i see rick has cutting off up to 13 ozs on a fly wheel is that for all out race or trail riding or would that lose to much grunt climbing hills or in the mud,sand and does it realy help that much? would it help with my setup on the 400?

 

Yes it would help you quiet a bit.It will let the motor rev quicker.You can choose to either keep the electric start and he will only shave a little.Or lose the electric start and he will shave the max .With what you have done the benefit is worth it.

 

I had the 13oz removed off my trail mod setup so I could keep the electric start and it makes a big difference on throttle response and picking up the rpm. I'm with CED, definately worth it.

 

yes i would like to keep the lazy man starter so the wife can still drive it thanx

 

Alot of the kawa guys are lightening there clutch plates and removing the cooling fins on the backs of the clutches.

Try at your own risk. pic's of drilling on my pic page.

 

How are they doing that without rebalancing them, I don't think removing cooling fins would be a good idea either, they are there for a reason.

 

If your only drilling, you probably don't need balancing. removing fins you do.

You will have to balance if you mill fly wheel, right.

Cooler here in the north than in Oklahoma, we don't remove all the fins,

 

Yes you do have to rebalance the flywheels, but the weight your loosing in the aluminum would probably not even make a noticable difference.

 

ok, I can see this is going no where.

Your right the two pounds I've reduced my clutches is nothing compared to the 13 Oz. your talking about.

I've raced snowsleds and pulled ATV's, (Polaris), all my life, the very first improvements made was clutch lightening, if you don't want to do it, that's fine. It was just a suggestion, a lesser expense than fly wheel lighting, I though I'd pass on.

Have a good day.

 

I wasn't trying to start anything you guys jump to the gun when someone has questions about something you do. It may work, can you tell any difference in throttle response?
