Launching in second gear


blanco25

Recommended Posts

the mods are in my sig. below. This weekend went to dumont and my bike ran prettty well. But it wouldn't let me take off in second gear. gearing now is 14/41 tires are 22 in 8 paddle haulers on 8 inch rim. I feel it could of been faster if i could of got 2nd gear launches to work. BUt by no means was my bike slow. it just seemed to give people a little advantage over me. I believe LC performance was out there and those bike were retarded fast up banshee hill in the 80's.

was the sand tacky ??

thats one reason i went with a 1-5 overide instead of a 2-5.

on are sand bars i ll spin coming out of the whole in 2nd... but it seems like everytime we go to little sahara it rains and the sands tacky.. so i have to do a first gear start.

 

so, it could be ur jetting or the condition of the sand.

i wasnt at a drag strip or anything but the other day i went riding and was in the sand going up hills etc and it was rainy out and tried launching in 2nd and it would get it for a couple secs then bogg. i was thinking the sand being wet and heavier and my gearing is setup wrong. stock gearing with 22 inch kenda tires

Ive had the 13/41 and it was taking away from my topend. I was out racing for halloween with 13/41 and i was racing another banshee and his top end would get me. his was ported with a 4mil crank. So i started talking with him and he had 14/43. Next outing thanksgiving saw him out there again but i had 14/41 and now i would get him everytime by like 5 bike lengths. When i first got the bike back from kevin it would do the 2nd gear launch. what tire pressure r u guys running?

It's one of two things.

 

You can't leave in second because you're not holding the throttle wide open upon launching...

 

or...

 

You can't leave in second because there isn't enough power being made for that gearing/tire setup and your weight.

 

You can either:

1. make more power

2. change gearing or tires

3. lose weight (not suggested for any other reason than to improve your scenario)

 

 

It also seems that maybe you might be confused on air pressure for paddles. More air pressure = more traction. Less air pressure = less traction. That applies only to paddles though

I could leave in 2nd with my 4mil cub 15/40 gearing. with 13pdl extreme's

 

But.. I've always done the opposite with my tire pressure compared to Travis. More pressure = more spin

 

When I first got my chassis I was runnin 4.5lbs.. and my 60ft were horrible.. 1.67 to 1.75 was spinning till half track. Droped teh pressure to 3.5lbs and My 60 got better, started seeing 1.5's droped to 2lbs and started hooking too hard to keep the front end down..
