Cut Down Scooter. SR50 engine + a few trick bits

me mate gave me his old cutdown scooter for doing abit of work, come with an old suzuki AP50 morini engine



bit of a nail but all i want is the frame.



Iv got these bits off my old TGB: 70cc A/C Malossi kit, top racing crankshaft, doppler S3R Exhaust just needs a clean.




Thats the malossi kit dry fitted without gasket



Then i went round and baught his unfinished SR50 for £120,
and this was the outcome:







More To Sooon....

 

the SR50 came with a Airsal 70cc kit, full circle crank, malossi gear up kit
im gonna use the liquid cooled system and hook a rad up sumwere

 

That looks pretty cool man looking forward to seeing it finished!

 

Cheerz mate.
iv got some serious plans,. 98cc kit, 34mm extended crank, C4 bearings, 24mm carb/big block reeds, malossi cvt/clutch/belt drive system, yasuni C16, inner rotor staror, and whatever bolt-on tuning parts the internet provides,. its gonna look phat when done. maby even try get it road legal.

need to get a job first :rant:

 

GOSH thats gonna fly. So short wheel based! must wheely like mad :L. Will the frame need welding to it to make it stronger or will it be fine?

yeah it was flying with a bog standard ap50 engine, pure wheelie machine.
ive got a bucket full of tuning bits, its gonna be leathal!

im considering welding a bar were the tank is and fitting a removable monkeybike tank would make it stronger and look good,

 

if you look at the side on view pic of it, the front wheel is all wrong and it messes up the bikes stance, basically the forks need changing because the wheel sits too far behind the forks

i turned the fork legs around and fitted the wheel and it shifted the wheel forward about 4-6" and it looks pukka :good: ,

ill post pics to show what i meen

 

Ah Nice! This looks the BOMB!

 

BEFORE: (as the forks should be)

AFTER: (forks backwards)

What do you reckon?
i might change the forks to ones with the bolts in front?

it's trailing caster,,, if you have leading caster (the wheel forward of the forks) make sure theres enough lean on them as speed wobbles could be an issue.... something thats allready a problem with short wheelbased bikes


yeah i was thinking that,
but im gonna have to wait till i ride it to figure that stuff out,
i reckon a steering damper or two should sort it out.

tankslappers are scary.. had a few too many

 

Too right im not riding it without one.
iv seen it riding with a stock suzuki ap50 engine dooing about 50mph,

the stance of the bike just ent right so im gonna change the forks.

i basically havent started it yet iv got two bikes in for fixing an need a job to fund the tuning bits, wont b long

 

How are you getting on with this? interested to see how it turns out!

 

to be honest its on the back burner for now,
iv got too much work in the pipeline to start this project properly,

i need serious cash for the high end race parts..
Shouldent Take Too Long :grin:


ITS NOT GONNA END UP SOME HALF DIESENT BODGE JOB, im takin this str8linerzZ

 

Well good luck with it man, I'll keep watching this thread.
