Looks awesome, I wonder if they would do any stroker work?

Everything I have read says not to go with a lighter flywheel. I suppose it depends on what you are doing but even a drag racer was posting slower times after installing a lighter flywheel.

yea they could do just about anything you want with a crankshaft, i think its about 3-400$ plus parts though. this crank costed me 400$ plus shipping. i sent them a used oem crank with a worn bearing. but this crank here should be the last one i will ever need lol.

ive been running a lightend flywheel for awhile now, it helps it rev up alot quicker and feels more snappy like a 450 when paired up with a fcr carb. to me it feels better when you pat the thottle alot on and off. depends on your riding style on wether or not you would like it.

Thats going to be a great build. I never did the lighter flywheel but would love to try one sometime.

i dont know why everybody puts down the idea of a lighter flywheel on these bikes. to me they got plenty of torque that it wouldnt hurt the bottom end too much. and depending on your ride style, it can work pretty good if you want a fast revving snappy motor.

Do you loose your lighting ability with the lighter flywheel? Seems like something changes or you have to do something when installing one, or is just bolt on and go no mods?

Well I have not tried it but from reading about others that have the lighter flywheel actually made the quad slower. And the one guy drag races so he wasn't just going by feel but his times actually got slower with the lighter flywheel. I have no idea if this always happens or it probably depends on how much weight they took off.

So just giving you a reason why some people may put the idea down - who wants to install a mod that could actually makes the quad slower? I could care less how fast it revs if that is not transferred to more torque, HP, or speed. I play race 450's up hills all the time and beat most of them on my 416 even though their quads rev much faster.

I notice they welded the crank, which keeps things together and true.

But I have always wondered why they don't stake them instead of welding?

what is it when they "stake" them? never heard of that?

Basically they use a pointy tool made of harder material than what is being worked with. They put the point in the crack or near the edge of it on one side or the other. Then a press or hammer is used to punch a good ding.

This prevents anything from coming apart by deformation basically.
