Here are a few websites with some good mods and tips http://www.geocities.com/xt350pilot/ http://www.pbase.com/corky1/xt_350_project_bike
For a rear rack try http://www.cycleracks.com/ For a clarke 4 gallon gas tank try http://www.justgastanks.com/makers.php?type=1 For moose guards, protaper handle bars, bar risers, heated grips, luggage, etc try http://www.happy-trail.com/
Corky has some decent info, but nothing like what is needed, seems these XT's are getting more poplular. Saw one go on fleabay for a hair over 2500.00 2000, 2000 miles, it was a nice specimen. Oh, this was just a day or two ago. I can help out a bit, I have wrenched enough on mine to help others out. For a good daigram and part numbers, start here http://www.xtremepowersports.com/OEM_Parts/oem_parts.html Mine. '99 all stcok, runs like a champ and 8300 miles
Thats what I figured... the xt225 stuff doesnt work on ours huh? Anyone know how to make the thing easier to kick start? Mine is an absolute bear to start. Maybe its just me, maybe it will just take time to get used to its quirks. But it also seems like it is lacking fuel when cruising at about 4k rpm. Im gonna pull the spark plug tonight and see what the crystal ball tells me. Anyone know if the electrical system can handle heated grips? Anyone know how to re-wrap the generator to put out more watts? Is the thing I read true, does the xt350 generator put out around 28v and/or cause problems with the electrical system?
Is it normal for the headlight to flash with the turn signal? It seems like its because of lack of watts or something?
Ahhhh, my first DS, first thumper, first....bike! Mine was a '94 and I put 5000 trouble-free miles on 'er. My experience with the charging system was that it was anemic. The headlight would dim at idle. And starting could be a real bear. Surprisingly, it was most finicky when it was warm (not hot). It needed just the right amount of choke or else I would kick start myself into exhaustion. Still....good memories.
Plugs Airbox and Clean the carb (use ALOT of SeaFoam) BTW, anyone got a SuperTrapp or similar they wanna sell?
Found a few more good resources, http://www.imbris.net/%7Etoadie/ Roberts XT350 site http://www.imbris.net/%7Etoadie/XT350mods.htm Has links to download shop manuals (clymer manual)and parts lists, as well as other usful carb, chain, sproket, etc info http://xt350.ve7lyd.com/ Edit 12-9-08: those links above are broken.... I have a full electronic copy of the clymer manual if anyone wants one, shoot me a PM.
so does anyone know if the electrical system can handle heated grips? They would be soooo nice in a month or two
The XT350 is a nice bike but the DR is better. Better suspension, better power, later models came with e-start, more aftermarket support....
I just bought my XT350 today. It is really fun. I have never rode any other bikes, but the 350 is just fun. I have not had it much out of 2nd gear on my farm but it has alot of power. Heres a pic.
The headlight will always dim at idle because it's run directly off the magneto on AC. If you switch to a led taillight and turnsignals, led instrument lightbulbs you might have enough Watts left over for heated grips. You could also send the stator to Ricky Stator or Baja Designs to get rewound for higher output. Make sure the auto decompression cable has 2-3mm free play at the end of the exhaust valve lever to work properly for easy starting. Off course the engine has to be tuned properly, good plug, valve clearance right, aircleaner clean and the carb jetted properly. It also helps tremendously to run synthetic oil in it. TTKlaus
YEH, a thread for us lonely/lowly XT350 riders!!! Yes, it is true, the XT350 does nothing well. No electric start, poor suspension, weak motor, no aftermarket ect! But it is a pretty good compromise for some. You can but some miles on the freeway, hit some tame singletrack, blast down some twisty blacktop all while getting 50-60mpg without hating any of it and all the while having under $2k invested and paying $125 a year for insurance. A buddy and me rode ours from San Diego to La Paz, Baja. Then hopped on the ferry for the boat ride to the Mexico mainland, docking at Matazlan (sp?). Then we rode down the Pacfic coast to a point about 125 miles south of Acapulco. From there we then headed inland and turned north to Mexico City and from there back towards San Diego along the gulf. We did this by camping almost the whole trip with only one bike related problem besides a couple of flat tires and the limited fuel range causing us few tense moments. Such as bumming some gas off of a Telephone Lineman and having the Polica tell me to siphon some gas out of the totaled Toyota pickup before they hauled it away! I will post up some minor mods I did to help it run better a little later.
Here are somethings I did to help the suspension a little...remember there isn't much you can do with out spending big bucks! Front forks...Tear down, clean, refill with a good 15wt oil and use about 330cc of oil. Stock is 10wt at 319cc. Then I run about a 2" spacer for a little more preload. To much preload and your front end will be skating around. More oil helps with bottoming, thicker oil helps with slowing down the travel (rebound to). I run the forks flush with the top triple clamp. A set of stiffer springs would make a world of difference. No air for those of you with air caps. Rear Suspension. Not much I could do there. I did move the clip on the spring to its lowest position to get a little more preload. From what I have seen on most XT's is that the clip that holds the top of the spring in place is in the middle of the three possible positions. A stiffer spring and better valving is needed here. My goal is to find a cheap TT and swap suspension.
