Nice video! I will try to offer advice in the order of items listed in your video...
I'd ditch those plastic guards, one good tree and you're going to get hurt.
Cycra guards work great and they are pretty light, Highwaydirtbike guards are nice too (See Kelly - Motosportz bike). Highwaydirtbikes Anti-vibration inserts.
I have double take mirrors, ask away, and flip out mirrors not legal in CA.
GPS mount needs to be a ram and ball mount.
We sell a front tire that is DOT legal, lasts a long time and is good on everything from sand/mud to hard slippery rock GT 216AA Fat Tire.
Stock exhaust is made by Farconni (not LeoVince), it's a good pipe but it is very restrictive and weights 12lbs!! Decat it if you are going to keep it. Remove O2 sensor, replace with 12 x 1.5 oil drain plug and ziplock baggy your sensor to save it.
Stock battery is 6lbs and will eventually fail on you in the form of poor hot starts,
Earthx 1.3lbs, double the amp hour and works well in cold. Battery tender works with Earthx, not with others.
We (ZipTyRacing) have an aluminum gas cap coming which we made with an updated sealing feature, better than Husky hard parts, coming soon. Stock plastic cap will eventually fail again.
Decat +
Map#3 will open your bike up to 82mph even with 14 tooth front sprocket. Fuel map switch is good. Map 3 will make your map 2 feel like a gutless wonder(and eliminate death from flame out accidents).
2.4 gallons is the stock tank, also see
Nomad tank from Motosportz or
IMS 3 gallon from Bill's add-on for the front.
Change rear turn signals to flush mount to the rear fender, stock ones are a headache when popped out.
Factory seat is a vinyl covered 2x4.
SeatConcepts replacement seat is very nice.
Stock skid plate rocks, a lot better than you might think. Removed my aluminum skid plate, put stock back on.
7602 Radiator Guards.
XF Racing coolant
Change your oil every 30, 100 and 300 miles initially on break in and then every 300 miles, Mobil1 0W40 Euro Formula. Highly recommend Stainless Steel oil filter.
