Bike Dying, HELP!

Hey I have a 2006 Piaggio NRG Power DD LC 50

recently changed the main jet (53 to 58), put lighter rollers (4.5g), a kevlar belt and an arrow extreme exhaust. was running fine at first but now itll accelerate fine and then lose power. it wont go up hills, and on flats, itll only run at about 6500 revs and only hit about 37. when going down hill itll speed up to about 47 but struggles to get any faster. as standard it used to do 47!

i think it might be something to do with the clutch?? was thinking of ordering a new one and a 4 pack of springs to try sort it out but thought id post here first.

also, my exhaust is covered in black (oil?), dont know why its doing this either

any help would be appriciated as im pretty new to this stuff and want to get it sorted as its rinsing fuel :/

thanks in advance

 

you'll be waiting for a while before you recieve any help off here mate...

its not very active and a lot of people join up purely to ask 1 question

 

fair enough. gunna get the clutch and springs anyway

 

It's just the amount of posts iv seen unanswered and the sheer amount of people on this forum, id have thought it would have been more active that's all..

 

oh, fair doos then matey i know what you mean, i looked at the members list and the majority of them are 1 time posters . while i have a bike, ill always be here haha ..

 

Thanks for the reply
Did some research on friday and decided that 4.5g was too light, was gonna go for 5g or 5.5g rollers. With the jet, I read somewhere on the internet that it wanted to be increased by 10% when changing the exhaust so I did that, will take your advice though. gonna buy a pack of clutch springs, do some experimenting. was also thinking of buying a new contra spring because from what i read up on friday, it sounds like its too light a spring.
is there any other parts you'd reccomend for my setup? i live in wales, lots of massive hills :/
thanks again mate

 

maybe some people dont post because they dont want to just guess what s wrong ...Sometimes it is better to not say anything over saying something wrong.

You dont pretend to know stuff... you know it or you dont.

People would get things sorted much easier if they were a bit more methodical... You cannot expect to pick one jet and one set of rollers and bingo.. that s a rocket! Tuning is all about testing.

 

i know where your coming from, sometimes it does seem like that dont it

sometimes i find when i log in i see the same threads with the same replies and i start looking through old threads just to get a new read

not being negative before anyone starts im just saying get the stickers out there on them bikes get some fresh members joining

edit: you dont have to have the answers everytime, sometimes just a suggestion or a diff thought on a problem helps

 

Im looking at £50 to £70 variator speed control kits, i have no idea which one would be the right one to get though! Polini high speed variator kit, Doppler S2BR kit or the Polini speed control kit you mentioned are the ones I have my eye on, i dont know which one looks best though. if i dont end up buying one of these though, what weight contra spring do you reccomend?
Cheers again

 

The malossi multivar is a good one if you can find it (Alwasy preferes malossi over polini and I know it wasnt listed above!!! ) otherwise the polini speed control is a good piece as well.

 

i think i saw it on pedparts, will have a look

 

i put a kevlar belt on it under 500 miles ago but ill probably still go for that one, and its about a tenner cheaper than donotlink! do you know what weight rollers come with it?

 

no worries, thanks for the advice
