Cam Replacement, Good Buy?

[Silver7]

Hey guys,

I have a 2001 YZ 250F that is hard to start . A lot of people are saying to replace the cam with a newer one from 2003 and up. I am thinking about doing this, but need a little help. I have included a link to an ebay listing that I think will do the job. What do you guys think? I asked the seller what year they are from and he indicated that it came out of a 2004.

This is the link: YZ 250F Hot Cams

Thanks!

Shouldn't be an issue at all.

Those will work just fine. While your in there, you may want to replace the cam chain as well.

You will also want to pull the decompression cable and arm and replace it with this plug http://shop.thumpertalk.com/Decompression_Plug_p/qmr-03dpb.htm . I have done two bikes now and they work great.

They should bolt right in. Make sure you check the valve clearance and shim if needed. Not sure if I would waste my money on used cams though....look into some new ones. I know www.motosport.com carries hotcams. Just a suggestion.

These should make my ride easier to start right?

I have an exhaust cam from my '03 WR250F that i would make you a sweet deal on. It probably has less than 15 total hours on it. PM me if interested

You might want to find out if those are the phase 1 or phase 2 cams. Keep in mind that your power band will be affected and you will loose some top end if they are the phase 1. Check www.hotcams.inc for dyno charts. Ask for the part numbers from the seller and if the intake has been degreed to move the powerband. I wouldn't buy them if the seller doesn't know what they are. You can also purchase just the exhaust cam with the decompression feature new from hotcams.

I put a new exhaust cam in my 01 YZ, wasn't a hard job at all... I would also reccomend changing the cam chain while your in there. It will definately make your YZ about 6000x easier to start

What exactly is the diefference in the 03 and 01 cam?

Why pull out the decomp lever and pay $20-$30 for a plug when you can leave it in and make un-flooding (scientific i know!) and therefore restarting your engine a snap when you have a stack and dont pick up your bike immediately, or is it the weight saving
