Longer distance riding question  By  doublert (Read 2,088 times)

Yes take the 2K contra spring out and put in the OEM one that will lower your rpms by allowing the engine to open the clutch pulley much easier with less rpms.

I put in 17/36 gears helped a bunch can cruise at 65 on the 55 mph highway and keep up with traffic at 3/4 throttle which is probably 55 GPS. I lost my license a few years back for child support and rode my modded 50cc for a bit without a license but got it all paid off and now I have a motorcycle license and insurance its awesome to be 100 percent legal.

Have you tried using slider weights ? I have Dr Pulley sliders in both of my scoots and they perform so much bettr than rollers . On my 150 I gained 5 MPH on top end and had a better acceleration curve . Sliders can push the belt out better and last longer too . Running at 6,500 you should be ok . If you get to a desired speed often you can let up off of the throttle and maintain speed with a 500 to 1000 RPM drop . You may opt for a taller gear set but will need to use lighter weights . The contra also called torque is often changed on small scoots to help when going uphill . A 150 the stock should work fine . My 150 I only replaced the factory rollers with sliders and the factory belt with a Bando at 12k miles . I am curious how it would do with 1k or 1.5k clutch springs as it already has takeoff so fast I out ran many cars on the holeshot . I do have 1.5k clutch springs , sliders , a Hoca BB torque spring base ( which keeps the spring from binding with the BBs and improves " shifts " ) on my 2T but after I go past 45 it starts to feel like under drive as I can go up a large steep hill while hitting 9k RPMs . I also plan on taller gears once my outside work takes of this spring .

I know a 50 is great for around the block and to a store nearby , but not all that for highway use . Yes a 150 even stock has enough power to get you around ( would not get on interstates as I did a few times for only a few miles at a time but it is a suicide mission ) with yours being a hot rod it should keep up with traffic without being maxed out .

In SC I have seen many 150s and few 250s with a generic moped tag instead of a MC tag like required by law . Even my 2T 50 with BBK has a MC tag since I have insurance and it goes past the 30 MPH moped speed restriction . In SC you can get a MC tag on a 50 with only a moped license with automotive license on suspension . Well mostly in the city limits of nearby places the cops have started to crack down on those with a moped tag who go faster than 30 MPH . I know a few who got pulled over and ether went to jail for no license , registration or insurance or had 1,400 in fines along with a DUS which can make your suspension get extended longer . It is not worth the risk having a daily driver which is illegal . I am not the scooter police or a rat , but I only want to tell you to be extra careful and try to stay at your states moped speed limit unless you have a safe stretch to have a lil fun . It would suck if you got pulled over and in a jam just before you are eligible to get your license reinstated .

Now a 2T with a CVT ( not so on the single speed with chain drive ) you would be surprised how even stock they run faster than a 4T . With just a few mods I have outran 3 150s , went neck with a few and had 3 other 150s outrun me on the top end . I dust them on takeoff and most at midrange but after so fast it is screaming as to needing a taller gear set . Most run 4 or 5g I run 8g and have to be light on the throttle when going downhill instead of winding it out like most can . Even bone stock it went up hill very well with me being 200 lbs . I tried to put in a 1.5k contra but I could not compress the sheave . When it was new I had a moped tag but hated how I got " Get off the road ! " and other " DUI " hate . I never have gotten a DUI or almost never drink unless its an occasion . I registered it as a motorcycle not only to get insurance but to stop the " liquor cycle BS " from ignorant cagers . So far with MC tag I have not gotten the hate but I do drive many bonkers when I take off fast or pass by them as many insist on speeding up even if I am speeding . I call it the " I am not letting a moped outrun me " syndrome . Of course it is more fun with my 150 . With a 2T you do not have to worry about the legal issues required with a 150 . A BBK is cheaper an easier to install and I have not heard of anyone locally with a 50 with BBK having the cops do a engine teardown to measure the displacement . Be very careful and remember to wear a helmet to keep you safe and have one less reason to get pulled over .

Hey Doublert,
I was not the one to ask why you are riding a 150 without a license.

Anyway answer to your question:

Taller gearing is MORE TEETH on the small number(GEAR) and LESS TEETH on the bigger number(GEAR).
So a taller gearing .. 15/37 you would go up on the number of teeth on the 15 and less teeth on the 37.

You can get the 17/37 gear set here:

And I am putting in the 18/36 gears in:
The 13/40 were the OEM gears it came with:
