my local dealers only know how to place parts orders if the part # is in their computer. Guess what, no part # for small mikuni jets and they don't have them in stock. That's CA for ya.

btw, not looking for dynojet.
thanks.

 

I just put in some larger main jets. Was lucky enough to find them at the dealer. He says there are 2 styles of main jets. One is round with a slot across it (for screwdriver) and the other is hex head. Mine had the round ones. He did not have all the sizes I wanted and said if I call around, any Mukuni 4 stroke carbs would work but to be sure the were for a 4 stroke. I went from a 140 and 145 combo to 145 and 150 combo in hopes of stopping the carbs from blowing off on my Raptor. I am running an FMF muffler. Have not had a chance to ride it yet. He did not have any pilot jets so I will try that next. I have seen some post saying they ordered them from Sudco I think.

i got mine off ebay..its a dynojet stage 2.
$83 dollars shipped to my door..just goto search on ebay and then type in Yamaha Raptor..it should come up..go to my site to access ebay from the home page it will take you right to it

 

I got my Dynojet kit from Magic Racing (www.magicracing.com if you need a number). Thats all I could find, $69 for that. They also had 27.5 pilots for $4.00 each, so I bought 2 of those.

So I know Magic carries the correct pilots, but I have yet to find anyone that carries the mains not in the dynojet kit..

I have never bought any yet, but some guys were getting them from Sudco. That is where I am going to try when I order mine. I think you can get the K&N jet kit which is a Dyno-Jet kit from Rocky Mountain ATV for about $59 bucks.

Thanks Mudrat & Charles!!
Your reply was exactly what I was looking for. Sudco and carbparts are just the ticket.

Everyone is talking about "jet kits". What comes in them that makes them so expensive when you can get mains for $3 and Pilots for $4? What am I overlooking?

 

The jets kits are overpriced...

but you get 7 main jets, new needles, new springs etc... it's not a hugely horrible deal as some people make it out to be..

they've also done alot of the work for you as a starting basis for jetting.. and the new needles are supposed to help the mid range some...

all in all I'd have prefered to found jets.. but when I couldn't I just bought the kit
