Well just put mine back together last week, and it didnt have any before and i didnt fit any this time. Suppose i'll soon find out if it needs them - just not for a few weeks cos the frames at the powdercoaters at the mo.

+1 hehe, yup i was there last month. used a three-legged puller with the legs chained up. In the end went for the get it as tight as you can, then using the longest bar you can, carefully approach and give it 1/4 turn, sweating - usually with eyes shut. retire to safe distance, wait 5 mins and repeat. On the 4th or 5th 'turn' the aforementioned BANG, jebus where the "

They are definitely still going, ordered some bits from them for my Montesa over the phone friday lunchtime and was stunned when I got the parcel containing them Saturday morning in the post at 9am!! Thats really really good service as far as i'm concerned. Very helpful on the phone too, got to be worth giving them a ring to chase the order up......

Thanks Woody i'll def. be careful with the gearshafts then.... As Dave says dont need to split cases for crankseals, but likely to as I want to check gearbox as had some trouble finding neutral when engine was hot n running. Plus I can properly look at the insides to see whats happened in its long life (Its only 1 yr younger than I am so bound to be a bit knackered somewhere in there!) may do crank bearings as well if they look tired, Sandifords have them in stock and theyre not particularly expensive

Ok when I stated above that this wasnt going to become a full on restoration I may have been a bit hasty Rode it about at the weekend and was pleasantly surprised - everything seems ok and works quite well but the engines bogging on part throttle (better when warm but still not good) so either the carbs v.worn (which it is) or the crank seals need doing (which for a '72 bike isnt surprising) so the engines out and is gonna get properly gone through. then I started stripping the rest, you know how it is, quiet sunday with nothing else to do and a garage full of tools, Now I know where I can get powdercoating done at cost so can anyone help me with the correct colour for the frame please?? I know being a '72 it should be grey but does anyone know the paintcode (or RAL colour) I need, and would it be matt, gloss or satin (I'd guess gloss) As for the carb, it seems the OKO flatslides appear to be the best cost/performance/ease of fitting compromise, so does anyone have experience of fitting them to an old twinshock like this ? (Found the OKO.co.uk site and will be contacting them down the line for advice) For some reason OKO wont work on the search function on here, though ive found a couple of mentions of them by searching for 'carb' Thanks T.

Two Lane Blacktop needs consideration too, another wonderful film from the same era

Thanks Woody, I wont disturb them then and leave them as is (It certainly makes access to the plug easier this way round - which will be why someone has swapped them previously it seems). Popped a new plug in earlier and it fired and ran first kick so getting somewhere with it now Only had what fuel was in the pipe as got tank off at the mo, so couldnt tell much more than that but i've got most of the weekend free to work on it so hopefully can get a blast around on it soon to check everything else is in a serviceable condition

Hi another question regarding my 247, It has a Decomp fitted, but it is in the vertical position with the plug at the 45' angle position - is this correct or should they be reversed? I'm not aware of the actual combustion chamber shape, but suspect that the central position would be a better place for the plug for a uniform burn Should I swap them over? (I'm assuming that they are both 14mm)

Thanks Jay, I've got points and a condenser coming in the post, they're the first thing I brought as they were only

Thanks David, investigated inside the cover and the stop is still on the shaft, but the internal webbing it hits against is broken up so that explains that. Solved the kickstart issue, as now I know the kickstart isnt original it was 'adjusted' with my vice and a large stillson

Having some issues getting my cota 247 to run, got a spark but no joy yet. Will be putting a new sparkplug in as soon as I can get to a shop (B8HS i believe, though its currently fitted with a BR6HS resistor plug), but in the meantime checking other issues, timing looks about right so thought i'd check the coil Its got a red HT lead motoplat and with a bit of searching found this site, (http://www.yankeetwin.com/motoplat.html) that states the resistance across it should measure between 7000-9000 ohms. Mine measures 12,150 every time. does this indicate that its snafu and i'll need to locate another?

Another technical question, Why would the kickstart be clipping the end of the gearlever (and knocking it into gear ) at the end of its travel?? I've moved the kickstart forwards a few splines from the pic above, but it is still clipping the end of it, its really putting a cramp on trying to get it started!! Should there be a stop to the kickstarts travel? it will go right round to beyond the lower vertical and a begin to come up again forwards a small amount Is it as simple as 'Thats not the right kickstart lever?'

I'm aware this is digging up old-ish topics but thought this may help a little for someone..... looks to be plenty of room for another in here , plus they all come with a towbar so 2 more on a trailer too Its a '93 diesel Mk1 caddy as mentioned above. gets 50 to the gallon and if you can find them before the V-Dub kids crowd does theyre a remarkable cheap way to move bikes about

Hi, Terry (Tael) here, been lurking for a while reading up various stuff in an attempt to know what to look for when buying an old twinshock to get back into trials after a 20+ year layoff (Did some in early teens on an old Cotton with a starmaker in that my father had) Just managed to get a cheap little thing finally ( a Cota which was my first choice of bike even before reading up) which I've detailed in the twinshock forum. Love the look of this place, I'm a member on quite a few forums regarding my other bikes but the quantity of useful information and helpful users on here is very impressive. Hope to be able to fit in here and pick a few brains along the way Terry Norfolk U.K.

Hello All, just completed a 180mile round trip to pick up this Its as far as I can tell a MkIII cota 247 in tatty but mostly complete condition (only the airbox not present) The plan is to get it in a running and into a basically useable condition to do a few white route wobblers trials with my local club, as I want to get back into trials after a 20yr+ layoff (i.e. since I was a teenager) ive got three years of practice time before i'm eligible for the over-40 class . I had better point out now that this is NOT going to be a full restoration job (yet) as ive got enough roadbike projects to keep me busy at the moment, but who knows for the future The frame no is 21m674* and the engine 21m672* so although they don't match they're within 20-odd of each other. First question for anyone with more experience of these than me (i.e. most of you), it would appear to have an earlier (MKII) LH engine cover fitted. Am I right with this assumption, and what issues may this cause? Oh and would I be correct in dating it to 1972? Terry, in unseasonally sunny Norfolk U.K. (oh and it was v.cheap too, so not bothered that I appear to have brought another likely moneypit ) EDIT: having found another site with more model info it appears its a very early MkIV not III, hence the later style bodywork and top-end, MkIV started at number 6600 in '72 according to here- http://www.geocities.com/cotamontesa/
