We are looking for a customers YFZ450R TB to bore out. The boring will be free but might take a week or 2 to complete. Its a new service TQS ATV will be offering to the public very shortly.

Please PM me for the details if you are interested. The work that is done will be top notch I can guarantee you this. We currently offer the service for FCR Carbs and Raptor 700 TB's!


Thanks Guys

steve i sent you a message im in redding and would love you to do this.

TB = Trottle Body? If so, what sort of added performance do you get?

Hey Guys,

lots of interest in this thanks. We did get a TB headed our way. We will have bored TB services available hopefully within a week.


Thanks again

i cant wait to get it back to see what kinda gains i have

Steve,

Did you get my message? I sent you a tell. I am interested and willing to send mine your way.

Definitely interested in having this done! How much will you be charging? What size are you boring them to? Let me know when you have that one completed and are ready for another one!

These are details that we will be figuring out after we are done with the initial TB.

I expect the standard to be a 44mm bore and cost to be approximately $135 shipped

What is the stock size, and what kind of gains are you expecting to see?
Im only a little over 2 hours away, so would you be able to do it while i waited if i were to bring it up?

We dont actually do it in-house we sub the work out to a machinist. I'm trying to get my hands on a TB to keep in stock as a core so you guys have zero downtime.

OEM size is 42mm

its not hurting my feelings being down

How big can you go on the boring? and what would the price difference be?

yeah whatsthe price, and size youll go to?

yes bigger is always better . jimmy he is like an hour from me maybe like 4 hours from you lol

We will have all the details worked out as soon as ltrkillers TB is done.

your house is only like 2 hours from me little man

ya when u go 85...........

He was able to safely bore the TB out to a 45mm. We will have 44mm and 45mm options available as of now. I will post pictures soon. Price is $135 shipped.

So if my YFZ450R has a PC3, pipe, porting, cams and high comp piston what will a 44 or 45mm TB do for me?

I havent been able to test the power increase yet and probably wont for a while. However we have done tests on the YFZ450 carbs and the Raptor 700 TB's and the increase has been more than worth the cost providing great gains.

i received the tb today and all i can say is wow looks amazing cant wait to get it on the quad this weekend i will let every one know how it feels on the butt dyno i got a idea its gunna be great thanks again steve
