  1. I think he meant that he only used 1/2 the charge on the batteries. "They were still pulling well"
  2. Some more pics I took these while competing in the Pipers Pool Trial, Launceston last weekend. All on a sigma dp1, manual focus, 28mm equiv, F4, iso800, auto shutter from 1/40 - 1/125. Camera was handheld, panning on the slower shutters.
  3. One of my favourites Although I have a DSLR I usually only carry my Sigma DP1 with me, which gives SLR quality in a pocketable camera. A fixed 28mm equivalent lens means you have to get close to the action but can give some interesting images; for this shot I was lying on the ground. I use manual focus so there is zero shutter delay.
  4. We have ignition! A few nervous moments as it took a few kicks to get going the 1st time but it is now back to its normal 1 kick starting. It seems to run slightly crisper now thanks to dropping the needle a notch. Just got to get some pop-rivets the right size so I can mount the front mudguard that also got broken last time out and I'm good to go.
  5. Thanks for all your replies. Since the gear box was short of oil I called Bob Wright to ask about crank seals. Before I even mentioned the shortage of oil in the gearbox he said the symptoms pointed to the clutch side crank seal. Apparently the clutch side seal also fails more often than the flywheel side. I bought a pair of seals but will be keeping one as a spare. I won't do the flywheel side unless it fails. It was a bit of a mare to get it all apart, but the interesting thing was the complete lack of marks from tools on the metal. I would say that I am the first person to have the cover off since it left the factory which probably explains why the weight on the end of the fly wheel was a pig to get off the crank. This, along with the general condition of the bike and the practically mint carb all points to a bike that has had very little use. I need to get some more oil for the gearbox tomorrow. I'm also going to take the front pipe off and flush it through to clean out any deposits. Then it'll be fingers crossed time.
  6. I had a closer inspection tonight. float bowl is fine, carb clean and in very good condition for a 28 year old bike; hardly a mark on it. The needle was in it's highest position so I dropped it down a clip but this isn't my problem as it is not even attempting to start now. I don't know how you recognise whether the flywheel has slipped, I wouldn't have thought this likely as don't they usually have a woodruff key to hold them in line? Not a massive spark, but it was there and blue so it is probably OK on the ignition side. Anyway I drained the oil and only got 850 ml out so it looks like a set of crank seals may be required. I read in another post that you can get them out with the engine in the frame by filing a couple of spokes down into hooks. Do I need any special tools, eg pullers for the clutch and flywheel? I'm thinking that I might lift the head off and inspect the bore while I am working on the bike. Anything else worth checking while I'm at it? Please excuse my ignorance; I'm more familiar with 4 strokes and, apart from replacing the power-valves on a kdx, I haven't really worked on 2 stroke engines. Cheers
  7. To rule things out before I tear into the motor?? crank oil seal : drain the oil and measure what comes out. If it is 1 litre can I rule this out? Flywheel : remove the left cover and have a look I suppose. I don't have an engine manual but do have the owners manual on disc from ebay. I think it has the procedure for checking the ignition pick up position. Can the flywheel actually shift on the crank? I doubt it is a bent needle as it was working fine and and I have not had the carb apart to bend it in any way. Is it possible that the problem was caused by repacking or am I barking up the wrong tree? Could a previous owner have adjusted the carb to compensate for an empty silencer; pack the silencer and it is then way too rich? What are the standard jet sizes? I think I read the needle should be 2 from the top, is that right? Thanks again
  8. Greyish smoke putoline full synthetic at 50:1 problem started after a long uphill, at or close to full throttle. Once it happened the bike stopped running right. Next lap same again, top of the hill and it was belching out like it had a 60 a day chain smoking habit. each time it got progressively worse and harder to restart. It got to the point that I had to leave it for a while before kicking several times to get it going, until it gave up altogether. Airfilter was cleaned and oiled when I got the bike. I have checked it and it is fine. Certainly no difference from the previous trial.
  9. Ok, here's the problem. I have a nice tidy fantic 200 which I bought from the twinshock shop a few weeks ago. I have been going through sorting a few things out, tightening spokes, air filter, gear lever and silencer to front pipe seal. Nothing serious, just a few bits and bobs and the bike was running really nicely. With the bike being a few years old, and the silencer showing no signs of ever having been opened to repack, I thought it would be a sensible move. I cut out a section from the inside of the can, cleaned it all out and repacked with silent sport loose packing. Not too tight but enough so I could lay the cut section of can on top of the glass and it was supporting its weight prior to welding the section back in. Bike starts and runs fine, nice and quiet. A few minutes in the street shows no problems. Cut to the following week and a muddy trial. Bike starts fine and runs OK for the first few sections, but after a long hill climb between sections it starts smoking from the exhaust like crazy; then it coughs and dies. A couple of kicks and it starts up and completes the lap but with further problems with the engine stopping getting progressively worse. I tried a change of plug but after a few minutes it was back as before. All that seemed to help was running the bike with the fuel tap closed, opening it to let a little fuel through and shutting it again. Even this didn't help for long. I have checked the plug etc and it is getting a spark. I am thinking about the silencer as it it the only thing that I changed between this wekend and the previous trial when the bike ran faultessly. Looking up the silencer outlets, the top one certainly has thick oily deposits which appear to be clogging the perforations in the tube, the lower outlet also but to a lesser degree. Perhaps I have caused a problem by over-packing the can, or should it even be repacked as there was no packing left in there when I opened it? Is there anything else I should be checking? Cheers
  10. I read this the other day. It has some interesting info about available upgrades that can be made to the bikes on Page 5. 2 days later my lad decided to ride off the edge of a large hump, coming down the steap side rather than the gentle slope he had ridden up. Despite me shouting BRAKES he went into a stone wall and managed to shorten the wheelbase by about an inch - oops! Fortunately no damage to son or bike apart from the forks. I called up osetbikes.co.uk and we discussed the options. 2 days later I got home from work to find a parcel in the garage (the joys of living out in the sticks) containing a set of the RST upgrade forks and a 600lb spring to replace the stock 950lb spring in the rear shock. Care (a hammer and screwdriver) was needed to remove the bottom bearing seat from the old forks to transfer across but otherwise the procedure was pretty straightforward. First ride out today and I would say it is a big improvement at both ends - both wheels looked to ride over bumps better with the suspension absorbing the impact (previously the whole bike seemed to bounce off) and traction on rough surfaces looks to have improved. The other advantage is a much tighter steering lock. I don't know whether I could justify
  11. I don't know how they would be on the GG but osetbikes.co.uk are now importing the kenda-oset trials tyres which come in 16" sizes for front and rear. I have a rear ordered for my son which should be here soon.
