NT and NT Speed Carbs
You will need to learn to read your spark plug and learn a bit about tuning prior to changing jets, but it's not too difficult, and changing the jet itself is straight forward. Just drain the fuel, remove the float bowl and unscrew the jet, then reassemble.
WE HAVE A GOOD SUPPLY OF THE SIZE RANGES WE CARRY
Sizes range from 0.60 to 0.84 mm. Stock size is 0.70 mm. Please use the drop down menu below to select.

Shipping was a little on the slow side but the jets worked fine noticeably increasing performance on my Flying Horse with a Sick Bike Parts HD jack shaft kit.

Ordered these on a Sunday night at 11pm. Before I woke up on Monday a.m. they were on their way with a tracking number. Received in Florida in 2 days, very fast.

Read the reviews and some forums on which jet to install, so I order the 0.66mm like most people have. I installed it on the NT Speed Carb and now my bike is running smoother and spark plugs color is perfect tan. Thanks Sick Bike Parts!

I took a chance and ordered only a .66 sized jet and seems to work perfect. I can climb this steep hill near my house in 4th gear instead of 3rd gear with the stock size jet and my plug color is a perfect tan color.

Super Fast shipping! Re-jetted my NTTC carb from .72 to .66 and it now runs perfect. These guys are great! Spark plug is dry and light chocolate color in stead of wet and black.

Thanks again to SBP! These are a little tight but DO fit Speed and NT carbs. Don't let the pic fool you the slot goes all the way across the jet surface. They are NOT exact replacements but as i said DO fit.

they are 3 bucks each so i bought 3 to make sure to get the right size

I bought a SBP expansion pipe and an air cleaner for my RAW50 with NT carb, and it worked great! Switching to Opti2 at 100:1, however, had it four stroking too much. Rolled the dice on a .68 jet, and it's exactly right. The jet is a little snug into the emulsion tube, but I don't see myself ever taking it out, so no worries there.
