Br Jartist,
I stand corrected. Its a Keihin. Been looking and reading about so many carbs lately that I can't even keep them straight. Its a stock takeoff from a late model KLX250s
Unbelievably clean, like I said. Doesn't even look like its been run. So yeah, I am thinking starting with stock BS29 equivalent jetting (thats whats on the AVL's) plus 1 jet size.
That said, I just spent the last week tooling around southern Californina doing what I do in my other life (soundguy....working Coachella festival this time around). Took the bike across the desert....I-10 the whole way. It did wonderfully. I was absolutely the guy pissing people off in the slow lane, but still. Started like a dream. Ran strong. Blew ALLL kinds of oil out the breather. I did a little over 600 miles and used an entire quart of oil. But whatever. I'm thinking about reinstating my catch can out there by the license plate, just to stop some of the gunk getting all over everything.
(side note, i know some of you guys are running your fireballs up at speed a lot. And I know there's really no way getting around the amount of oil that will get blown out the breather at speed. What are you guys doing to keep your bikes becoming a rolling oil sheened patina?)
Now, the fun part. I have to go do the same festival this weekend. Same ride, same conditions mostly. And I am borrowing a friends KLR 650 for the trip this time. Side by side comparison. Should be fun. Because lets face it, the Enfield is a struggle at times (sans fireball, that is).
So, my parts purchasing order has been amended a bit I think.
-Chumma's oil filter kit
-I think the crank is back on the table to be done a-la Ace Engineering
-alloy barrel
-higher compression piston and retimed by one tooth cams (another thing Ace has talked about extensively)
The question is, do I do a 535 and get an Ace piston? Or do I just get a higher compression 500 piston? Price is similar (still have to do crank, barrel, and piston no matter what).....but I like fuel economy more that higher power. I was keeping a steady 65-70 mpg this past week, even running it on the highway. Will a 535 kill me in that department (noting that I am sticking with VM28 or this CV34 if I can get it working)?
Been looking long and hard at various other dual sports too. DR650, klr650, drz400. There's even a handful of smaller displacements ones I like. WR250R, DR200se, klx250s. All alphabet soup plastic machines, sure. But right tools for the job, and I think the wife might accept 2 bikes in my stable in the long run. (I don't have a car that is exclusively mine....that helps)
So yeah. I'm still continuing with this project. Think I've settled on Mefo tires and a set of Hagon shocks thats been recommended. Still waffling on the luggage situation (hard bags, soft bags, or just get an Inder and pull it to Alaska with me). Sticking with stock casquette for now, with the Radon speedo. Rewire, improved coil, blah blah blah electrics. DEFINITELY put that military front engine guard back on and put some sort of highway peg out there.
But there is for sure a more purpose built dual sport in my future as well.
Thanks all for letting me waffle on and on down here in the basement about what to do with my bike.
Be safe, get out there and ride!
