Great video Greg. I enjoyed that chill out music :-)

I was a little disappointed that i couldn't ride in to work this morning my self, we had rain then snow then 28F! So i didn't risk it and was later glad sure i didn't when i nearly crashed the car on black ice where i would normally ride the bike. :shock:

thanks, man. notice how i got cut off pretty good at 0:55? reposting to top:

i'm basically running invisible now, dressed in black, no lights, no reflectors execpt some strips on my new "Gore Bike Wear Men's Fusion GTX Gore-TexGloves":
Image
there's an inner layer and i can insert my hand on the palm side for better grip, or top side for more warmth.

they're ok, but honestly i preferred the grip of my leather army surplus gloves with a wool liner, and they mighta been warmer too, tho prolly not as waterproof.. that looked like this:

sorry for the monster images. lol

thanks to Andreym, my max e is on the way!

does the cell monitoring/balencing graph only work while charging or can the cell voltages be seen

Good luck with the lacing. I tried lacing my first motor into a 26 in rim but failed miserably and had my LBS lace it. If it isn't too late, could you make a video on how you lace your motor? :mrgreen:

laid up all day w/ a bug. nasty business and a terrible way to waste a saturday... :x

there are some great vids out there. FT's comes to mind, and i actually think pics might be better.

thanks for the wheelbuilding link. i've got a couple decisions to make on how i dish the wheel to fit in the offset dh comp triangle.

for the hs3540, i flipped the rotor, so the extruded side is on the disc side and i ran ALL spoke from the drive side to pop out the disc side:
Image
pardon the dirt. (i'll clean it up axel. :mrgreen: ) )

in the first 100 miles i had some truing to do, and you've seen how i've bashed it. but i've not touched it for a couple thousand miles (and a fire). :pancake:

but the h4080 rotor has no such extrusion, is wider, and i got half the spokes 2mm longer for the drive side.

using moonshine's pic of the JRH laced prowheel, i matched the lacing, but backwards... with my disc side to the left and his to the right. and now i'm reading the instructions about the pulled spokes - i like that better than trailing - should be inners? can't remember just now, but i'll go back.

much more valuable than my lacing for folks will be the spoke and washer measurements, which i'll post up. for MC wheels, i think his washers and, well, nipples are tight. :P

so i'm lacing ala jrh - same pattern - and gonna hope the 2mm extra spoke length will allow me to dish it enough.

once the pattern is established, it's just a matter of continuing it for each set of four all the way around:
Image
Image
i've seen others put all the spokes in first, but i don't see the point of that. they just slip out as you rotate the wheel, for me at least.

here the spoke are all very loose, attached just with one turn:

I didn't realise you could buy dished washers, have you got a link to where you bought them from?

thanks, but since it'll just get buried after tomorrow, i tried my hand at a reference guide on: 19" Motorcycle Wheels vs 26" Bicycle Wheels (rim and tires)

Good work!

I wish I knew about those $35 alum. rims before I bought mine and had to pay $90 to have them anodized. :( However I wanted to go with a 18" moto rim so I guess I did ok anyway.

Those washers are called belleville washers and come in all sizes. I think I'm going to use two per hole with one inverted in order to gain a bit of spring which should help tensioning the spokes

Thanks for the tutorial. I now know that the spokes that I ordered with the rim from HPC where too long. That would explain why I couldn't lace my motor.

no love for the last vid, huh?

the thought of me in a hotel room enough to put you off? lol

or did you see it and think the bike just looks like hell? i tried not to look, but it does look like hell. :roll:

and too fat to move or think, a bit of exercise is in order:
Image

while i take apart and play with new arrangements:
Image

that front fender is unconscionable, so i bought a set of these, inspired by bison here:
Image
i'm not in love with them, but anything will be better, huh?

and no wonder i was bottoming out. i'd never checked the rear shock air pressure since the fire (pump perished) and it was way too low:
Image
nevermind the coil rust, right? here we go. this is better:
Image

and the next step with the h4080 is to lace it up with the proper dish. quite a dish:
Image

but first i have to swap temp sensors:
Image
Image
Image

and now to wedge it under the windings:
Image

and secure/waterproof it with permatex (not using jbweld for this anymore..):
Image

and now slapping the motor together in the loose wheel, still centered, just to show the offset:

Yes, i agree, is it the manitou spv 4 or 6 ? Usually, manual, said never under100....or air can mix...remove the spring to check it, rebound full open

that is very disappointing, tho only logical. why i suspended my disbelief i can't explain, except to reason that if TOPEAK made them they should actually work!

i guess i'll just have to layer the underside with gorilla tape... :P

i do wonder if mounting it as close as possible to the tire will help. my little homemade front fender has done an amazing job of keeping the water from spraying up, and perhaps because it's so close to the hookworm that it rubs on big bumps...
full-throttle wrote:I hope the IFP didn't aerate..Can you hear air bubbles as the shock cycles?
no. i only hear wind when the shock cycles, and other bike noises... haha.

if i remove the coil, how should i cycle it? toss it back on the bike and push on the swingarm?

as far as the dh comp rear triangle offset, my rim is 2.5" wide, the frame @ the rim is 3.75", so if the gap is 1.25", then a gap of 5/8" per side would be more or less centered. so should we say the offset it 5/8"?
Image
or, since the frame is still angling in at the rim, would it be better to measure the offset further up, at the bar where the triangle ends, where the tire would rub if it were 29"?

if You will think about buying new ones, after braking those (i did with both : rear: leg , front: some kind of thin wood stick) look at those:
