does anybody know where i can get a jetting chart for an 87 warrior with a white brothers e- series exahust????

i've been all over the net and can't find a damn thing.

 

have you tried to look for a downloadable manual or something like that .......

 

i've tried everything and nothing

 

well man i donno inless you bought a written manual.....i would think your local yamaha dealer would help you out 2

 

i have the service manual for the bike. i just want to know what my jet size needs to be for the exausht the exuahst came with the bike when i bought it and there is a 150 jet in it i just want to make sure that's the right size. i'm only about 100 and some feet above sea level.

 

if all you have is the white bro's exsh, call up white brothers and ask them...any company selling a pipe will tell you what jets you need...walla!

 

i called up white bros. today and they said as of today they are shutting down there services and will no longer be selling thier products. you can't even talk to a rep. for questions.

maybe i'll try calling a dealer who deals white bros. exauhst like parts unlimited or some damn place.

 

rocky mountain atv/mc try them...hm i wonder why there shutting down

 

i dunno i was wondering the same thing. i dunno if it's just sales or if their stopping their production line all together, i have no idea. i'll have to try them.

 

I dont think anyone could publish a chart in good conscience like what you are after. There are just too many variables to say for sure what jet you will need. White Bros couldn't tell you exactly even if they wanted to. The best they could do is give you a range that seems to work for everyone else with your exact setup and altitude. Its up to you to look at your plug and compare that to how it rides and try to decide if you need a bigger or smaller jet. And to further complicate matters, the lack of lead in the gas now days makes it difficult to accurately read the plug. So, now you have to become your own mechanic or find someone else you can trust.

rockymountain, as far as I can tell, is just a bunch of sales people taking calls. You'd have to either get lucky, or go pretty far up the chain to find someone that really might know.

Does your quad run ok? How does the plug look? What type of carb do you have? What kind of air filter and is it dirty? Do you have your valves adjusted properly? Is your cam stock? Are you buring any oil? Has the piston ever been replaced? 1987 was a long time ago.... Plenty of time to either be burning oil or replacing rings n valves.
