Goofit Big Bore Kit works with this crankshaft perfect no problems big different results a lot more power.. I'm 264 lb this got me up to 45 46 miles per hour little too fast for me but a big different well worth the money the time very good product from this company...🤗
Works awesome for what I needed it for just needed the tools to put it in there took me about 30 minutes to an hour to have parts completely swapped over and out the engine back together
Awesome crankshaft that makes a difference worth the money,labor and time investing.
The product specifications were perfect for what I wanted. This was just the crankshaft that the mini ATV needed. The old one wasn't working all that well, and after I fitted this, it started running smoothly-just like the day I bought it. Delivery was also perfect, in fact it arrived a couple of days earlier than what was stated in the order. I had been to many auto stores in the past looking for this, but never found the right size. It was a surprise of sorts when I found the perfect match.I have been using this for the past six months now and am totally satisfied with it. The price is also optimum for the product. In fact I thought I would need to spend more to get this, but was surprised at the price quoted. My son feels the ATV races faster these days with this crankshaft, even faster than when it was initially bought. Just perfect for what we needed, thanks to the seller who thought about this.
The description was spot on and so is the fit.. perfect! It arrived faster than we expected. So glad someone is selling this; saved us the hassle of looking. My partner was going nuts looking for the right one and it was a good thing the crankshaft was described right which was why we opted to order it. Quality of the product seems really good and we didn't need to do any modifications anymore because of the right fit. The price is just in the right range, we were expecting it to be just so. Finally, my partner is not so cranky anymore because we found the right crankshaft! Hahahaha!
