Okay rear both wheels, forks, and rear shock were replaced by previous owner and I think the rear bearing is going bad. Need help identifing the rim so I can order the correct rim. The stamping on the rim says 4JH R-86 on one part and 17XMT5.00 on another part. I believe the rims and all are from a yzf 600 or fzr1000??? But not sure, anyone know for a fact what bike, what year this is from?

I'm thinking that the bearing is bad because of an issue I traced and leaves this to be the problem I believe. Been squeaking for a few weeks, at first very slight and faint, now it sounds constant "squeek squeek sqheek squawk" faster and faster as I speed up. A few days ago it got worse and getting into first gear it clicked and chunked into gear as I took off, then in third gear as I tried to power around a car it felt like the clutch wasn't grabbing and slipped a bunch. Got a little bit of grinding and slowed down. Drove it normally home. The next day with some advice from someone on here I checked the cable and it was off a bit. Did some clutch cable adjustments and tightned up the chain, drove it today and no slipping but the squeal is still there. I rode it around without a helmed down the block slow in first gear and its coming from the rear tire for sure. The chain is in good shape, all o rings are intact and no rust. I keep it clean and waxed pretty good.

So, any ideas on my rear tire?
Or comments on my issue at all?
Thanks in advance.

Sure sounds like that's off a '94-95 4JH YZF600. The Yamaha p/n for the wheel bearings is 93306-20469-00; standard bearing size is 6204. The sprocket carrier bearing is 93306-20644-00; standard bearing size is 6206. These bearings are available at any bearing house for a lot less than a dealer will charge; I suggest you get the -2RS versions, with 2 rubber seals protecting the innards.

Awesome, Don!

Ya, sorry for the multiple posts, dealin with a shotty internet conenection.

Would it make sense to be the bearing considering it only makes noise when under pressure. IE: squeals when on the throttle, but no noise when I pull the clutch?

Before you start buying parts and hammering things apart, pull your sprocket cover and draw out the clutch push rod. I would be very interested to see what condition that thing is in ...

Rod looks good, what and where on the push rod would show signs of ware and what would it look like. Last I pulled it out it looked good to the naked eye but I wasn't inspecting it for damage.

You want to look at the innermost tip, where it rides against the ball. Look for any mushrooming, heat bluing, or other indication of unhappy metal.

Gotta put the kids to bed, then ill go pill it out and post a pic with my findings.

here it is.

What do you think

Also, you said 94-95 YZF. i looked on allballsracing.com and they're description was Yamaha YZF600 95-07. Will that work for me maby? Heres the site page.
