Okay so seems like i dodged a bullet for now i was real worried about damage to seal which seems to be fine thank god. I was Also wondering how I would solve my flywheel issues. Turned out after many more bumps in the road I ended up actually with a much faster scoot! Was working fine with the same key and same fly wheell after trying to use various methods to go without it With no success I however kept in still do hear a vibration noise which now I'm pretty sure is coming from my exhaust silencer bracket or at least something that's not important because there's a lot of rattling metal on this bike in places where things touch like the boost bottle for instance But a few days ago I wasn't so sure of that wanted to check if the key had come out again it had not but I made the same mistake while trying to in search the fly again And damaged the key beyond use I thought I would be out of a scooter for at least a few days then I thought to try a key made by top performance that I had and one of my extra minirally engines I had wanted to use Before on this Bike but for some reason thought the key didn't stick out far enough or something anyways it's a key that advances the timing or Retards timing by 3ﾟ and since my build is meant for high rebs I figured a 3ﾟ advance may not be noticeable but could definitely help I have no prior experience with advancing I had slotted a stater before but never ended up going through with it Turns out the key fit perfectly and am very shocked I haven't been using it the whole time Needless to say 3ﾟ is a world away it picks up so much faster from any engine speed I'm amazed at how much of a difference it makes definitely recommend trying it for somebody with a high revving kit and a stock Ignition  
Oh ya and i got some valve seating compound and lapped the hell out of it aswell, As it had been recommended to me by a forum member that i do this And I can't be asking you guys for advice all the time if you guys give me great advice in a don't run with it right? |

OK so here's the question I've been wanting to ask you guys for a long time I have a pipe on there that I know is limiting both the rpm as well as the fact it might not be ideal for in 86 CC I really don't have the money right now for any pipe meant for and 86 but was looking into possibly a yasuni 20-21 However they all seem to be out of stock and the only yasuni or reasonable priced pipe is on sale for 150ish i can get a yasuni r Which is a steal however I don't know if this would be much of an upgrade at all I'm sure it would be better then my current pipe a ginelli next i believe Looks almost identical to A malossi flip With a very narrow stinger looks like a pipe that could be used either on a 50 or 70 CC I'm sure this is why the engine gets hotter quicker than expected so my question is should I go for the yasuni r ? Or hold out ? Haven't been able to accomplish a top speed run and have it GPSDS when I was riding with a GPS I think I got 64 miles an hour and I was not pushing it all the way.

The next R is not in the same league as the Yasuni R. The 20-21 are very high reving pipes. www.pedparts.co.uk/blog/choosing-a-yasuni-exhaust-for-a-sports-70cc-kitI ran a C16 on my stage 6 racing, and it gave great results. Even though it might of made more power with a C20. Ideally I would save a get the right pipe. But the next R will probably frustrate you. |

Its not a technigas next r its a gianelli something The lowest great pipe made by them but it's Italian at least and much better made than a next r Although the peak rpm can't be that much higher I am still not frustrated with it specially since I got it for 40 bucks brand new without the bracket So now I'm happy because it's a solidly made pipe and will help me break it in slower then if I had a higher revving one  |

I think those gianelli's have a baffle inside, you should check. They're basically made for stock cylinders. Also for that reason I've never seen someone running it on something beyond a cast iron 70cc.
I really can't see why you are putting this exhaust on a malossi mhr cylinder. It just doesn't match. Or otherwise, why you are running that cylinder on a gianelli and stock ignition.
It's like that Roadkill Draguar episode where they put the giant Weiand blower on an otherwise stock v8. It just doesn't work...

I would disagree with your analogy I would point to brent Using His peace pipe or the non chambered one on his set up yes it is not ideal for optimal performance but you can't tell me a doesn't work to each his own, That's not me admitting that I won a more suitable pipe of course I do Sorry S this hit you the wrong way but have you dealt with piaggio pipes before? The entire header is completely different design them other minas. Can't explain it that well you will just have to look at 1 To See what I mean. I know for dam sure there is no Restriction on in the header whatsoever and none in the silencer i just found the name of pipe its a extra V2 carbon , similar in specs tp a yasuni z. And being as I live on an island where I am the only person to have a modified engine of this make let alone this type of engine. I settle for what I can get at the moment, Only other pipe that is for this engine and type that I happen to randomly have for some reason is a leo vince SP3 And we both know that I am not gonna put that pipe on it over the Extra V to IF you are aware of some restriction or that I don't know about please indulge me so I kid shop it up And Gut the son of a bitch. I lumpy happy until I have a much higher tuned pipe that has a Separate header that attaches with Springs as any pipe that doesn't have this feature Is Harder to mount seal and Use in a real world Street race set up And if I didn't mention before I was lucky enough to buy this entire block completely built including the bottom and top and and case Trenching I got it from you awesome guy off this forum for a your information The seller was also kind enough to include a stock Ignition and and gearing plus CVT components for like 75 bucks on top of so I have put into this build months of blood sweat tears and it wouldn't have even come this for if not for help from a few extremely talented friends But money wise I have put approximately a grand Not counting the frame and other components carb, radiators, pump, And other miscellaneous things that I have already had in my Possession and and you can't tell me it doesn't work because I've ridden a lot of extremely fast Scooters and I think by far this one takes the cake.

