  1. Hi, I can't be sure which model, it's oldish though. The thread that I am identifying is 25mm x 1.25 pitch. I am hoping to fit these forks, or at least the yokes to my new Bantam frame. Wasn't desperately impressed by what I got from Progressive so have decided to make my own. Have made the headstock to suit the yoke, rather than the other way round. Dave
  2. Hi folks, does anyone know what thread is used on the top of the yoke stem, the one that holds the top yoke to the steering stem? Further to that, does anyone have such a nut, and better yet lend or sell me a die to cut this thread? Thanks in advance for any help. Dave
  3. Hi, have found the shaft and arm, but can't find the stop, cable or h/bar lever. Let me know whether you are interested and make an offer. The stop, if I remember correctly was integrated into my engine steady bracket. Dave
  4. Hi Jonv8, I may be able to help with some or all the parts you require, I removed the valve lifter from my B40 when I lowered the comp ratio to 6.5 to 1(with a really spiteful cam), I will have a look tomorrow and see what I have left.
  5. Hi, I am seeing lots of names of frame builders in this thread, I was looking for a Bantam rigid frame, but Drayton, I am told are not in production at the moment, so where else can I try? Many thanks for any info. Incidentally, I tried twinshockshop with no luck. Dave
  6. Hi, at the risk of being wrong, when I spoke to him at Horsmonden in Kent it was a 65cc based on a TLM50, very much modified and very nice albeit a bit revvy. Horsmonden is the late Mick Holloway's ground, much used by his sister Joan Westbrook, for those who haven't had the pleasure of meeting them. Joan is famous for her appearances at the Scottish, and is not currently as well as she should be.
  7. Hi, I am resurrecting a rigid Bantam, now 185cc with a modified frame at the rear end and loop under the engine. Two problems have come to light, where the rear of the frame was widened for the tyre it seems to be lop-sided, i.e. tyre clears on chain side, but is very close on the other. Main prob though, is the steering head angle, having fitted honda forks with parallel steering stem, it looks like a chopper! Can anyone tell me what the steering head angle should be, as other people I have heard from say that other forks have been fitted yet the bike looks normal. I am judging this against tlr 200 honda and my 4rt, the 4rt isn't really comparable of course, just using it for rake and trail angles. Dave
  8. Hi, have had one on my tlr for several years, excellent fitment, if only to get rid of chunky original and original levers at the same time. I made my own throttle cable, but if I remember correctly the original cable can be used if the outer sheath is shortened a bit, if you do it this way cut the outer Carefully!!
  9. Hi, just seen this posting, I used to see Renee Bennett and her husband Howard Powell in the late 1960s, around Plaistow (east London), where they had there motorcycle shop. I'm not sure whether it is still going, but Howard moved the shop to East Ham. Renee was a fair rider,and was usually seen on a Greeves at that time, Howard rode either a Greeves Anglian, or a Bultaco. She was the daughter of a famous local car spares dealer, and gym owner, Wag Bennett. She was very much into keeping fit, and was very shapely.
  10. I wasn't comparing the two directly, the two strokes of the day were spiteful peaky engines, but having ridden several Kwaka triples and more 4pot 4strokes, I know which are more controllable, so imagine both being tweaked for racing. I had a lovely Ducati a few years ago, and tried 'knee-down' and felt a complete ****, on the road. I did manage to get my knee down a couple of times, but really couldn't see the benefit, so carried on in a 'tucked-in' stylee. Some of the two strokes, if I remember correctly had a device a bit like a rev limiter, to cut cylinders and slow the bike a bit more than just being on the over-run. The comparison of the tyres relates to evil power delivery of the old two strokes and the managed engines of today, they may be more powerful now, but their delivery is much nicer, no going on the pipe and doubling the torque in seconds. The greatest respect is due to the riders of todays GP bikes, but I will retain my opinion about untidy riders. As a side issue, when will something be done about the ridiculous speeds that are being expected of riders on the Island? The 100 mph lap was a hell of an achievement when it was done, and on the bikes it was done on, but it seems to me that it is just dangerous to be marching on at 200 mph plus on roads not much improved since the Seventies or so. Rant over, I'd take my Valium and lie down for an hour. Dave
  11. Hi Richt, that may be one theory, but fourstrokes have much more engine braking than two strokes, which is , I believe, where this ridiculous style originated. Years ago, when twostrokes were the thing, engine braking was limited, and brakes not too good either, a lot of riders would sit up, putting their body in the slipstream to slow themselves down a bit, not these dozy antics. While I'm on the subject of riding styles, is there any reason why a rider has to use the run-off area, as though the track is not wide enough. The run-off area is just that, for a chance to recover from too fast an entry into a bend, not a track extension. When I raced karts we were warned for use of it as being unsportsmanlike. If you don't like the confines of a track, try desert racing.
  12. Hi, my tlr 200 Honda is fitted with them as standard, they are for pre-loading the fork for lardarse riders or very rough ground.the norm is no air pressure in them but they can be pumped up to about 3psi or so to adjust sag with a heavy rider aboard. Pump them up with a push bike pump, gently, till you get the sag you want, or to stop bottoming out. Dave
  13. Hi, having watched a lot of road/track racing through the years, I am becoming more incredulous at the recent riding styles of late. Back in the fifties and sixties TOP riders such as M Hailwood etc used to ride very tidily and tucked in. The tyres of the day were by no means as good as those in use today, even for the lower power outputs available then, bearing in mind that the rider used the THROTTLE to control the rear wheel, not traction control and ABS systems. Why is it that 'knee-down' became the fashion, I thought at the time it became popular that it was 'posing', especially when ordinary road riders started doing it, claiming it was essential. to keep this missive short, I will cut to the point now, why oh why do a particular few riders hang their WHOLE leg out? This puts me in mind of moped riders who drag a foot for a hundred yards when pulling away from the lights. If you do not know how far you are leaning going into a bend, it's time to stop riding, if your leg is stuck out when the bike lowsides you deserve to break it. For Christ's sake, learn to ride neatly.Hailwood is said to have achieved lean angles of 45 degrees, on tyres of less than modern standards of grip without all the antics performed these days.
  14. Hi Bashplate, that is what I was thinking of doing, I thought that the collar or whatever it is , might have been pressed in in which case it should press out. If it does press out it can be replaced with a brass or bronze bush. I will have a go at drilling it out when I get round to lowering the footrests, the last job to achieve perfection. Dave
