Blaster cr80 flat tracker

[undergroundart]

grab bar showed up but didn't fit. had to cut 1/4 inch off of each side so it would slide in place. kinda annoying. taking it easy today and just gonna make a rear mount for the number plate. I have a vinyl cutter (makes basic stickers) and my boy has been working on different number fonts and colors. he s pretty excited to put them on.

Got the +2 a arms and front hydro brakes on today. this thing is looking pretty fast sitting there. low and wide. I need some advice on getting one of the ball joints tight. no matter what I tried the whole thing would just spin. does anyone have a trick for it?

 

[harley1-5]

I allways try to put them under a load to prevent them from spinning when that happens

 

[undergroundart]

I had kinda thought of that. I put a lil pressure on it. maybe ill try a ratchet strap and squeeze everything together.

Sometimes a quick hit with an impact gun gets it snug enough to torque. Try using a fork to put pressure on it too.

got a million little things to do, but she s getting real close. I bought some yfz 700 heel guards to put on also. just have to fab up a mount. safety first. early last year my foot got sucked in between the nerf and rear tire. only broke a small bone, but that thing hurt bad and for a long time

looking awesome

finaly got the kart tires mounted. turns out it cant be done without a tire bander. she s offfically a roller now. once I get a chain I think it d be driveable also. since my work schedual doesn't really leave me much free time right now I think the next step is to send the swing arm out to be shortend a couple of inches and have a sway bar made.

 

[harley1-5]

that thing looks mean

 

[undergroundart]

should be fast too. the engine is supposed to have like 19 horse stock.

nice work so far !
tell the boy he did good on the number plate.

whats your reasoning for shortening the swinger ?

 

[undergroundart]

traction. get your butt more on top of the axle and it grabs a lil better,

 

[Blaaster]

I can see no good reason in shortening the swing arm, surely shifting weight is an ample solution!

 

[jus_me]

for a small rider I could see doing this especially with a smaller engine. How big is the rider?

 

[undergroundart]

he s pretty little. maybe 50lbs. shortening the swing arm is pretty typical for flat tracking.

 

[harley1-5]

hope he likes it

This is sweet! I love all the fabbing work, keep us posted!

got dual radiators off an old dirt bike today. I think these are gonna work way better than the stock small one. problem is just finding time to work on it.
