I have - just thought I would ask advice before I start cheers John

Hi i have my FB being built currently and need some hints on gearing sizes. The engine is 8e 197cc and has the 4 speed box. I might replace with trials cogs but, if i don't what is a good front/rear sprocket combination to get a good usable 1st and 2nd? thanks

Hi folks, Does anyone know if there a source for new crankshafts for Villiers 9e or 32a engines? I'm looking to convert an 11e engine, which has the extra bearing on the right hand side and the longer crankshaft. The plan is to remove the additional bearing (and casing) and to fit the narrower crank. I had seen full circle crankshafts for sale on-line, but they now appear to be out of stock. I'm happy to consider fitting a hammer head crank, but the trend (and the maths) would suggest moving to the full circle version if it were available. Alternatively, is there a modern 2-stroke crank that can be modified to fit the Villiers cases? Before anyone …

Should there be a ball bearing behind the clutch pushrod & when arm is pulled in how far should pushrod protrude from end of shaft see photo. Not ready for re-build but making a shopping list of parts ready for Villiers Services order, thanks.

I'm building a Banvill 197 with a 9e engine that ran fine 20 years ago, currently waiting for bottom end to return from alloy welding. But looking at the top end & comparing it to photo's of the Greeves it was previously fitted in I'm concerned about the length of the carb inlet, it's 3 inch long plus a 3/8" fibre spacer see photo. with the air filter I've bought I don't think it will all fit in the frame loop. I have no problem shortening the inlet but just wondered if anyone had seen one as long as this as previously I had Villier's carbs on other engines.

a simple question for a monday morning.. are the rear engine mountings on the villiers 9e/32a/37a gearbox all the same width?

I see that Villiers services are offering a yamaha clutch conversion for the villiers engine, anyone used it and can give an opinion and also which model it is off?

hi all, has anyone any ideas on replacing the standard villiers clutch on my pre65 scramble bike,[i know not trials] .i would like to replace it with a jap one,ie conbination of the two, that will still fit inside standard castings. any views greatly appreciated.

Hi, I have a 32A engine with a light clutch which doesn't slip or drag but I ride a lot of modern trials and would like the clutch to be smoother rather than on/off. Can anyone help please? There must be better springs, plates, baskets etc. or even, heaven forbid, a more modern clutch. Am I asking too much from my bike as it's pretty good? I only use 6 springs. Merry Xmas everyone, Steve

hi. i have got a villiers engine which i have been running but the cylinder head is scored. is it the spark plug do you think. thanks charlie

Hi all I purchased a whole bunch of new bits for the clutch on my Villiers 37A today. The crank seal on the drive side of the crank looked a bit worn so I got a new Viton one . Is it fairly easy to pry the old seal out of the crankcase end? The old seal looks like it is a standard rubber/nitryl type. Is there any special precautions I should be aware of? Thanks in advance David
