Preping a YSR

Is a steering stab required on the mini's?
front pads wired?
I'll wire the drain and fill.
the bike's set up for premix, all of the oil injection stuff is gone.
The kill switch works.
all lights are gone with the aftermarket bodywork.

what else am I missing?

 

When I was racing 50's I didn't see anyone with a steering stabilizer. Doesn't mean it wont help, but i never felt it was necessary riding one.

As for prepping the bike, check the rules with what ever org you are going to race with. They very slightly from group to group.

Also the YSRs don't have the most reliable engine. Definitely don't use it for any endurance races. We tried to use one for a 24hr race, and went through two cranks before we threw in the towel. I just don't think they were designed for hard use. Find a NSR50 or XR100 motor to throw in it, if you can. But also check with the org you are riding with to make sure its allowed.

 

thanks!
The goal is WERA kids class. I don't think they do enduro's.

 

An XR is an easy swap. I have done it. Plus the 4 stoke is easier to ride. Get a fork brace and a second fork spring. Also, if you can replace the swingarm bushings with solid bronze ones.

 

It has a second spring and a Fox shock already.
We'll swap when he kills the 50. For now I just want him to have fun and get comfortable at speed.

I'm mostly worried about what I'm forgetting that WERA is going to require. I don't want to get sent home at our first race.

 

You deffinently want a fork brace too. Mine would want to dart all over the place when I got on the brakes hard before I got one.

 

thanks!

 

is there any other options besides a used Calamari? With me on it it's down right scary. I can't tell yet with him.

 

I wouldn't spend a penny I didn't have to on a YSR. It won't be competitive anywhere. Do the bare minimum to safely get your kid on the track. If he likes it, spend $1000-$1500 on an NSR or a two stroke mini motard.

 

well, it fits him pretty well right now, we have it already, and he's never driven in anger before. It seemed like a good starting point. He's begging for a Grom, but that ain't gonna happen.

 

Didn't mean to sound negative. We did the whole mini thing, and I hate to see a race dad set off on the wrong foot. By all means let him get his feet wet on the YSR. If he likes it, get him something competitive before he gets discouraged.

 

No discouragement taken. He likes it, that's the first step to getting him hooked!
Besides, the way he's growing I'll be looking for a Ninjette next fall :lol:

 

I have a Daytona fork brace, but it came with the bike. I know I found another company by searching YSR race parts or something like that. I would seriously consider a Kayo if I was looking for a new bike. Even over an NSR. But I am a 4 stroke guy.

 

the Kayo seems to be a modern interpretation of the YSR.

Thanks for the pointers. I'll look around but might end up just fabing something to work for now.

 

The Kayo is kinda a mix of YSR and NSR. We have 3 or 4 in our club now. I am interested to see how they do next year.

cool! I didn't find them

 

So, how is the YSR going?

 

new shoes
body work
fixed the exhaust leak

still need to wire it and find a fork brace.
Seems to run pretty good in parking lot testing.
