IMS 4.7 vac pump

Final step now to get the last drop of gas from the wings of the 4.7 .....need some way of collecting the excess HP fuel thet sprays from this jet at the top of the HP pump.



thought I'd use the top of the water bottle. Probably wouldn't pass the scrutiny of Yamaha R&D but nobody's going to see it.



may need to raise my low level sensor to keep it out of the collector.



Vacuum pump outlet pipe cut at an angle and placed near the HP inlet where I can see the flow rate from the filler neck.

Does it work? Looking inside with the motor running at idle I see a nice pool of fuel around the base of my HP pump with excess running over the collector walls. Just what I was looking for. I need to trial this over rough riding conditions yet but on smooth surfaces/highway it works. Will run the tank dry next time out with my 2gal rotopax along.



This solves the issue for me. If your wings empty fully without all this improvising then I'm happy for you. I must say though that my bike was stationary when I observed the starvation. Could be that sloshing etc whilst underway would help feed the HP pump. Didn't try it. But going by some of the posts it seems like a few of you are not able to empty those wings.
All in all though I think the 4.7 is a great tank. So satisfying to see the bike settle on the suspension as it took on a serious helping of jungle juice. Thanks to all who had a hand in bringing it to us.

My only caution to you would be check what that bottle is made of. 90% of water and soft drink bottles are made from PET( Poly Ethylene Terephthalate), and is not 100% petrochemical(gasoline) resistant. It will degrade over a short period of time.

The idea is great, I would just make sure the bottle you use is HDPE..which is what gas cans and aftermarket tanks are usually made of.

Yes good advice thanks. I had a look in there today and half expected to see it gone but it's still there. Can't be that many types of plastics out there so I should learn about them.
Went out this evening to run the fuel down a bit more. It's not the warmest down here in the Falklands at the moment, about 04C so a good excuse to fire up the Gerbing liners and gloves. Can't help having a little smile to myself when I feel the warmth flowing through when it's so bitter outside. It just reinforces how clever this little bike is to be able to make that happen.
Been slow to mod the bike from standard. I'd screwed down the flapper and removed the AIS. Yesterday rode it with the EXUP disconnected. I'm sure it's happier pulling through the revs. Seems to me it's trying to break free from all the crap heaped upon it. It's asking for the next step to free the top end. For example in 4th I can't reach the rev limiter. It's just choked up so much. So like a lot of you folk have done I can see myself freeing up the exhaust for that top end boost. Mind you it's almost good enough for my style and for what I intend it for. But anyway, if your'e thinking of doing the EXUP but worried it will hurt bottem end I don't think it does.

Nalgene bottles would probably work for you. They are HPDE( high density poly ethylene) and you could probably find one in a similar size to the water bottle you had used.

higher, bent back handlebars?

People with longer arms than me have switched to higher bars or risers when doing more dirt/trail (standing) riding, so I went to my shop and got bars but they look pretty much like what's on there now (2008 wrr). Because there are multiple angles it's sort of hard to see minor distinctions. What do a lot of smaller people end up with for bars? My neck and shoulder are still hurting two weeks later! (smaller, and older!) Wise teachers also suggested more elbow-out posture for better (less whiskey-bush syndrome!) throttle control, so it seems more bent back handles would be good. (whiskey-bush = too much throttle, because you are leaning back and your hand is straight on the throttle so it ends up with more than you intended, and next thing, you're picking leaves and sticks out of everything)

From RichardU way back on page 474:

"Stock bars are 30.7" W, 3.8" H, 2.6" Pull Back"

Take a look at this chart and maybe you can see how different bars compare:

Holler back after you've taken a look and we'll try to help.

Icerider... great thinking on this issue!

I wonder if it might be a simpler and more worry-free fix to rig some kind of tube to channel gas from the excess fuel jet (shown in your photo) straight down into the basin the HP pump draws from.

Of course you'd still need some kind of plastic or perhaps a strip of aluminum to make the skirt around the bottom of the pump to provide a place for the fuel to pool.

I'd be afraid to use a plastic water bottle or soda bottle from here in the USA because most every time I see one that's been out in the sun awhile it's already brittle. I'm sure being continuously immersed in gasoline wouldn't extend their longevity either.

The idea of having something melt away in the fuel tank is not appealing to me at all.

So, interesting little story.

