You need to open up your exhaust and change your jets to a larger size 58/158.

Go to the "Gordon Mod's" sticky at the top of the XR250/400 forum. You'll learn a lot there...

To get back on topic a bit, I compared the gearing specs on the bike.

Honda XR400R stock sprockets are usually: 15T front; 45T rear. To get the 2.466 ratio they have to use 15/37. I wondered if a 37 would fit on our hubs. I'm sure a 38 would, but dunno about any smaller.

XR400R: primary = 2.826; Trans (1->5)= 2.615 1.842 1.400 1.120 0.926

400 SM: p = 2.666 ; (1->5) 2.615 1.789 1.350 1.076 0.892

So 1st is the same and then it is a wider ratio set after that. Heck, if the XR400R had that gearset in it, it would be a better dual sport bike. ?

The primary of 2.666 (64/24) is an existing part -- they offered that crank gear and clutch basket as part of the original HRC XR400R kit introduced in 1996. The other gearsets must be as follows:

XR400R XR400-supermoto

1 34/13 34/13

2 35/19 34/19

3 28/20 27/20

4 28/25 28/26

5 25/27 25/28

Also note the lower compression ratio. Probably just a different piston (as that would be the lowest cost option). Electric start means it probably shares cases and so on with the TRX400EX motor.

I just noticed the passenger pegs on that bike. Looks like they just clamp right on the sub frame...no weld like the baja ones. I could use a set like that to give the kids something to rest their feet on when taking them for little rides. Anybody have any ideas as to where I could get somthing comparable to that setup.

Japan ? Thats the only place I have seen the clamp on style. I picked up a brochure for the XR250 while I was there. They list it there.

Probably be able to fabricate one for cheaper.
