old thread and all that - but those c clips are to keep the clutch in the right place so your belts line up and the clutch/variator housing doesnt rub against the crankcases. ive tried shims in between the housing and cases and ran without clips but it can wander a bit. ive also had it where when you tighten the 14mm centre nut the clutch locks up tightly and thats remedied by putting more shims

any updates on this project?i cant get the er2 clutch pulley to engage at less than 8500 rpm. my max power is at 8200. so ive gone back to original set up with modded leafs and heavy inner starter bits removed. im gonna try and invent my own stepped launch lever based on a mound of pube shavings

thanks for that. the water analogy explains it perfectly brian. and thanks jdc74, the little i do know about electrics is the need for good earthing and the points you covered although siting for heat dissipation is something i didnt consider.i already fitted high wattage bulbs that are dim at idle and dont blow at full pops.cheers for the help

if you cant find the right sprockets to get the gearing down just take the big ball bearings out of the variator. it wont variate and keeps it in "low gear" so im guessing a 13/54 or 13/48 non variating would top out at 35? or just find the right spacers that wont fly outwards so as to get the speed right. if thats possible, i havent tried spacing it, just ball less.in order to get i

i ve got a few av7 47mm cylinders and they really need porting and combining with a good profiled cylinder head plus a pipe and a 19mm carb to get over 55mph and towards 60mph. plus a new crank and a lightened clutch. starter arms removed. for a laugh on one cylinder i went 192 130 and it revved past 12krpm. and the vibrations disappeared after 9thou. i remember the first time i fitted one and k

interesting build, this one escaped me while i switched off and tuned a pals sp93 mobylette over winter. as for rigid exhaust ive mad a couple of pipes now and just fasten them to the bike rigidly. i weld a really over the top thick bit of steel to the pipes beely inside and that acts as the mount. i attach it to the drilled out original lower brackets for the spring. m6 is too weak ask me how i

if you read my post i tell you what electrics i am running the 12v le partie/lauter type. amd i also say its 12V bulbs i am blowing. i have a regulator with one yellow wite and a black ground. i cant fathom out how the one yellow wire takes in a feed and also lets out a feed. how can it influence the incoming and outgoing wires which could just bypass the unit ignoring it and carry on doing the b

im trying to choose the right oil seals from a bearing supplier as you cant buy off the shelf seals. but the seals they sell have all different styles R21/SC R23/TC VB and so on and its new to me.someone has had it apart before and may have fitted the wrong seals and they leak oil. plus theyve fitted a 6004 c3 bearing and im sure it should be std clearance. anyone care to point me in the right

interesting stuff.what the dyno has been invaluable in is testing the pipes ive been making.i made a doppler streetcup mod with longer length but same diameters and that gave more power earlier and peaked at 8k rpm and only 0.6hp down off the std doppler that was mismatched for my relatively low durations 176 126. i then made adjustments to the pipe but found they made it worse, each time we were

i keep blowing bulbs. ive got the le partie or lauter type electronic ignition with regulator but as i get to high revs the bulbs blow. i think the stator is rated at 12v 50 watt? i think ive got a rectifier fitted, got too many peds cant remember whats what,i had fitted 21W front and 10W rear so need to beef up a bit? electrics is not my strong point. can i fit leds that wont blow? if so what wa

ive just read you put into whichever gear is closest to 1:1 ratio and that is usually 3rd or 4th gear.

ive got a pal with a dyno. he said he usually puts bikes into third gear for dyno runs.dunno why?so should i adjust my gearing a bit lower to simulate "not in top gear" ishi usually run 13 54 but had 12 54 on for the last runive made a couple of pipes and want to try them out so should keep same gearing for best comparison but what gearing should i put on for an accurate dyno reading?has
Alan Jackson — 9 months ago
a fantastic way of finding your horsepower if you havent got a dyno, is to find someone who HAS got a dyno. 50v with av10 parmakit 82cc, low comp 135 psi , doppler streetcup pipe making it rev higher than the 176/126 low tune porting wants to. 12/54 gearing hits 62mph gps. 13 54 goes a bit faster as it pulls all the way on the level.

i might just have to do that. i did it on my paloma dasl 2 yrs ago. its not lowering it needs but moving forwards.

is there anything out there? ive found a few but there is no mention of stud spacing. i normally end up using rubber hose elbows but the silicon ones are shiny and too slippery.the polini cases come with a straight out intake and there is no room for a phbg due to engine swing.i welded up a segmented mild steel one but thats far from ideal(my tig welder wont do aluminium)

i use a nylon pulley bolted to the le partie stator with a tiny cut out. ive found the higher the bite point on the clutch the quicker the leafs wear out. i did one set in a week. then you get amazing fireworks from metal on metal. ive now settled for 4k engagement and get round that by never slowing down.

i have 4 phbg clones and only one has a hole and thats closed off with a brass ballthe others dont.i mean the two tiny holes next to the float valve. not the big holes.does yours have those tiny holes mike boyd? not the big ones.this carb runs poorly but i dont know if its due to my reed valve conversion on an av7 and 2 boost ports i cut that could be pressuring my intake and leaking chinese copy
Alan Jackson — 1 year ago
in fact ive found another cloned phbg that has one hole but its got a tiny brass ball wedged in to keep it shut.and i found another that has no holes.im guessing they shouldnt be there or the brass balls have fallen out?unless its a new development to aid float filling because they do lead to the sides of the area where the rubber tip of the float valve controls flow.

i have done.they seem to lead to an imaginary world that i hoped existed where people actually give you helpful answers. like fill them or leave them.do you not think i have looked and blown down them and sent my own pet maggot with some cotton attached so i can follow its progress?they go to the top of the needle valve. they could be there on purpose?i couldnt find a worm or maggot.i am asking be
Alan Jackson — 1 year ago
i have 2 holes either side of the float valve. are they supposed to be there? im tempted to fill them in. are they casting flaws or has a metal eating maggot or worm found its way into my float bowl?i do get an impressive amount of blowback through the carb almost like i have a hose pipe for my pilot jet. and strangely enough it runs.

thanks for that very informative reply. now you explain it i can see the disadvantave of a belt same angle as the cheeks and its reluctance to move outwards. i bought an er86 and found it was no good below 8k rpm even with weights and light springs. i fitted it to a smaller pulley to make it spin faster and it works and bites at low revs on my paloma, until it meets the power of my parmakit motor.
Alan Jackson — 1 year ago
stronger spring it is. then a launch lever.im just wondering if i can shape a belt as well, like you did. but to fit the angles ot the er3it isnt gonna hurt if there is more contact areaonly 2 or 3 mm is not logical.
Alan Jackson — 1 year ago
2 springs welded/fastened together? or 1 and a half ?my belt is slipping on the er3 cheeks. the belt seems to be too sharp an angle for the cheeks so that only the top 2 or 3 mm is in contact. i have big rubber marks on the cheeks and the belt is red hot.just tried a few test runs.belt angle by alan jackson, on Flickrif i fit too short a belt on, so the spring is under more preload there is only
