xt 125 r conversion to 250cc

[Prichard XT]

so iv wanted to get more power out my xt 125 r engine im still working on this

but I brought a engine last year for cheap and it was a good runner

Suzuki 250cc AC SOHC 4v twin exhaust port with carb

supposedly produces 20.1hp on the bike it came off

has a standard 3 phase stator + single timing pick up

it will need new brackets made

and electrics I have a 12v 3phase rec no cdi

sprocket alignes like its meant to swap

I have my mod 2 DAS in a couple of weeks

so questions are

would it be worth it (im keeping this bike for ever )

will I need its original cdi or would I be able to run a xt's

and has any one else done this to there xt

[Tommy xs]

good luck! I think you could pick up a similar 250 very cheap alot less hassle & without hacking your xt, just not worth the hassle to me

also definitely need suzi cdi if you do decide to try it

You'll need to change the cdi, and probably some other leccy stuff. Once you tell the insurance you will almost certainly need an Engineers report to ensure it is all done correctly, and the brakes and suspension can take it.

Lot effort for not a lot of oomf. The bike will only gain maybe 10mph and a little acceleration .

Be interesting what if though.

[Prichard XT]

well I would strip the trics out of the xt and probably use the engine on something else

engineer report is something I could possibly get from my local yam dealer im always up there and they will help me get it to standard

insurance and dvla ill defo be telling

but I guess I best get searching for the rest of the electrics then

supposedly XT stock only produces 9.?hp 20 should be fun

cheers for that

Well i remember the rs250.

Because it was hilarious watching them trying to stay with me on a 350pv and my mate on a rd125, one of the first pv bikes.

Would the 350 go in......(said quietly. Whistling innocently)

[iandouglas]

remids me of this - mz 250 doubled up to make it a 500, note these engines just hang off the centre of the t frame, no front cradle

[busyeddie]

Someone did that with a suzi x7 I think. Not very balanced I remember...

[Cynic]

There are still stories round my way of a rd400 motor in a 125 frame....

Fun times

[Prichard XT]

well the xt 660 would fit in with the petrol tank reformed and a bit of welding

yeah a 350 would

[Prichard XT]

the loom for the suzi 250 has arrived

all I need is oil change, cdi, ignition coil and make two downpipes

£200 and it will be time for me to get to work

it uses the exact same battery 1 less cost happy days
