Greg, sorry that I haven't answered the question yet. Since I haven't had the time to look at the data needed to give you a correct answer, I thought it would be best to tell you what I would look for. Like Sandrag, I remeber a really tiny Johnson motor. Which year's kit did the big one that you are refering to come in.

First, Bduggan04 said that it was ok based on the 2002 manual. If the Johnson motor you are refering to came in 2002, then you are ok. If you want to verify it, you can get the old manuals through archive.org or search chiefdelphi, since Nate Smith has posted links to old manuals before.

If it's not mentioned in the 2002 manual, or a different Johnson motor was used in 2002, then you need to find the specs for the motor you are using. Places to look for the specs are the manual for the year it came in the kit, team updates from that year, searching chiefdelphi posts, and chiefdelphi whitepapers.

If you can't find the specs from there, you can try the manufacturer. That may be hard though.

The main thing that you are looking for is what the stall current is. If it draws more then about 20 amps when stalled, you shouldn't use it on a spike.

It is not out ofany years kit... They are Johnson 12 Volt DC motors that operate at 14000 RPM, they are brush motors. I do notr have any specks on the motors, other than that they have been used in Fp power wheels gearboxes. I believe they are the same type motors that FIRST issued us in 2K3 for the FP gearboxes. I do not believe the Amps are above 20 when stalled... They are FP motors (99.999999% sure). Can an FP be run to a spike?

Thanks,
