Did you track any down as i could do with some

are you sure that one fits a TZR50 as its advertised for fitting a 1981 DT50 totaly different engines

Hello all. Just joined so I thought I would say hi before I start asking for help. I started my motor biking when I was 16 with a Yamaha FS1-E 50 in 1998. I went on to get a TZR125 and I loved it. Sadly I passed my car test and neglected her and ended up selling her in 2000. In 2002 I ended up acquiring her again after her owner crashed her into a wall. I spent a few months restoring her. Then I ended up getting married and she got stored in a container in my mates work and ended up getting stolen or lost and she hasn’t been seen since. I lost interest and never ended up doing my full test and thought my biking days was over. Which brings us to 2012. About 8 weeks ago I got offered a Yamaha YN100 neo's for very cheap but it wasn’t running, now my intension was to get it fix it, MOT it and sell it. Soon as I go its spark back and got it running I seemed to get my spark back. I got insurance and booked done my CBT again and then I was on the road again. I ended up buying a TZR50 a few weeks ago that needed a bit of work but I was happy with it. I know it’s a bit of a drop in power to the TZR125 but I can ride it on my car licence with no L plates and also carry passengers (my kids) as it’s classed as a Moped. I am going to do my test now and get a R1 but in the meantime I’m happy playing out on my TZR50. Iv just got a 90cc bore kit, technigas exhaust and carbon reed valves to fit in the next week or so and am just looking for a bigger carb. Well thats me for now. Im a bit out of touch with bike engines these days but ill help where i can and ill pick it all back up soon enough

I had similar problems with mine at first. Have you changed the Plug - Mine looked fine and seamed to spark fine outside the head but it just didnt work properly. A well as the plug if could be the Coil pack, lead or cap causing lack of revs. Have you stripped the carb down and checked main jet size - my is stock and someone had fitted a #125 in and they only have #88 in as standered. Change the Fuel filter and fuel line - My filter was blocked and lines was corroded . It might be none of the above but thats what i had to do to get mine reving properly. Mine only revs upto about 9k im not sure if thats right but i runs fine

Sorry to jump posts but did you sort out your issue as I'm facing a similar problem.
