Hi Guy's Hi Jonah, Glad you are still into trials bikes, has you and Frank spurned a vast crop of youngsters in the sixties that thought they had no chance to own a decent trials bike before Sprite appeared. And thought you could not compeat without money, in anything more the a local club trial, until you came along Dennis, and proved that you could achieve any heights, if you only had the determination to succeed. If only it was the same today!! So thank you Sprite (Frank, and thank you Dennis, to what you have given to our sport of the past. You are both stars, and we will never forget what you have, put into motorcycle trials. Regards Charlie. Edit spelling.

Hi Guy's. Hi Jim, I have now put the nearside photos of the Enfield Cusader, on to the "Otter" site, http://www.bsaotter.com/ It has taken me 1 hour to load the pictures, after trying to update my computor. In the future I will leave well alone, no matter how slow it runs, and stick to building bikes. any more info you need about the bike just ask. Regards Charlie.

Hi Guy's. A Very good friend of mine, who knows about the subject of oil ratios for two-strokes,has just sent me this e-mail. I have posted it. as I think it may help you understand the subject a bit better. Hi Charlie I notice yet more "myths" recently posted on TC about fuel/oil ratios...................and I get the feeling that if this sort of nonsense is repeated often enough it tends to be regarded as wholly accurate fact! In reality any A/C 2T trials motor in good condition is quite happy running on 70:1, but many people dont understand that there is a difference between 2T "synthetic" oils intended for road bike oil injection systems (TTS is one of these), which are diluted by up to 20% with kerosene, so the viscosity is low enough for use in oil injection systems. This has the knock on effect of those who are running ratios such as 100:1 in modern bikes using road type oils, being a lot leaner than whats intended! Seems very strange that a subject as important as this generates so little interest, and that other than my own, none of the trials related web sites provide any sort of accurate info regarding 2T lubrication issues! Obviously its in the commercial interests of the oil manufacturers to keep quiet about the road bike oils not being entirely suitable for pre-mix bikes, but as proper competition oils are available (Castrol XR77 is one) it seems very silly not to use one. Seems a real shame that the net seems to have become somewhere where half truths can become fact so very easily, and once these "facts" have become established, that nothing much is likely to be able to alter them in any way! ---------------------------------------------------------------------------------------------------------------- Hope it help in keeping your two stroke running. Regards Charlie.

Hi Guy's. Hi Jim, I will take a couple of the other side today, I have one of this side but with some parts missing that I removed to modify so I thought I would refit the modded bits and then take some more. Regards Charlie.

Hi Guys's Hi Jon. Yes I have the same trouble, and keep being bol""ted by my bruv for taking things to bits, and then over exagerating the problems why I am not putting them back together quicker. But I do love to play! And there is nothing like getting things right in the end!!! Regards Charlie.

Hi Guy's, Hi Mike. What else have you got in your store cupboard? Regards Charlie.

Hi guy's. Hi Jon. Try fitting longer back units mate it should help, you could go to 350mm. What fork yokes are you using? and how close to the steering head are they? You need to check the amount of trail you have. you could also try and work out what steering head angle you have on the frame. You need an angle gauge for this (inclinometer), With the seat tube vertical. Regards Charlie.

Hi Guy's. Hi Jim, The front and rear hubs along with the forks (modified), came from a "Petite Metisse". The frame was modified (steering head), by a ex works Royal Enfield rider, before we got it. A later swinging arm is fitted, and I made up various stainless and alloy parts, for the frame, on the lines of the Gaunt bike. The engine has a one off alloy barrel, that was discarded by Hitchcocks, for a machining mistake, we corrected this and fitted a steel liner. the rest of the engine (in bits) after I had modified the crankcases etc, was then taken to Ray Tew at Alcester, who is renowned for his work on Crusader engines( he was in the engine development shop at Redditch). He had the head welded re-ported and re machined. Every bearing housing was line bored,etc he also modified the clutch, but rejected the Villiers main shaft and clutch center we got for him. We gave him a new Electrex ignition to fit, and although he had never fitted one before, it came back perfectly timed for a trials motor, and runs like a sewing machine. Nearly every part in the engine was modified in some way by Ray with his vast knowledge and experience with this engine type. All I can say is that if I can get my ultimate C15 engine, running anything like as good as the Enfield motor that Ray built, It will be Good. I still have a few jobs on the bike to finnish it to my satisfaction, and I think it may need gearing down a tad. Ray would not gear the motor down for reliability isues. so it looks like a bigger back sprocket, which is a shame. I will keep you posted Jim, and slip a few details onto the "Otter" site. Regards Charlie.

Hi Guy's. Hi Jim. I thought you would like this photo of the bruvs bike, and you see what you have sugested I have taken to heart. You can follow the hubs progress on bsaotter.com. picture is to big to load on here, so have put it on the BSA Otter site. Regards Charlie.

