Thanks! Bart

Thought I'd be able to easily find this online, or in my Yamaha factory workshop manual, but: A. I can't figure out where I stashed my Yamaha factory workshop manual, and B. I can't seem to find the info online I'm looking for the diameter of the upper chromed steel tubes, not the cast...

I, too, am starting a café bike based on my 1981 Yamaha SR250. I've seen some great work here, most recently SteveG's "A Tracker named Mexico." I have a problem right off the bat that I'm sure many people who've built up an SR250 have come up against: as delivered in the late '70s - early '80s...

Thanks for the all the info! Has anyone tried the Sparx Battery Eliminator W/Capacitor? Though I'm keeping the SR-250's electric start, and thus will still need a battery, this Sparx unit looks like it may be a better choice than the original 32-year-old regulator and rectifier. Any opinions...

Can you tell me about this Kohler reg/rec mod, and what forum that's from? -- love this forum, but sometimes one needs to look around for particular technical issues.

Thanks for the replies! Anyone have experience with the Li-ion motorcycle batteries like the LiFePO4? I'm keeping the SR-250 electric starter, and I'm wondering if anyone knows what size Li-ion battery would be appropriate for a 250cc one-lunger... Thanks! Bart PS: I have MORE than all the...

This may sound like a dumb question, but consider the source. My SR-250 has a 34mm Mikuni CV carbureter, perhaps Mikuni model BS34. I'm going to get rid of the whole airbox assembly (unless someone thinks it's a good thing to keep -- I'd like to replace the regular lead-acid battery, and replace...

Re: Now You're Gonna Get It... Bobby! I think that place in hell is right next to the place reserved for those who put hardtails on modern bikes -- just my opinion, of course! Bart

Well, like most of my 53,278 projects, this one is lagging quite a bit, due to the square-puzzle-syndrome: you know those plastic puzzles with the movable-by-only-one-space-at-a-time squares? I have to: 1. Move all the junk out of my workroom, especially my 30+ complete guitars, 25 project...

Hi -- Does anyone know where I can find a Yamaha parts cross-reference list for the '80-'82 SR-250H? I'm looking at a cast/forged aluminum triple-tree from a 1980-82 Yamaha TT-250, and hoping I can replace the grotty black-painted steel stock triple-tree on the SR-250H with the TT-250 one. I...

Oh, yeah -- another question (and not the last...), I'm not familiar with the term "tracker." What's it mean? Thanks! Bart

SteveG -- those spokes look awfully long coming through the nipples -- did you have to trim them? Bart Brown

Checked out your "Mexico" build -- fantastic! I was encouraged to see many of your SR250 build inspirations are the same as mine! http://www.dotheton.com/forum/index.php?topic=38765.msg429854#msg429854 I have a couple questions (though as I'm in the US and you're in the UK, the answers may not...

I know there's another SR250 thread here, but it hasn't had any activity for over a year, so I hope no one minds if I start another. I have a 1981 Yamaha SR250 "Exciter;" everything's there, everything works. I hope forum member "wrench85" doesn't mind me borrowing his SR250 photos (and if you...
