a yamaha y80 im building to run in a scrambler event

50 laps around a mostly dirt track with a mud section and some jumps, im signed up for the 3 speed underbone class so theres probably gonna be honda c70 suzuki fr80 and some other 3 speeds, still got a lot of work to do but its coming together pretty nice

(last 2 pics) it was slammed to the ground a while back and i used it as a daily for like 2 weeks until i realize it fucked my back up so i parked it ever since, its nice to turn it into something ridable again

got some frame braces done on the scrambler yamaha y80

theres a scrambler/enduro event coming up and im building this to run in the 3 speed underbone class, theres gonna be some 3 speed honda cubs like c70 and some suzuki fr80, 50 laps, gonna be hella fun

added a frame brace and swing arm brace because this thing have some rust holes, also flipped an aftermarket suzuki rc100 exhaust up side down and made it fit, all done by my local fabrication/exhaust shop, he did all this in 3 hours

Can I do some sort of relay on my 1981 C70 Passport? A possible back light as well for the instrument panel?

Got the new battery, like learning about the push start on it although it's a learning curve for sure. I don't get to use it enough to know it well enough yet.

With the new battery, I noticed the turn signals. There's a delay between when I flick it and when it actually turns on which I don't like but the main disappointment to find is that the turns signals don't actually blink. I can promise that's going to cause my death here. Is there some sort of relay I can do or something to make my turn signals blink? Do I need to just buy new ones?

Noticing a real problem with the big light turns off in the sky, seeing how fast I'm going. I don't need to give a cop a reason so I was curious if there's some recommended light people use to light up their instrument panel and speedometer? Maybe someone's done a little fix that's worked well?

Also whoever said I needed to tighten those two bolts in the steering column to tighten the slop I had before, it wasn't that. I found those bolts and they were down tight. There's still a lot of back and forth in the handlebars. The video showing it is from earlier in the day so the audio was from earlier me.

throwback to that time i decided to turn a yamaha y100 into a mx race bike

there was a class at this mx race thats for underbones, heard of it the day before the race so i decided to turn a bone stock yamaha y100 i had into whatever this is, did it all that night and went to the track the next day without any testing at all, managed to get a trophy simply because 3 other guys in my class broke lol

i used to ride enduro dirtbike about 6 years ago and left the hobby behind, i actually got another underbone race coming up at the end of this month but its for pre 90s 3 speed bikes so im building a yamaha y80, gonna be a lot of fun!
