Throttle Blubber

[yortz]

:ohmy: Just picked up my new bike, did the first part of the breaking in process. It has a pretty significant blubber at about 1/8 throttle. Plug seems clean, 1140 elevation, any ideas on this problem?

Thanx

At the top of this forum there is a 'sticky' post entitled: 'Every kdx rider should read...'

Check it out.

On CDave's site you will find helpful information regarding starting points for bike jetting.

If by 'blubber' you are referring to what a happy 2-stroke does under no load...4-stroking..that's not a problem.

Not to be confused with 4-stroking under load because of a too rich/plug loaded situation.

re: 'plug seems clean'

With OEM jetting, it won't stay that way! OEM jetting is untenable.