Hi Guy's Yes that Boy has talent, and a way to earn a fortune, and he will, Trying to find his phone number so that I can sign him up, Before Andy. Can you imagine him writing on here??? Be worse than me and OTF put together for a start. Good luck my son you have cracked It And made a Mint Green Ford famous. Regards Charlie.

Hi Guy's Hi Jim I am glad you enjoy the, bsaotter.com site. You know what I am like, I try to fit to much in. But that is a good Idea! I should make a hub, as I need one for the SQ-Otter project. And I have the privilege of a BIG lathe to use. And yes I would shrink in the brake surface liner, although some are made with Fast threads. So although I have got the ultimate C15 trials engine to build, for the site, I now also have a alloy hub to machine. Watch the space on the Otter site. Mike very interesting how you Mod that hub. Regards Charlie.

Hi Guy's Hi Mike. Well it would have been in the ground before 1965!!!!!!!!!!!!!!!!!!!!!!!!!!! Regards Charlie.

Hi Guy's. This is the clip, it says you need two, but I am sure one would do. Number plate clip, square plate Ref: BF228 TrailerTek Price:

Hi Guy's Or you could , (If you have a big lathe) just get a lump of alloy (correct grade) and turn the complete hub Mike? Regards Charlie.

Hi Guy's Done a bit more homework today. No excuse broken ,plates are illegal and will still get you a fine for display. Plates worn on the back of your jacket , is not part of the machine so when you walk away it is illegal. The only thing I have found that is available, and used on HGV trucks, and trailers, is a Spring clip device that holds the plate while in transit. Now this could be used, all you would need to do is remove the plate to attempt the section and then clip it back on for the next group, Simples I have still been told, that the fine is now

Hi Guy's. I have this week taken two road bikes for MOT. And both of them, have had to have bigger rear number-plates fitted. So does this mean that all motorcycles that are road registered, need this size of plate? I was told it is three points and a

Hi Guy's Hi Totalshell. I know what you mean mate and you totally correct, sept that hunting has finished for the season, and it is totally illegal???? Regards Charlie.

Hi Guy's Check this out and thn you can add your Japanese bits aswell if you like. http://www.amalcarb.co.uk/TechnicalDetail.aspx?id=11 Regards Charlie.

Hi Guy's. Hi B40, You don't realy seem to be getting the point do you?? This is the problem!!!! Regards Charlie.

Hi Guy's Hi Steve. Thanks for that, a true taste of the Sixties buoyant, free enterprise competition motorcycle scene. Take a look guy's ,spritemotorcycles, Youtube. Regards Charlie.

Hi Guy's The last three post's have been spot on. and I have had E-mails today by professionals to this sport. that confirms, that has I say the posts are correct. And also that whatever seems to be the rules for this one trial in the year, dictates the norm for the rest of the clubs for the following year. So we can now be looking at a blanket ban on Amal concentric 1 1/2's, in any classic bike trials for the rest of the year??? (not mine). It is also widely known that Japanese internals are fitted into Amal carbs. and the benefit is that they perform a lot cleaner, but they also cost. Can we now be looking at removing the chain-cases on unit bikes to see if they have Lucas or PVL generators, or checking whether the internals of Lucas BTH mags are not actually PAL speedway items. Then we get on to the thornie subject of the rear suspension units!! should these have restricted travel?? 3 1/2 or 4"? should they be governed by price? and should the length, be as originally fitted to that bike model. and should the angle of deflection be also the same as fitted to the bike model as it left the factory? or is there any discretion? Should swinging arms be restricted to using metalastic bushes or bronze or are we now allowed to use plastic (that was used in the sixties)? Looking at pictures of the first pre 65 Scottish trial it looked as if anything that looked remotely like a bike from the Sixties was allowed! should that not still be the case??? And there has be winners using four stud BSA/ Triumph forks. I must get a life!! Regards Charlie.

Hi Guy's. Well said Woody, Hi Toyboy, You must know my views on the whole situation by now???? And you should know that I have No axe to grind with the Scottish two day trial at the end of April. And has you say if you don't like there rules dont enter (or try). But what annoys me is that a set of rules that is stated in the entry form,( we did know about fork length)? has now been changed within a month of the said trial, For no other reason than I can think of but someone griping to the organisers about certain people using a carb that may be better than the one fitted to there bike, or forks that have better action and movement than there's. This is only supposition. But you now have most of the competitors entered in the event, running around like headless chickens? wondering if, when they get to Scotland there bike will not be frowned upon,and if there will even be more rule changes before the event. But the main thing they will be doing is checking what change they still have in there pockets to perform all these bike changes. Not good for the sport, at this time. Regards Charlie.

Hi Guy's Note Date. Or even one of these. 1962. Regards Charlie.

Hi Guy's. Hi James. Look I am about to do a page on registering a bike for the road, on my web site http://www.bsaotter.com/ If you take a look next week it should be up! Regards Charlie.

Hi Guy's. So why are these not allowed?????????????????/ 1962 Honda CB72 carb. Regards Charlie.
