Athena 170
-
Can only say what I found, bought "restored " Dt250mx circa 1976 running on premix. Keen as ever to have as original as possible reconnected all parts to oil pump and bled system. No, it did not work at all, persevered without success so took off machine and checked drive gear was all intact (you never know) and all ok, just did not pump oil. No idea how long it had been disconnected or why, had it rebuilt for a measly cost and came back like new working. Did get some pics given to me at purchase showing condition prior to resto so will try and post some shortly to show condition. Don't discount the obvious because you have never seen it.
-
As said, I've got no reason to lie about it, my Belgarda pump was foobar'd and I'm not an idiot lol. I even took it into Yamaha Skellerns Cheltenham, where Rob told me the pump was not serviceable.
Why would they turn down work? I can only go on my experience. To be honest with you, I could show you photos of the engine, and having dirt being drawn into the pump could have been highly likely.
I mean that was the state of the head, the gasket was on upside down and it was still obviously ridden. So yeah, having a poorly maintained engine would be a good cause for suspecting the pump could fail.
-
Anyway, let's get back to the topic. My pump is working like a charm, and with some transparent oil lines I feel a lot more confident with it. But I mean this is the life of owning a two stroke isn't it? You can't be sure it won't break, fuss about or even start in the morning. I'll make sure the mixture is spot on and gradually move towards using only the autolube. Then we'll see if it breaks or not.
-
@irongamer727 The DT is a rugged motor, you'll be hard pressed for it to break if you look after it. Always use decent oils and just keep an eye on the gauge mate and you'll be fine.
Aprilia on the other hand...they are temperamental.

About 3km done on the dt170. Feels like a totally different bike. I'm still nervous as hell that something will fail but everything seems to work. Not bogging one bit, still quite cold outside ofc and I have not tried the upper revs.
Smoking beautifully and seems to be running rich (according to spark plug). Think I will keep this setup during the brake in. Soon time for another trip
-
@irongamer727 Leave it standard and Yamaha have done all the research to make it perfectly reliable.
-
@calum Yamaha? Are they involved in the making?
-
@irongamer727 No, you said two strokes are unreliable. They're not unreliable, they require more maintenance sure. But you've now modified something that Yamaha spent thousands designing and refining. You haven't spent thousands ensuring this will run reliably, thus you must except the potential for it to be unreliable.
-
Not sure if anyone is interested. Either way just finished my first 25km ride with the kit. Still feels really nice. However a break in isn't in any way fun. But it'll soon be over.
Here's a couple of pictures of her. Tell me if you can see them. New to this photobook thing.

Good for ya, cant wait to hear your thougts once you've flogged it a bit
Pictures is showing fine in the link
-
@jens-eskildsen I'll update this thread as I get more experience with it. How was the pictures? Blurry? HD?
-
@irongamer727 Create an imgur account, photobucket compresses your images.
Definitely look at getting a Zeeltronic for your bike. It will make such a difference with that 170 kit.
-
@calum I've already spent what I consider A LOT on this DT. Also have an NSR now. Ordered a stainless Romeu Henriques pipe for it. The DT is either way never going to be a performance machine. The Honda however..
-
@irongamer727 Yeah, and it'll be a shame not to make the most of it. A Zeel will allow you to unlike the full potential of that Athena.
Having done everythng under the sun for these DT's, Athena Big Bore, TZR RR Belgarda engine, the single one most thing I can recommend, is the ignition system.
-
@calum but it's expensive as sh*t! Still going to get beaten by my friends riding their gasgas, exc and so forth. Not worth it really. I just want a dependable everyday rider with a bit of oumph in it.
-
@irongamer727 It's cheaper than the Athena, allows you to increase the reliability of the engine and gives you much more power through the rev range.
You can even put a two mode map switch in so you can have it in economy or full chat mode lol.
