Got to tell ya, the weather here in west central Indiana has been great for scoot riden. The temp. has been in the low 90's and the wind hasn't been a problem. On the way to work Tuesday, I had the old problem return, the needle sticking in the carb. Now I've got to tell you that I did have the throddle wide open at one point on I-74 and I actually new I was in trouble. ::)Yep, Pulled up to a 4-way stop, gave the bad boy some throddle and he bogged like he was flooding out. Pulled over to the side, raised the seat, unscrewed the batt. cover, tapped a few times on top of the gold cover of the carb. and he was good as new. Lessoned learned, (don't open throddle while ridding.)
Since the weather has been coperating, I now have 7,527 miles on my Roketa MC-250-B and it is getting 64.7 miles per gal at an average of 60- 65 mph. ;D

Here's a possibility that might make you feel a little better, but JUST a possibility. WOT for extended periods causes a loss of vacuum in the intake system from no resistance at the butterfly. This is especially true if you're going downhill at WOT. There's a couple things that can make it run like crap for a bit, one is The vacuum fuel valve closes, or the vacuum fuel pump output drops. It SEEMS like your flooded but it's really loss of fuel till the pressure normalizes. Also, if you've ever felt your crankcase breather without a hose when your riding, a lot of air comes out of it from positive crankcase pressure. Long periods at WOT, especially downhill, causes oil to push past the rings into the head causing it to run like crap till the oil seeps back down. This is not a good situation and can cause damage. WOT is fine but the little guys really aren't made to be hammered, just like your car or any other engine. Rich

only small motors designed for WOT are weed wackers chainsaws and outboard motors. and I believe they all have some safety factor built in so you won't get engine speed that destroys the motor.

Luke , I normally run about 60-65 mph in a 60 mph speed zone to work but when I get on the free way I'm booking it and there isn't much throttle left. The other day when the needle stuck, I just tried opening the throttle to see how much twist it would take to get there. I found out, not very far....... No, I don't recommend WOT anytime but I just needed to know. Curiosity killed the Cat.
John , I totally agree with you for I have them all. Still weed whacker, Still Farm Boss and a Yamaha 25 hp outboard motor. Wacko weeds, cut firewood, and GONE FISHING.

OK Bashan, I'll try not ride with the throddle wide open anymore. What I'm going to do is, White tape on throddle meets White tape on bar--60 mph. White tape on throddle meets green tape on bar-- 65 mph. White tape meets yellow tape on bar---- Slow it down, you're going too damn fast. These scooter speed-o-meeters aren't rite anyway....

You can do WOT, I do all the time. You just have to back off the little guy once in a while and let it settle down a bit. rerugulate the vacuum and let the oil settle down. Bashan

The CDI on my TGB Delivery 50cc will 'feather' the engine at 45mph, the bike is modded, as
soon as the rpm's drop back to a safe level the engine runs normally. A good safety feature.
My TGB Delivery 150cc has a sweet spot at about 55, can hit 65, GPS checked, but I do not
run at WOT for more than very brief moments. 3/4 throttle gets me 55-60 and that is fine for
my riding conditions.
