    Doodlebug - Stretch

    Making progress on the build, slowly. Putting the engine back together & will be a mild mod build. I did the bleed for the brakes & it was better, but not great. The easy way to bleed the brakes, I hung the master cylinder on a hook up high & let the caliper dangle with the line straight &...

    Doodlebug - Stretch

    Hydraulic brake installation today, it finally arrived. They feel mushy, normal for the Tao Tao type, or should I bleed them. They engage pretty far down toward the grip now. Not like the other bike, but a different setup on the Doodle Bug. These are the Tao Tao type with 2 1/2" centers.

    Doodlebug - Stretch

    Starting on a motor build, 11:1 head work, 1st attempt at milling one, took off about 0.030" to see how it goes. Had some hand work to clean it up, but shaved & ground on a granite slab with sandpaper, then lapped it on a glass sheet with valve grinding compound. Should be OK...

    Doodlebug - Stretch

    Chopped out the engine mount & added a length of 7/8" DOM for the new motor mount at the rear of the plate. Still trying to decide on the engine & final drive system. Since Vegas doesn't sell the 460 anymore, I'm thinking about a stock 420 with a jackshaft for this one to begin with, or a torque...

    Doodlebug - Stretch

    Starting a Doodlebug build. I found a "used" Doodlebug in town for $25, so I grabbed it. Here's how it looked when I found it, a bit rough, but for the money it was a good deal. The main stuff I need is there, the rest I'll have to figure out as I go. Stripped it down & did a chop for an 8"...

    Broken spring

    It's running again, but for how long? Ran 7,300 rpm & it was pulling well. Need to run it back up to 8,000 again & see what happens. Thinking the next motor should be a larger displacement, but down-tuned from this type of build for durability.

    Broken spring

    "You must have the correct spring height for proper spring pressure on the valve seat," I got that one, but what is it? Still looking for the correct spring height for a Hemi with 26# coils. It's different than the "normal" clone head height, due to the different casting & angled valves from...

    Broken spring

    Checked pushrods (chromoly, glass & no click-click) & coil bind is non-issue. It's a good 0.06" between coils with valve fully lifted on the cam. Thinking a bad spring at this point.

    Broken spring

    I'm going to check for coil bind this morning, but it's the "Hemi kit" from ARC Racing which has the SS valves, springs & retainers as a complete set, so I need to see if there's a problem with my setup. It's a stock head on top, but ported down below. Otherwise it's basically the factory head.

    Broken spring

    Make that 7.2:1, not 72:1, sorry

    Broken spring

    No, this was the "fresh" motor with a new bottom end, new SS valves, retainers, lash caps, & the new 26# springs (SS hemi kit from ARC). It has a little over an hour total now, but has run a couple of 8,000 rpm passes prior to this one. I'd changed gearing to keep it from winding up too tight &...

    Broken spring

    Just curious, I'm running the Black Mamba cam, stock rockers (1:1 ratio) & all new SS valves, retainers, lash caps & 26 pound springs. Did a test pass today & at 6880 rpm it snapped a spring on the exhaust side. Fortunately, it didn't suck the valve & I've replaced the spring with an older one...

    VC 460 rpm range?

    After doing some more reading & looking, it seems like staying under 7,000 is the way these builds need to be done. Above this and things start to break. Below this number with a billet rod & flywheel loolks to be fairly safe for a longer running motor. Guess I need to do a bit more research...

    VC 460 rpm range?

    Wondering who has built one of these motors? Which parts, cam, insides etc. & what rpm range is "safe" for pulling good sustained power out of this type of motor?

    Balancing?

    Been running a bit more with the new bottom end, changed 1st oil & did a couple of pulls to see how it runs yesterday. Had a slight tuning issue which was resolved. Added a little more fuel in the mid range by changing the needle 2 positions richer, much better transition now to WOT. It was...
