It's a cool but complex arrangement. 8)

I got home from work early enough to run The Dirt Rat 2. I think I'm gonna like this bike. It appears my exhaust repair is solid.

I found a good deal on some new reproduction plastic. I ordered a can of correct Honda Flash Red paint for the frame, and a new blue (the correct color) seat cover. I already have some black semigloss engine paint, and silver wheel/rim paint to use on the swingarm. Add in some new decals, and an hour or two sanding and polishing the tank and this bike should look OK. :P

I know, waste of time and money, but it makes me happy and it's harmless... :wink:

The idea is a higher mixture velocity at low power which increases tractability and torque down low. This is a priority for an XR. Then to get max power at higher RPM's the secondary kicks in.

It works well but IMHO is needlesly complex. I suspect this is why Honda did away with it after only two years.

I am fortunate my bikes carburation is currently excellent and I have no intention of messing with it in any way! :wink:

That's fascinating! Thanks for the explanation, Doc.

That's hardly a waste! You'll get nothing but support from this community.

Where did you find repro plastic?

The reproduction plastic is from Maier, inc. They made good stuff, better than Acerbis IMHO. At least in terms of longevity and sunlight resistance.

The paint and reproduction decals are from a small Honda dirt bike restoration company called Flash Red Paint or something like that.

The seat cover is a reproduction from a company in Oregon I found on eBay.

Total investment on the new look will be $250 with everything, so with $450 on the bike I'm still in good shape. A restored strong running XR for $750 or so ain't bad.

Then I need to fix the lights and a new speedometer cable and enjoy the ride! 8)

Weldangrind · 11-02-2011, 12:49 AM

Do you plan to dual sport this bike?

FastDoc · 11-02-2011, 11:18 AM

I don't know, probably not. It costs about $600 for a Baja Designs kit and DOT tires and paperwork... I have the KLX for that role. I see this bike more as a ride it hard and put it away wet playbike. :wink:

FastDoc · 11-06-2011, 08:22 PM

Don't forget to check the Ride Report section for some cool pics of Roger, FastDoc, and The Dirt Rat 2 out in the Juniper Dunes Winderness Area!

Some cool videos of much better riders jumping the sand dunes!

FastDoc · 11-07-2011, 12:27 AM

Check out this D/S kit....

Too good to be true?

That's the Rocky Mountain ATV/MC kit, Doc.

Did you change your mind, Doc? Planning on dual sporting this bike?

FastDoc · 11-07-2011, 10:14 AM

I located that unit for Roger and his KLX. 1/3 the cost of a Baja Designs kit, and less than a person could put one together out of used/spare parts...

Only then I got to thinking...

FastDoc · 11-07-2011, 10:19 AM

Does anyone know if this is a good kit? It does not have a headlight but both the KLX and The Dirt Rat already have headlights. Not with the golden DOT stamp but maybe thet would pass...

Weldangrind · 11-07-2011, 10:26 AM

The PITA factor makes that kit worthwhile. You'd struggle to buy all the lights, the horn, the switches and the wire for that price, and it's all figured out this way.

I picked up some cheap switches and lights, and it took considerable effort to figure out how to wire them. I still don't have the horn or the flasher. I might consider this kit.

The Polisport headlight looks reasonable, and it's a fair price: Polisport Universal DOT MMX Headlight Red 64-6915
