New rebel 250 guy here , 67 mph engine cuts off

Hi all. Harley guy here. I know. Bought 2 rebels for boys to learn on. Issue I’m having . 2004 Rebel 250. Runs, starts , idles great . Last 2 rides he was going about 65mph and it just dies. Have to come to almost complete stop to get it to run again. It’s a CA model. I’ve unhooked canister , added and removed fuel filter , sea foam, ran it with no air filter , fresh gas. Will cruise all day 55-60. Spark plugs look good. Ive read a ton on here , and have it narrowed down to either CDI, or Main jet in carb. I can do most things , carb is not one. Replacing CDI Tuesday. Looking for your expert opinions. No kinks in air lines either . For now he shouldn’t be going that fast anyway but he said he’s just trying to keep up with me . Noted .. other 2004 runs fine . Not cA model. Thanks in advance

Doubt it is CDI or you would loose top end RPM in other gears
CDI doesn't know what speed bike is traveling.
try running it without gas cap locked down, could be tank isn't venting properly causing a vacuum thus fuel starvation..

I'd also consider pulling the petcock, check tank screen isn't partially plugged..

I only have one key , and can’t get the key out when I have it off . Lol wanted to try that . I’ll take tank off tomorrow and verify no kinks under tank . Everything past tank looks good

With cap off press the lock pins in as you turn key there is a point where key will turn and can be extracted

yes pull out of tank, which needs to be empty to pull petcock off.

pps pressing/pinching against rubber seal towards top at 2 points above pins is the trick to release key, been a while since I have had to do it..

or as you have 2 rebels put the cap on other one to remove key while setting non-cali bike cap with it's key in it during the road test of California bike...

More details of "and it dies" might help.
are the lights still on when it dies
is it half/firing/choking/limping or just a complete no more spark and the exhaust reeks of fuel?

Well I can’t see the lights when it happens , it’s like you hit the kill swing for a few , i down shift let out clutch fires back up , but it’s in 3rd at this time and I’m good as long as I stay under 65-67. Sometimes it comes completely stalls and I have to stop and fire bike back up . Never not fired . I didn’t notice last night , I had gas off . Took fuel line off and turned gas on. No gas would come out. As soon as I hooked up to carb and start , you see gas flow down clear tube . I’m going to ride it tonight with cap off and see what happens . If that works , going to drill holes in cap.

If the cap needs to be vented, only one very small hole is needed. Drill the hole off center and just through the bottom of the cap.

Keepin' all the left over parts. Gonna use 'em to build another bike!