I rode with a new local buddy on a DRZ( 2007 S model) the other day. He was a very fast rider on the DRZ..faster than anyone I have ridden with on a DRZ. Not to gauge my mediocre pace, but I could not keep up with him on the ST.

Anyway, when we were heading back home on the pavement..and rolling about 40 MPH..I came up along side him and dropped a gear or two and took off....he started the same time. His DRZ 400 pulled my WRR, but not by as much as I had expected. He was only one bike length ahead( meaning my front wheel was almost even his back wheel)..when we had to slow down for a car in our lane and a pending curve.

Not sure if he has any performance mods..I have the usual FMF pipe and programmer, flapper mod, etc.

We came to the stop sign, and he even said he was surprised I kept up that close.

Just thought I'd share that.

The Safari Tank comes with a piece of sheet metal that tie wraps over the pressure relief out let of the pump. The fuel hits the sheet metal and runs down the side of the pump into the sump at the bottom of the pump to both help cool the pump when it is not submerged in fuel and prevent the fuel from spraying directly back down in to the wings. IMS said it wasn't needed when they did the 4.7 gallon tank. I recently traded my Safari for the 4.7 IMS. I made and installed the sheet metal part on the pump before putting it in the IMS Tank.

Sweet, glad to hear the little bike that can, certainly can pull it's own and then some.

2008 Yamaha WR250R for Sale - Duluth, MN



I regret to say that due to medical concerns and medical bills I must part with my beloved Yamaha WR250R. This extensively equipped, ultimate 250cc dual sport motorcycle has not been ridden much this year because of medical concerns and it’s time to face the hard reality of letting her go. The bike was purchased new from the local dealer in May of 2009 and sits now with only 2,984 miles on the clock.

It has always been adult ridden by myself only and maintained and stored inside my garage out of the elements. I’ve performed 4 oil changes on it so far and have checked and lubed the chain every 400 miles or after a really dusty trail ride. I used the Motoman break-in and it runs strong to 94 mph (indicated). I had to see how fast it would go at least once on a flat road but I’m not an aggressive rider because of health reasons and being 56 years old, so I’ve ridden it pretty easy overall and I’ve averaged 61.3 miles per gallon of only premium gas over the life of the motorcycle. It could probably use a new back tire in about 800 miles or so but the front tire is good for another 2000 miles at least. These are the original Bridgestone Trailwings that came with the bike new.

It has an extensive list of aftermarket items on it that I will either sell with the bike at a substantial loss or sell separately depending on the circumstance of the sale. I do have all the original parts as well that do go with the bike.

Here is a list of improvements, extras and some maintenance items to go with the bike and their original cost and URL’s of the websites of where I purchased these improvements and extras (most items are priced with shipping costs or they are indicated). If the links don't go directly to the item, you have the information to get to the item on the website. Some of the items have gone up in price since my purchase but I've used the price I payed for them:

Total Extras and Improvements - $2451.46


After looking at Craigslist around the country the bike would be competitively worth around $3800 stock with the mileage on the bike and the excellent condition that it is in and I do have all the original parts.

With the improvements and extras I’d like to get $1225 more (at a more than 50 percent loss in the cost of the extras) or $5025 but I’ll reasonably take $1000 more for the whole works posted which would bring the cost with extras, maintenance items and all the original parts to $4800 firm.

I think this is a very reasonable offer for a very finely equipped 2008 Yamaha WR250R with low miles that has been very well maintained and lightly ridden that is ready to take you on your adventure to go ANYWHERE.

Any questions will be promptly responded to.

Thanks in advance for your consideration.

The rider always makes the bike.

When you had your DRZ and we raced a little on the dirt roads, you were only able to pull about a bike length on me as well. More importantly, have him ride that speeds for a few miles or more. He won't be able to feel his ass or his hands from the vibes. At least I couldn't when I had one. Suzuki really needs to put in a 6th gear.

LOL..the dude actually does some serious miles on that thing. He bought it used a year ago and did some 12,000 miles...that is a lot of damn miles.

Its a shame he can't make weekend rides..you should have seen him on our normal stuff.. he's Dan fast. I know I might have dropped some speed since our Pre Irene riding..but not that much. I could not keep in in sight after the first minute of ST.

Will the Safari run almost dry? I have yet to run it down since I got it.
