Hi all newbie here, I have a Yamaha Jog RR 50cc and have recently fitted a Tecnigas exhaust....only because my old exhaust fell off and this was the cheapest 2nd hand one on ebay! anyway..when i pull off my bike seems to be really sluggish and slow and get stuck at about 25mph but if i stay on a road long enough at full throttle you hear the bike go for it then im hitting over 50mph but its taking 20-30secs at slowwww speeds to get to the point where it picks up. what can be causing this? some 1 suggested rollers to me but im a newb when it comes to bikes. any help would be great thanks Thumbs Up

Roller's will be an issue,

But also it will need be up jetted as a 2 Stroke which run's lean is very dangerous and can cause damage.

Chance's are someone on here will know what roller's you will need.

Contact Adrenaline Pedstop ( Performance scooters ) and ask them what roller's they suggest fitting to a Jog RR with " your " exhaust fitted. they will be able to tell you everything.

As for the jetting it's just a case of figuring out what main jet you need, you normally go up by 4 - 6 in jet's example if your main jet is 90 you will need to go up to 94, you do this by doing " plug chops " running the scooter up till warm, taking the bike flat out until it wont rev higher, then ignition off , grind to a holt , remove plug, then see what color it is.

Here is a color diagram...

http://motomalaya.net/blog/2011/08/10/spark-plug-colour-condition-for-carburetor-tuning-guide/

You need to be at least " good " in the picture above. ( brownish )

I am also sure if you go on the Yamaha forum you will find PLENTY of information about jetting & roller's.

Good Luck

Matt

You just need lighter rollers, I see you're coming around to the idea of rollers over jetting Matt :p

You will find them in the variator, undo the engine casing, pop it off,

You will have to read a guide on your bike to replacing them.

Alex seems to have done a lot of rollers Wink

eBay of course or adrenaline pedstop online

Make sure everything is done properly if your not sure ASK

Make sure everything is done up tight but not SO tight it brake's anything.

Follow the video and you should be fine Thumbs Up

Good Luck Thumbs Up

Yes dealer is correct however...

Running rich is ok, well it's not but it won't do your engine much harm

Running lean is BAD, if you look at your spark plug you will be able to tell.

You will need to do " Plug Chops " take the scooter on a run with the new rollers in, warm it up first, take it for a run up the road and back, which ignition off, roll to a stop, take the spark plug out and see what the color is like:

http://www.apriliaforum.com/forums/showthread.php?253881-Sparkplug-Color!

Should be brownish...

Good Luck

Matt

Be careful 1 tooth should be ok...

Take a photo of it?

If the nut is to tight you may have to give up on it for now until you find a holder, or a impact gun for the nut, if you have a compressor it's fine but chances are you will have to take it down your local mechanics garage.

That's ok, that should be fine, it's only a scooter.
