Front Cub hub bearings are 6202 one side, 6203 the other. Rear hub uses 6203 both sides For original unmodified Triumph hubs Why are the shocks on upside down?

Yep, that reinforces my opinion. When it all cools down and contracts, everything's fine. There should be no pressure in the system when your foot is off the pedal because the open port in the master cylinder to the reservoir vents off the pressure.. Take the pedal off, clean the master cylinder where the push rod enters then re fit the pedal and set it up with a little bit of clearance, the pedal may be lower than you've got used to but you can adapt to that. If you bleed the system and get inky fluid out then a seal is degrading, but that's a different problem that will eventually lead to a leak not a brake stuck on.

There's a reason why it's the oil Montesa recommend - it works For some reason Elf don't recommend it for gearboxes with a wet clutch, but it works. Also it doesn't seem to get dirty as quickly as other oils I tried so I just change it very 6 months, not so expensive then. If you can track down some Mitani clutch plates it works even better

Your problem is almost certainly in the pedal / master cylinder set up Either the pedal does not have sufficient free play to allow the piston in the master cylinder to return fully and open the port to the reservoir, or dirt has built up in the master cylinder around the push rod again stopping the piston from returning fully. Bleeding the system may alleviate the fault as working the pedal through its full range might 'encourage' the master cylinder piston to return properly You'd have to be pretty tricky to introduce water into the sealed system via a pressure washer so don't blame yourself there

Fixed by Andy. Starting to re-populate the calendar now. Any NE Club secs who do know what they are doing and when, please keep me informed.

As the guy in the middle, I get it from both sides. From one side, Andy's 'large and complex upgrade that will take several days' has taken a month, and I'm sure has frustrated him more than us. From the other side, I rarely get more than a weeks notice of a trial's location these days, and often this is down to the complex negotiations clubs have to go through to get permission to use land. The locations for the NE Centre trials on Easter Sunday and Easter Monday were only finalised and permits issued on Monday afternoon. I put them on the Calendar as soon as I knew (Tuesday) as it was pointless not doing so. Unfortunately for us, things changed today as the upgrade progressed and they've been deleted, but, as soon as Andy restores my permissions and allows me to post again I'll re-instate them on the calendar. Just so you know. On Sunday, Tynemouth MC will run a trial at Bowershield near Elsdon 11.00am start, contact Gary Salmon 07931 247448 On Monday Bedlington DMC will run a trial at the Mill, Elsdon 11.00am start, contact Colin Battensby 07967 531230 On Sunday 12th April, Weardale & DMC will run a trial at West Bollihope, start time 11.00am, catering van in attendance. On Sunday 19th April, Durham County will run a trial at Dursand Quarry near Stanhope, start time 11.00am, Landowner donating his fee to the ACU Benevolent fund

The paper filters don't like getting wet in my experience. I use one of these: http://www.ebay.co.uk/itm/AIR-FILTER-POLINI-VARIOUS-SIZES-32-37-46mm-STRAIGHT-INLET-WITH-WATERPROOF-COVER-/311082987884?pt=LH_DefaultDomain_3&hash=item486dfdb16c Being foam you oil them like a modern bike with sticky air filter oil, it's amazing how dirty the oil is when you wash it off with petrol. There are other exposed foam filters that work well and are cheaper, but on the Ariel the filter is right under the back corner of the tank and water was running off straight onto the filter. I've had no problems with the covered filter.

Some info here: http://www.trialscentral.com/forums/topic/48407-ariel-gearing/?hl=%2Bariel+%2Bgearing I've retained the gearing and it's fine I've changed the carb to an Amal 622, it's given me a more progressive power delivery at low revs, still plenty of power for hillclimbs etc. Genuine Amal from Surrey Cycles X11 are great if you can get the tubless rear tyre to seat on the tube type rim, on mine the bead drops into the well below 10psi, so I run IRC tube type

428 chain gives you more room everywhere and saves a surprising amount of weight Renthal R1 428 is an excellent quality chain that I seem to remember John Shirt recommending for Gasgas a while ago

No reason at all, though there were attempts to stop it in the past. Several clubs are affiliated to both ACU and AMCA

firesub1 lives in the ACU North East Centre There are 70-80 trials per year in that region, pretty much the only weekend off is the one before Christmas, but, we ride on Boxing day to make up for it. Every event appears on the Trials Central Calendar a couple of weeks before and the results are always on the home page by the middle of the week.