I ran a moloatsi team 77 Mina with a 100 CC chambered pipe Which was an ideal but I'd rather have more flow then less AI guess what I'm saying is I know my pipe is just a temporary toy for this cylinder And anything less than a c30 or a roost or such wont match the power band but who said all set ups have to match always? Then where would the variation be where would the Entire scooter world BS everybody That had a specific cylinder ran the exact same pipe and everything else This is a one off custom build so please don't expect it to Follow standard guidelines this is after all a mina frame with a bottom mount punk rock piaggio , with things never done before afaik and the transformation is never over until im hitting 80mph on a bike i can ride for miles of road were honda elites think they own the scene. |

You lost me after the 1st sentence, sorry. But what I am trying to say is, you are totally free to mix whatever parts you want  and that cylinder is a complete misfit in the mix.  |

Sorry Didn't mean to rant and go off on you but I see that's exactly what it looks like if you were to read any sentence of the above statement what I am most curious about is Whether or not there is some sort of internal baffle restriction or are you talking a bout a perforated inner cone on the Baffle? Im pretty sure yasuni has these aswell ? Or is ot a solid peice for noise reduction? It dont work if it's for noise .

NO high end pipes have internal baffles!They destroy the pulse waves to make a quieter more street friendly pipe..All good race pipes are hollow with smooth transitions and joints,after the outlet(stinger),the muffler can use baffles if designed correctly..With your high end cylinder,you'll need a race spec pipe for that size build,anything else will be just guessing and hoping it might work well..  |

Thanks for clearing that up. I read somewere that the contracting half or the back half of some yasuni pipes have a inner cone made of a mesh or something with plenty holes which alows them to work like a smaller chamber at lower speeds but then when the pressure builds up the waves simply pass through it.... Anyways so your saying that No matter how nice of a Exhaust I upgrade to no matter how high end it is it won't be suitable unless it's specifically for and 86CC? I have feared this might be the case the entire time however there's very few pipes and no one of them are Cheap Tailored to this size build. Is there anyway one may say well done a larger diameters stinger to allow for a better running bigger engine or anything I can do to modify A70CC pipe to make it suitable for and 86? |

I think the Yasuni R and one of the C16's have a perforated rear cone inner wrap,C20&21&30 No..Yes its possible to mod a lesser pipe to work better with your engine,give me your bore/stroke,exhaust port duration and type(triple or bridged),Max RPM and I'll run the numbers on a few well known pipes and see what can be done..

Thanks here are the specs for the durations  I was unable to find any stats for peak rpm although i know that the 77 minarelli version hits peak power at a wopping 13,500 rpm. Now i know that with the longer stroke might be lower by a bit? I also am aware these are meant to be run with a specific internal ignition but i have had goid results with stock ignitions before on my 77 mina version were i would hit approximately 12,500 rpm. I did have a better less restrictive pipe on that set up something like a koso 100cc chambered pipe. I can give you dimensions if it would be relevant. Appreciate your input. |

It looks like a Yasuni C21 would come close to an ideal pipe,,If you have any others you'd like me to check,just post them..

Thanks 190 Unfortunately all hihger end yasuni c 16-30 for piaggio Are out of stock in every site that I've searched. If anybody knows a website that still has these please let me know I would even consider a top performance 86.
Also I am searching for in up gear kit however I'm not too sure whether or not the ones I am looking at will work with my engine because I see gear covers with 16 mm and 13 mm Shaft diameters. I also see only primary gears available My block was a derbi atlantis 2002 so piaggio style any help directing me tp what gears would work would be awesome as well. I did hit 64mph on flats so im very pleased with the way it jas turned out The double radiators have seem to work in keeping it nice and cool and temps usually run about 180 is in town and wide open up a mile long Hill got me to 212 this is while a Harley tried to show me up and I was on his ass the entire way lol.
