I know for sure a bone stock 139qmb has top speed of about 35 to 38mph, and is rated at about 3-3.5hp @ 7-7500rpm at the crank I believe ( correct me if I'm wrong). But what about a fully modded one? For example: 52mm bbk, stroker crank, big valve head, A9 performance cam, race exhaust etc. And a top speed of about 60mph. Any inputs or if anyone has a idea, any info would be appreciated!  |

Wish I had a small engine dyno. Roy I've got a friend that pulls garden tractors and has some blueprints of a small engine dyno that they built for the garden tractors. I'm sure I could get my hands on them and its a pretty straight forward simple setup. If so Ill be more than happy to share. Happy Scootin Tony |

Millsc the stroker cranker would surely get you that extra 3mph...getr done! Lol. I gave up on that dream, so I might as well pressure someone else.

mine only went 54mph and took too long to get there. Even the slightest of inclines would keep it around 50, so I went back to stock gearing.

You have to understand a stroker crank(LONGER) will lower your rpms some, it will give you more power from the get go. But you have to worry about how many rpms you lost and now may even loose some top end speed. But now that you have the extra power you can slap in taller gears with the extra power it will be able to pull the taller gears at lower rpms.
