Motobecane Sebring Picture

Hi All

Here is a picture of my Sebring I took tonight. This is the good side, the other side has some rust on the gas tank. I got it to run better after reading in the resources that if you don't have a air filter on the carb it might be getting to much air. I used a paper towel last night and it ran much better. Today I picked up a filter you see in the picture but it doesn't seem to be letting enough air pass so I will have to do some adjusting. I got the gas tank cleaned out by putting some small rocks in and shaking it a lot and then flushing it out with thinner. I added an inline fuel filter too. Still need to get a new back brake cable and try get the speedometer working. I saw from the picture that Zippy posted that mine is missing the covers on the side that say Sebring. I hope to fabricate something that will work for the covers, it makes the bike look even cooler.

AWESOME,Scott! Great pic! You guys see that `extendable rear rack I was telling about in another post?It will extend probably 18" rearward.Scott,you are also missing the plastic fairings over the chain and muffler sides.They are hard to find.Where do you live,Scott?Is that the single-speed Franco-Morini engine?

Re: Motobecane Sebring Picture

Also,Scott,you need to get the proper airbox for it which faces rearward with the intake holes to keep it from getting road dirt and water in it.Handy Bikes has the air box.(614-299-0550) Is the mesh filter in place? The round insert that has screens of mesh in it that fits INTO the intake end of the carb and is covered by the airbox?

Hi Don

I live in northwest Iowa. It is still 63 degrees here tonight so I got to go for another ride. It does have the mesh on the intake side of the carb but was missing the air box. I bought a filter for a motorcycle and tried it tonight but it lets to much air in so I put a piece of tin with some holes drilled in it in front of the mesh and it now runs better. I'll call handy bikes to see if I can get the right part. I'm not sure what kind of engine it is without looking closer but it has two speeds.

Re: Motobecane Sebring Picture

Dead on,Zippy! And it's THAT PRETTY even without the matching side supports and without the plastic fairings.I love `em!Got 3 Motomarina Sebrings(one bright red,two; red,white and blue).Listen,Scott! I see that engine has the forward facing intake so I'm betting it's a one-speed that sounds like a 2-speed because of the clutch spring tensioning.BUT it's a 2-speed if it has the filler plug on the right top clutch cover and the plug is also a dipstick.That would be an MO2 engine.When I got my first Sebring,I thought for sure it was a 2-speed because of the clutches grabbing so solidly and then letting the rpms come up when you hit a hill.But it was a single-speed,MO1 engine.Make sure you tell them at Handy Bikes that the intake pipe faces forward.

Re: Motobecane Sebring Picture

Yeah,Scott.I saw how pretty it was when I got up at 1:00pm(I'm on night shift this week)so I told Linda to bring Weston and follow me out to Hammertown Lake for a picnic.I was supposed to be sleeping,but I sacrificed it so we could be together on such a nice day!Who gets 8 hrs.sleep anyway?Ha! So I got a nice 15 mile ride in on my Sebring(2-speed I just installed from a Cosmo Colt)and Weston got to ride for a few miles with me.We had a great time and those devilish little turkeybugs(demonized ladybugs) were hardly present.I'll miss that sleep in a few hours.I get off at 7am.Hey,ANYTIME I get an excuse to ride a `ped instead of drive a car,I will.Especially the Super-comfortable Sebring.Enjoy it.

I'm sure it's a 2 speed. When driving down a flat road it does shift into another gear. It does have the dip stick on the right top side of the motor. Sometimes it has a hard time shifting when going up a hill but that might be normal I don't know.

Scott,

Rstricting the intake is like partially applying the choke. Make sure the insides of your carb, especially the main jet orifice are really clean. See if you can get a larger main jet to try. You obviosly have air flow to spare, if you mix the correct amount of gas with it, you will love it.

You may have to make your own, or modify a stock air box to avoid restricting it again.

Re: Motobecane Sebring Picture

Right,Scott,then it's a 2-speed.Here's how to straighten that shifting problem out.Drain the fluid from BOTH bottom plugs and refill with dexron III transmission fluid.Take it for a mile ride where you know it'll have to shift in and out several times before you get home again.You should notice quicker shifting as the crud comes loose from the components inside.If you haven't noticed it in a mile of riding,keep riding for another mile.THEN,drain the tranny fluid again and refill it with either reg.10W30 oil or Exxon Synthetic 10W30 from Auto-Zone.After that keep an eye on it for the next 100 miles or so and drain it if you see it darkening with dirt...............................ON THE JET SIZE:My 2-speed came with a number 48 jet and I installed a #52 with no problems.But I did increase the air intake box by prying out the inserts and drilling 2 more holes(1/2" diameter) in the plastic airbox.So Ron is right when he says you can probably increase the jet size.BUT make sure your exhaust port and muffler is clear of carbon.Also,I've noticed that the timing can be advanced a little for more acceleration.Just find TDC for sure.Don't trust the markings on the magneto.Use only a Bosch plug.It's the long-threaded one.Crosses with an Autolite #64.Then use a timing light to set it.That's a great bike.!
