first i need to know thw size of the stock carb and make and model of keihin replacement . next it make an awful clunking when starter engages like a rod smacking cylinder wall but sounds when running, is this normal? its a 1999 and anything to check or watch for? thanks in advance. oh wait do they all vibrate pretty bad at high rpms? thanks again

 

I have a 05 raptor 350 it vibrate's alot as well and i have a friend wit a warrior it clunk's like he!! every time he crank's it not sure what it is i was like you i when i first heard it i was at ahh i was thinking to myself how could anyone let a engine get that wore out lol but it only clunked about 2-3 times then bam it crunk up and sounded great im not sure what it is that causes it but his has been doing it for over a year and still is fine noisy as he!! but is fine. And as i said the 350 warrior/raptor motor doe's vibrate alot dont sweat that it's fine. GOOD RIDEING TO YOU AND HER ```Jeremy

 

The carb on the warrior is a 36mm. They do vibrate and therefore you need to check motor mounts periodicly. Especially the head mount as they break constantly. I do not know of the noise your explaining, my Warrior never made any noise like that. Good luck.
