PROJECT TTR250 FOR OVERLANDING
Permalink  
 


I worked off and on this winter to rebuild a neglected but seldom ridden TTR250 into an overlanding bike for the backroads of Montana and Idaho.

The changes:

1 street legal conversion with lights/horn/blinkers/brake lights

2. bigger wider foot pegs

3.rebuilt the forks and shock and lowered the bike 3" front and rear for more appropriate ride height for old man. more compression dampening and ported main valve in shock. I run 8 pounds of air in each fork instead of stiffer fork springs.

4. Koso carb as posted in carb section of forum. 148, 35 pilot, needle all the way down.

5.  pipe has been gutted, so I added a  YZf250 quiet insert, nice and quiet and pulls great with 67 mpg so far on backcountry test rides.

6 built a rack system and had it powder coated, pictures are main rack, but side rack for paniers bolt on when camping is part of the ride.

7 new bearings throughout.

8   Kenda  tires........325x21 front  450x 18 rear

9  barkbusters and giant loop hand guards

10 off with stock odometer...........just using my gps for now, looking for a real speedo and odometer that uses sensors not cable.

11.  smaller led tail light,  ok but not great led head light.........still looking

12. added screened ports for more air flow in air filter box

13   13 / 44 gearing for overlanding.........so far, love it, just right for mountain roads, even nasty mud and paddling through snow, and quiet and smooth on 60 mph runs on pavement.

Very good , Michael, the work you've done has made a nice looking machine.

The carburettor substitute leaves more room around it for any adjustments - which the original lacks. no

Why are you posting here when you have all Montana for a playground? confuse  biggrinbiggrin

posting here to sympathetic audience, my friends and neighbors think I'm crazy to ride off on an old bike, they think I should be on my KTM or go buy a new beamer.  No,   part of the fun is going out of sight and phone service on something only you are respondsible for. Any problems are my fault, I like that.

I have run across post about seat improvement.  So far I have been on 100 mile day trips working out the kinks and making adjustments etc.

 

one last thing,    seat could be more comfortable.  Suggestions for a source for seat foam.  Covers abound, but I have yet to run across seat foam replacement.

 Having the confidence to know that you (or someone else) can easily fix the bike in the back of beyond, not reliant on expensive parts is essential- that's where the true adventure lies!

A well maintained ttr and a few tools and I only seem to use the tools on other bikes 

Always feel safe heading out where ever I choose
