Default CR80 reed identification help please

     

Can someone help identify these reeds? Manual shows a reed stopper, but I don't see one here. 1998 CR80, so who knows what hands have been in here before we got it last year.

I can see daylight between the reeds and their seat, so I'm assuming that is not good.

This is a trail / field bike for my 120lb kid, so if anyone has a suggestion as to what to get, I'm all ears.

thanks, I'll try to attach pic:

edit... OK, I can't until I have 5 posts I guess.

Can you just turn the reeds over?

Thanks, Are the reeds carbon fiber material from factory? And yes, I think I can flip them over... that is acceptable?

---------- Post added at 04:22 PM ---------- Previous post was at 04:15 PM ----------

I was chasing a high idle, weak bottom end power. Top end not terrible. It's been a long while since I was on one to judge tho.

I pressured up the crankcase, it held 6 PSI for 10 minutes,,, compression is 140 after ten kicks.

Found issues in the carb, like the air screw was fully seated, and missing the spring for it. The float height was .860 while spec is .750.

The jetting is 110 - pilot is 45, clip is in second groove from the (top) blunt end. We are 3500, but density altitude is often 5000 feet.

I can see daylight slightly on the reeds, so I am thinking of flipping the reeds (if that is acceptable), I made the float and air mixture screw changes (now 1.5 T out to start)... but the reed gasket ripped when taking it off, so I need to get one of those.

Any other thoughts?

Your compression is on the low side of usable.
