H reg Dtr



  • Bought my dtr about 8 months ago as a spares or repairs. The original idea was just to get the bike roadworthy and use it as a daily. But after finding bodge after bodge on the bike it soon turned into a full rebuild. Bike was stripped to a bare frame. Brakes, swing arm and forks rebuilt and the frame re powdercoated. Bike sailed through its mot in feb, but was never quite happy with the engine so decided to rebuild it myself, and thats where the bikes currently at.

    sprocket nut had been fitted with out lock washer, wouldn't undo with airgun, so had to be split with drill and chissel.

    .5 oversize piston, which turned out to be undersize for the bore, explains the piston slap when cold 😲

  • might also explain the markings in the bore

    rest of the engine came apart pretty easy

    I've had the crank rebuilt and barrel rebored, and have bought all new bearings for the engine. Just in need of a intact power valve cap and temperture sender (engine has the warning light type fitted). Then can start building the engine up, when I get some spare time. Also looking at fitting road tyres to the standard dtr wheels, if anyone has any recomendations on size and make? Cheers John.

    Thanks calum, original plan was just to derust a few spots and touch up with paint but that plan soon went out the window lol.

    I had the same issue with that sprocket nut too. Main problem was that I had already taken most of the engine apart.. Took a good couple of hours to get that thing off in one piece!



  • Yeah unfortunately that nut is connected to the output shaft 😮

    I wouldn't want to be hitting that with a hammer and chisel personally!!

    Especially as that thing is going to be rotating at some silly speeds during operation.

    With the nut drilled out, your only chiseling through about 1mm metal, with a nice sharp chisel it takes surprising little effort to split. Your tapping it rather than clouting it with a hammer.



  • Oh good. I thought you were chisling it all the way through lmao. That would not have been good lol.



  • @Calum would be quicker to chisel to the centre of the earth lol 😂😂



  • @DTR+NSR Nice work so far mate, keep it going!!! 👍
