flywheel weight to help with tall gearing( 08 yz450f)

My question is:

I went from the stock 13/49 on my 2008 yz450f to 14/47 to help in the faster sections in the desert. But, in tight technical riding and slow hills the bike is geared too high and tends to stall. Will a heavier flywheel help in these situations even with the tall gearing?

Yes, it will.

I have the same bike and run 14/46 in the desert. I added a FWW and it helped a ton in the tighter stuff with desert gearing. Although there is nothing that will rid the bike of stalling completely it certainly helped. Here is a link to my review of the GYTR FFW.

Thanks for the help! I read the review and everyone seems very happy with the GYT-R flywheel, looks like the one to buy.

I have the same bike as well, I use mine mostly for tight woods and tracks though. Im running 13/52 gearing with the heaviest gytr flywheel and lots of carb work. The thing that helped the most for stalling was the flywheel. With my setup i can let the clutch out in first and it will pull itself without even giving any throttle so i am very content with it. The other thing i did that made a huge difference was i added a boysen powerwing and cut out the screen on the air filter cage, that really opened up the bottom end and reduced stalling. Good luck!

Hows that chain gaurd handling the 52 rear sprocket? Is it gonna last or eat its way through it???

So far so good, i got about ten hours with this setup and there is no noticeable wear on the chain guide. However i did have to use a dremel tool to open up the chain guide so it would fit new o ring chain. I will buy a WR chain guide when it comes time to replace it because they have the o ring chain stock and it is the same bracket so it should fit nicely.

You should also look into the TM Designs chain guide. They last longer than either of the OEM parts.

Did I hear you say you took a dremel to the chain guide???? The chain will wear its own groove into the guide on the first ride.
