problems already -_-

right heres my set up
malossi 70 kit
endy race pipe
100cc manifold
17.5mm dellorto carb
7.5 gram rollers
86 jet - 72 standard

well first off my bike doesnt idle it cuts out
its really smokey when at a stand still
takes a while to pull off
after full throttling it if you take off the revs then rev again it just bogs till it slows to 30mph then goes bk up again
and tops out at 47 mph :rtfm: :rtfm: :rtfm: :rtfm:

and secondly since ive been back on the road when my bike gets over 45 mph theres a rumbling sound coming from my transmition :rtfm: :rtfm:
any clues ???

 

is it a standard crank ? if so how many miles has the bike done ?

could be main bearings

and sounds like your jetting is too rich.. check your plug

(and please mate.. get my mudguard to me :rtfm: )

ben.

 

blud as far as i no its sent :rtfm: :rtfm: :rtfm:
fuckin mothers
il call in mornin unk:

 

bikes an 02 done maybe 20,000 kmhs

 

hmm.. does it rev high (i.e light rollers) ?

EDIT: try playing around with the mixture screw.. could be too much or not enough air coming through

ben.

 

not really :wtf:
i was told 7.5 was a lil to light for my set up tho if that counts for anything

 

imo.. too much air or too little air.. just play with the mixture screw

 

7.5 are too heavy

the pipe is too shit

the jetting will probably need a few tweaks.

 

tryed the mixture screw :rtfm:
my uncles a bike mechanic hes played round with it and it still takes like an hour to reach high revs :rtfm: :rtfm: :rtfm:

 

rollers too heavy is it takes aes to get high revs
sw1ft already said

 

oooooops imp: imp:
didnt see swifts post :rofl:

 

anyone no why top end would be so naff then ?

 

that would be the pipes fault haha

rollers could be killing top end, this is the vivacity yeh?

 

yea
the pipes a real improvement compared to standard tho unk: unk:

 

theres no post...post men are on strike!!

 

sorted the vibrations and whirling sounds unk: unk:
1. i forgot to bolt my exhaust on properly imp: imp:
2. my rollers are worn

so can anyone suggest a suitable size for my set up ?
unk: unk:

 

try different jets and play with the mixture screw i no its probably old advise but thats exactly what my nitro is doing, going to change the mixture tommorow, was working fine before its just i wanted to get the right spark plug colour

sounds like the mix is wrong

 

will do
anyone no if the carb needle could need moving
