  Hi @barron-1989, Great little project you have there. Looks as though it's coming together nicely now. Haven't seen anything on the For Sale section for years. These days it seems like FaceAche is your best friend here. The sale sections are not visible to members below a certain post count mind you, although I haven't looked at the settings since I set this website up over 10 years ago. These are cracking little machines, it won't take you long to get her ticking over nicely that's for sure. What bits are you after just out of interest?

  @hotshot-iii hey, before assembly i adjusted the float height to 16-16.5mm according to the maintenance manual. I went through all ignition related cables and switches but nothing out of the ordinary. No corrosion etc... Also installed a genuine replacement coil and measured the primary and secondary winding just to be sure haha. The plug chop was done at 10k rpm. Did it a lot with mopeds to check if the main jetting was right. Today it was less hesitant to pull through so it went better when i just gave it full throttle from the go. This was after i finished the idle configuration with the screws. Steady +-1.6k rpm like the manual says and the air mixture screw is just about right. Temperature is very stable +-70 degrees celcius and its stay like that after driving almost an hour long. Im suspecting 2 things that are happening, correct me if im wrong haha. 1st thing is my powervalve that is opening a little bit to slow, i feel if they once open up, i can hear it and feel it and i can give them beans without any problem. Tohe other thing is maybe im running too rich in the lower rpms?

  Could be a lot of things.. but everything is probably not as it should be if it's not starting.. What I can think of: -Leaky crank seals -Damaged/leaking reed/intake -Carb issue -Ignition angle off (flywheel key?) Is the spark plug wet? Is there a good suction pulse from the carb when kicking it? With some experience you can feel it if you cover the carb with your hand on full throttle while kicking/cranking the engine. It should not blow, only suck, and the pulse should be 'strong enough'. Old fuel can make it hard to start too.

  Hello @chalcosoma, Apologise I didn't get around to replying last night. You can get away with running some pretty aggressive tyres on the stock rims, my friend once went very savage on his DTR (to the point spokes to breaking left right and center ). Sadly, I am not that clued up on tyres and availability in the States in general, but I certainly would have thought this wouldn't be a hard problem to solve. It would be interesting to hear what other people have run in the past as I know quite a few members had TDRs.

  Frame looks same bottom end on tht looks like the dtr engine I have my 4hw has no cover over the oil pump and has some kind of make shift bracket for the oil cable. Looks like they chopped my frame and put a heavy duty swingarm on for that 4DL raised the coolant tank and put bat under the seat. Thats why I asked cause surely the 4 wires from the engine are the same or do I have to change the flywheel coil bit of forget its name now. I think i'll give it a bash as I got to remove the engine anyway if the mountings are the same and it wires up maybe I can put a DT rear sprocket on. Food for thought ive got to get the energy to get at it first i'll look over that cdi wiring diagrams thing you shared and go from there just hope the exhaust mounts dont throw it out of whack. I'm hands on so once got all the parts in sight i'll hopefully make sense of it all feel free to leave suggestions etc like I said before wish I had someone here to help me out going to be fun though so hopefully will give me more incentive.

  Slow slow progress on this. Made a bit of a push on this the last couple of weeks. [image: chainFitted.jpg] New Renthal chain fitted. Bought some nice Apico foot rests and refitted/bled the front brake system. No surprises, but the original brake caliper was shot, completely seized solid.I managed to source another one, but one of the pistons was stuck. Once I addressed that, I found I was unable to pressurise the system, the master cylinder was shot. These bikes share the same master cylinder as the Cagiva Planet, but I was unable to source one of those for a reasonable price. I ended up getting a KTM Duke 390 front master cylinder as the closest match I could find. Front brake now bled and working. Bought lovely Hel lines front and back. The rear master cylinder's wiring loom was shot to buggery. The banjo switch was all snapped and the wires were merely soldered onto the bolt. A new genuine bolt, wire harness restored, then I designed and 3D printed the cover to secure it all into place. [image: banjoBoltCover.jpg] Need to reattach the rear brake master cylinder fluid reservoir and see what surprises are in store for me for the rear Hoping to continue to make progress on this as it's basically done. Just need to find original panels (or refurbish my ones for now).
