Flywheel mod?

[crash5]

My wife has an 01WR250 and I have an 04. The low end hit on my 04 is much smoother and easier to use. I'd like to see if I can't get her ride to match a little more closely. I think the main difference is in the flywheel weight.

Is there a flywheel weight that will work for the 01 WR250?

Will the 04WR250 flywheel weight work on the 01?

Is there something else I should try?

Thanks

I doubt it's the flywheel weight. Does her 01 have a YZF(auto decomp) cam in it?

04 wont work the flywheel is set up for electric start!!! correct me if im wrong

[crash5]

I have the wr auto decomp cam in there along with all the other typical wr mods. It starts like a dream (yeah, an 01... go figure).

I really just need to tone down the early hit. It's fun but not so much in the tight stuff where you need an easy roll on. Feels like an MX'er.

Final gearing? Go down a tooth or two?

Jetting? A JD kit?

AP adjust?

Any suggestions?

Thanks for the responses.

I'm with you. I'd like more low end and a smoother "hit" or roll on. I've heard the earlier WR's hit a little harder when you get on them. Don't know, I haven't had a chance to ride a newer 250F. I think the big bore 290 is the answer, but I'm going to try a 12T CS sproket. Some people think it's crazy, but I ride a lot of really tight technical rocky stuff and I could use a little more "throttle" control without having to resort to "clutch" control. Maybe it's just my personal style or something. ? BTW, getting your jetting completely sussed out is critical IMO.

What about one of those ergo throttle tubes with the tapered cable pull? It would allow the 'hit' to come on easier. I can't remember the company at the moment, but it did have ergo in it I believe.

Has her '01 got an aftermarket pipe on it?

Extra flywheel weight will work to mellow out the hit.

I would try an extra tooth on the front, it is the cheapest to do, but might be a bit too much. Dropping a tooth or two will do nicely, I would go two less. What gearing is on the bike?

Funny thing is, I got my missus an '05 250, I had to chase more bottom end to make it easier for her to ride! Stock '05 WR250's truely suck bigtime!

One thing is for sure, if she looks like the hit is a problem for her, change the bike set up. If she looks fine on the bike as is, don't change it at all. Does she like the power of her bike better or yours better? That would be a good guide for what you have to do.

My missus liked to ride my 450 a lot more than her 250 when her bike was stock. Not bad for a 110lb 5'10" weakling!

No bottom end and a huge hit in the mid to top was not fun for her. Power on tap is a good thing, but I know what you mean about the hit.

* Those ergo throttle tube things sound like a winner to me! Throttle control is everything.

as her '01 got an aftermarket pipe on it?

> Dubach D pipe with the quite core. Best way to smooth your power band that I know of.

Extra flywheel weight will work to mellow out the hit.

> Who has em for a wr250? I can't find one.

> The stock gearing is on there now. Are you suggesting going for more bottom end or less with this change?

* Those ergo throttle tube things sound like a winner to me! Throttle control is everything.

> Anyone know a link or a full product name on this? I can't find em anywhere but I know what yer talking about. I would think tho' that you don't want to change the way your asking for power on the bike. Just change the big snap off the bottom. I dunno.

Here ya go!

I ment to say 1 or 2 off the rear, so a 50 tooth for the rear (assuming 13/52 stock like my '05).

This will take the hit out of the bottom end a bit.

You could take out the quiet core also, this will shift a bit of the power up further in the rev range.

Does she complain about it or are you getting sick of being roosted on? ?

Hehe, no I'm not getting roosted on... not intentionally anyway

Thanks to everyone for all the responses. ?

I'm gonna try the ergo throttle tube, I think she could use a little crutch(now on order)

I'm gonna try the JD jet kit to smooth the band and make the middle bigger (now on order)

I'm gonna hold judgement on the sprocket change. I'll try it later but I'm worried about having power problems elsewhere. If I beef up the middle with the JD kit it might even out tho'

I can not find a flywheel anywhere. It seems like the right change but NOBODY has it. This makes me feel like I'm not getting something here.

I'll let you know what we see.

[gmoss357]

you won't find any FWW's for the WR. It is a nonremovable stamped piece.
