heres a pic:

^ thats the one i recently bought. same one.

i like the valve idea,  but on the ones ive used, the motion pro ones john at ec sell seem to work the best. i have another one i recently bought that seems realky good out of aborger source im testing. i have had cheap ones fail, badly, in use.  they are def not something to cheap out on. however, line pinch pliers are also a huge help, and a vacuum cap handy.  pinch one end off, cap the other. move fast and you're ok

my lightweight has them. they are fine actually

the vintage smoke rearsets dont use any of the stock linkage. so much lighter than a conventional rearset. 

I thought they were possibly compatible for some reason. i just dave f the carbs, i haven't run stock needles in forever

blue dot caliper, fzr rotor and adapters still lighter yet and work better. as far as the rear..if retaining stovk linkage i agree, cabke lighter. rearsets, depending, not always the case

well, shit.

they are pretty good about returns

doing some crossing,  i found tgis nos rack for a 63 YG1 trail master.  that, the yl1, and the campus 60 all share the same frame.  so, got it for a good price, def nos out of Japan (seyama brand).

these are fkn hensteeth for a YL1.

its dumb but the last piece. oh, last week scored an original tool kit too. check-out the wooden handle on the screwdriver

no prob.

just unground('float') that winding wire, add a wire to the end of that, and each ac lead goes to each yellow wire. then red and black are obvious .

thats what i initially ran. i later swapped it to a full wave dc rr. this one. its def a smoother signal less flickering. no battery.

i have  boot for it, the stock one fits. however it runs better w the large k&ns. they support the carbs, i made a bracket  . t500 carbs are the heaviest fucking carbs ever. eventually its getting a set of reeded cyls and 38's but i have a lot of machine work to do so its way down the road.

i still have the other carb setup in a box (sans powerjets). Just in case.

So, while I've set up carbs with existing powerjets I've never added a set to an existing setup. my 72 t500 is still running stock bodied carbs (vm32s). they are an odd vm, unique to the t500.
i had tgis set of powerjet kits (genuine mikuni) for years.  i was going to add them to the rd before i put on the tms.

the t500 had a slight carburation issue right as it hit the powerband, 4200 ish. what these are supposed to do is just add another circuit but also reduce the main size. directions state to 'reduce main by 25%, then use that number to set the power jet size'

this would set the main down to a 90, and the powerjet to a 30.

by leaning the main out this should clear up the midrange and add fuel back up top.

in theory, seemed right.  in reality, the delay of the hit was really bad. i kept up sizing the powerjet up until it was pretty decent (120). but depending what rpm you were at there was still a possible delay, and up top sustained was too rich.

so what i ended up landing on was down 2 sizes on the main,  and a 35 power jet.

this still had it safe on the main alone up to 3/4~7/8 throttle.  very crisp. i can go wide open at 2k and it just climbs right up smooth, the . the powerjet brought it the rest of the way up to the rev limiter nice and clean. 

im sure this would be different on a reed motor but like said, new to me adding one.  luckily i had a spare set of carbs to work with.

im pretty sure these interchange . however i never bought a set. https://www.ebay.com/itm/162890216371

230. yeah. was more of an engineering project.

I can say this much, its almost too light.
