More power is a concern and maintenance is starting to become a concern, I've developed back problems this year so I'd much rather pay to have something that lasts & doesn't need much tinkering.

Yeah it's oil injection so it's not like you have to pre-mix, that would be a pain. and yeah you can get 70 or 90cc BBK, and they're balls to the wall, but the reason I want a new scooter is so I don't have to screw around with it all the time. I'm not necessary concerned about the additional licensing/registration requirements of the 100+ CC b/c I already have a motorcycle endorsement and insurance... but I love how I don't have to mess with that with my 50. But I might get hassled whizzing around at 45+ MPH on a 2-stroke w/o a tag.
I'm looking at a Genuine Roughhouse, there is a gently used 50cc one for $1500 near me. "Bumper-to-bumper" warranty and roadside assistance valid thru Sept-13. A brand new one is not MUCH more but 1500 is stretching my price range and giving up one of my cars as it is...

So I've been riding my 83cc BBK scooter for a while now that riding season weather has (somewhat) returned. I've been ecstatic with the improvement in acceleration off the line but without upgrading more parts or further tuning have not seen the increase in top speed or hill climbing at/near full speed that I had hoped for. So now I'm looking at a new scooter entirely, I'm not afraid to bite the financial bullet to tag & insure a 100-150cc but how comparable would a newer 2-stroke 50cc be? I don't expect to and don't need to exceed 50 MPH but a little more punch would be perfect. Thanks for any insight!

Mine starts swaying and wobbling above 50 MPH, the engine/CVT can give me a tad more but it's scarier than 135 on my Ninja.... I keep it under 45 all the time now.

Thank you for sharing, I actually have been having a somewhat similar problem after installing a BBK and was suspecting the bendix gear... will definitely go in there and grease it up and see what happens now!

The only problems I've heard of from switching to synthetic after a long life on conventional are from it slipping through smaller gaps and causing (worse) leaks than before. But in that case there was probably bound to be a problem eventually anyways. I do still use conventional for the first ~100 miles on new engine break-in like you mentioned.

Yeah since I was just about at top engine and wheel speed, it pretty much just got shredded into a million little fibers  While I was pushing it up the hill I noticed a couple strands poking out of the vent hole. I studied the variator face today and it looks like the belt never traveled too high up to hit the bendix so I'm just going to shell out for a Bando and chalk it up to an old belt that had it's heart whaled out... |

So I finally broke my first belt today. It was on an older scooter with a fairly recent 83cc BBK installed and unknown maintenance history, so it comes as no big surprise (I was just about maxing it out at 45 MPH when it happened). Luckily it happened very close to home and it wasn't 100*F today  My question is... in what manner do belts usually break? This one virtually just disintegrated into thousands of little fibers. I am wondering if it was just because it was old and over-stressed or if I may need to look into a potential clearance problem with the bendix gear before investing in a quality replacement. Any input would be much appreciated dawgs! |

Sounds good to me. Don't know if this is a workaround / legitimate loophole but if there is a shoulder I usually go around cars to the right. I mean, they're probably going to pass me after the light anyways, why wait behind them...

I personally like Shell products, I've had great results with Rotella T6 synthetic 5W-40 in my Ninja 500 and my Tao Tao 50cc, but neither ever saw any summer riding when it was  *F or hotter. When it gets that hot... I HAVE to duck under the cover of my air conditioned Mercedes! With summer seemingly days away (we're flirting with *F again this week) I think 15W-40 is a great choice. |

I had the exact same problem on my 50cc, a valve lash adjustment cured it. It also didn't run very well cold before adjusting the valves.

In my experience with these high compression scooter engines,  octane is a must for optimal performance and MPG. It's not enough MPG boost to justify the additional cost, though. You could tune these engines for 87 octane and great MPG if that's your goal but I was all about speed. |

I would restrict the intake a tad. I think it's asking for trouble to run it that lean. Higher octane helps that condition in my opinion but only so much. On an air-cooled bike I just wouldn't risk it. My Honda Civic Hybrid had a lean-burn mode the ECM could engage at low throttle cruising on the highway and stretch the A/F as lean as 22:1!!! But that is under very precise EFI mgmt conditions and sequential ignition (two spark plugs per cylinder). If it's MPGs youre after, I think a BBK with somewhat restricted flow might be that sweet spot you've been looking for.

Hehe I'm telling you everything's a racket down there. Even fuel prices were crazy IIRC, considering the fuel tax is 30-40c less in TN than NC. If you want to see some really spectacular nature in that area, I recommend a little further north and anything on the NC side of the Appalachians. Long story short, TN got the short end of the political stick when it came to negotiating that border.
My personal favorite is Roan Mountain on the TN/NC border. Good main road access to 5500+ ft, short hikes to 6000+. Incredible panoramic views from Round Bald, the largest natural grassy bald in the world. Not to mention the largest natural rhododendron garden in the world half a mile up the other side of the mountain come mid-June bloom ;D The ecosystem diversity within such a small area is mind-blowing.
