  1. This may be the problem. There needs to be around 2mm free play between the lever and master cylinder piston. As everything heats up, the fluid expands and because the master cylinder is adjusted right up, the fluid can't flow back into the ressie. So the clutch becomes disengaged all the time. The master cylinders piston needs to be able to return fully back. Check the adjustable pin on the clutch lever that pushes again the master cylinder piston. Back it off until there is 2mm of movement before the pin actuates the piston. Check all the other master cylinders also have this 2mm free play.
  2. Clicky linky above! (I though it would quote the compete thread)
  3. I suffer from this and it always happens when I change bikes. Until I get the bar height right, my left hand and wrist almost cripple me. It's often due to the bars being just too low and that throws my weight too much forward and down my arms/wrists. Throw in the all the clutch action and my left hand and wrist soon start to complain. It usually doesn't take much of a rise of the bars to sort it out, 4 or 5mm rise usually works for me. There are some easy things you can do to strengthen your wrists. Those grip things won't work much on the wrists, though they do work the fingers. You need one of those rubber bands (that physio's use), available in sports and fitness shops, start with a low resistance band first. Hold your hand/wrist flat on a desk/table, wrap the band around your fingers and hold the ends of the band in your other hand. Work your hand/fingers side to side (not up and down), keeping your arm still while you pull against the resistance of the band. You can swap it around, turn the band and work the wrist the other way, though it's best to tie up the ends on something this way. Do around three sets of ten a day, or until it just starts to ache a little (not a lot) you'll feel it pull and work the part of the wrist that causes your issue. It'll work and strengthen those tendons and muscles right in the lower forearm/wrist, my physio taught me this and he rides downhill mountain bikes, works a treat!
  4. It's common for a blocked pilot jet if they'll start and run on choke, but stall without choke. Though small air leaks can cause the same sort of symptoms but you usually have difficulty starting and a bouncing or screaming idle when they do start. Unscrew the pilot (smallest jet), hold it up to the light and peer through it, you should see if it's blocked. Modern fuel goes stale very quickly and can leave a green gunk in the float bowl which tends to gum everything up, particularly the pilot jet and the float bowls inlet valve and seat. (when the inlet valve gums up they can stick open and pour fuel out of the carb everywhere if you're lucky, if you're not, raw fuel will pour right through the carb and into the crankcase) Best to always drain the float bowl if leaving the bike for more than a week. (drain means undo the bottom of the float bowl, not turn off the fuel and run until it runs dry!)
  5. Check the carb again, sounds like the pilot jet is blocked.
  6. It's already been mentioned, but car derived vans are excellent trials bike transport that double up as family hacks. The vans they are based on usually attract high insurance premiums, even though you're using them for SDP. It's probably due to the break in risk. Some of these small vans can also carry a higher VED than the car versions. Check the logbook to see if it's classed as a car. (M1 methinks) With a van derived car, you're more likely to find petrol versions if you don't want to get clobbered with whatever the Govenment has up their sleeve for diesel owners in the near future. You can find the odd petrol Doblo (1.4 not the 1.2, it's dog slow), Berlingo and Partner MPV's dotted about for reasonable money and they've usually had an easier life than an ex Royal Mail or BT van version.
  7. When they were originally released, Vertigo advise was 40ml to 5 litres of petrol. It seems that got altered to 25ml to 5 litres of petrol not long after. That means some early owners got printouts advising 40ml and later owners got them stating 25ml. I have a club mate with a bike a little older than mine came with the 40ml recommendation, mine 25ml. I've ran mine since new in July 2016 with the 25ml mix and it's fine. Though I've not used the free bottle of Strawberry scented oil that came with it, don't want to spend all day with my belly rumbling! I've only ever used one brand of 2 stroke and always bought their synthetic offering, It's never given me any issues and I don't plan on that changing. BTW, some of the newer owners may discover that the plug soots up (even on 25ml) after a few hours. The BPMR6A is a little too cool for them, a BPMR4A has a little more of the tip protruding, runs a little hot and so far seems to work better.
