NT carb upgrade

[graydog8josh]

Im looking to get a bigger carb, but something that i can use the same jets as the NT carb. Does anyone have any recommendations? Im looking on treatland but there's so much stuff i cant figure out what will be the smoothest transistion. I just want to be able to flow more fuel and air in.

There's not really a good 'performance' upgrade for the NT carb, (unless you're on the track).
Most of the fastest bikes I've ever seen use NT carbs that have been re-jetted.

*edit*... The RT carb has a real smooth 'mid range', but the RT carb still needs to be re-jetted for a HT engine.
'Top speed' is about the same with both carbs.

ok so my question on this is since u say there is no "upgrade" carb so to say, then where can the everyday joe buy the jets for the stock nt carb?

I'm surprised no one mentioned a Speed carb. It's 2mm bigger than a NT and 1mm bigger than a RT.

I consider it an upgrade to a NT. By itself it doesn't give you any more top speed, but it has a much better idle, and should have the potential for more power. It uses the same jets as a NT. Another good thing about it is unlike a RT, it uses the same throttle cable.
I have one on all my china girls mainly because of the rock solid idle.

Speed carb...hmmm...I've seen them fire like 12$ shipped...mighty glad you told me they use the same throttle cable...buddy ordered the rse reeds and speed carb...might be next in line depending upon his findings

I swear by the NT Speed. Believe the hype...No Trouble indeed.

NT speed carb is great, except the extra fuel shut-off is prone to leakage.

i've drilled through the banjo for a straight fuel flow, removed the shut off lever and gasket, an capped it off with a homade gasket and small aluminum plate.

Baird's right; my love of the NT Speed erased my memories of the heartache she gave me early on. That damned banjo-bolt connection can really ruin your day if the gaskets get worn-out or pinched...results in an unstoppable drizzle of fuel. Mind you, I was in the middle of parting out the engine, so I was frequently removing the carb (and that banjo) for access to the rest of the engine. I ended up buying another whole NT Speed ($17 delivered offa eBay) and made sure to tighten down that bolt ONCE, and ONLY once. Haven't had a problem since. In fact, I haven't needed to use the cut-off at all.
