Description
The DYNOJET Jet Kit for your YFM660 Grizzly gives you direct control over your fuel mapping across the entire RPM range, letting you optimize performance whether you’re running stock components or a heavily modified setup. With multiple stages to match your build—from a modest 5% bump on stock configuration up to 15% on a race-tuned engine—you’ll unlock both measurable horsepower gains and improved throttle response. Best of all, it’s a fully adjustable solution that adapts as your build evolves, so you’re not locked into one configuration.
