Unfortunately i ran out of time to do a frame build. Ill likely do that over the winter. I plan on monoshocking and running a wishbone setup.

Re: Race Bike Build - Oct 12th/13th due date

Lots of tangible progress tonight

That stingers will absolutely break without super good reinforcements. The baffle flange is also shit and always cracks off. I would definitely not skimp on the gussets.

Yup, im on it. Plan is to run a triangle support and rubber mount it to the upper rear shock mount

Re: Race Bike Build - Oct 12th/13th due date

Rad, it looks super good, any reason in particular you wanted a right side routed exhaust? Is the track all lefts? (edited)

You got it. About 10-11 turns and 1 being a right

awesome looking buildright hand exhaust looks bad ass, what pump are you using for you WC setup ?

No pump for the races, im relying on thermosiphon. Max head temp has been 284 degrees. I have a water temp gauge that ill be running to compare water temps.

Though anecdotal, the return hose is significantly cooler than the hot hose. Enough of a temp change that you cant hold the hot hose for more than 5 seconds.

Delicious heater hose burn

Re: Race Bike Build - Oct 12th/13th due date

That looks like it’s too hot

Re: Race Bike Build - Oct 12th/13th due date

In just the right place , too .

I had to use a heat gun to install the 5/8 hose line. So not actual running temps.

Interesting thermosiphon systems do seem to to work well, a bosch pump always seems better in my mind

Re: Race Bike Build - Oct 12th/13th due date

Also what reedblock you running, you could put in a spacer and run something larger maybe?

Re: Race Bike Build - Oct 12th/13th due date

Did some fun stuff tonight.

Mars donated the fairing and clipons.

The stipulation being i made my own shims and kept the sticker.

you went real polar opposite on the ergo and geometry advice, but it looks cool.

So its an interesting topic that ive put some thought into. My original bars were too short, but that included some pinto ebr's that are hella short.

Moving over to tomos ebrs and a magnum swingarm really changes the angles, distances, and overally geometry. So while you see dropped bars on a maxi, their relative height is different from just throwing clubmans on a stock maxi.

Before I shorten cables ill experiment with handlebars. After doing my 10 mile shakedown i had no hand or wrist fatigue.

Ill be swapping my pegs out too. I have some dirtbike ones that will be going on with multiple mounting points so I have options. (edited)

It's less about fatigue and more about body position on something with a wheelbase that short

Is there a standard formula or measurement I can replicate between the axles of the wheels for best handling? Going to have to take rake into account too im guessing

Re: Race Bike Build - Oct 12th/13th due date

Have you ever crashed a bike before? Just asking. An aluminum fairing with sharp corners could remove some much needed body parts. For you and whoever you crash into, or crashes into you.

I'm not joking. I've seen people low-side into a corner, taking out the guy next to them, who then topples over their bike.

I personally low sided a corner (not my fault, hit oil from a previous wreck) and my handlebars grabbed my ankle and dragged me a few feet. Also jabbed myself in the gut with a grip once.

Also hit soft sand going off the track and went over the bars. But slowly, not a full on flip.

A fairing like that could turn a mellow crash into something serious. And, with the low-ish speeds and no long straights, wouldn't do much for aerodynamics anyway, and just adds weight.

Hmm all valid points. Yea, ive crashed and walked away with some rash and a concussion, no gutting luckily.

I have some safety edge rubber for it, so the slicing and dicing wont be an issue.

Maybe ill just leave this be as a street set up

At least put a good sized radius on those upper corners , before you put the fake edge on . That thing could still take you out , even after the trim fob .

Re: Race Bike Build - Oct 12th/13th due date

- Continued to chop and reinforce frame

- tap shock mount tube to m10

- tires and tubes

- fork brace

- tail light and bracket for reg sticker

- inspect wiring and solder all connections

- solder brake and clutch cable

- finished wiring headlight

- mount race seat and put some padding on it

- sipe rear brake pads

- nord locked intake bolts

Made a new throttle cable and housing tonight. Measured the slide with a depth gauge and got some great snappy action.

Re: Race Bike Build - Oct 12th/13th due date

Did you chop the tubes on that front end or is it stock height? Looking good! Its comming together nicely!

No chopping, the upper portion of the stancions are about 3" above the triple tree. I have to measure my rake and adjust them

Pick up this book if you can.

Suspension in my opinion is one of the most important parts of setting up a race bike. Before any performance modifications etc. a bike needs to be set up for the individual rider.

In all the racing series I'm in, what wins races is suspension since most of the riders are all within a 2-3 seconds of each other in lap times and skill. The bikes are for the most part all pretty equal in power. Comes down to setup and style the rider can be fastest and comfortable at.

I was building up my Derbi for Cherry Valley, so lets meet up at the next race after this one. Also, feel free if you're ever in Brooklyn to hit me up and come have a beer at my shop.
