2006年1月19日 · my first dual sport was a 94 dr250, the power difference from the 250 to the 350 is pretty noticeable, but i had tons of fun on my 250 and when i decided i needed more power i just slapped a dr350 motor into it (direct bolt in) and had another couple years of fun on it. as a 250 it maxed out around 75 with stock gearing and as a 350 it maxed ...

2012年7月22日 · Riding the DR250 causes something of a revelation. Although the 261-pound Suzuki can't be called a featherweight, it is light compared with the Honda 250 thumper, which weighs about 20 pounds more. For the record, two-stroke MX bikes run from about 230 to 240 pounds with one gallon of gas, and Yamaha's two-stroke 11250 enduro bike weighs about ...

2019年4月30日 · So I was under the impression that the 250s all came with BST31 or TM31 carbs. The throat should be 31mm vs the 33mm of the dr350. I found the carb I pulled off a 1990 DR250S (I marked it DR250 so I would know) and the throat measure the same as my BST33 that I had on the bench (just happen to be doing some work on my carb).

2007年4月7日 · Man, you're really testing my memory here. I want to say that stock mj is 127.5 and stock pj is 37.5 (at least it was on my pumper). I believe it's the same on the CV. I'm also not sure if Suzuki jetted the DR250 carb differently than the DR350. If you have a friendly local Suzi dealer, you might check with them. So, try a 40 pj.

2020年1月18日 · Since dr250/gz250 is basically the same motor as the tu250 I went and bought a half of the motor from a tu250 with the flywheel. That motor was fuel injected from the factory and its flywheel has a 12-1 tooth pattern on it. TU250 flywheel bolted right up to my new motor and now I am back to using a stock VR sensor instead of a hall effect sensor.

2012年3月11日 · So looking at a 1987 DR250 that I have very little information on. It seems like a steal at the price listed, but didn't know how different an 87 is from a 1990 (the only year I've ever laid eyes on)? I'm having a hard time finding out info on these bikes.

2006年11月24日 · The DR250 has a great, 6spd trans which covers a wider speed range than most bikes, but even so sometimes its nice to adjust things up or down a bit. looks like this - click for bigun Note, with a 15T front sprocket you'll need a chain guide from a …

2006年10月21日 · If you've got a DR250 or 350 post up your pics and mods! Here's my recent acquisition, a 1994 DR250SE, all stock save bars, handguards and gearing. I just got it Saturday. Really like the little bike and don't intend to go crazy with mods but....a bigger, plastic tank would be nice, taller/firmer seat and perhaps stiffer suspension.

2004年2月15日 · I already have a 100% complete 1992 DR250 engine in boxes. New piston, rings, valves, etc etc. Anyone know if the 250 top end (cylinder, piston, head) will physically match up to the 350 bottom end. I know I may need to get an auto decomp cam to be able to utilize the electric start and I'll need to look closely at the compression ratio.

2013年6月12日 · DR250S's don't have BST40's. It's a BST33. The OP was describing having read the 'BST40 Bible' thread in order to gain a knowledge of the BST family of carburetors.
