    Hi there Just bought an ignition tune up kit for my sons Whitehawk 80 and when refitting, I think it may have been wired incorrect previously (or I'm wiring it up wrong !). This is how I think it should be - hopefully someone can clarify ! Main ignition wire from coil into stator plate is joined 3 way with the stator coil wire, and a wire to condenser. Condenser then has another wire to the points. Hopefully this makes sense ! cheers and thanks in anticipation for the help cheers John

    Have seen on some ty175 they have replaced factory starter arm with a al one! Does anyone know what they used ?

    Am I correct in thinking that the TY175 and TY250 share the same hubs and brake components?

    I have a friend with a mint original TY 125 looking world wide for a mirror ( Round, chrome and stem ) . He has had no luck sourcing in France, could anybody point us/him in the direction, preferbly the Uk, if not further afield. Apparently these were particular to the Ty range unless anybody knows different. Thanks

    Got a friend with an untidy TY Mono. Had a little look over it the other day and the front end is way to hard, its got two different spring types fitted: one nice and soft, with a spacer like the manual and the other with no spacer that feels like its from a MXer. Any ideas on what could be used as a replacement ?

    Hi there, Just been given the above from a neighbours garage & would be grateful for a few hints.I have sent off for manual but would like to get a little further without waiting for it to arrive. Managed to get motor running after thoroughly cleaning out carb - bike hadn't run for over 10 yrs - but would be grateful for any info on carb settings. Any clues relating to the 4 position ignition key - what does each do? Also what is spec. & amount of gearbox oil required? Any info gratefully received.

    Hi all i have just got myself a Ty mono after looking for one for ages and its great.I had one about 17 year ago but cant remember how much engine oil goes in,off the top of my head 800ml seems to ring a bell or is it 600.And what oil is suitable as its had ATF in it.Also what 2 stroke is best, i run my GasGas on castrol tts the guy i bought it off said he was running rock oil fully synthetic 85ml to 5 ltrs.I will have loads of questions to ask in the future,but for now i am just going to ride it & enjoy.

    I've had my TY 175 for a few years now, but the other day I decided to put the lights on it. everything works fine apart from the brake light, that's powered from the yellow wire, it's came off the coil and I can't figure out where or how it goes back on from the wiring diagram in the manual any help would be great, Thanks

    Hi all Apologies for my first post if it's in the wrong section. I am wondering if the crankshaft seals can be replaced on a TY175 with the engine in situ, or is it necessary to split the cases? Any hints or tips would be gratefully received. Alan

    Hi I have been thinking about building a Mini Majesty for some time, and have the TY parts that I need. Is the Mini Majesty frame smaller than a standard TY175? (and suitable for an adult rider?) Does it really make much difference to the handling characteristics? By how much should the swinging arm be extended? Has anyone had any problems with building one, or issues with owning it?

    I have just completed the rebuild of my 320 Yellow framed Majesty. I was very suprised at the huge gap between 4th gear and top. I was wondering if this is normal? Any info would be welcome. How do I post a picture on this forum? I would like to show her off!!!

    Hi, Can anyone give me the standard specs for a ty80 carb ? Jet sizes , pilot screw position , and especially the needle number as i dont think it is the correct one. it supped about half a litre of fuel in a couple of minutes ( cant be right ) !!!! Just put this back together from a complete wreck that some kids had been ragging around as a field bike. Nice little machine now but seems to be running way to rich ! Also any idea where I can get a needle from ? Many thanks Jim.
