dpmotorcycles Posted February 8, 2011 Author Report Share Posted February 8, 2011 Have you checked the woodruff key ? yes its fine and i re-torqued and screw locked the nut when i replaced it any more ideas Pleeeeese Quote Link to comment Share on other sites More sharing options...
nevilletanner Posted February 8, 2011 Report Share Posted February 8, 2011 need to work out if its electrical or fuel .... this may not be the best way but it works for me .. poor a couple of cc`s of premix petrol into the air path ( air box or in the connector between a/box and carb) kick the engine a few times and see if it fires .. if it does then go for carb or reed valve or air path leak/blockage(stuck float bowl is common as is a crudded up air filter) if it still does not fire then its elecrical , check earth points (make sure there not furred up between the connector and the frame) has it got the right CDI, theres 2 different ones on the technos, where did you get the stator rewound ? if it was WCW then it would be a ducati cdi unit if it was steve in spain then drop him a email and he will tell you which system it uses. are the wires connected up properly, i have seen one where the +DC was sent to the cdi instead of the required +AC. is the timing plate in the right position (behind the flywheel)? hope this helps.

With regards to the postion of the timing plate, what is the correct postion? how can i check its correct location?, i have it screwed down in the centre of the slots for the screws. If the wires are wrong then surly i would not have a spark, is this correct? Is it possible i have a air leak in the crank, would this stop it starting? Is there a mix of fuel the beta runs best on?

Paul WCW do only the ducati stators , so thats ok timing plate set to middle of slots is the same as mine. if the wires to the stator were wrong you would only get one spark as the current start to flow and thats it air leak at crank ... take off the carb, cover reed inlet with hand and see if there is suction, there should be. if there is pressure there then the reed valves are not shutting and would need to be sorted out. never heard of the crank leaking but surpose it is possible , try runing some washing up liquid around the center of the crankcase (where the gasket is) and see if it bubbles if so then the gasket has blown. internal gasket i would have thought could be detected by pressure at the engine oil filler hole (dont quote me on this but it seams logical to me). the mixture ratio for fuel / air not sure, but wind the mixture screw all the way home then unwind it 1.5 turns .. that should be a basic setting to get it running, sure some one will but in if this is wrong. you have checked for compression havent you ?

dpmotorcycles Posted February 9, 2011 Author Report Share Posted February 9, 2011 Hi, yes compression is fine, intact we got it running tonight, the crank was full of fuel, we tipped it up side down drains the crank and it fired up. This has now shown another problem it will not rev. We have tried it with and without exhaust no difference, tried moving the timing no change, cleaned the carb again no change, changed the plug no change. What we have noticed is the reading from the coil when testing with the meter are different to other coils, does the beta one work in a different way, how would you test the coil? What reading should we get? To sum up we have fuel We have spark but not every time when kicking by hand Clean air coming in No blocks going out My fuel to oil mix is 5L petrol to 100ML oil Any advice to why it's not building revs?

Cheers Paul great news, when my bike had that problem it turned out to be the stator, but as you say that it has been rewound and that the crank was full of fuel .. double check the float bowl height, this could cause it to pass to much fuel hense the fuel in the crank and possibly not reving clean as it would be the same as having the choke on, check the choke is operating properly - same affect as above. sd to the coil :- Coil Testing This another subject where you find different test figures, basically test between the two spades the reading should be 30 to 33 ohms from the ht lead to the steel bracket 5.6 to 5.8 K ohms. There is talk about black and red leaded coils what will run what, when I talked earlier about diodes in circuit this is where it comes in, all the stators that ran diodes were early stators and ran with a red leaded coil, these red leaded coils will only run with a diode in the stator, but the black leaded coil will run either, but I have had red leaded coils run both as well so watch out. If you need any other readings which are not mentioned or any other problem you my have just send me an e-mail.

(AS STATED BY STEVE AT http://www.uk-motoplat.com/testing.html thanks for that again, i have sent the information to motoplate to see what they suggest, i have also just bought another techno which i am going to use for parts, i will change one bit at a time untill i find the fault, might be abit extreme but hayho! when i get a result ill post the info. i did contact beta for a new coil these are Quote Link to comment Share on other sites More sharing options...

nevilletanner Posted February 11, 2011 Report Share Posted February 11, 2011 (edited) well the seller of the doner bike pulled out of the deal at the last min so it looks like it back to the drawing board. Seen as the coil does not give the same result as other coils i have tested of different bikes i will start with a new coil from "Beta lampkin" finger crossed it here tomorrow if i have no joy with it then i am sending the cdi and stator over to motoplate to have them tested. Ill keep this topic running until i have a working bike. theres a couple of coils on fleabay at the mo .. not sure if a rev3 one will work on a techno. might be a idear to look through the members on here and see if there is some one local with the same bike, message them and see if there willing to swap bits about until you locate the prob. i would do it but your a good few miles from me.

I checked the bay, there is nothing there for me, most of the beta techno stuff for sale on there is mine lol Quote Link to comment Share on other sites More sharing options...
