MOTO2N News for June 2019 – MOTO2N | Denver

Still extremely busy. So busy I don’t have time to return calls UNLESS you BOOK ONLINE!!!

If you absolutely have to call, let’s say the online booking tool isn’t working for you, then the best times to do it are between 8AM and 9AM Tuesday thru Saturday. I’m likely to be doing computer work in the mornings at those times, and I’ll have my phone next to me. I’ll do my best to take your call.

Leave a message if I don’t pick up. I will do my very best to return your call within 72 hours. No guarantees on that, by the way. The *BEST* way to get me is via email. The address is moto2n.colorado@gmail.com.

I have no idea when I’ll be able to make it to the Springs again. 1000x apologies to people in the Springs, but Denver’s keeping me extremely busy. I don’t have time to spend my weekends/days off in the Springs like I used to do. I end up doing “homework” on my days off up here in Denver.

BOOK ONLINE if you’re in Denver. If you’re in the Springs, send me an email. If you can’t get the online booking tool to work, send me an email. The email address is moto2n.colorado@gmail.com.

Alright, now for the fun stuff.

Yamaha C3 Fuel Pump Replacement

Fuel pumps for EFI bikes are expensive, and, if you let your bike sit for a long period of time, there’s a good chance your fuel pump will break. I knocked this one out in about 2 hours around the corner from my customer’s apartment in downtown Denver.

The Yamaha C3 is a cool bike. It boogies pretty good for a 4-stroke 50cc scooter. I wouldn’t mind having one. Bet a case of beer would fit in the trunk if you unboxed it!!

Antique GSXR Track Day

I took 4 days off for my birthday, so I went and had some fun on my antique GSXR750 at High Plains Raceway.

It was easily the oldest bike at the track by a good 15+ years. I bought this bike 3 years ago. It didn’t have a fuel tank or any bodywork.

I bought a used tank and bodywork. Also installed a Dynojet Stage 3 jet kit. It has Airtech fairings, a Yoshimura duplex exhaust, Calfab overbraced swingarm, powdercoated wheels, custom throttle cable, new chain, new tires (Bridgestone RS10s), new Zero Gravity windscreen in translucent blue, gutted FZR1000 gauge cluster, custom made (poorly) fairing stays, Pingel petcock, Bandit 1200 front master cylinder, new grips (vintage Honda shit, hilarious), alternator delete from APE Racing, custom wiring harness, new EBC brake pads front and rear, K&N pod filters, new wheel bearings, etc etc too much to list.

At any rate, it is a FANTASTIC track bike. It performed extremely well at the track. I was damn near bouncing off of the rev limiter in 6th gear at the end of the 1/2 mile straight at HPR, which is damned close to 150mph going into T4. This is the fastest bike I’ve ever had on track. Prior to this, I raced a Honda RS125 and tracked an Aprilia RS125. The Honda made maybe 35hp. The Aprilia, 22hp on a good day. This bike? 90hp or more here at altitude. It weighs all of 390lbs, which is damned light for a sportbike of any vintage.

The chassis on these old slingshot GSXRs is nigh but incredible. I couldn’t upset it. I tried. No speed wobbles. No weirdness. Just point-and-shoot.

I kept going faster and faster as the day progressed. I started out slowly and pitted every 3 laps to check the bike out. My exhaust fell off during my second session. I pulled into the pits and fixed it. It runs a total-loss ignition system, but the battery lasted for the entire day. I chalk that up to the custom wiring harness I made for it. The only thing that draws power is the CDI box, and apparently it doesn’t need much power at all to keep going and going and going.

This bike represents 3 years of labor, many thousands of dollars in parts. It’s been a long time coming, but I finally got to twist its throttle in anger at a track day. Blood, sweat, and tears paid off. 100% worth all of the time and effort I’ve put into it.

This is what sticky tires look like when you get them hot:

People always ask me what year it is, and I don’t know how to answer. The frame’s an ’89. The subframe is from a ’91. The wheels are ’91. The engine is god-only-knows, but it’s from a Katana 750. It pulls hard and revs to 13k, so I suspect it has the GSXR cams in it. I don’t know. All I know is I built it from parts, and it’s FAST and very fun to ride. I just say it’s an ’88-’92 “bitsa” GSXR750. A bit of this, a bit of that… eventually you have a bike you can ride. 3+ years, thousands of dollars, and 100+ hours went into this bike. Was it worth it? ABSOLUTELY!!!

Wanna buy it? I’ll do $3,500 on it if you really want it. Not a penny less.

Crank Replacement on a Yamaha Zuma

I’m more than willing to split the cases on your scooter… assuming you can afford to pay me to do it. LOL.

High-zoot rebuild on a Yamaha Zuma. We’re doing the Polini 4-Race crank w/ a Polini Contessa kit. Stock carb. Leo Vince exhaust. This thing’s gonna haul some ass!!!

I’ll be disappointed if it doesn’t pop wheelies.

I’m going to end up building this engine on my coffee table, which should be a whole heap of fun. Wish me luck!!
