Looking for suggestions on what speed kit to upgrade a stock 1977 Puch Maxi Sport High Torque? I've seen several for sale online, 60cc, 70cc, biturbo exhaust, etc. I am looking to increase speed and power for my commute to work and home. I have a pretty decent 1/4 mile hill at the end of my driveway. Thanks for any input!
dude you have a maxi... take your pick of what you want cuz most aftermarket kits are for e50s......
Thanks, it is nice to see a lot of parts available for maxis! Just looking for any personal experiences, or specific suggestions?
How fast are you looking to go, exactly? You might not have to kit it.
I have found that the Wiki is particularly helpful in learning more about the kits and pipes available for your bike and what will give you the performance you want.
yea check out the performance spreadsheet....
Maybe 30-40mph. Speed probably not as important as power for my substantial hill driveway. Where is the spreadsheet refered to? Thanks
65 metra i go up big ass hills at 40 and i am 300lbs
wow, another person from south dakota? that makes like 5!
Wow, I'm only 160lbs. so that should be plenty. Any ideas where I could buy the 65 metra kit? Does it come with a different carb and/or exhaust? Thanks
The link seems to be to a blank spreadsheet?
go to link
then click PUCH
email him he will have the kit i would put a 19 phbg carb a hicomp head and a simonini pipe but if you do all that you will wont to do the crank
You should just up your carburation and upgrade to a performance pipe. I switched to a 16 SHA Dellorto and a boss performance pipe, and i'm hitting about 37mph ~tops on my stock 75 Maxi.
Thanks, I might start with carb and exhaust. Anyone using a biturbo exhaust?
The Tecno Boss and Tecno Bullet are generally recommended over the Biturbo, I think.
just don't buy a biturbo.
if you want low end tecno circuit good.
treats should have them.
and honsetly i wouldn't kit if your looking for 30-40
just put a 16 SHA dellorto carb with that tecno circuit pipe and make sure the gearing is low. you also might want to either get a 3 shoe clutch or tune the 2 shoe thats on there right now.
Go to ebay.com, click on Community in the top right corner, type in treatshq for the store name, fill out the security thing, and click on the discount store on the right of his name. Losts of parts, and pretty good prices.
I have a biturbo, it does deliver at high revs. Get something that is a mi-lo end pipe. Or you will end up screwing with your clutch excessively for the perfect hi rpm-slip to climb hills. You should still adjust your clutch, make it land higher and make sure all the shoes pop at once, (I did this by arboring the clutch onto a bench grinder attached to a variable power source [variac], then I spun it and marked the first shoe to pop with an oily finger, until I'd always get all 3 shoes oily.) Play with your gears a bit, clutch and a pipe (then a retune) should get you to 40+, 32-35 if geared for generous torque, get a 14mm+ carb if you have a 12mm, otherwise leave it alone, just jet for the new pipe (generally an upjet).
dont mean to hog his post, but if your aiming at a cruise speed of 50, would i need a huge 80cc kit?
