I KEEP STALLING. So I think there is something wrong with my clutch. Since I bought it I have hated the heavy clutch pull and the way it engages. If I am going too slow for a gear it will make a terrible noise like cracking. Clutch cable was recently lubed. The bike pulls a good amount when stopped in gear with clutch lever pulled in. I keep adjusting the cable but it's not helping. When I go slow it stalls an obnoxiously large amount of times. Any ideas on what the issue is?

It could be dis-engaging or not engaging all the way.

Have you looked at your clutch basket? It could be grooved and causing the plates to hang up. Not completely disengaging thus causing your stall. Check the clutch arm and push rod for wear also. Check the fingers on the basket and report back. The year of your bike and hrs on it would help.

The "terrible noise" is the rear chain slapping on the swing arm.  It's a normal result of lugging the bike.

 

If the bike pulls while in gear at a standstill, and is difficult to find neutral at an idle, the clutch is failing to release, or disengage completely.  The cause of that is usually the steel plates are no longer truly flat.  Notches in the clutch basket fingers and/or the clutch boss (hub) can make it worse, as can springs unevenly worn.

I did look at it a couple weeks ago. There are slight grooves but I don't think that is the problem, idk how to inspect the other components you listed

this is exactly what is happening I also can't find neutral a lot of times. What is the fix for this

Start with a new set of OEM clutch plates and a set of new springs.

Does it have to be OEM? There is a tusk clutch kit that is around 50$ and OEM is 200$ off motosport

The Tusk plate sets give generally worse results than OEM.  In most cases, it takes about 4 hours of run time to get them to disengage properly (the same problem you're fighting now), and the friction plates expand with heat so much that they require a lot of fiddling with cable adjustments on the fly.

Sounds like I won't be fixing my clutch for a while!

Are there any higher quality plates than OEM that you recommend

Some that claim to be, and in my experience are usually worth the money, are the Hinson plates.  Barnett, perhaps.  The original Yamaha plates are tough to beat.

I'm thinking I'll just save up a bit more and get the Hinson clutch kit with the basket too

You can file the grooves on the outer clutch basket, it's a temporary fix and the plates will slap back and forth harder than usual eventually breaking the fiber plates. I've gotten a half a race season out of my yz250 back in the day doing that, the 450 will probably not go as long, either way if the clutch and baskets need to be replaced anyway it should buy you some time. I agree with others stock Yamaha clutch is excellent, Hinson would be the only aftermarket on par with it.
