congrats :lol:
about breaking in the bike
i know you must do a heatcycle 3 times
first time 10 min cool down
second 20 min then cooldown
3rd 20 min then cooldown
dont break it in like a sissy :-Ddont break it in @fullthrottle
have fun :lol:
-
is that just starting it and letting it idle or is that riding it????

you sure have to ride it :-)
but just not @ full throttle
more kind a playing around with the throttle till halfway
accelerate/decelerate shift a bit here&there
by the last cooldown everything is settled and you can haul :mrgreen:

When I heat cycle I just let it idle outside my shop until it heats up fully. I do that 6X before I ride it.
In the old days at the beginning of MX season we would have to show up at 1st race with new bikes not broken in. We would heat cycle them in the back of the truck while we were driving the 500miles to the race, then complete the break in in practise. cam.

Both! Do a few heat cycles idling. Then ride it easy for a couple cycles. It will be ready to rip then, but will still need a few riding hours to be perfect.
Make sure slide closes all the way before starting. When seating rings, they can heat up and run without spark. If you're slide is open any,there is no way to control throttle or to kill the engine. (Words of experience)

awsome guys now whats the slide??? i spent 2 on a piston and prolly 80 on machining the jug not to mention the gasket set and plugs about 70.. i would hate to blow it up again :x but im ready to haul some ass!!!!!!!!!!!!!!!!!!!!!! :mrgreen:

The carb slide is what you see going up and down in the barrel of the carb when you are hitting the throttle. Make sure your idle screw is not bottomed out and there is just a little slack in the throttle cable, also. Sometimes guys will turn their idle screw all the way in trying to keep it running. Then they might tighten the cable to make it idle. That will open the slide too much and may blow it up during break in.
