Keep us posted. My son will be racing his CBR 250 and and RS 125 this year in WERA as well.

 

how olds your boy, sounds like you'll have the weight advantage over me.

 

yay 2013 colours on the forum finally...
Congrats on the purchase.. and technically your bike is supposed clock atleast 3-5 miles as part of your dealer's PDI (Pre Delivery Inspection). I dont think theyve tested it before delivering it to ya.

 

I told them I wanted it in the crate. They took it out anyway.

I'm going to have to drain the oil to safety wire the drain plug.
I'm going to drain the coolant and use distilled water and water wetter.
I'm going to install a stainless braided front brake line and use RBF600 fluid.
I'm draining the gas and running either 93 or MR12. I need to double check the rules on fuel and then get the bike mapped for that fuel.

Kinda a waste of fluids and time spent putting the mirrors on and what ever else they do for a PDI. The engine starts and the bike runs, that's all that needed to be checked.

 

I took the gas cap off and thought it broke it. The whole thing comes off?? No hinges? So cheap, I need to find a key-less gas cap that the ripper cap on my tuff jug fits into.

 

have you tried to fill up the 250? this is a great bike but the only downfall is filling it up with fuel. there is a metal diverter in the tank that makes filling this bike quickly is almost impossible.

 

Lol that's one disadvantage. You gotta either hold it or keep it somewhere while you fill her up. Not a big hassle but couldve been avoided by the designer.

I am planning on racing this summer too.

My son will be 12 in a couple of months. He races in the North Central Region of Wera.

 

Thinking of buying one and building for my 17 daughter and 14 son. They have expressed interest and gives me good excuse Thank you for sharing learning a lot already.

 

I would do some research befor removing the tank filler baffle. I suspect that it is there to protect the evap system. Pre evap motorcycles had vented caps , now system venting is handled thru evap. The air space at the top of the tank allows room for fuel expansion, if the baffle were removed , the tank filled to the top and then warmed in the sun I fear the pressure may push raw fuel into the evap system. All new cars warn about not topping off at fillups to protect evap systems. This may not be any concern with the CBR but I would check befor making any mods.

 

What did you get in your tool kits?

I got an allen wrench and a metal strap of some sort.

Removed all the bodywork and gas tank. Starting to safety wire the bike. I got the clipons and rear sets from Woodcraft and started putting them on.

This is a baffle inside the gas tank, looking at it from the bottom with the fuel pump removed. I will be leaving it there but if anyone wanted to remove it...

is there anything on the fuel pump that would be protected by that baffle?

 

You got an allen wrench? Lucky bastard. The metal wire is a helmet strap.

Thanks for the great thread! I just picked up a used 2012 (536 miles?!) to race this season with M1GP here in SoCal. They just announced the addition of a Honda250r class with a contingency program...REAL cash prizes for the podium finishers! I'm hoping that I can get an early jump on some of the really good racers (and those pesky lightweight kids) who I expect will start showing up once word gets out that there is cash involved. ;-)

 

I need to become expert?...

WERA from 2012

That's the main reason I'm on a CBR...
FYI with Motoseries they combine exp/nov and pay 5 rounds (one of the 2 rounds per weekend)

 

Last night I also got the air box drain sealed with a cap; 3/8" or 10mm. The drain fitting has a rubber boot with a slot cut in it from the factory.

The pink hose is a part of the crank case breather and acts as a catch can. It is plugged at the end and I will leave it as is hanging above the belly pan. I will watch it and keep it drained if it collects oil.

 

Did some checking this morning and as I suspected if the fuel tank were to be filled to the top with no air space the evap vapor line would be flooded. As there appears to be no valve other than the purge solenoid which is down stream of the canister, the canister would fill with liquid.

 

Glad to see another cbr out there. I raced the cbr in WERA last year along with a buddy and will be racing it this year as well. There's a post with some video and pictures around here somewhere... Great bike but be prepared to get passed on any straight... And on a 250...you quickly realize if it ain't a turn, it's a straight vs. how it is on the bigger bikes... Not sure what region you are in but I'm here in the Southeast. Good Luck!

 

I saw your thread and watched your videos. Did Thermosman set up your suspension? He did my 600 last year at CMP. A friend of mine called him in because of a leaking fork seal and I borrowed him after that for a setup. I have questions about the geometry, what's the preferred or sweet setup? Lower or raise the front/rear? I see the fork tubes up through the top clamp a few inches on other race bikes. Doesn't mean anything unless you know what's inside the forks too though.

 

Thermosman did the emulators and springs up front for me and he got me a JRi shock for the rear. He's the only person that touches my suspension...period. Not much selection for the rear with any adjustments unless you spend a grand+ for the triple clicker which is overkill to me. With the suspension changes, the bike is noticeably faster through turns than the ninja with me on it and I'm not small... 230lbs before gear.

Zero changes to geometry. The bike is small, light, low power so geometry isn't quite the concern as on a big bike. I battled with my bmw s1000rr for a year to find a good setup! This lil thing, you just throw it where you want it to go... Ground clearance is a concern though with solid pegs and also the kickstand mount bracket. That and the wallowing through turns is the compelling argument for the rear shock swap just to keep it planted and steady.

The craziest part is getting used to how you ride it so differently than a big bike. I still race my 1000 so it's odd switching back and forth. Braking markers for the big bike are shift points on the lil bike! I am going as fast or faster through the turns on the lil bike as I am on the big one. I've confirmed this with gps data... Sometimes 10mph difference mid corner!

The kickstand bracket is going to be cut off the frame.

 

I bought the Ohlins from STG.

Öhlins Shock Kawasaki Honda 250R 2011-12 from SportbikeTrackGear.com

Did NOT pay anywhere near close to $900

Race Tech up front? That's next after I can get a pin made for my tree stand. Forks are going to them for service.

 

if you don't mind, how much did the ohlins cost?

 

Call STG and ask for Jason.

 

I would send the forks to Thermosman personally and let him do them. Nothing against racetech but Thermosman is the one at the track every weekend with the hands-on race knowledge. Also, what he did in the forks vs. what racetech does is exactly opposite and I know his setup works... I didn't pay anthing near $900 either for the shock. Does the ohlins have rebound only or no adjustments? The JRi only has rebound adjustment, no compression.

I'm using the same pin for the honda as my gsxr1000...it's not a snug fit but it works. What tires are you looking at using?

 

The pins kinda fit, at least the fat part does that goes into the stand. I might have something machined, I want to send the rear rotor to the shop to be cut down too.

I don't have the Ohlins yet, but the site says

I already bought the Dunlop unbeaten 02's from race tire service. I have to have them mounted...

Results for NINJA 250R


I might just give Thermosman a call and send my forks down.

 

Does the clutch switch matter on this bike? On 04+ GSXR it puts the ecu in a neutral map when jumped out. I want to remove the left side light and horn buttons but the clutch switch wires are in the same connector and harness...

 

Tom, looks good so far! I'll try and be keeping an eye on your build progress. Jason is at my desk checking it out with me and says thanks for the good word.

 

If it's the ohlins I was looking at...I don't think there are any adjustments...just change of spring rate but it should still be a vast improvement over stock! I called ohlins directly and talked to the techs there about it 3 months ago. Basically they picked a shock that is usually a part of a dual rear shock setup on older bikes and cruisers that would also match up to our lil bike and are using it. Although the guy out west I think is working with them on another option for a ttx version?

I removed the clutch switch without issue. I also recommend the -1 for the front sprocket. TJ at riders discount can help you out if STG doesn't carry it.

And I love the unbeaten's! A bunch of guys love the bridgestones too though so? Atleast there are options!
