some questions on a 1996 YZ250

9 posts in this topic

I'm basically new to riding, this is the start of my second season. I purchased a 1996 yz250 last memorial weekend.

It supposedly had a upper end rebuild (including new cylinder) , I've since changed the clutch, and replaced tires ( Dunlop 756 front, Maxxis IT desert rear) , it has stock gearing (13/49) , Boysen rad valve and a Fatty pipe on it.

I rode it all last season with no problems and like the bike but now as usual with some things it just isn't fast enough. I ride mostly trails ( Lewiston /Gaylord area) , that are pretty sandy and fast (snowmobile trails) .

Are there any recommendations for this bike either to make it faster or just a better set up for the way I ride.

This is basically a 3rd sport for me ( boat and snowmobile) so dumping a ton of money into it isn't going to happen, Now if I sell my boat I'll most likely pick up a YZ450F but til then I'm stuck with the 250.

I guess I need to know what the difference between "woods" and "trail" riding is first.

We usually run snowmobile trails which have a lot of straights and sweeping corners. I'm usually in 3-5 and WFO most of the time.

Tonight I'm going to check the compression. I'm about 230lbs so I'm sure that's pretty heavy for a 250.

I've already started looking into porting, possibly big bore. But if it starts to cost too much I'll just leave it , ride it and eventually buy a thumper.

He means compression of the engine, is that what your talking about or are you talking about suspension compression, the weight comment threw me off.

As for power...you basicly covered it all in your 1st post. Porting makes a big differnce probally the best bang for buck but you will get better power from a big bore kit, kinda pricey though.

If you want to really get the most out of the '96, install a long rod kit and have PC port the cylinder. I think GYT-R sold the long rod kit. Not sure if it is still available, but I bet Eric Gorr (or the like) could set you up. A buddy of mine had this setup and it rocked! I know you said you didn't want to dump a ton of $ ,but for this bike, there is no better mod!

I just checked engine compression, it was 120lbs the manual states that is in specs , does this sound right ?

So a long rod kit and some porting sounds like what's going to have to happen.

Thanks

120 pound for a 96 isn't enough. Should be around 170 180 lbs. Did you check it with the throttle open. I had a 96 did the long rod kit and wr gears for 3 and 5th and put a 47 on. Good luck on your find.

I found a place that kind of specializes in older YZ's , here's what I decided to do.

Top end kit

shim cylinder

Head mod

flywheel weight kit , If I can find one for this year

Noleen pipe , If I can find one.

I looked into the long rod thing and really can't justify the cost at the moment, I had to draw the line somewhere.
