The first closed sections can easily be bypassed by looking at a map.

I've got an urge to tie on my old route sheet holder and re-ride the route sometime in the near future just for grins.

Anyway if anyone wants copies of them holler and I'll get some printed out. I can deliver them at lunch this weekend if you want.

Naturally following a route sheet and/or using a map is an ancient art so you folks who are GPS-dependent are S. O. L.
I wont be at lunch this Sunday but would definitely love a copy of that route sheet Tim. Did John lay it out alone or was it a Stoney group effort?

Honda NX250?

I just popped onto craigslist and noticed a Honda NX250 for sale locally. Do any of you know anything about these bikes? I know nothing about them, but am interested in a smaller bike than my 650 for girlfriend or guests to use. And for my own enjoyment too...

our xt225 yami's are great bikes for girls, short guys, and tall guys who raise them up (me). They are just awesome little bikes period.

Same with suzuki DR 200's...they're surprisingly capable and stupid durable...We picked up our '05 for $1400 back ~3-4 years ago and it's a trooper for what i've put it through. I rode it for about a year at school before I picked up the DR650, and after I got hit totalling it, I realized I had more fun on the little bike and picked up a WR to replace the DR.

One of these things is a lot smaller than the others...

yes agree the dr200 is a great bike and might sit a little lower than even the 225, not sure tho.

Seat height is pretty much the same in stock form, but if you really need to drop the seat height for a super beginner, we were able to get more adjustment out of the DR than my professor's XT. The XT has a little more umph, and isn't as cold blooded as the DR, but both will fire up below 0...the DR just takes a few starts before it'll stay running that cold.

The DR has a 3.3ish gallon tank which is fantastic. I averaged ~70-75mpg with mine commuting, and the highest I got was on the first leg of the 2011 HNF ride and it squeaked out 89mpg. The tank on the XT is a gallon smaller if it matters to you at all.

The XT is a more refined bike, but the DR puts the emphasis on tractor

The plot on the right (thrust curves...and it lies...kg's are mass units not force units) are easy to make (done it for several vehicles so far) if you have a copy of the dyno :) You need the torque curve and your gear ratios/wheel size and you're golden.

The x axis is the speed which is done by multiplying engine speed by the gear ratios to find out how fast the wheel is spinning...then you multiply by the wheel circumference to get speed.

The y axis is pretty much done the same way, but you take the torque at whatever RPM and multiply it through the gear ratios, then divide by tire radius to get the thrust force.

If anyone wants i've got an excel sheet i whipped up for calculating these. You input the engine torque at various rpms, primary + secondary ratios, and tire size (metric like 90/90/21), and it spits out the thrust curves. Just shoot me a pm and i can get it emailed out to whoever wants it...although i mightaswel convert it to a googledoc tonight to make everything super easy.

I've got a matlab script too that calculates optimum shift points too from this...but not everyone has matlab.

Gotta love engineers... haven't used matlab in years, my work just doesn't let me do the fun stuff anymore.

I want a real time display to plot current instantous engine data over the reference curves while I'm riding!

I dropped my camera for the first time this week and broke the LCD screen so getting these pictures took a bit longer than I figured but for those of you who wanted to know about it here she is. The outside atleast.



It is a 2003 E250 fully extended. Full cargo, no carpet or anything. Fold out side doors and windows on the side and back. The only thing I would have asked for was cruise control. I'll find a way to add that later.



One owner, 87,000 miles and it runs fine.

Its got enough room for two bikes plus gear and it can still have a bench seat in front of that for more people. I plan on building one side up with racking that will second as a platform to sleep on and leave the other side alone to haul a bike. The rest of the van can stay empty and be used to change, hangout, hold a cooler etc and still be clean and organized. Once I figure out where everything will go i'll insulate and carpet the sides and roof and put a rubber mat down for the floor.

My goal was to keep it flexible so I can still use it as a truck but also have it be a simple RV. I can also use it as a mobile garage (damn near like I do my jeep now ) if I move for a job but don't want to buy a house and instead stay in an appartment (highly likely).

Now I just need to finish the bike so I can get to riding

Something I came across on here.

This is basically a HNF police meeting about woodsrat.
