Wanted: pitbike engine or complete bike

[yoda]

Hi chaps,
Aquired a project today- oldschool QA50 like this one:
2015

Apparently 2nd gear is a bit dodgy, so im thinking a pitbike motor is the go..

If anyone has something floating around let me know.
cheers

you might struggle with a pit bike motor i tried to put one in my zedda and it hit the front wheel A mate of mine is running his regoed Z50 with a 125cc pit bike motor, he has recently installed a 185cc big bore kit.... and he has no dramas with the tyre hitting the head, might have something to do with his choice of tyres though....

mmmm interesting when i tried to fit one in mine it fouled on the stock tyres

just had a thought i tried to sqeeze a 140cc in my zedda

Mud gaurd would get in the way with most of the bigger pitbike motors , longer forks and a gaurd that hugs the tyre more will make a 150cc zonsteen motor fit there is one here in shep punting about with the 150 stuffed into a registered Z50 on road tyres.

Same dude has a early honda 90 with 150 cc motor in it to , running spoked wide scooter rims on honda hubs with something like 140/70/14 tyres. Used to see him punting down the causeway between mooroopna and shep doing about 100.

Sounds like a 110 or 125 is the go.. Would a shot of nitrous kill them?!
Should be a fun little thing!

Should be a fun little thing!From what I understand they will handle a small shot.... Don't blame me if it blows up....;)

You can buy "Mini Nitrous kits" on the bay of E that use small bulbs similar to the whiped cream Nitrous. I wouldnt bother , I really doubt you will ever use the power out of a 125 in the frame you have asside of maybe a "Oh fuck" blat down some bitumen .

You're probably right adam.. would be overkill!

Had a great offer from Scotty, but his place is miles and miles away(Myrtleford), does anyone happen to get up that way at all?
If anyone else has/knows of anything(preferably a 110, with auto clutch) let me know!
