    @SpookDog said in Cylinder/exhaust problems: I’d be interested as well, specially if you have the head to match... Me? If so shoot me a message bud, they all match and they’re even the same pair that come together in Italy nearly 30 years ago

    @jonne123 as long as you put the 750 in and didn’t leak or spill any it’s fine

    Thanks for responding! I tried to unplug the killswitch, but nothing happened. The side stand switch is unplugged. Where is the fuse? Is it with the battery, cause i dont have a fuse there.

    Ok. But usually non restricted 125cc bikes the exhaust just moves the powerband. makes sense.

    Ive been off this forum for a good few months now but I went through a lot of tuning with a Polini PWK 32mm on my DTRE. On standard engine it took a lot of jetting and needle changes to find one that worked but when it was done it had a little more torque than stock. I had plans in the pipeline for a new engine build and programmable ignition which is why I changed the carb, my engine was worn out when I tried it at first but it does work and go well, you'll need to adapt your throttle cable. I have now built my new engine up with ignitech ignition and advanced map, carbon reeds etc and it needs rejected but goes very well, unfortunately I haven't had the time or enthusiasm to go on any bikes since spring last year but if I get round to it this year I will finish tuning the DT and write more on here, I have wrote some stuff about the polini carb on here before, I'm not sure if you seen it or not.

    As I have finished the 1988 bike looking for something to do. Seriously looking at doing this to keep me busy. I'll have to look around and see if I can find the parts needed. Nice job!

    @jonne123 i mean it depends on you. if you want to mix oil yourself then go for it. but i haven't heard of those oil pumps failing