  8. Does pulling the clutch in make a difference to the noise? It's not uncommon for clutches to chatter or rattle.
  9. There's no easy answer to your questions as what might work on one bike doesn't mean it'll work on another. Carb tuning can be a little tricky and it's tempting to keep at it, chasing something better when perhaps you're already there! Warm the engine up and turn the idle speed up ever so slightly. Start with your mixture screw at 1 and 1/2 turns out as your base setting and adjust in 1/4 turns. As you alter it too rich the engine will sound dull and fluffy, too lean and the revs will "hunt" ie, the idle will rise and fall unevenly. Once you have it idling smoothly (as possible), reset the idle back to normal. The needle setting effects the way the fueling acts as the throttle opens and the fueling changes from pilot circuit to main jet. Start on the middle groove. You'll need to ride the bike around and see how it acts on slow and sudden throttle openings. Lifting the needle up (low clip) with cause a little more fuel to pass = richer, lower the needle (high clip) less = leaner. (It's been a while, but I seem to remember mine had the needle lifted quite high to over come a stutter on sudden throttle opens). Float height can also cause rich and lean running, too low and it can lean out, too high and it can flood up as can the angle the carb is fitted, particularly up and down hills. But like I wrote, it all depends on the bike and what parts are fitted, air filters and exhausts can effect setting as can altitude . Then there's Cubs that are fitted with R cams, they just don't tend to idle too well to start with!
  10. I've never found my 300 Combat Camo to be anything other than torquey. It's never felt too OTT or some sort of missile that scares or is difficult to control, but mine is a 2016. It just seems to me the engine is "weighted" perfectly with a feeling the power delivery is solid rather than peaky. I came from a 2014 Evo 300 and that certainly did need a flywheel weight to calm the mid throttle "hit" it seemed to suffer from. Although two different weight flywheel weights are available from Vertigo, I just never felt the need for one. There's a good chance the 300 Camo wasn't quite stock if it was a customers bike you tried. I know of one customer who turned up at a test day with their own bike late last year and they had already altered the sprockets and fitted a slow action throttle, though for the life of me I don't know why!
  11. Without doubt the Fantic 200. The forward kick "Pro's" are getting hard to come by, but the rear kick Minarelli engined "Trial" ones are still quite plentyful. Sweet engine and a decent handling frame that worked well straight from the off. You also won't loose a penny on one, they only seem to go up in price!
  12. I bought one of these years ago, it was just a few boxes of parts. Same thing happened, someone took it apart due to water and oil mixing in the gearbox. All I could find was a rough, photocopied exploded parts diagram from John Lampkins to help me, it was enough, but it was hard to read! Turned out there's a couple of small seals (and bearings) on the waterpump shaft that are prone to leaking. I seem to remember the shaft runs right through the gearbox, it's driven from the left side, but the pump is on the right with the seals/bearings between the cases. I also seem to think the head seals with two rubber O rings, worth checking these are ok along with the grooves they sit in if there's a chance it's over heated. Not a bad bike for it's time, but the alloy frame isn't great, they were prone to the swinging arm cracking, just around the voids where the bearings/bushes fit.
  13. Just to add to b40rt's post, you can also get British Army Goretex Boot Liners from the same sort of sellers for very little outlay. Just pop 'em on over your normal socks before putting your boots, you'll never have wet again.`
  14. If you live in the EU, it worth ploughing through the consultation document. The ramifcations don't just effect the users of the types of vehicles outlined, (and yes, bumper cars are in scope) but in fact impacts on all motor insurance policies and their costs. Buy any motor insurance and you pay into a pot that the Motor Insurers Bureau uses to settle certain claims (untracable or uninsured types). I'm certain other EU countries have similar schemes as they all follow the same EU directives. This pot will need to be considerable enlarged to encompass all the same types of claims from the "newly to scope" vehicle list. It'll increase every motor premium for every type of vehicle. Also, don't pin your hopes on Brexit, the UK still has to comply until it's out of the EU and then some. The hope is they put a review date (sunset) on legislation so it can be backtracked in future, but you can't see it being on the top of anyones list to unwrap once the UK has left!
