jtr160 engine
 

hi im jonny and new to this forum
i dont do trials but ive picked up a jtr160 motor dirt cheap
its for a project im doing that involves putting the motor into a lambretta chop
frame, please dont laugh lol
i cant find much info on this motor, so far its said it could be 144cc but badged as a 200? seems odd to me to call it 160 if its not
now all i have is the bare motor without a clutch cover, cdi/coil carb or pipe.
its compact and light so thought it worth a punt and may sort my needs.
does anyone know what sort of power these thing make, and also if any other barrels fit from enduro or mx, or i can port the existing barrel and get a pipe to suit as ive got loads of room, it wont be for racing just a cheaper alternative to a 5 grand lambretta motor
any help with this motor would be much apreciated as well as a pointer to get the clutch cover from before i get the welder out and start making a cradle for engine mounts and swingarm
thanks, jonny

Where are you located.

That is an old motor probably mid-90s probably start looking on eBay for parts. Am I correct that you're going to put it in a go-kart. Trials bikes are geared very very low first second and third 4th 5th and 6th are higher but you won't get much speed out of it.

hi im in the uk
no not for a go kart, but to go in a lambretta chop frame, not sure how to post pics but google lambretta chop and yr see what i mean
if torquey enough id gear it up,
i know its old but not as old as the 60s lambretta engines that are tuned up to 50 odd hp and cost a fortune
does this motor use the same cases as the jtr 125 for example?
i can tune it, i have a 1966 vespa that has 27hp so thats not an issue

You mite want to try here some very knowledgeable people this is more a off road enduro site.

Start again.
We dynod a 250 Trials bike at 12hp circa 2000.

They are meant for Trials and totally unsuitable starting point for you purpose.

I had a 2000 200 which was a only 163cc. Was a great bike for its environment. Not so flash if trail opened up.
