Aluminum Flywheel 10krpm

Have only used for a short time as I am waiting for a jetting kit for the carb i am running, but holds up well and the valve springs don't want to let the valves float even when free reving the motor, for the cost of this kit I would reccomend it to anyone on a smaller budget wanting to get more performance out of there mini bike or go kart engine. This went in a coleman b200r but will work for most honda clone engines. Don't recomend to use the spark plug that came with the kit, go buy an ngk bpr7es, its the equivalent of the included spark plug but will run better

Great fit works I recommend this

Used this flywheel on a predator build. I didn't want to fork out for a billet flywheel on a budget-built engine. This flywheel is rated for way more RPM's than I will turn. There was a noticeable difference in felt torque after install. I assume due to the weight difference between the cast steel flywheel and the aluminum one. This is cheap insurance against a grenading cast iron flywheel that could seriously maim you. If you have any performance upgrades that increase the RPM's, I highly recommend this upgrade. Be aware, if you run any type of lights, this flywheel will not provide power.

This is pretty awesome and is a must have if running with out a governor. Very easy to install and don’t forget to lap it to the shaft prior to installing. With this being lighter than the stock flywheel can tell it has a little more torque off the line. I’m buying another one for a project I’m working on for a customer.

This fly wheel is actually really good, heavy and nice can’t wait to install it and let her spin, if any fly wheel should be bought, please choose this one

So far, seems to be working well. Haven't installed the valve springs as I can't find my feeler gauge. The casting has several spots that appear cracked, but I think it's just casting blemishes rather than actual cracks. There's not much of a weight difference from the cast iron one but wanted to get rid of the plastic fin wheel and not spend over $100 on a billet.

(Predator 224 non Hemi) Flywheel does not sit close enough to the engine so the blower fins rub on the recoil cover and the magnets for the magneto only overlap the magneto by about 50%. That may explain why some have complained of weak spark. I have already installed the springs and lapted the flywheel extensively to try to make it fit. Not even going to try to get refund.

Overall construction seems solid, been running it on my Go-Kart for a week now. With that being said let's move onto the negative. The center bore size was terribly off (I measured a whole 1mm off with digital calipers) and had a massive lip on the inner side, I had to hone the bore with a set of files and a Dremel. Overall if you have the tools to file down and hone the bore so it sits on the crank properly it is probably worth the money.
