Newbie building a track bike

htdub · May 7th, 2012, 03:56 PM

Ok, finally found my 250. I'm going to be tracking it this year, with aspirations to race next year. Bike isn't here yet, its' on a hauler.

I've red thru some of the awesome race bike build threads, taking notes.
Here's what I have planned hoping to get some feedback.

Bike is missing a couple of parts.

Front Fairing Stay (Ordered online for $99)
lower fairing brackets (ebay, $20)

Racey Parts

Hotbodies Fairing (Ordered from Hotmoto
Driven Clipons - Ordered Woodcraft Ones with the risers.
bohemianracing rearsets or the sv racing rearsets (local guy)
Sato Frame Sliders - picked up TREx sliders
EBC pads - Ordered Versah Pads
Some sort of Jet kit - picked up a Factory pro of another ninjette member
BT003 RS tires - Ordered a front tire, had a rear already.
Fork Springs with bit heavier fork oil.
Stock Exhaust (WMRC rules require stock exahust from any bike) May look for a oem Titanium pipe from some other bike.
I have a GSXR shock, and 8.1KG spring, i'm (160lbs with gear), i'll wait until dog bones are made available.
Safety Wire. Cut off the centerstand nub thing.

I think that'll get me on the track to get seat time before making any serious $$$ upgrades.

Get vesrah pads and some sort of steel braided brake line, then you'll be set. The frame sliders are optional, these bikes crash pretty well without them, and if you do use heavier fork oil without getting emulators, just go slightly up in oil weight.

Trailerboy531 · May 7th, 2012, 04:38 PM

sliders no
vesrah yes.

Listen to Steve, he is racing jesus.

alex.s · May 7th, 2012, 05:45 PM

you also need awesome brand stickers to make it look like you are sponsored. it makes the other racers feel slow.

htdub · May 7th, 2012, 09:32 PM

No sliders huh.

Trailerboy531 · May 7th, 2012, 10:06 PM

The bikes crash pretty well and you dont want a slider to dig in once it hits dirt and then flip the bike or bend the frame.

abhijitz · May 7th, 2012, 10:10 PM

Yes, no sliders. On this little bike, the way Sato sliders are designed, if the bike crashes and the slider gets caught, it is going to do more damage to the unibody frame.

Driven Clipons : Limited adjustability. Front gets lowered. If you ever use a rear height adjustable shock you will miss front end adjustability. Go with woodcraft with the 2.5" risers. I can hook you up on a smoking deal.

Tires : Pirelli tires my friend. The new diablo rosso 2 race with sc2 front. Working like a charm. I am dropping seconds every trackday. This tire just sticks.

Brake Pads : EBC Pro HH is working fine for me.

Rear Shock : Give the RPM shock a try. I love it. It is stock shock length though.

Rearsets : Bohemain Racing rearsets works perfect. Under 200 bucks and you very sturdy.

Get some front steel brake lines as well.

Jiggyfly · May 7th, 2012, 11:31 PM

"centerstand nub thingy"= kickstand mount? If so, then yes!
Otherwise you're pretty right on. Listen to the experienced racers.
They've wasted time & money sorting through what works & what doesn't.

I commend you as a newb, for doing your homework.

One more bit of advice: skip the track days & start racing. You'll learn more in 2 race weekends then an entire season of track days. People tend to get stuck doing trackdays.

SPG · May 8th, 2012, 05:08 PM

Also, with the pipe and airbox, the factory 98 main jet is pretty close and still a little rich, a 95 might work better for you in the summer. Stock needlee shimed up .040 (two washers) should be all you need to have the bike running well.

Also, double check the dogbones with your rules. If you race Ninja Cup in WMRRA or OMRRA they are not allowed. Other classes would be ok.

htdub · May 9th, 2012, 01:00 PM

The bike is a Cali bike, should i be yanking off emissions bits?

smokinsingle · May 9th, 2012, 06:11 PM

Oh yeah...ditch it all, run vents to catchcans, and block off the valve cover port.

Shogun framesliders help to brace the frame not just hold a delrin puck, it's almost like cheating

Driven clipons limited adjustability? Thought they were more adjustable than woodcraft?

abhijitz · May 9th, 2012, 09:13 PM

Kind of. IMO, the 10 degree vertical adjustability is not a real necessity for racebike. You would want the handlebars towards the front of the bike (lateral adjustment). Woodcraft provides option spacers to adjust that, but not needed.

Biggest advantage of woodcraft is the fork brace/mount is a 2-piece than 1-piece. Really makes assembly/disassembly much easier.

On all the racebikes/ trackbikes i have seen all of them use woodcraft with risers. Maybe someone who is using Driven can chime in.

TGRIFF · May 10th, 2012, 06:32 AM

I look forward to seeing this build. I will be building a race 250 this year as well.

htdub · May 11th, 2012, 04:25 PM

Ordered a few things

Hotbodies Color Form Fairings from Hotmoto Great deal.
Going to vinyl it up and friend will sharpie some artwork on for fun.

BT003RS front and Woodcraft Clipons from local shop, Bayside

Will run BT's until I can get good and have funds for warmers, i'll track some used ones down.

My racing orgs have strict exhaust rules. Has to be a stock/oem muffler from any bike. I was thinking of fitting titanium pipe like this 954 oem one on.
I'll have to check the pipe diameters, but thought it might work and weight savings would be pretty good.

Thoughts?

Awesome thread.

htdub · May 25th, 2012, 11:15 PM

Got my bike mostly sorted.

Just finishing up putting on the hotbodies and tires.

Am I suppose to drill the bolt for the oil filter cover?

smokinsingle · May 26th, 2012, 07:16 AM

Yes, and the drains, both of them....Can't hurt to do the water pump drain as well

You planning race this season or track days? Few other friends are doing 250's as well.

5evenz · June 2nd, 2012, 09:55 AM

just track as of yet, we'll see how the season goes.

I wasted all my dough on girls rather than get a track bike up and rolling.
....rookie mistake. :/

htdub · June 4th, 2012, 04:00 PM

I'm doing a couple of the upcoming at Mission and Pitt Meadows, would be good to see another 250 rider.

htdub · June 6th, 2012, 07:45 AM

What would be more logical, rear shock upgrade or set of used tires warmers/generator?

abhijitz · June 18th, 2012, 10:29 PM

Rear shock upgrade for SURE .... To start off, you really do not need tire warmers for the Ninjette. A hard lap will generate enough heat.

The stock rear shock is easily capable of track record pace. I've seen it over and over again. That is, unless you are 200+ pounds. I would spend the money elsewhere. Just my 0.02.

OneSock · June 28th, 2012, 04:13 PM

How are getting your safety wire bolts, are drilling yourself or buying?

I looked the the rules book for my local racing org. Then read rexbo's thread.

Friend helped me drill, go slow, and buy lots extra bits.
