scooters
Hey guys I built my own harley chopper and now buying a roketa two stroke.mr-07t-50 twelve inch tires.I've heard of all the b.s about these but I've had over forty bikes and work on my own bikes so I shouldn't have a problem fixing them.I am confused about performance parts.this model looks like a bahama four stroke but its a two.where do you get parts for these cheap scooters.tired of riding without a licence so here in n.c 50cc is legal without a license.

well if you want name brands or cheap off branded stuff it out there every where some things to remember for you motor 1e40qmb,Minarelli horizontal,jog, long case, are some names it will be called, a lot of scooter havediferent names but use the same motor so dont stress the name of the scooter so much when searching parts but something you need to identify is what size you wrist pin is and variater shaft which will be important with big bore kits and any performance variator that you buy and here is a copied how to from scrappydogs
MINARELLI 2STROKE PISTON PIN SIZE DIFFERENCE , 10MM vs 12MM and variator size difference Hey MO! How the heck do I know if my Minarelli based engine has a 12mm or 10mm wrist pin, without taking it all apart first? - Confused in Chicago Our knowledge database is growing, but we know a few things. Adly's and Hammerheads are 10, so are the Italian Minarelli engines like Malaguti, Italjet, Beta, and Aprillia. The 12mm pin is found on later CDI's, chinese JOG-2T, Vento Triton. These engines are poplular in 2-stroke full size scooters and ATVs such as Malaguti, Yamati, United Motors X-Speed, Aprilla, CPI, Benelli, Vento, Eton, Adly and many more. Italian made units tend to use 10mm pins (Chinese JOG 2T clones tend to use 12mm) please measure and check before ordering. Certain brands such as CPI / United Motors / Muz older models used 10mm newer post 2004 use 12mm. All Italian made models use the 10mm such as Aprilia / Malaguti / Italjet that are Yamaha Minarelli based. Probably the most accurate, without complete disassembly, is to measure the inside diameter of your variator pulley. If it is 21mm, your wrist pin is 12mm. If it is 18mm, your wrist pin is 10mm. You can also count the number of splines on the outer variator face where it mates with the crank. The smaller 18/10mm crank has 17 splines, the larger 21/12mm crank has 15. The larger crank was originally designed for the JOG90 engine, but comes in 50cc too. Also, don't confuse your Minarelli 2stroke with the Franco Morini type two stroke found in TGB R5 Laser, Key West, 101S, the Suzuki Address, and some Italjets. These kits are also available from Scrappydogs, as they are authorized dealers for TGB products. Hope this helps. MO! Here are our Minarelli based parts link. Some links to parts but the cpi oliver city should have the same motor has your scooter if you want to look for parts under it but remember about the wrist pin you need to find out wither its 10mm or 12mm before ordering a bbk http://www.spmotostore.com/category_s/3114.htm http://www.racingplanetusa.com/index...acc1179516d452 http://www.scrappydogscooters.com/50...rformance.html

I live in n.c and can't get a license but I can ride a scoot 50cc and under.if a bbk hac 70 ccs on them I don't want it.from what I'm told there is a tag on the frame saying what model and cc you have.I will probably hold off on the bbk and get what's best for 50cc.the scoot is 184 dry and I'm 175 so I don't no what would be a good choice as far as variaters or clutch parts.I like top end but we have a lot of hills in the mountains here also

BBK is the way to go.
Other than that, a taller gear would cost and be difficult to install, but pair that with lighter rollers, and you have more top speed, while better acceleration and hill climbing. |
