Sweet YZ!!! Glad and sad that you are into updating these old 2t's, it's just to bad Yamaha doesn't have the nuts to do it. I have a Lonestar outlaw efi banshee that runs amazing. I also am going to start on a kx500. Torn between doing FI or the APT for it.

DONE!!!! With the first few test session behind us the bike is working better than expected.

APT SmartCarb works awesome so far and we are heading onto the Dyno next week for data.

More info to follow within the next couple of weeks.



Well, your almost done, go check out one of these....http://www.eddie-sanders-racing.com/category_s/126.htm

I am really interested in hearing about the results from the APT carb vs the stocker. There are some treads on KTM and GasGas forums about it making a big difference.

the APT is the real deal, but it isn't exactly cheap. Lectron has updated their line of metering rod carbs and are getting great results as well. My buds are telling me same performance as APT at half the cost.

APT is taking orders for cast body carbs. Half the price of the billet body.

Dyno Run Update

We have been testing the bike on the track the last couple of weeks and were noticing that the main difference between the stock carb and ATP SmartCarb was that we could keep the bike in gear longer.We felt that it would still pull hard when we would had to shift with the stock setup. Even though the stock carb comes on quicker we had absolutely no problem pulling out of the corners with a smooth power delivery which made it more like a 4-stroke type power but then pulled very strong up close to the 9K rpm range . Also we have noticed that we are using less fuel with the SmartCarb over stock. We haven't measured exact values as of yet but will in the next few test sessions.

The below Dyno run confirms what we felt.

PLEASE NOT THAT THIS DYNO RUN WAS NOT DONE TO SHOW HOW MUCH PEAK HP OR TORQUE THE ENGINE PRODUCES BUT RATHER THE PURE DIFFERENCE BETWEEN A PROPERLY TUNED STOCK AND ATP SMARTCARB BACK TO BACK WITH THE SAME BIKE SETUP.

Blue = 38mm SmartCarb
Red = Stock 38mm PWK



Thank you to Crower Performance for conducting the test for us.

In the next few weeks we will do more track testing to fine tune the suspension and have a few pro level as well as intermediate level riders give some feedback on the entire bike.

So far we have been very pleased with the bike and it is time to let independent guys and magazines test it for additional feedback.

We are planning on running the bike in a few selected races like the 2-Stroke Nationals and so on.

How in the living hell did I miss this thread? That bike is Beautiful man! I think those YZ's look so much better as a 2 stroke than a 4 stroke. Definitely going to do some reading up on this build.

Awesome bike!

simply awesome looking bike, but in the pics the bike appears to be a prop for the model as opposed to the bike being the feature..

OCD alert!!!!! OCD alert!!!! thats a sweet bike, no doubt, and I hate to bag on it. But i have to. What the hell is with that countershaft nut and lock washer? At very least you could have taken some scotch brite to it and wiped er down with some 3n1 before the big "photo shoot". Wink

damn nice bike though!
