Hi i have a 1990 yamaha dtr 125 rides and accelarates great but gets to about 70mph at about 8 -8500 rpm then will not go anywhere and the engine is absolutley screaming,ive looked behind the clocks for the 'reed switch' rev limiter? And there isnt one there also looked for the 'black wire with green stripe' to eath behind clocks and cannot locate this either do the 1990 models have a restricted cdi or any different restrictions? i have a full dep exhaust system on it any help would be much appreciated tried looking on dtr.net but it just redirects me to google pages thanks in advance guys

happy riding .danny

Ever thought about a bigger bike.

 

Yeah i have the dt is just cheap and cheerful just wanted a little more fun off road
