Hey peoples, brand new member here, first post. Not new to forums, and I get it, it gets annoying when a new guy comes in and asks the same old questions... Trouble is I have no idea what to stick in the search box to find the info I'm after, so please have patience with me. With that said I did go looking around the site last night before i signed up and did learn a thing or two. Trouble is the things I learnt just made me have more questions.
I've picked up a brand new alloy framed 29" bike, and I'm looking to stick a motor on. I also like to go really fast no matter what I'm riding. I originally looked into these bikes about 10 years ago but never pulled the trigger, but my plans from back then were a 66cc china girl with an expansion exhaust, better carb ( I remember seeing things called boost bottles back then but looking around last night i didnt even see them mentioned so i dont even know if they are a thing anymore), sick bike parts jackshaft shift kit, and then i had some real ignant ideas like putting a 5 or 10 shot of nitrous on
. I would very much like to follow my old idea almost to a T... excepting maybe the nitrous, depending on what you guys think
Now I've narrowed it down to 2 choices of motor, either this one, which is painted, which isn't any good for cooling afaik, but it seems to have a much better head design than my other option, which is unpainted.
So I guess the first question is which motor would you guys go for??
I'm kind of already leaning towards the black one just because it's cheaper and as I said it seems to have a better head design as far as cooling goes.
Now, I'm looking at gearing. I'm a big dude, 6'5", 280lbs, mostly muscular but i mean i called myself what i did for a reason
and as I said I like to go fast. I live in a kind of hilly area, no everest or anything stupid, but a few large, long inclines that I would be going up every so often.
I don't mind pedalling to get going or assist. I still plan on getting a sbp kit, eventually, but I spent almost all my hobby coin on the bike, and I've got about enough left in the piggy bank to get a motor... dammit why are stupid things like rent food and bills so expensive... Would it be worth it to me to get a smaller sprocket like a 32 tooth for all them mile an hourz
or just stick with the stocko 44tooth that comes in that black kit... The chrome/alloy/whatever kit doesnt have a tooth count that i saw. It will only be a few weeks until i pony up for the sbp kit, and probably another few weeks for it to get shipped to me here in AU, <<INSERT MOMENT OF REALIZATION HERE>> so as I write this I dont think it'd be worth the extra $20 for a small tooth. dammit. I think I answered my own question. Sometimes I have to write things down I guess. Unless someone says otherwise I think I might just throw the extra $20 back in the piggybank and get a jumpstart on the sbp kit.
Ok Now I feel like a dumbarse... the next question is would this exhaust be an appropriate expansion chamber or do I need to keep looking? I've seen better ones out there but in my searches last night I really couldnt find much in the way of better exhausts. I remember when I was looking a few years ago there were almost unlimited options on aussie ebay and all fairly cheap too - some of the 200-220$ kits even came with an expansion chamber long tube exhaust that exited near the rear hub.
As far as carby options, I honestly have no idea, I'm more of an efi kinda guy. Obviously that wont help much on a 2 stroke little banger motor so ANY suggestions you guys have would be better than what I have now which is no fking idea
Ok I've waffled on long enough and now I feel like a jackass.... Any tips/info you guys can provide me with would be muchly appreciated. or just tell me to fk off either way
