has anyone welded before on any of the yamaha flyweights? how do the weights take to welding? are the weights made of powedered metal, or are they forged? i got some weights and would like to fill in the engagement notch that was put in by previous owner. i can weld and regrind them to be like stock, as i'm capable of that task, but i don't want to start welding, only to find out the weld goes porous or something. kinda like if you were to try and weld cast aluminum.....what a disaster. any thoughts or experiences anyone?
 
I have tig welded on weights before with no problems,they seem to be good metal. After all they do take a lot of abuse in the clutch.
 
Are they tempered? I am not sure if the weld will last as long as the original metal?? Just a thought
 
I'd be afraid of weakining the weight and having it break it the weld, thus throwing the whole end of the weight flying

I agree and after all the time you will have in them, isn't just easier and cheaper than your labor to go buy new ones and have the piece of mind they wont break on the trail....JMO

They can be welded,old sledders trick was to put a bead of weld in a certain spot to fine tune the weight.
 
HI There i'd be carefull in trying too weld those weight's.they are a tempard steel.the heat from the weld may cause cracking your spliting.you whould hate too see your primary explode because of this.IS it werth it.But if you deside too do this i'd try this on a old weight.Do not cool it off in water.
 
im not too sure about yamaha's metal but when i had my race sled with benders wieghts in it that allen ulmer built those wieghts were welded to a percise measurment that i had to match when i had to replace them.it took the welds fine & ran perfect i must say..i wouldnt ever hesitate to weld some beads on a wieght to fine tune after that sled.just my experience & 3 cents on the subject
 
Yes you can weld them and regrind no problem! Just don't quench the piece after welding to cool it, just let it cool slowly @ room temp.
 
weld will be softer (wear more) than the original weight steel will. works to a point.. then will dish out.. this is on profile, roller surface contact..

i'm looking to fill in the engagement notch, where the roller would contact. i want to have the same original engagement flat, that yamaha puts on the 8bu-00's. these have a high engagement notch right now. if the weld is softer, and the rollers will want to abuse that area a little bit, maybe it won't hurt, cause its not on the arc surface, just the engagement surface? the sled is only there for a very short period of time.

...these are modified 8BU-00 that i'm asking about.
