tecumseh/doodlebug question

#1
hello, i just bought a doodlebug and want to upgrade the motor. i have a 6hp tecumseh go cart engine and want to but in the mini bike . do you know if i will need to change the sprocket and chain on the mini bike. the chain and clutch appears to be bigger on the tecumseh then the mini bike? thanks for any replies.

the newer Doodlebugs have a #35 chain so if your Tec 6HP is set up for #35, youre good.

you wont be able to use the clutch from the Baja 97cc motor, the shaft is smaller at 5/8" (i think) and the Tec at 3/4".

if the DB motor mount has 4 slots, you will have to drill new holes to fit the Tec or use an adapter plate like cjtmini sells. you will need to remove the gas tank to fit the plate and motor into the frame if you use any sort of motor mount plate, very tight fit without removing the tank.

hope this helps!
