Selling only because I’m switching brand, new partnership.

Engine available in about 3 weeks due to my travel schedule. Price is for pickup in SOCAL, but can be shipped at buyer’s expense.


why do they polish the carb?

In theory it reduces turbulence and increases flow. In reality it’s probably akin to a paint protection program or extended warranty that a car dealership may sell to you, i.e. it makes them more money :laughing:. That said, I am currently using a polished carb. Some race teams I know use the polished one, while others use the standard one.

Anyone interested in a KZ should jump on this motor. Great price, and Andy has detailed his maintenance process in various posts, so there should be no mistaking that the buyer is getting a great piece here.


Timing is everything. I would have already purchased it if the timing aligned with the :moneybag::money_mouth_face:

They polish to make it look better making you think its faster I doubt you would see any difference on a stop watch my opinion only

It’s debatable, I agree. I mentioned it because the top factory prep R1 engines from TM come with the polished version, which is also more expensive (I believe around $350 vs $250, from IM)

To some it’s worth it, to others it’s not as there are few opposite theories out there as to what the polishing does before the valve.