With the Bedlington MC Trial having now closed for entries this weekend, Shaun Hayden is opening Dursand Quarry for Trials practice this Sunday 22nd June. Dursand Quarry is halfway up Crawleyside Bank, north of Stanhope in Weardale. Anyone interested should contact Shaun on 07908 173 549

I posted the event on the calendar when I was given the year's dates by NEC ACU Unfortunately I've had no contact from any Newcastle MC member confirming that the trial is on. However if it is on it will probably be at Ridsdale on the A68, not Redesdale. (Redesdale is further north)

Candle wax? Does it not just burn? To anneal Aluminium, if you rub soap on it then heat it until the soap turns brown you are at approximately the correct temperature. Hold the temperature until even then cool slowly. Note: If you get it too hot, the soap will go black as the Aluminium melts. This is handy for annealing soft aluminium gaskets etc, not so sure about a brake pedal. In my experience, on the 4RT, if they are not exactly the right shape, they just dont work properly. You can obtain a pattern one quite cheaply, they work well but do crack if bent.

Clubs in the North East ACU Centre organising trials in 2014 are: Bedlington & DMC Castleside Trials Club Consett & DMC Durham County Trials Club Newcastle Motor Club Seaton Delaval & DMC South Shields & DMC Stanley Trials Club Tweed Valley MCC Tynemouth & DMC Weardale & DMC There are more than 70 trials per year in the centre, all are promoted on this site, look in the calendar to see what's on where and when, look on the front page for results I'm Trials Sec for South Shields & DMC but it makes little difference which club you join, we charge £5pa the rest are similar. Once you have joined a club and then joined the ACU you can ride any trial in the centre and any open trial out of the centre. No need to jump in and join a club until you are ready to compete. Once you have bought a bike I believe you can pay to practice at the Warden Law facility near Houghton le Spring. When you are ready to compete, the Wednesday night series run by Consett & DMC are a good introduction to the sport, nothing too difficult or serious, start at 6pm and you're in the chippy for 8-30 having had a good play on your bike with like minded people.

Well, I have the standard cam in a 250 motor and it's very strong at the bottom end. But if I try a mate's similar bike with the R cam, whilst it has a good bit less at the bottom end I really like the extended rev range. It depends on the sort of trials you ride. Plenty of R cams available and not a difficult swap, drain all the oil, loosen off the valve clearances and take the covers off then lay the bike flat on its side and you can pull one cam out and shove the new one in before the cam followers drop down.

Few things amuse me as much as a monster flash going off in my face when I'm riding a section, normally it lets me know I'm getting to the tricky bit and I'm going to see it all in greenish monochrome

MK 1.5 is available in different choke sizes, has a proper enrichment device instead of a tickler and has the pilot jet at the front centre of the body instead of at the back and on one side. Mine seems a lot more waterproof than the MK 1 when washing the bike, maybe it's removing the tickler that improves it

Still working on my 'new' 500 long stroke Ariel The carb is an Amal concentric 626 and it's worn. Specifically the slide is very worn with loads of movement in the bore but a new slide is very tight which suggests a poor / distorted body. The jetting is bushed pilot, 106 needle jet, 160 main jet, 3.5 slide. Now I could order a new carb with the same jetting but I think people are using 622 carbs these days to improve low speed running and control. If that is the case would I keep the same jetting and slide in the smaller carb or would I have to change it?

I'm told it's fitted with a Norton clutch at the moment Does the Jawa clutch really have the same splines as Burman?

Thanks Mick, I like them slow so I'll check the first gear ratio, then perhaps drop a tooth on the Gearbox output sprocket, I can experiment that way without changing the chain.

Have just purchased a 500cc Ariel and I'm wondering what gearing people are using. Currently its Primary drive 14/42, Final drive 16/48, gearbox described as standard GB47 It feels high geared to me (across the garden), just don't know how much to lower it
