Good pictures definitely. Measurements possibly. Not sure how i'd go about accurate readings. I've only got verniers.

Passed my test mate thanks haha. But nah it's not about power. It's about delivery. I don't even want that much power. I'm just doing it because i can. It's good fun and it will be i teresting to see what you can get out of it. I'm aiming for low 20 to 25bhp. More than that and it just won't be any good for everyday use. My intentions are to have it dyno'd at the end.

Cheers mate. Would have finished it off today but forgot to buy tab washers to put the primary drive gears back on :~( And they can only get them ordered for like 1st January .Ah well. Always next year haha! Will try and get as much as I can done now. Got to put a kickstart on this TZR yet. Luckily already bought so can fit that. Generator needs puttng on. Got plenty to keep me busy. Bought new clutch plates and springs. And carbon reeds. Just want this to be a brand new engine for when it comes on the road

Okay. It's been a long ass while but finished work for the rest of the year now so have spare time to crack on. I've been worried about this part for a while not....not sure why? It was surprisingly easy and satisfying. Can't say whether it works or not. It seems to select gears and the crank rotates. So that's some. I genuinely thought it would take longer to do this than it has. Just followed the Haynes manual and working through it slowly and carefully. Seems legit. I only stopped because I actually have reached the point whereby I'm putting it back together but don't have all the new shiny bits for it yet. So that's new. Nuff the talk here's some pictures. Gently tapped the rebuilt crank in. I have been so worried about this part ^^^^^^^^ Wondering how I'm every going to put that back together. Well I cable tied the gears together BEFORE I TOOK THEM OUT. Seemed to work a charm. They dropped straight in no problems. Then the forks... well that was a little tricky to get my head round cause I for got to take photos but Haynes explained it very well. THANK GOD! Getting these little bastards in took me a while to realise that you need to remove the support first then put it back in once you're happy with it. Advice on how tight those crankcase bolts should be? My torque wrench doesn't go down that low. So I just did them fairly tight but not too tight? Bit worried about that actually. So here's where I'm at so far. Want to put carbon reeds in there before I put the inlet back on. So will have to wait. Also want to put a new clutch in there as well. So need to order one of those. Will try and finish the majority of this off this weekend. Then it'll be the interesting stuff. Need to take the cylinder off my bike. Send it to a tuning specialist. get some sexy work done to it. Back it on this bottom end. Sort the carb out. Got the VHSA 32mm Delorto (4DL Carb). Sort out my Zeeltronic. Run it in then Boom. Summer tears! I'm thinking of running it in using the 4DL cdi first. Then switch to the Zeeltronic. Got a pre 96 airboot new from Yammy. This will be heated up so it can take the bigger carb I have already got one but it's startin to perish.

Haha those indicators are ace.

Dem shoes too! haha

That's rapido! Like the use of helmets there

Mate the Aprilia SR50 was a feat or PURE INGENUITY. The later ones ran fuel injection on a two stroke. Okay it was an utter failure but still class! If Aprilia sorted that out we would be in a completely different world right now! My mate had a trekker. Slow as shıt but a good little bike. I like the idea of buying something for £35 and spending as little as possible on it. Is it possible. Surely your costs will just escalate?

You're better off taking that initial £270 and building it yourself by the sounds of things. That's what I've been doing.

Yeah she looks mean with those fat wheels between the swingarm.

Stupid game took me ages!

Also my advice is to return it back to autolube. That's the best thing for a road bike. Ensures the engine gets the right oil at all RPM's

Aww man they do look sick in yellow. I done an rs supermoto conversion. Good.

Spoking wheels is an extremely tricky job. Fair play for giving it a go.

Oh dear. This one has seen better days. That cylinder at the top. That's coded 3BN. From what I understand now they are not that great of a barrel and were quickly redesigned to make the 3MB barrel. If I were you I'd swap it over one of them. HOWEVER I don't think it's that simple. The 3BN has slightly larger bore and thus it must have a shorter stroke. You will want to use a thin base gasket and make sure you buy the correct piston size. Starting at 54.00mm. If you decide you are keeping the 3BN cylinder be SURE TO GET THE RIGHT SIZE PISTON! Sizes start at 54.40mm. Damage looks like oil pump failure causing lack of oil. Or maybe (although unlikely) they didn't recognise the bigger bore diametre and bought the wrong size piston causing insane piston slap and then ultimate failure. Although as said by the looks of things i'd put my money on oil pump failure.

Very unusual to see a girl doing a motorbike project. I'm impressed. Seems to be going quite well. You must have a lot of patience to be doing all that polishing. Especially on those bolts. If it were me I'd measure them all then order a stainless steel kit off ebay, Won't rust as easily that way and will stay shiny for longer. If you took your time with everything else on that bike it will be an absolute minter. One worth saving me thinks!

Sweet. Got the crank back today. Very pleased with the price to rebuild it. £20 at a Yamaha Dealership. What a bargain! Technician said that the crank didn't have too much life left in to it due to some scores to the big end eye. The bearing was about to spin :\ All done now. Needed to machine down the wossner connecting rod since there are no aftermarket belgarda con rods. But jobs a goodun and i'm well pleased. Saves me scrapping an okay crank.

Can you really put a price on saving ya neck? Not really. Worth every penny IMO.

Haha. Nah keeping the headlight. It's not the old shape. It's the last DTR shape headlight. Personally I like it and then it's the question what do you want out of the headlight. Decent visability or decent looks. If I only used the bike in the summer and only during the day then that question answers itself. But unfortunately it's an everyday bike and thus needs a good light source. May consider aftermarket light in the distant future though. Fancy one of those angel light ones lol. Audi style I haven't examined the gearbox yet. I will have a good look though. Even though I have no idea what it is I'll be looking for. Went to Yamaha and the guy there said he dropped his gearbox into this tank full of small bb's that vibrates all day and night. He reckons it's made the world of difference to the gearbox on his TZ250. Expensive though. I've placed an order for a Zeeltronic ignition system Doubt I'll fit it to the DTR engine. But it's intention is for the TZR motor. It will come with a Powervalve controller too! Cheers for your input guys. Was beginning to think it wasn't getting viewed lmao! And about braveness, not really. It's a spare engine. If I really struggle that much. I'll take the box of bits to Yamaha and have them rebuild it. But it's actually surprisingly simple inside. A few cogs and bearings. Nothing major.

Just an update Engines split. Just needs cleaning. Spraying and rebuilding. Should be a few weeks yet. Will then need to figure out what I intend to do about the top end.#

Haha, will look forward to seeing more!

Hello, Those kickstart mechanisms are very similar to the kickstarts found on the Later 1989-2004 kickstarts.

They're wicked. It annoys me when some nobody tags over the top of them lol. Yeah, it's taking every penny of mine to build though lol. Let alone time. Need to get my final part of my bike license done and looking to do a dual rad setup.

Will try and get more done on the run up to christmas. Hopefully will have more spare time. Not so much on the money side of things done. Luckily not much needs buying now. All the bearings bought just need the crank rebuilt.
