Jetting Yamaha YZ 2T Moto

I’ve been using this app for my Yamaha’s for probably five years now I love it ! I’m constantly sending it to my friends and they’re always asking me how my bikes run so crispy! I highly recommend this !

I’ve been riding & racing motorcycles for almost 50 years. This takes all the guess work out of jetting my YZ250 2-Smoker. I actually thought I was pretty good at setting up my bike. This made it even better. What I like most is being able to use a specific location (as in going to a new place to ride, with different elevation, weather, humidity, etc). I didn’t leave this review until I’ve used this for 4 different riding locations, and changed jetting slightly for 3 of them. Made a significant jetting change for one of the locations, but what they all had in common, bike ripped. Clean jetting, no pipe drool, super crisp! Thankfully I have tons of mains and pilot jets. 3 different heat ranges on spark plugs and several carb needles. If you have what’s needed, your bike will run perfect!

Would like to see more data and support. For instance im using an older engine, but with keihin pwk. But I have to choose a 2002. And doesnt pwk make more than one mm size? Will this app continue to get updates and data entries? Im also running a br8eg, but It auto fills in a ngk br10eg. I would have loved to give this 3 stars, but at this point im saving most people from spending the money cause I havent seen or heard of any further updates. Seems un-completed and leaves a lot to desire.
