Well, I know a little about these clutches. are you still having issues with them? And if so, what is happening to the wet clutch. and second, are you having any issues with the outer clutches at all? When you replaced the clutch, did you use an OEM clutch or an aftermarket one? Did you replace the one way bearing as well. and when you replaced the clutch, did you replace the outer clutch drum?

Matt

[johnney]

yes both clutches where oem  and I replace the one way bearing and the outer hub came with the new wet clutch

[strike250]

When you say you went through both clutches in just about 250 miles, I'm guess the replacement clutch was worn and possibly had wear marks on the clutch hub as well? did you do any work to the primary and secondary clutches at all?

[strike250]

The Yardsport YS400 is a mix of parts from the Yamaha parts bin. The manufacture is HiSUN, who also happens to manufacture parts for Yamaha and more OEM's. The bottom end is basicaly the same as the Yamaha 350 Grizzly/Bruin. The top end is more of less off of a Yamaha Kodiak 400, early 2002 style. I would start by using OEM Yamaha parts for the clutch. 2007-2011 Yamaha Grizzly 350 wet clutch. the parts are of higher quality than the Chinese counterparts. This might be part of your problem. They bolt right on and will work and last much better.

[johnney]

thank you , I will try that ,

[johnney]

My secondary clutch was junk, would a secondary clutch from a 350 grizzly fit 2007-2011

[strike250]

Yes, I'll provide the Yamaha part number later today.

bruin and grizzly are air cooled ys 400 is liquid cooled

[strike250]

Yes, but the parts internally are shared. Not all but most of them are the same.

can the bruin bottom end be changed to make it liquid my ys400 rod bearing went

The yamaha clutch only has 4 shoes while the clutch in my YS400 has 5.  Before I spend $200 are we sure it fits?
