Drz 250

[LAPPER]

I was looking for a bike that my 15 year old son could learn to ride on . I found a 2010 Drz 250 with hardly a scratch on it - one lady owner - cheap as chips .
I was kind of thinking I could ride it on some trail rides as well if he doesn't use it and on the road occasionally .
It is a bit heavy for him but I think he will manage .

I couldn't help myself and I am now wondering how I can improve the performance enough to lift the front wheel more easily . ( its almost impossible) Mainly for logs and the like .
I downloaded a useful uncorking guide and have done some tweaks which have helped but not enough.

Ive opened the airbox slightly and cleaned up the restriction weld inside the exhaust manifold . Opened up the exhaust end cap slightly with some more holes and richened the idle mixture slightly .
Changed front sprocket from a 14 to a 13 so its 13 /42 . May get a 47 rear .
I had a 97 model which I could get the front wheel up a lot more easily from memory .
It did have a staintune exhaust but I wonder if this makes much difference

Has anyone modified one of these ?

They say in the guide to up on the pilot and main jets
Is it worth trying richer jets now it may be flowing more freely ?
I don't really like going richer - without a reason . Runs well . Plug looked ok will check again after some harder riding .

I think it suggests to from 127 to a 140 main and a 37.5 to a 40 pilot
