DTR Build Up
-
We've all been there.
You know sometimes you do have to make the sacrafice for the bigger picture.
I am surprised you're having issues. These engines in stock form are very reliable. Put it this way, you could sell the DT and buy something else as that little toynfor the nice days. But the DT needs to be running else you really will lose out.
Personally I feel that no job is too hard on such a small bike. The most expensive part of the rebuild is the odd sized crank bearings.
The rest is trivial and can be done cheaply. Spread over a few months its like 50 quid a month. And that's if you want it to look sweet. 150 will see a bottom end rebuild stripped and built back up with all new gaskets.
But it comes with its own risks. Gotta do it right and make sure it doesn't fail on you.

@Calum I could probably get it up running again, i'm guessing a ring has just come loose and spun round. But i won't know until i take the top end off. But i just want it rebuilt to find out what the bottom ends like and what the noise is.
But i'm decided on keeping the bike, just fixing it when i get the time. I agree that nothing on the bike is hard, it's so easy when there's a full video on youtube stripping it too. This is just something i need to space out in time, i won't be getting it done in one month at all

So finally caught that bike bug again, always had a hit and miss relationship with this bike the fact that it keeps breaking down. I think i have found my reason why, everytime i take my piston out it is a four point seizure, this indicates running lean. I thought that skimming my head would rectify this as i originally thought it was an overheating issue. However upon closer inspection it is still running lean, i believe some of this is to do with my oil pump. I've got it set all the way in the junction box to the carb, so my oil pump is already damn near full wack at idle. Which is why i eat through a litre of oil in about 2-250 miles and why it breaks, apparently too much oil can upset the Air to fuel ratio causing a lean condition.
So still on a full engine rebuild i've gotten to work, today i got the engine out of the bike and i've fallen in love with working on this thing. Everything is so simple and easy to get to and all using conventional sizes. So in just an hour and a half i've had the bike from completely together to stripped apart with the engine out. Whilst it is off the road i'm going to respray the tank as it has rust holes everywhere that need filling and tank needs respraying.

Not a bad transformation, so cute how small this engine really is. That's my days work done today, was going to sand down the tank and get it primered tomorrow but i'm off with my brother to view a car. Need to order an impact driver so i can take the stock screws out and then with it apart i'm going to clean and paint the engine! Atleast this is what i hope to do, also going to go a jet larger in the main aswell as get the right throttle cable -
@Biker_123 well i couldn't get rid of it, too much work for what i would get back from selling, it's a project after all it's supposed to break and need fixing! That and my student loan turns out more than i expected and i'll be keeping my job every other weekend when i'm at uni. The bike looks tatty as anything i reckon, the plastics are all stained and it's way too plain, i'm feeling some stickers when everything is sorted, make it stand out a bit more.
@Calum Will do, nowhere i could think of where i can get any better advice. There's a complete strip down video on youtube which i must have watched about 10 times by now aswell!@jimmydc98 God knows, wouldn't like to know either. Too much

@Biker_123 Definitely supermoto, i never go off the road really as there isn't anywhere decent round here and i prefer to get the bike over on a nice road! Thanks dude, but it's too plain for me at the moment. But i've got more important things to fix than aesthetics first

Well she's up and running again, I stripped my engine completely and split the crankcases.

Then looked on ebay and found a running engine for £250 plus delivery. So i've bought that and installed it back into the bike. It's from a later 4bl bike and i've found that you can use the later stator with the early style wiring loom and cdi. Just have to change the connectors over! Only thing i'm having trouble with is my speedo keeps turning on and off (koso clocks) So i'll just wire it to the battery. Went out for a rip with my friend who just recently purchased a ktm 125 six days and that is a complete different league in terms of bike. So much more grunt than what i am used to! Still though dt kept up with him at about 70mph but he said he wasn't wide open.

So i plan on keeping this offroad setup now, much more fun when you have a friend to ride with and a bike with an engine that doesn't break. Completely fell in love with it again, however my clutch cable frayed so i had to ride about 8 miles home with not clutch, was quite easy to be honest hardest part is getting goingMy plan now is to rebuild my original engine, new rod, big end and crank bearings. Gearbox bearings etc seals you get it complete bottom end rebuild. Then maybe a 170 with ports corrected Who knows, but next payday this things having a powervalve servo fitted onto it

Nice bike dude. I'm envious that yours is running.

@Biker_123 They're mental, only blipped the throttle in second gear at like 10 mph and it just wants to shoot off! Deffinitely what i would upgrade to.
@Uber_Beluga Don't be envious! As my luck goes this will last all of 2 weeks haha
