Manor Posted April 16, 2013 Share Posted April 16, 2013 Hi everyone, new to the site, so be gentle Just picked up a gleaming 1989 TZR 125 (fully rebuilt) and wow lovely bike. But.............................Errrrrrrrr!! Will only tick over once warm, and then (when blipping throttle) sits at 3000 revs for a few seconds before slowly running down to 1000 and rough tick over. Rides well up to 7000 revs then splutters and pops as it tries to go into the power band, but refuses to budge past 7000revs and 60mph. As i understand it the power valve is pegged open and it has a Ginelli exhaust. I have tried to ring Stan Stephens, but he is on hols till the 30th April. Any thoughts or help would be really appreciated. I live in the West Mids. Cheers, Manor Link to comment Share on other sites More sharing options...
Moderator Cynic Posted April 16, 2013 Moderator Share Posted April 16, 2013 Ok. Not really an into as such :-). You say fully rebuilt. By who, when ? Are the important questions. Follow that with whats your skill level with the spanners. And is this your first bike. Gut feeling is carb. If that pv is pegged wide open it should be horrible to ride. But if someone has it backwards or its still on the stock 200main it will run out of puff at around 7k. More than one small issue spoiling a good bike i think. Be interesting to know what main jet is in there and what pipe it has. Pics would be even better.... Oh and welcome... Link to comment Share on other sites More sharing options...
