im working on tuning my new two speed lightning and as soon as it hits second gear the bogs down and trys to stall. i know how to adjust the transmission clutch and everything but before i did i figured i would ask about this first. Thanks.

Are the RPMs winding up enough or is it shifting too fast, like almost right away on take off?

im thinking that it maybe shifting alittle late but this is my first two speed so im not sure.

well if it's shifting late in the high rpms it shouldn't be bogging down. Unless your running waaayyyy to rich on the HSP and it's bogging with fuel.

when i lean out the engine anymore than it already is it bogs down horribly and does get anywhere NEAR second gear. I dont know what it is but i am sure that its about time foe me to get another motor, this one is killing me.

I would lock it in first gear by tightening the shift adjuster screw all the way in-then tune the engine-then go back to tuning the 2 speed

now i have to fix my pull start for the thirty seventh time!

Ya might have it leaned out to much. Ya might do like codokas said and lock into first, but then I would reset it back to factory settings on the needle and start tunning over again.

What is your gearing like? What surface are you running on (grass?) If you're trying to pull a really steep gear with really big tires, it might be too much gear for the engine to pull. Nothing you can do to tune around that, unless you swap tires or clutch bell or run it on pavement.

Edit - duh, a Lightning is an on-road car. Sorry.

tylervalentine

its all good duck.

would locking it into first gear not make it run to high in the RPMs and quickly heat up the engine to fast?
It runs fine but as soon as it gets to second is when it bogs, would i not be better lowering second gear a bit than locking it?

I/ME got rid of all but one of my Redcats/Himoto's 2 speeds and replaced them with a single speed trans.And I run a small clutchbell's-13 tooth and MAN the torque and speed is awesome
