"The Squeaky Bean" Yamaha Jog 1/8 Mile Sprinter by Areomyst

Postby Areomyst » Tue Mar 22, 2016 8:22 am

Hi guys!

It's been a while since I shared a project, and I've got several to show. I decided that I should show you my Yamaha Jog first. I got this from Daniel O. several years back. It's been a slow ongoing project. I originally bought it to tune and use in the NASRA scooter races, but NASRA has since "closed up shop" and I don't think there will be any more races sanctioned by NASRA. I still intend to take it to local track days and perhaps organize an event some day when I get it finished up.

The attached photos show what the scooter looked like when I got it. Pretty much stock... Because it is going to be a drag racing scooter, I wanted to lower the bike and move the engine back some. Daniel was kind enough to help fab up new engine mounts and do the welding for the stretch.

An additional note: Many of the parts I am using on this build are used. I've been very fortunate to find a lot of good parts over the years for nice prices. I don't think I'd be able to put together a build like this if I had to buy it all new! I have to extend a special thanks to Daniel O for giving me a really sweet deal on the Jog, and to RJ Whittman for hooking me up with his old plethora of Stage 6 racing parts!

The setup:
Stage 6 MKII Racing, air cooled
Stage 6 HPC crankshaft
Malossi VL14 reeds
ROOST inlet manifold
Keihin PWK 33mm Carburetor
UNI filter

HPI inner rotor ignition
Ignitech Sparker programmable CDI

Stage 6 R/T over range vario
Polini Evo 3 ceramic drive face
Malossi drive belt
Polini Evo 3 torque drive
Stage 6 Torque Control Clutch
Stage 6 clutch bell

I've got both primary and secondary gears for the gearbox... I will have to go double check the specs on those... For now, I only have the secondaries installed until I see how the performance on the track goes!

Here are a few photos of the engine work:

The porting in the above photos is fairly conservative. Later on, I thought I might switch to the Kiesler manifold that used the Piaggio reed cage, and I had to take the engine back apart to port the cases again so the reeds would fit. In the very last photo in the previous post you can see that there's a lot more material removed in the reed cage area. In the end, I selected the VL14 due to the suggestion of Marko at Roost Exhausts. I still have the Kiesler, and may save it for a 50cc Minarelli build in the future...

Attached you'll find a photo of the Kiesler intake. I think it's pretty neat. There's also a photo of the Roost intake, my adjustable strut, and the handlebars... The handlebars came off of my old 1982 Honda MB5. I flipped them upside down, and they worked pretty well on the sprinter!

I still didn't finish getting this together as I lost a bit of steam when I realized that I wasn't going to be racing in the NASRA races anymore, but I still have every intention of getting this thing on the track. Focus has shifted a little bit for now as I am re-purposing my Super 9 for use at the kart track. Here's how "The Squeaky Bean" is sitting at the moment!

Ciao,

NASRA gone? That's going to put a damper on scoot racing. I was wondering why I hadn't heard anything about the races. Last I contacted Jeremy was last summer - never heard back from him.

So this build was supposed to run in a 70cc class? Looks like a fun project :D
How many scoots is too many?

Yeah, they some some kind of issues with Brown County Dragway. My understanding is that it got pretty silly/nasty and after a lawsuit it was more or less the "nail in the coffin" for NASRA. I believe poor turnout to a couple of races also had an effect on the future of NASRA. If Jeremy decides to reboot it though, I'll be onboard as much as I can be!

Who knows, maybe someday we can host a scooterinvasion.net sprint cup or something like that! :)

Thanks for checking in Dan! Cheers!

Yes, it was going to be for 70cc class. I think that with the setup I had, I would've had good chances of bringing home a trophy! That's okay, I'm still going to get it finished and race it. :D
