motor mount help on a pacific evolution

[BLKWIDO]

i have this bike and i wanna mount a 80cc motor on it but idk if i can due to the frame, any suggestions???

That bike?

Sorry man - that's a rack mount (behind the seat) or an electric hub motor - and that's about it...

There's just NO room, but chain-drive rack mounts can be sweet too

[BLKWIDO]

ok but im trying to watch my money, theres no way to mount it behind the seat or does it mess up the torque and stuff???

[BarelyAWake]

The "80cc" Grubee Starfires or similar? (which BTW are really only 66cc or so)

err... I'm sure McGyver could do it - but for the rest of us mere mortals it wouldn't be worth it to even try.

Yet rack mount engine kits are common and not terribly expensive and I'm sure some come in similar displacements, I haven't messed w/em in ages - dig around the forum and ask a few of the rack mount guys wassup - I'm sure they'll love to point you in the right direction!

That'd be a sweet ride w/a rack mount - lookin' forward to seein' you build it!

np man

The more I think on it - the more I suppose it could be done... build a rack with a center piece made from tubing bent to fit the mounts on the motor, or a plate mount you see some of the chopper guys with, the bottom of the drive sprocket's housing would need to be cut away so as to let the chain go down instead of back....

No.. there's got to be more probs than that lol and it's makin' my brain hurt o_O

still... one of these "80s" rack-mounted... There's gotta be someone bored enough to try it

what about this technique....




i used paint (dont have photoshop...) and i pasted this motor to size, soit would look exactly like this, what do u think???

Has been done! i have seen 1 on here... or the other place a HT rack mounted on a Road bike maybe. it was white! Tilted the other way i think it was cut around the bottom of the drive sprocket cover for the chain to come through and a different inlet manifold to keep the carb level.

I'm working on a similar build with a ladies bike the motor was kind of a hard fit to the frame,i finally got it on there with the stock mounts.This thread may help with your mounting http://motorbicycling.com/f6/notice-...unts-9582.html using simpson strong ties an muffler clamps seems like a good fit once you find the correct sizes..Good luck to you man!

no chance.


That motor in the image (if it is indeed supposed to be an "80cc" kit) is way small.

at best you'll roast your walnuts
