fourex

All good, All sorted. Thanks.

Can anyone tell me if these are the same, I thought the way the brake plates were held in place was different for a start and I would have thought some dimensions between the two would differ also. Thanks.

Reimar Buerkmayer in Germany has the opaque/translucent guards you seek, I bought a set from him about 14 months ago, he still has them listed on his website, refer attached and scroll to end of Ossa parts. http://buerkmayer.de/Ossa.htm

Grib in Spain again, https://www.grib.net/race/prestashop/gb/sump-plates/40-72-bultaco-sherpa-199-plus-7075-sump-plate.html

I think it's too late for that now, you've powder coated the frame, can't alter the original Bully footpeg brackets now without wrecking the coating. I don't think you're slow enough in your thought process 'slowrider', you should procrastinate more like I like to do.

Grib racing from Spain is one alternative, not cheap but a very nice bit of kit. https://www.grib.net/race/prestashop/gb/brakes/96-104-brake-pedal-bultaco-left-aluminium-cnc.html Also JCC also in Spain. https://tienda.jcccompeticio.com/en/home/257-palanca-freno-sherpa-199-izquierda.html

The open side of the seal containing the little internal spring should be facing where the oil is coming from.

Yes, I see what greychapel was referring to, apologies.

Left leg is wrong, right leg looks correct. Pull dust cover off and measure from top of alloy fork tube down to mudguard mounts, should be 60 mm. Common problem with left fork tube is that a previous owner has ridden the bike without the front brake stay being fully tensioned/tight resulting in it breaking away. They're as rare as hens teeth, MH part # M0CM1-35017H, Cota 349/4 part # IZQ.5139.017, Cota 350 part # IZQ.5139.01702. If you find any, please let me know, but nobody else . MH 349 had a red frame, Cota 349/4 and 350 had silverish/greyish frames.

Bar risers are not an option, look at the pics he's put up of the Beta hinged clamp which is integral of the top triple clamp.

Yes, I see your problem, those S3 adjustable clamps I suggested are of no use. If your bars are Reikon "9003" then they have a height of 110mm, Renthal 673 are 100mm, Renthal 829 are 115mm but there's so much more to how they get to that end height, finding the right handlebar for oneself can be a costly exercise. Jitsie have a few options in their fatbar range if that's of any help...........

GasGas has hinged clamps also, probably something about saving a few grams or better clamping ability.

Renthal do a 829 bar which is roughly 15mm taller than the 673, but they can be hard to source. https://www.renthal.com/moto/trials-110-1 S3 do a nice adjustable bar clamp that works well with the 673, gives a 13mm lift. https://shop-s3.com/gb/home/51-adjustable-handlebar-clamps-s3.html

I'm a fan of those S3 bar clamps due to the 13 mm rise and fore and aft adjustability, they worked a treat for me on my GG, enabling me to keep the std Renthal fat bar which I like. Did not like their "Buffalo Bars" however, I tried these before discovering their bar clamps.

Hello Listerjag, You ask a lot, and I know that is what Maxton requires but I doubt you'll get all those dimensions and weights until you do it yourself on your own bike when it arrives. Even if someone did post up the info your after, would you really want to rely on that for being accurate when you are going to pay approx $1000 NZ for Maxtons delivered to your door, I wouldn't. Wait until the bike arrives.

Cyclesavant in the US has the right side nut. https://www.ebay.com.sg/itm/Montesa-Cota-Enduro-Cappra-OEM-lock-Nut-p-n-0092-10020-NOS-49-123-250-360-Impala-/293953595390 A google search of left side nut 2160.03703 showed one sold or finished on ebay just before christmas, keep searching Left side spring washer part # is 0093.514, right side washer is 0093.110. good luck.

Yes definitely Mahle, I just checked an old motor of mine.

