Hmm, If you had 2 sparks, with 2 generators, then technically you could spark double the amount of fuel, therefore increasing power substancially? Or am I just being retarded?
What about changing the springs/weights??
No, I was asking what pipe has different advantages. The pipe on the bike on my profile is bigger-diameter, and uses a 90 jet in my amal 18mm carb. my motocross style exhaust uses an 80 jet... Which would give better performance, and is there a Wiki to porting the exhaust port?
Lol, they look *SEXY*. A lot of KTM's over here have orange sprockets :]And I had to laugh at 80 tooth sprocket. I think motocross bikes only have 50 xDGood money-making idea though :D
Ok, Suzuki DR Big (4 geared bike but same principle behind tuning)Basically I've stuck a 65cc kit on, Carbon reeds, Yasuni Exhaust, 18mm Amal carburetor with #80 jet. 14f sprocket, 32r... 55mph out of it and I can't really change the gearing anymore because I wouldn't even get up the hills (I live on a mountain :S)Any more ideas?PS: I've got the exhaust from the Minicross on my
My mate used to have a really tatty Puch Minicross, But it was an 80cc for 2 years and it FLIES! He sent it off to get the crank-cases modified, new clutch springs and discs, and a 6-speed gearbox. His would power-wheelie in second gear and still hit 40mph. I'd say he could've hit 75-80 with the right gearing...
Nope, + I live in Spain xDBut they're great bikes, maybe one day I will restore it :/
I have a very similar Puch to that (a Borrasca). They're fairly quick, will do 35mph Standard. The stock gearing is quite "Motocrossy" But it is a Fun ride. They bang out 2.6 BHP and are 4-Speed manual. Quite good ride, but quite hard to get a decent rear tyre.
I run 14f and 40r, 65cc with carbon reeds. If you're too aggressive with the clutch, it wheelies. Just remember, if you're gonna wheelie, wear a lid, and not enough RPMs is fine, but too much and Woops, you're off the back.
Ok, well, how about the exhaust port? Because mine starts square, then tapers circular at the outside... is it possible to make this fully circular? And how about the problem that I described above? About it bogging down when i change gears?
Does it require disassembly of the engine to case-port it?Is this to any great advantage?
Chris- In your link, what is that thing where the air filter should be?
Doesn't that name sound, somewhat - _dirty_ - to you? Hehe :P
Ok, how much (on average) does it cost to get a bike port matched to a kit? how much extra performance does this give you?Also, when I change gears, at the beginning of revs, it seems to bog down for about a tenth of a second, then takes off. It also seems to perform slightly less after 10 minutes of riding.
Lol. I don't think it's psi. The standard Minicross has 10:1 compression, and mine has 11.5:1. Don't know if this helps but basically it has more compression than standard (but not enough to hit the cylinder head or anything). Float level is more than likely the problem. I'm thinking of slapping the 65cc reedvalve back on it and just spending loads on petrol: at least I don
Float needle is nearly new and float in good state. Float level is nearly impossible to change. Exhaust clean and cylinder with 11.5 compression. Chain in good state, sprockets as well. Ignition timing has been fiddled with, and basically it always seems to perform the same, it just depends on how easy it starts and how much the top end mis-fires :S I don't use the choke as it isn't real
Suzuki Minicross 4-Speed, the same as the one on my profile: Ok, so it's not strictly a moped but it's still a 50cc and it's not like I have gear or clutch problems...
Hmmm. Maybe I should make a list:~Fuel leaking from carburetor when non-running and on about a 10
Tomos 26f 22r *STANDARD*??Oh my god... with a 40 rear, you'd probably be off the back xDYou would probably have to custom job it, as the bolt combo of the rear sprocket probably only allows a 35 tooth...
My Ignition-Timing is a Pre-Igniting a little bit anyway :)I added a little bit of stuff back in because it was making a very... "Ping-Ping-Ping"y type of noise with no stuff :SMy bike is probably as tuned as it will ever be now, because I haven't got enough money to use the 65cc Kit on it :( I need to buy another Moped, but I'll have to get a job first xD I quite like the look
Ok, Appreciate the quick reply. Luckily I have 2 inlets, which, I believe are the same, but I might be wrong. The float level is actually nearly impossible to adjust, unless I can use something to push the needle jet higher.
Carburetor: 12mm Dellorto, no needle, just has a slide.When the bike is not running, there is fuel leaking from a hole underneath the bore, where the air filter attaches. I have checked the float level and it's fine, the float needle is in good state. The only possible problem, although it is all standard, is that the carburetor leans forwards ever so slightly (at about 10
Hmm, well, all sounds good then :)I would run the 65cc Carbon-reed kit that I have got but it's a bitch with the carburetor I've got (18mm Amal 80 Jet) and it uses up *WAY* too much petrol... I can't afford to run the bloddy thing :)
Yeah, but what I weant was what would you do to your mopeds if you had done as much as that on your bikes?
Suzuki DR Big (look at my profile pic, slightly different bike to that and with a high-rise exhaust)
Also, what performance gains would i get out of making an air filter so it face forwards??And what baffles are better, baffles with holes like an *O* or like 2 holes with the middle cut out (basically slits)??
