Ordering the 351 kit - urgent question!
Hey guys, spoke to bill today and about to order the 351 kit. Question: is it absolutely necessary to get the TM33/34 pumper carb along with the bore kit? Folks that have the big bore with the stock carb, what are your thoughts?
The carb costs almost as much as the bore itself so I'm wondering if its a must have. Thanks a lot for your thought!

I guess what I meant to ask is if the performance gain associated with the pumper carb made it a worthwhile expense. I didn't mean if it was strictly necessary, more like us it recommended. Thanks guys.

Pumper carb is an upgrade to the stock carb, unnecessary, but then so is the 351.
I ordered Bill's carb with the 351, had to redue jetting due to 3,300-11,000 ft elevation, but it all is well now. If you looking for just a little more performance, you can just do the carb.

Correct me if I'm wrong but the biggest advantage to the pumper carb is the quicker throttle response. Right?
I have the 351 and have not felt the need for a pumper carb , but I've never ridden a KLX with one and felt the difference it makes.
Is the performance gain similar in "wow" factor to the big bore? By that , I mean is it as noticeable as the BB upgrade?

I tell ya...one of my biggest regrets with my KLX was not going to this carb sooner. I was one of those who was very skeptical that the carb would be that much of a benefit. And while it may not be the supercharged, firebreathing addition that turns it into a KTM530, it is an oh-so-pleasant component that I have not regretted for a second. The great jetting homework that other fine forum members had hammered out for this carb made the whole deal just about plug-and-play.
