wr 400 carby

hi,

can anyone tell me if the vacuum plate and throttle body that it sits on should have a bit of free play back and fourth,in the carby ( 98 wr400 ) i have cracked 1 vacuum plate that was only six months old, is this free play normal.

My other bike an 04 wr450 does have the same amount of free play but has never cracked a vacuum plate

Thanks pete pj

Yes, some freeplay is normal. Sadly, the old style FCR has a history of cracking slide plates. And unfortunately, there is no upgraded part to prevent future cracked slides.

Thanks mate i thought that would be the case