There's not a lot out there that I'm aware of, Robert Cochrane in New Zealand has some bits, his site as follows........... https://kawasakikt.tripod.com/FREDKT.html Google searches of "KT parts" will often take you to someone on ebay that has bits for sale, if you know the Kawasaki part # of what it is you want, type that into google and see what comes up. A couple of places that 'might' have some NOS are......... https://vintagekawasaki.com/webshop/index.php?main_page=index&cPath=46_426 https://www.ebay.com/str/MachIVMotors/NOS-Kawasaki/_i.html?_pgn=73&rt=nc&_storecat=4738823015 Our Australian KT's did not have turn indicators, blinkers as we like to call them, here's a picture of the blanked off switch block on my '76 KT.

These parts diagrams might be helpful when trawling the net as it gives the part numbers, dimensions and number required. Note also that only bolt # 33 appears to be specific to the 348/349 as it starts with 51. Bolt # 32 would appear to be a carry over from the 247 as it starts with 21, bolt # 31 starting with 73 is from the Cappra I think etc,etc. Here's bolt # 34 on cyclesavant's ebay site, $7.50 is a bit steep, but he is open to offers. https://www.ebay.com/itm/Montesa-Cota-335-Engine-Case-Cover-Screw-p-n-6660-11201-61M-1987/303822271821?hash=item46bd37f54d:g:E-sAAOSwWzRf41ij

If you left click on the brochure pic it should enlarge enough so you can see the bracket on the left side of the swing arm on that shot of the plastic bash plate. Otherwise here's a pic of the mk 2 side stand bracket, it looks the same as the mk 1 brochure. PS: Search the Ossa forum here regarding rear brake cable arrangement, it's another of those odd things that Ossa did, like 12mm axles. I'm sure I read someone asking a similar question in the last year or two and the responses and photos made it clear. Venhill make and sell the rear brake cable.

Not an expert on Ossa by any means but I do have a mk 2 and have gathered some info and pics over the years, your bike looks like a good starting point for a resto. Your bike certainly looks like a MK1 due to flanged Amal carb and the solid fork bottoms. Have a look at the attached brochure shot that shows a side stand for MK1. I think your round rear frame hoop over the guard might be bent down, but could be just the pic angle or those universal alloy guards. Attached is some pics of my rear frame hoop, you got to remember that the seat is attached by two bolts that go through the rear guard and the flat frame hoop. Hope this is helpful.

Left Trials maybe early '76 to dabble in MX. Maybe back to Trials '81 or '82 through to '95 or '96. then back again 2014. Something like that as I recall.

Good times indeed David, those Montesa pics are from Biddaddaba late March or early April 1974, you might be amongst that group at riders briefing? The bloke sitting backwards on the Sherpa is Rod Maclean, I think that was a Logan River Trial possibly at Mt Cotton ? Can't remember what shocks I had on the TY, but I do remember the laid down mod was done at the Motorcycle/Mower shop on Logan Rd Mt Gravatt by their mechanic who I believe was Steve Hope but I didn't know that at the time. He did a good job by also welding in gussets to prevent the rear downtubes from bending, thanks Steve.

I never experienced that problem with it jumping out of 2nd gear, probably because I couldn't wind it up to the point of needing 2nd plus I was only 12. Can't help myself here,I'm sorry, found some pics of a young fourex riding his new 123 around the back yard the day it arrived plus some pics from my 1st Trial on the same bike. I think I looked p****d off because I didn't like having photos taken as a kid, I don't think I'd realised at that time what a dud of a bike I had. But it's some pics of a brand new Cota 123. See smiley face once on a TY 175.

The 1st Cota 123 was the biggest heap of ***** ever made, I've been scarred for life after my Dad bought me one at 12 yrs of age (brand new early '70s), even at this young age I knew there was something wrong with this bike, it was so gutless. Thank god he bought me a TY 175 when they were released, but I've still got the Mental Scars of that Cota 123. Beautiful looking bike for a collection not something to ride. PS: Not to mention that 20/17" wheel combo, welded clutch and front brake lever mounts to the bars,no chain tensioner and not enough power to pull the skin off a rice pudding. Awful, awful.
