EX250/250R Racing Everything you need to know

That's a trip to the Applebee's for you and a lucky lady...just sayin'.

 

The 710 claims it brings all the boys to the yard.

 

baconologist, I'm confused on the plugs for the older ecu. I bought a 92. I have a 6plug with 4 pins and a 4 plug with 4 pins. The diagram on the link only shows 7 wires??? Thanks.

 

No idea.
I ran across that link and just remembered it was a possible option. It isn't FSS legal, and Sportisi was still open when I built mine.

I can post your question on Ninjette if you like.

 

Sure. I googled the ecu # and only thing that came up was for zzr250. So I'm wondering if it's from a European model some how?? Thanks

 

I have more if you need it, full wiring diagram etc. Haven't done it yet but did receive my gen1 cdi yesterday from ebay. $35
Edit: I'm in South FL, so it is legal in Thunderbike

 

32F 26R

 

Ok, I think I figured it out. I know I'm a little slow but I eventually catch up. Lol. Thanks Lance

 

Makin' it to NJ on it?

 

I wish, I won't be ready until VIR.

 

Lance, I have a programmable ECU from BRT. It's in great shape and comes with the programmer and all the instructions. I just plugged it in to my bike to make sure it works. I was just about to put it in the classifieds. If you want it, I'll hold off posting it. $150.00 shipped.

 

Just wanted to set the tone for '17...

 

Travis, did you dump the Grom for a Ninjette?

 

I did.
It's probably gonna take a few weekends to harness all that extra HP but I'll take it slow.

 

Can both the intake and exhaust valves be lapped? I'm reading that some valves are case hardened and should not be lapped. Cannot seem to find the info on the 250 valves.

 

not under the FSS rules

 

I'm in South FL, they mangled the 250 class down here. It's now a 300SB class. I blew a head gasket, and this will be my first ever gasket replacement, so I figure while I'm in there, I will clean up the valve seats. Lots of reading, but I cannot find info on the material of the valves.

On a side note, I've been told I have a "stuck intake valve" on my EX500 so I'm into the same process for that bike and found that the exhaust valves can be lapped, but the intake valves are case hardened and you should not lap an old (used) case hardened valve, as it will quickly wear through the hardening.

 

Can a super stock 250 ninja go 2 hours on 1 tank of gas or do you need to refuel? Thanks Lance

 

Doubtful, unless you're on the highway.

We did the first 2-hour 250 endurance at Jennings on one tank, but just barely.
