Thanks ALL!!
She runs real well at less than 65/7000 rpm but surges at higher rpms.
Mr/Mrs B is it mixture? I cleaned the filter.
Heard of this b4?

Say J.B (And other friends)
Did my cheque arrive?
Allso I'm experiencing A surge in speed -- slower faster topping out at about 8,000 rpm starting about 6500 rpm (mixture? jetting trouble?) Speed surges when I try to open the throttle up ... I'm happy so far with the low speed performance and the cool starting...( I hope this continues through next winter)
I'm going to change the spark plug and air filter to try to get my top speed back I was over 100 mph a couple times B4 the carb switch... And able to open the throttle fully with ease.
Any other ideas .. It's a 2007 250 with your TM33/34 no other mod at all. And of course SPEED IS THE POINT OF THE WHOLE THING! I need the Top speed back!!!
Thanks all Especially Joann & Bill!
