  Hey all. I added the backdraft exhaust, velocity stacks and performance rebuild kit rejet to my bike and I fired it up at 2.25 turns out both sides and it will run well for about 10 seconds and then slowly die. I smell a lot of gas and exhibits running rich condition when you rev it. After a good mid rpm rev it will bog down and die. Any idea why this could be happening?

  @Zacharia Fouda further tuning is required. its not necessarily a plug and play situation, sound slike you may have a stuck float or some gunk in there keeping the floats open, if the bike ran fine before then this is what we call installer error, somethng was missed during install or just some crap from the tank got into the carb. if you dont have a fuel filter, def get one on there. also check that all spark plugs are gapped and firing properly. make sure the slides are functionign and that you didnt accidentally lose the needdle jet. if this is your first time doing this, its pretty easy to make a mistake and not uncommon!  😎 i have a 4 part video series on youtube that will really help you get familiar with the carbs! https://youtu.be/gYLGWX_y_v8?si=wOX8UPJZ9PpYnzyk

  and heres a tuning ghuide that will help you properly tune that bike up!

  @Zacharia Fouda also, the tuning kit comes with multiple jet sizes, so you may just be too rich, start with pilot circuit first, then once the bike idles good and stays on, move to the main circuit, again that tuning guide is reeeeeally going to help you .
