I have an 03 xr100 that is street leagal here in California. I need more top speed... BBR 120 kit looks nice. I was also going to add a XL185s 26mm carb also and keep the stock pipe. I also wanted to raise the gearing to offset the performance gain to achieve more top speed.. trips to the camp store!! Also... how will the stock carb work with revised jetting and what jetting should I do? I already have the frame cradle. Thank you all for your help!!!!
