Athena 170

@louis-james alright
-
@irongamer727 recommend getting a decent reed block on there. Many can be modified to fit
-
@louis-james naah at the moment I simply want her to run good, start easy and stay that way.

As I suspected my pilot jet to be too big (size 35) I ordered a smaller 25. But the bike literally ran like shit and the idle was very uncontrolled and the bike just sounded wrong!
Is the next step to order a larger?
I can without a drop in rpm turn the airscrew all the way in, no change really.That must be an indicator that it's to small right?
-
Yeb sounds like you need to up the idlejet in size.
-
@Calum agree?

I'm now contacting Adrenalin (the company I bought the kit from) and I'm asking for a refund.
The issue is that the casting is shite, there is a microscopic hole on the cylinder that leaks coolant, and that the powervalve housing is too big so the bush cannot seal properly.
Exhaust gases and oil pours out if the pv, bruh.
I have more or less demanded a refund, but I don't think they will give me that until Athena in Italy have examined it..In theory I won't have the Dt running for over a month, unless I immediately mount another cylinder I had from a spare engine..
That means all my jets have been bought in vain and all that, great.
The lesson here is: Do not buy the stupid Athena big bore kit. Even if you don't get a really bad one the power gains are barely notable.
To really benefit from it a lot more have to be done.Sometimes life isn't easy..

@irongamer727 I'm sorry to hear that bud, been there, done that, got the T-Shirt.
To be fair, I didn't have half of the issues you have and at the time (being 17) I thought the gains were decent.
But having been on an Aprilia, and for you the Honda, you begin to realise that the Athena kit is still worse than a decent engine. The DT is a cracking bike for everyday use, but I wouldn't bother with much else. Zeeltronic gave the biggest improvement. Bigger carb, V-Force reed block is tempting and exhaust. That'll give your DT a really nice improvement in power, without compromising reliability. And then enjoy the 20 or so brake it gives you.

@irongamer727 I've had casting issues with polini and malossi too. Never good fun. Usually they still need case matching and porting work. Not too bad when you can get new, performance crank cases for like a hundred quid on the little peds. Horrible if you enjoy a bike other than a moped basically. Incidentally just ordered an Athena kit to take a good look myself.
-
What would you do?
Take a full refund and buy a forged piston to the original Cylinder and mount that or take another Athena cylinder?
The carb is already set up for the Athena but it's not much work to set it back to stock.
Could the bike be worth more with the Athena?
-
@irongamer727 I don't think so, if it were me in the market for a bike I'd rather buy stock or close to it and do the work myself.
Other people might feel differently but that's my 2p

@glynn123 I'm so done with the big bore kits
-
