Those cases look exactly as expected, look how the intake is pointing almost exactly at the point below where the piston would be.I'm not trying to dispute your findings, just trying to impart some knowledge onto people that want to try and get the best performance out of their engines but don't have a dyno to enable them to do trial and error testing.

OVC...yes the exhaust sucks the mixture up from the crankcase into the cylinder. However, in order for the exhaust to effectively suck the mixture out of the crankcase you have to fill the crankcase properly and the best way to fill it properly is to aim your intake at the low pressure area directly under the piston.I'm not making this up and saying it just to confuse people, it comes from ac

Jeremyo...I too though this until i did some reading.Here's the explanation: during the first part of induction (about 100+ degrees in most engines) the cylinder ports of the transfers are covered by the piston until they are uncovered by the cutouts in the piston skirt below the piston pin bosses. This has the effect of making the transfers in the early stages of induction a 'dead spac

Sorry for the slow reply, I'm in the UK so kinda been asleep.Just to let you know that's not my theory that's actually what occurs in the crankcase during induction, this was found from a lot of detailed studies. I'll try and find you one of the papers I have read on it that mentions it.In your pictures the top one would be best, I don't know how well the Dio intake aims t

Not really true, full circle crank wheels do not act as "fans" in anywhere near the way you are describing. Any theory on the spinning crank acting as a fan and dragging the charge in and around the case are outdated.In short, the (very) basic wave dynamics behind how the induction phase works are this: as the piston rises it creates a negative pressure gradient throughout the crankcase

the diameter is actually slightly smaller, i have one of both.i have notched my 3 roller and the top speed is significantly higher than with the 6 roller but like rarexo said the tuning ability of the 6 roller is much better and the variation is much much smoother.re: can the 6 roller be notched...there would be no point, the belt already rides as high as possible on the 6 roller even when stock,

i've made reeds before...just get some fibreglass and sandwich it between two bits of glass to get it nice and smooth and flat, easy. you want the good woven type of fibreglass though, not the strand matt stuff.probably better/easier to buy a sheet of carbon/fibreglass and cut some out of that though. lots of scooter websites sell sheets of it for exactly this reason

nah, i just say its running too hot. no detonation yet
noogie — 12 years ago
what on that picture is making anyone here think that is detonation?!thats just a piston thats been run for quite a long time with no cleaning and maybe a bit hot because the carbon is almost a bit white in places but it doesnt even look like its that hot. none of the tell tale signs of detonation are there.

took the liberty of hosting your photo too, hope you don't mind...just makes it easier for people to see!http://i459.photobucket.com/albums/qq313/nathan_wh_morgan/rarexosvario.jpg!

noooo way are there 30hp 50cc kits!

i know it doesn't look much like a honda camino but i imagine the electrics are pretty similar.all caminos i have seen with indicators have a battery too so you might need one.on the subject of wiring diagrams you can download a honda pa50 (same as camino) manual from the wiki on this website which will have a wiring diagram in which might help you

have you ever just tried pedaling properly?all you're doing with that vacuum is pulling the charge through to the cylinder better so its obviously gonna start easiertry pedaling quicker so that the engine actually gets a chance to pull the charge through by itself, when you just kick it like that maybe the engine isnt getting enough revs to create the suction to pull air through the carb prop

what are we supposed to be hearing in those videos? how does the sound reflect what the variator is doing at all?

i believe cappy did it first, quite a lot of info on it here in his thread:https://www.mopedarmy.com/forums/discuss/read.php?f=7&i=137512&t=133294

definitely read up on this, so many resources around on the internet but just to try and get you on the right lines......length of the pipe determines what rpm the powerband is at...angles of cone affect the "type" powerband ie. shallow tapers give a broad powerband where as steep tapers give a higher peak power but shorter powerband

find the thread "here"https://www.mopedarmy.com/forums/discuss/7/94254/94254/i did this before it was known that derbi variators fitted without modification. it would probably easier for you just to buy a derbi variator...assuming someone around here works out how to make them function properly on a pa50

eek, sorry craig. i was only speaking from my experience with boyesen reeds.
noogie — 13 years ago
i think, and i repeat think, that the boyesen reeds come in packs of two as they are designed for pyramid reed cages so you will actually only have to buy one pack.prob best to ask treats but this is the case with all the boyesen reads i've seen
