What are the benifits/differences of running a yz125 engine instead of a DT engine?
Soz if this has been covered before or if its in the wrong section but im interested in this and would like to know
iv had 2 cr 125s on the road good fun but tempramental
mx engines are full blown race purpose buit engines and run at the limit all the time reving them sens to bits to make them move your screaming all the time
so unles you spend 200 and have a steel liner fitted to get them most out of it up to 4 bore sizes be prepaired to spend, as one little nip up on the plated barrel means £175 rebuild
the dtr engine is capable of good reliable power if tuned correctly
in my opinion id spend some ££ on the dtr engine
fit a good pipe & bigger carb then send the top end away for a fast road tune mickj abbey or some one similar
mx bikes are only built to do 15min races then rest then race then rebuild low geared and not made to be flat out for long periods most mx bikes rarely go over 60 mph
so even tho iv had both id go with the dtr lump
if u want that brutal accselleration you get with an mx bike just play with the sprockets got 12 60 t or sumet that thing will flip out ha
but ull loose top end
but like most men we never listen to some one we like to do and learn the hard way
if u wanna doit doit
only way u make your mind up on things
250 engine/500 geared right last well as u dont have to rape the engine to have fun
Its a yz125 sitting up at the farm atm, pretty sure im gonna have it off him but not sure what to do engine wise, it runs and looks good, pretty much looks the same as the dtr, its an older model 90's i think
see if the top end will graft on to the dtr bottom end, my mate had a 1987 kmx 125 and put a kx 125 top end on it using alloy base plate, went really well
found that when i was googling yz years norfe,wish it was mine tho have a sit down with a pen and paper steve. if its worth more in bits than it is restored then rip er to bits lol think i'd restore it tho,thats my teenage years right there lol

Watched a vid the other day of some chav riding YZ around town, all he did was make lots of noise and pull off quickly. Soon as he eased off the gas he looked like he was going over the handles. Better on track imo .
