trials1951 Posted December 5, 2013 Report Share Posted December 5, 2013 Hi, can anyone help me with any information or photographs of Wasp RT4 with Villiers engine circa 1964. I am in the process of rebuilding a RT4 and this information would be most useful to achieve the correct period look. Quote Link to comment Share on other sites More sharing options...
norman_wisdom Posted December 5, 2013 Report Share Posted December 5, 2013 Oddly enough, a quick check on their (new?) website reveals this very bike to be back in production, complete with a few period photos, though I'm sure they would help you with some more if you contact them, http://www.waspmotorcycles.com/wasp%20trials%20solo.html Quote Link to comment Share on other sites More sharing options...
trials1951 Posted December 6, 2013 Author Report Share Posted December 6, 2013 The Wasp Motorcycles website was indeed my first port of call and there are two black and white very grainy images of Wasps one of which shows Geoff Chandler riding a Bultaco engined one. I did contact Wasp directly and they could only supply me with the approx. year of manufacture from the frame number and who it was sold to (Mr. Hyland). They have not been able to give me any further information. Quote Link to comment Share on other sites More sharing options...
norman_wisdom Posted December 7, 2013 Report Share Posted December 7, 2013 That's a bit of a shame if they haven't got any more period photos. Should make a great project, be good to see some pictures of your progress. Quote Link to comment Share on other sites More sharing options...
feetupfun Posted December 7, 2013 Report Share Posted December 7, 2013 There are clear period photos of Bultaco Wasps in "20 years of twinshock trials" volumes 2 and 3 Quote Link to comment Share on other sites More sharing options...
jc2 Posted December 8, 2013 Report Share Posted December 8, 2013 How about some pics of your bike? Here's a couple I found on the net. 1 Quote Link to comment Share on other sites More sharing options...
trials1951 Posted December 12, 2013 Author Report Share Posted December 12, 2013 Some photographs of the project so far. The front (Tiger Cub) has been rechromed at Niphos and they have also polished the rear(REH) hub, the fork stanchions were hard chromed by Philpotts. Can anyone tell me if there were side panels originally fitted, as the brackets present would indicate, and were they GRP or alloy?also type of exhaust? The engine is at present being rebuilt, will take some photos when complete. 1 Quote Link to comment Share on other sites More sharing options...
laird387 Posted December 20, 2013 Report Share Posted December 20, 2013 Hi, Add an actual period shot - again by my old mate Gordon Francis showing Geoff Chandler on his Wasp in 1967 (I think !) Quote Link to comment Share on other sites More sharing options...
trials1951 Posted December 21, 2013 Author Report Share Posted December 21, 2013 Thanks for the period photo, much appreciated as it shows the exhaust system. Are there any other WASP owners out there?? Quote Link to comment Share on other sites More sharing options...
340villiers Posted December 22, 2013 Report Share Posted December 22, 2013 (edited) Hi Trials 1951. I am the owner/builder of the alloy tanked Wasp above, The picture was taken at the Alvie Two Day Classic early on this year, It was not quite finished, but i was keen to get it out. Rob Rhind Tutt Dated the frame as 1963, The Wasp Trials frame kit was completely overtaken when the sidecar moto cross models really took off. There are very few original models left, I was surprised when I seen your's for sale on ebay very complete, Keep up the good work, you really are making a cracking job so far!!! With regard to my own one, I had built a 340cc Villiers motor some years back, I had the opportunity to obtain some Dot barrels in a completely raw unmachined state, this got me thinking about building a big Villiers motor (These are NOT the Big Factory 360cc MX barrels) these were unsuitable for building up a trials motor. There was/is a lot of negative crack about Big Bore Villiers conversions, they where so radically ported, very few worked well as scramblers and even less as a trials engine.As for the (after market ) alloy barrels most have been tweaked in some way!!! What I had was the chance to start again and produce a big bore barrel that I ported very softly. As for the bottom end this is a complete Alpha crankshaft and crankcase's, I used these because of the size of the crank flywheels (huge for a 2 stroke), no external flywheel is used in the Alpha set up. I have added another 6 1/2lb to the end of the crank and fitted a Electrex World Ignition kit (this was the first kit they produced). The torque that this engine produces is outstanding, it is completely predictable, and it grips for Scotland. I have put a lot of work into the bike, but thats all part of the fun!!! or headache!!!!!!!!!!!!! If you need any help just ask. Best Regards Willie Stewart Edited December 22, 2013 by 340villiers 1 Quote Link to comment Share on other sites More sharing options...
laird387 Posted December 22, 2013 Report Share Posted December 22, 2013 Hi, Willie, There was one 'big-bore' Villiers conversion on the market, the brain child of a lad called Burns (sadly my advancing Alzheimer's is hiding his first name from me). He worked at Moto-cross Motors in Oldham and sold his developments as a kit. I bought his own bike from him, in a Cotton framed sidecar outfit, did my own improvement to the ignition and eventually rode it as a solo. It was far more like a fourstroke in power characteristics, pulled like a train when you put it in a higher gear and made it work! I swopped it eventually in a deal for a new Greeves Pathfinder - and that cured me and pushed me back on to fourstrokes in a hurry!

wacky Posted January 11, 2014 Report Share Posted January 11, 2014 Regarding the big bore conversions produced by Johnny Burns. These were originally produced for Scrambling and I think I am right in saying Chris Milner of Chesterfield was supplied with one to develop for Trials.He had it fitted to a Cotton. Mick Andrews assisted him trying various additional flywheel weights etc. and changes to the carburation (I think he ran an Ossa carb.). I can't remember the outcome but Chris was soon Ossa mounted via Eric Housley. Sorry if this is not 100% correct but we are talking nearly 50yrs.ago Quote Link to comment Share on other sites More sharing options...
laird387 Posted January 16, 2014 Report Share Posted January 16, 2014 Hi, Seen regularly riding my British Bike Championship was this Wasp, ridden by Roy Trump from South Wales, This image was from 1992, taken at the last Cwmcwefru section of the Frank Jones round of the championship. Enjoy Quote Link to comment Share on other sites More sharing options...
hillary Posted January 16, 2014 Report Share Posted January 16, 2014 Laird's December 20 posting showing Geoff Chandler is, I think, incorrect. I think it is of Arthur Dovey but I'm happy to be corrected, just my opinion. Quote Link to comment Share on other sites More sharing options...
sparks2 Posted January 16, 2014 Report Share Posted January 16, 2014 (edited) No, sorry it's a very young Geoff Chandler. What's the head and barrel on the B/W Roy Trump picture above?? Edited January 16, 2014 by sparks2 Quote Link to comment Share on other sites More sharing options...
