hello again
its been a while, but i got some time and got as bust as i could nd there are some other interesting things that i got into the pictures will explain.
i got finishing the damper setup, i was waiting on a reamer that i could not find. so had to mod the pin a little bit. i started with a spot drill and my son and i eyeballed, it was super critical for it to be dead center . i used a smaller vise clamped in my large milling vise to hold the part, then incline the smaller vise to the 11 Deg angle the top flat was machined at, that matched the angle of the top triple mounting surface. so spot drill
then hit go through it will a drill but that was .010 inch smalle than the diameter of the pin
then go through that hole with a reamer at 50rpm with cutting oil to avoid galling the aluminum.
but that reamer was about .00012 too small and the pin would not slide in. so i grabbed he pin in the lathe and protected the pin with some paper to not scar the pin surface and use some 500 grit sandpaper and oil to slowly remove material until the pin would just slide into the hole in the anchor. in the end i removed .00011 material from the pin. so with a little grease in the hole the pin can spin smoothly with no slop in it. i added blue loctite to the base sent the bolts home for what should be the last time for a while.
i sent the damper back to scotts for a service, another reason its been a while, loctited that in place, and everything fits nicely, then of course the rest of the covers.
then it was time to address the rearset situation. i did a ton of reasearch most if not all manufacturers i was considering would not send me anykind of drawings which i guess i cant fault them for that. i wanted tho do some modeling in CAD and see which rearsets would afford the most down and forward position of the left foot. for reasons you guts are all aware of by now. but that got me nowhere fast. so i resorted to downloading pictures and resizing them to the point that attachment points were at the same positions then overlayed them on aside picture of my bike wity the rearsets on it still to see which would give my left leg the most room it needed. i tried gilles, attack, motocorse, etc etc etc and different designs from ebay and anywhere i could find them that would supposedly fit a v4 i finally decided on these knowing full well i was going to have some problems, i spotted most of the problems roght off the bat, but they were problems that i could overcome. I might get some grief for this choice but its what i had to do and if it didnt work out, not too much money so no harm no foul except for the obvious foul which im sure you guys will agree on.
you will very quickly see that these are not gilles, but they were machined so fat out of wack that they sit considerably lower and farther forward than any other i could find. so much farther forward and lower and incorrectly machined (or mistakenly sold to fit v4) that
1. the fairings hit them on both sides and had to be trimmed back or they would not refasten to the mounting points
2. the kickstand hits the bottom of the shift lever causing the shift lever to actually hang up on the kickstand
3. the kickstand will not go all the way up. so i had to drill/tap a hole for a setscrew adjuster on the flat spot to limit how far the kickstand goes up.
4. there was no where to mount the rear brake switch. so no rear brake light till i machine a bracket to hold the switch or use a brembo pressure switch
5. there is no mount for the rear brake lever return spring. so i added a spring on the lever itself on the back side that pull the lever back to rest position.
heres the right side you can see no return spring. another thing i noticed about these is that with the footrests at full forward position theres alnost no way you can get your foot under the shift lever, im not sure whats going on with that but if in need to get my left foot that far fowrard i ca machine a longer adjuster part, same for the right brake lever adjuster i have a feeling that these might be for a v2, the brake switch mount on this is of the square variety like the ones that mount on the front master cylinders, but even in the highest up position these still sit lover than the factory, right now they are at the lowest and 1 slot forward from max rear position so they will go 1.5-13/4 inches farther forward. i would like to have folding footpefs on a street bike, you never know, they do come in handy when those unexpected knockovers happen
so yesterday, i could not resist, i had a new helmet, new sena, old jacket, new gloves, i got started early in the morning prepping my left glove with the velcro treatment LOL. added the hook portion of the velcro to the left handgrip, i dug out my old arm brace and readjusted it to fit my arm. i had to change out the battery the new lithium one i had purchased, the one it had in it was junk. it would take 3-10 attempts to start the bike.. then it would sound like it as running on only two cylinders until POP the other cylinders would light off. it was strange. once the new battery was in, i cranked faster and started on the first try. and no crazy popping during warmup.
all out of excuses, i hopped online to get some insurance, printed our proof , got all ready and away we went.
first impressions. its a very responsive bike. id say a bit more than even my old race prepped R1. its very sensitive but now twitchy, it was in street mode, engine braking on high. with every nanny turned off that i could turn off or on low. expect for abs of course. they have their uses but i prefer to learn to ride it with out any of that stuff. i feel that if i can ride it well when its at its nastiest its always better...the brakes are awesome without being snatchy. torque just everywhere. no matter what gear. the riding position is aggressive but not ridiculous .. thats easy enough to get used to. i noticed little to no vibration in the bar up to 9500, i didnt get passed that rpm in any gear. i need tp work on core strength again LOL.. but theres just not enough room to let it eat..and if im being honest its been to many years since i have ridden to pretend i was just going to get on it and own it, things just dont work that way. it just started to turn into a beautiful day and figured why the hell not. and even with stick exhaust this thing sounds amazing, A V4 is not a very common sight here apparently, i saw alot of finger pointing and rubber necking LOL
so as soon as we got back i tore it apart again the check the canister and vent lines, i used a smoke tester i recently got, and nothing is clogged or restricted, but even with the canister completely out of the circuit and the vent line open to atmosphere there is not sufficient venting to stop the build of pressure when the fuel is hot. i have never had a gas cap do that and i raced in 112F ambient air temperatures. the bottom line is that the venting port for the tank is undersized or maybe has an obstruction.. once you add the canister in, the restriction goes up . then for some reason, the heat from the header there next to canister is doing something to the canister or its contents causing a complete obstruction of vapor flow
im not sure how the solenoid works in this application but we did check the solenoid and it is working.
after we returned i used the smoke tester with only air and when the whole bike is hot, the canister was so restricted that i was able to get 13 psi of air into the tank and i would hold that pressure until i disconnected the vent line from the tank to the canister, as soon as i removed the line from, the canister the pressure would start to drop..but when the tank is hot it creates so much vapor that even the vent line being open to atmosphere it can barely keep up and dump vapor fast enough to keep pressure from building. i know this has all been beat to death but has anyone looked inside the canister to see whats going on.
even thought theres a solenoid to control flow of vapors to the airbox, its still not a closed system, because theres a drain (fire hazard) on the bottom of the canister. so technically pressure should never build to point that i saw and heard when the bike was hot. i will cutting open the canister and adding drain hose to the bottom drain of the canister and teeing it back into one of the drains, i cannot believe there was no hose to drain fuel away from the headers, that is a sure way to burn a V4 down especially of theres is an overfill situation when the bike is already hot then ridden aggressively, raw fuel will get pumped into the canister , drain out the bottom and onto the header, then POOF.
so ordered some heatshield for the tank. and im gonna cut open canister to see whats going on in there that could cause a restriction with high temps.
i also discovered the previous owner remove a chain guard,, so i ordered that stuff too.
but all in all the first ride went great, its everything i remembered it to be, nothing like in the world.
