Yamaha rivet weights

[schmeg]

I just got some steel rivets to add tip weight to the stock weights and can't figure out how heavy they are.
One set are 13.9mm Part#90261-06034-00
the other set is 10.3mm Part#90261-06015-00

I just want to add 2 grams to the tips to pull down the peak RPM from 11000 to 10,800 or so. I looks like I may have to find a beam scale to weigh them. Thanks for any help.

From manual 90261-06034 is 3.6g 90261-06015 is 2.4g

if you have a digital gram scale, that will give you an accurate reading

the stock weights are loaded with 3 of the 4.5 gram rivets already,only way to add tip weight is to add washers to the rivets or make some lead rivets,i added 2 grams to each end rivet by making some 6.5 gram rivets out of lead and it didnt change my rpm on top any at all and im running a softer front spring as it is,still turning 10500-10700,the stock weight profile is too flat i guess so it doesnt show minor adjustments like that

Thanks for the help. Sounds like I'm chasing my tail with the stock weights.
