Ed.laza the speedo didn't work when i got it so I have no idea how many miles it's done! It only said 4000kms! Compression is good and I got a new cylinder/piston/rockers about a year ago so they SHOULD be ok. I will get the tank off then and check the valves for leaks. The air filter and brakes are ok.
............ The carb could be an issue. Took a look at the plug and it seems to be running rich. I have a 100 main jet and 27.5 pilot in there to match the exhaust/K&N. And I live at approx 3000ft but performance up to 5500 is important. I've heard of dropping the needle by 1 notch and opening up the air screw. Is there a way to tune the Main Jet? I don't think this is the main issue though. The bike had the same problem before I fitted the new carb and jets.............................Mine also will absolutely not cruise happily at 65mph! 55 is about the max for cruising and probs 65 flat out................. Ric, it's a shame you found the TDC tool inaccurate because unfortunately it's the best I have here. The only other option is mechanics who just do it by 'feel' :S.............It's very interesting to hear opinions of it's performance with relation to other bikes. At least this is a sort of benchmark to aim for. I know the KTM 200 well and never had any hopes of matching it for speed etc. Like you said it's a very different bike from a different era. The story from stinkwheel of being overtaken by a C90 made me laugh. I really hope it was the 125 version! At least now I can start to think of the power in terms of a 125. Although at the minute the torque seems to be the problem, bullets are meant to be fairly torquey (rather than bhp) machines but at the moment it feels like there a hole underneath it where all the torque just falls out!
