SUKUZI / PITBIKE ENGINE SWAP

[finchyn]

I currently own a Suzuki GS 125cc and im looking for a cheaper alternative option to buy a brand new larger cc engine. I have been looking on ebay at 140cc pitbike engines. I would like to know if it would fit in.

Don't be such a thick fucking prick!

Pit bike motors are generally horizontal cylinder units that are long but not very tall. No chance of fitting such an engine into a Suzuki GS125.

If your short on cash buy a brand new 150cc clone engine from a Chinese manufacturer. If your lucky it'll have the same 12bhp as the original 125cc Japanese lump.

If your too poor to buy a new clone engine, then look for a second hand GS engine, or get a manual and rebuild the engine you have already.

The best way to get a larger cc engine is to get a bike that's got a larger cc engine as standard.

I have sunk a bit of time and money into this bike, so would be nice to see it on the road again. Im just interested in putting a 250 in it or lower. just want a faster bike

[Ste]

Are you just interested in putting a bigger engine into your GS125 or are you just wanting a faster bike?

It won't be cheap or easy to wedge a 250cc engine into your GS125, it's not a straightforward way of getting a faster bike.

Cut your losses, flog the GS125 and get a bigger bike.

The DR 200 grey import bike has the best engine you'll ever get to bolt straight into a GS125. Its only about 18bhp though and you won't find one anyway.

Its the sort of thing you'd do if you had a suitable engine laying under your workbench and a broken GS engine. Otherwise Ste is right, but that's a rule of BCF anyway!

Im going to be registering it as a 125cc still, this is the problem

Actually breaking less laws.

Ignoring them and riding bike you don't have licence for, or tax or insurance, than trying to build some super-cheat, that shows 'for thought' and 'intent to deceive'.

And it is an utter work of utter criminal idiocy, when you rate risks vs rewards, when a 250 four-stroke single might only make perhaps 1 or 2 bhp more than a learner-licence allows anyway!

It's barely scraping the territory of an unrestricted two-stroke 125 single!!

Keep to simple, keep it standard, keep it reliable; and LEARN TO RIDE the effin thing.

Point to Point, I have gone just as fast and often faster on a genuinely restricted 4-stroke 125 than other folk on 600's... just had to work a bit harder to risk points on my licence in the higher speed limits. Quite a lot of fun actually, and far more rewarding doing it with genuine skill bravery and shear stupidity than, just a big engine and excess of perceived powah.... a super-cheat 125 probably wont have much of anyway!

If you have sunk a 'lot of money' into an old GS125... get the value from it; get the thing through an MOT, and go use as intended, as Learner/commuter, to get about ad get a licence.

If you want to go 'quick'. learn to ride it. Old race track adage; want a faster bike, fit a better ride! Better rider, goes faster, uses less fuel, breaks less bits, has less crashes... its all 'win'and better rider works on any bike its fitted to, not just a 125.

If you want to go really quick? Take better rider to the track! There points mean prizes, not penalties, and the ambulance is on stand-by and knows where to look for your bleeding body!!! Pubic roads are for going places, and hopefully coming back, they aren't a free for all test track!
