Merry Christmas everyone!

@HOTSHOT-III Hopefully the issue gets resolved as I don't want to lose the data they're hosting. The important stuff I ought to host here to guarantee it isn't lost.

Hi all I'm Paul new to here. Recently have a 1988 roundie and sadly the cdi is faulty and the wiring to it is poor so I have purchased another cdi and re-bulleted the connectors. I have a green/blue wire from the cdi left over? The bike starts immediately but the revs are really high very like the common schoolboy error of putting the slide in the wrong way. It currently has a flatslide fitted but I'm destined to put a roundie on to get back to original spec. Anyone help?

@Calum said: These were almost a nightmare to source 16 years ago, I can't imagine trying to source one now. My bike was stolen in 2010 and they smashed my headlight, the only one I could find at the time at one of the lugs snapped off. Looks like there is one for sale on eBay: https://www.ebay.co.uk/itm/117220896053?_skw=DT125re+headlight&itmmeta=01KTM8B5217RAZTYS7W99928FR&hash=item1b4ae8ed35:g:y7gAAeSwpAdqHbG7&itmprp=enc%3AAQALAAAA0GfYFPkwiKCW4ZNSs2u11xBZmLIU--K9J71U9lN1jJvKGElmcMKBjUzhn5JV3gvFr%2BI2mNwns0SlbUycS%2Bw9y3Qsk%2FC9Cp56dPrHcSEz%2FAr0Zq5el9BEEdpE--23lnRC8fU0%2Fsn13ryM871mf1jmM1dUjkmiSvaLNgJjb67pd3KfdVjuND8nPx720y4ajz9BPqgS8GUW%2FCNLpWF1MTDMkYcIXC7cHLcpOan7woIP1A2k2vjESEOPdlk4W2oy4yUcxyO%2BXWy347GqH%2BHrWnu%2F2Og%3D|tkp%3ABk9SR5bRrIjVZw Looks like there are some copies on eBay as well: https://www.ebay.co.uk/itm/188014865985?_skw=DT125re+headlight&itmmeta=01KTM8B521KCQCFP6HVFB9B97Z&hash=item2bc68f2e41:g:v4oAAeSwOt5pf0Q6&itmprp=enc%3AAQALAAAA8GfYFPkwiKCW4ZNSs2u11xBGAd3jIpQ1I%2FPeoct0WRAbZx%2BSpsbDaUmQIjZgqRPgUJo7nG5bGWKGBRZtJJ4k6kWqRTJdLi2QjCbWA%2FBE6jgcnSjbxqmpxc5alD7AkePHPryhwNx3wJMQx9Nn2c%2FJBb%2FaX0A7Z%2BlEzJ6pVoqrlh3sZUh2UZ%2BqkVZwe2vBfwA2F39HuV9O1D2z%2FSIMHbNWWFAOiiE%2BG%2F8xlRqkrAHFOwt3oKAIwYBpeHVG82hZBHdODyJwGkKG5Ef9gkphJk0fgSnlvoW%2FpV6wkCrHIDEqggbFJ3LfV5W5qwYpTWvJNjb1RA%3D%3D|tkp%3ABk9SR5bRrIjVZw Thanks for helping and sorry to hear about the theft/ damage. I had a different bike stolen around the same time period and wasn’t so fortunate with them burning it 2 doors down in a wheel barrow - I can only assume the chain & locks were giving them trouble. I purchased the unit from the first link as it’s stock and doesn’t look in too bad shape - I’ll hopefully be able to do some sort of refurb with the damaged unit I have right now and keep it as a spare now knowing their scarcity. Thank again! - one step closer to getting her back on the road.

HI Chaps, Advice on my predicement please, Built a 2003 DT125R last year, with an athena 170cc kit and Full athena exhaust.. life gets in the way and its only this year iv got it out and ran it in, this is a full nut and bolt rebuild, new crank and internals etc.. specs 2003 DT125R 3RM with a 3RM-20 CDI, Athena 170cc Kit Full athena Exhaust, standard 28MM Carby with 290 Main and 25 Pilot. Inlet reeds are carbon fibre Yambits Jobby. under load or with no load it will not rev past 9500rpm like its hitting a rpm govener like a chainsaw.... iv upjetted and down jetted 270,280,290,300,310,320,330,340 all the same blocked off powerjet and with powerjet etc... powervalve is visually aligned up the exhaust port and functioning, but have all so tryed pinning it open, visually confirmed. same thing.... The Baiscs, new plug, new ht lead,coil and cap, jets as above, snorkle in snorkle off, powervalve pinned and with YPVS. Reed switch behind clocks is out and tucked away out the housing. my only other thought is to reduce the plug Gap, but seeing if anyone else has seen this or had exprence with the 170 kit any advice aprecated, Cheers

Oh okay interesting, are you able to fit a kick start and ditch the starter motor? The DTRE has a starter so maybe that frame is a better fit.
