Yeah is is definitely an engine tuning issue. I usually break in by two tanks idling on the box, then two tanks in the track extremely heavy or thick on the Hs needle to the point where the car I s just barely able to get around, aka super slow, 3rd, 4th, and 5th tank on the track I start to lean out the engine ever so slightly to get it to 180, by my 6th and 7th tank I bump it up to 200 and by my 8th I am able to tune to full bore. Shifting should start occurring on the 7th and 8th tank.

If the engine is not tuned right it will not shift well. Don`t worrie.
Tune the low and high needle untill it sounds like a dog barking with shorts bursts on the throttle:D. Snappy on the throttle and quick revving. When your done running in that is.:sneaky:

One way bearing maybe... Clean it thoroughly, clean lay shaft, add one drop of one-way lube, put on lay shaft, rotate and feel the grab.

If your oneway is over lubricated it can slip, it's engaged in 1st gear when revving up the two speed shoe, if slipping can cause changing shift or slip completely and risk a blown engine.

If 2speed shoes are asymmetric, the larger trailing mass should be greater in the direction of rotation.

If there's a silver sheen on shoe, shoe is slipping, contaminants perhaps or shoe setup.

If it's a new car then accept the entire transmission needs "running in" like an engine, chassis and bearings too, so ensure you're not binding on brakes too, anything to slow down the RPM of the two speed drum, not necssarily just the engine rpm, as your clutch can slip and the 2 Speed Drum slows down.


When stuck in 2nd gear things tend to go bad. We all cringe at a finicky 2 speed, so you're not alone.

Thank you for you insight.
Does Silver sheen on the shoe always mean slipping shoe? I've seen it even when the car runs fine.
It's not a new car so breaking in the entire drive train seems unnecessary.
I'll test it again tomorrow and update you.

Sorry I got you to misunderstand. The car was pretty fast on the track and was fast enough to shift. And the temp was around 210-220. It's just that the shifting was not consistent and sounded super weird.
I'll lean out HSN soon. 160 temperature was because I was in the process of breaking in the engine. I'll update you tomorrow.

2014 nt1
 

Anyone know when the new car will be out ? Thx

Feb end I heard. Called up Speedworld at Roseville, they accept preorders.

Were there any changes to the 14

Ive heard a revised front end

Anything more specific?

i have heard mtx5 like front end

we will see!

Hey Guys

what is the difference between 335660 and 335560 spur gears? i run the nt1 2013 and want to stock up on gears, and noticed on amain that there are two batches of various gears in the parts list

You want the 3356** gears.

These are the new graphite gears (supposed to be lighter, stronger, truer, etc.)

I ran them for 1.5 days of racing, they still look brand new.

Thanks Michael!

Does anyone have gearing ideas for winternats? Want to order a variety of pinions and spurs. And want to know if I will use stock side pulleys. JI

Nice to see you picked up the right car.:sneaky:

For the most part, you'll need 16, 17, 22, 23 pinions. The 16 and 21 come in the kit so that will save you on one. I very rarely use a 21 and I don't think you'll need it at Winternats BUT, I've never been there.

For spurs...again I primarily use 54, 59, 60. Same as before, never been to Winternats but I think you'll be fine with the 4 pinions and 3 spurs. Maybe a 53 spur also just in case you like it.
