Building my first trackbike, the ongoing saga

Postby spotthedogg » Wed Jul 10, 2013 3:28 pm

Hey guys, want to start a build thread for my 1990 VTR250 race bike. I was blown away with how nice this is to ride, then I started tearing it apart. I have many parts that I will be selling since unwanted for the track, let me know if you need something like lights, tool kit etc

have you talked to Benz yet? maybe you guys can hook up at the track sometime.

I was going to mention the back brakes but with the scenery there I know you're thorough ;)

looking forward to updates

I'll have to keep an eye on this. I'm just getting around to getting the F2 track bike running, then have to do the engine rebuild on the track VTR project.

Can anyone tell me how to bypass the clutch and side stand interrupt switches? I have the left switchgear off and the side stand will need to come off for race season. I'll likely leave it on for now as it is permitted at track days.

All the left switch gear will unplug at the junction box at the triple tree - green 12 pin plug - except the two wires going to the horn, which unplug at the horn.

There's no sidestand switch - unless they did something on yours that isn't on any of mine. Bypassing the clutch switch is easy - just find the silicon rectifier (diode) inside of left frame rail, about at front cylinder head. Plugs in to a connector with two wires, Green with red stripe and Light Green with red stripe. Unplug the diode, and make up a jumper to ground the Green with red stripe wire. Presto, no clutch switch. :mrgreen:

Downside is no neutral switch, either, but retaining that while bypassing the clutch switch would be more complicated, as the original layout gives priority to the clutch switch.

Thanks, no neutral switch means no neutral light I imagine? It is not so much I don't want it as I don't care, if I need it to keep the light I will figure out which pins to use and wire it in.

Spent some time today solving seat release, choke lever and started designing my enclosed belly pan. Does anyone know if it needs to be enclosed all the way back under the exhaust collector?

Making a foam form, I will be bonding the seam so this will be a one piece belly pan.

Most bellypans I've seen go from the very front back to the swingarm. They have to be large enough to hold an entire engine's worth of oil in case of a blow.
