X2 wiring diagram and walbro hp tuning adjustment

I've had an x2 sitting in the garage for over a year and now finally decided to fix it up. I did everything that I know as a neebie for more speed and horsepower. I installed a hp 15.5mm hp walbro carb, boost bottle, saucer air filter, fatty exhaust, even added weight to the cvt trans by cutting metal stock and placing one in every other spot along with the original rollers to keep it at a higher band for top speed. If anyone knows of anything else that i can do for more horse power, it would be greatly appreciated.

I also need a wiring diagram for the x2 because it seems that who ever had it before me messed with the wiring and i have no idea what he did. i got the left blinker to work but the right side isn't getting any power. I don't think it's the relay cause then the left side wouldn't work. I also think that my battery is dead from sitting for so long. It's been charging for almost a week and I'm only getting 9.6v out of it. Also when the key is on none of the lights work unless i have the charger hooked up or the bike is running. If anyone can help me or give me some ideas, it will be well appreciated. Thank you

theres more room for improvement...one thing for sure performance engines dont have e-starters or extra wiring thats not needed................

Adding weight to the variator plate will only suceed in losing the lowerend power because itll start variating the sheave and pulley way too early...to get performance and to customize them you need to either lighten the rollers a tad or get a GY6 roller weight kit............

You need to lighten the flywheel ,,add a rocket key,,mod and lighten the clutches,,lose the basegasket under the head and take a dfremel and powerport the intake/exhaust ports to make true power.............Good Luck

Thanks for your reply. what weight would you suggest to start out with cause I've heard and read so many different things about the cvt to get more power. I heard to remove the extra roller and place them in every other slot, then to also do that but add more weight and lighter weight like you said. what grams should I start of with to see where I'm at. They go by grams right? I think that's what I saw on one of the sites. thanks again

As long as the raised offset portion faces the exhaust port or the 11 o'clock position with the slot in the crank oriented at 12o'clock......

If sams building the heck out of it and he has to remove your flywheel maybe he could mod the stock one or maybe he has one on hand and will throw it in to save time or maybe he can leave the flywheel off so you can add the rocket key yourself....

Go to your nearest USPS and get a Medium size, if it fits it ships box, it's free and shipping will be around $11. If you put it in your box it will be 25 or $30. I ship all my engines that way.
