can anyone help

[craigvl038]

i have a vl sl 5spd and when im driving and it is under 2grand and i put my foot down it starts to back fire then it will start to go. but if i drop it back a gear its fine. it feels like the power has cut out for a second then kicks back in. has anyone had this type of problem before? could anyone help?
thanks

sounds like its almost stalling,
is ur rev gauge off because it might say 2 gs but really doing 500 rpm,
in my 5spd it really pics up after 2000rpm and b4 that its bit slugish

and wat speed ur talking bout? at bout 100 they r slugish in 5th/4th
but 4 bak firing im confussed could be ur afm is off and runing rich or lean but im just gueessing, could run a teat on it 2 c if its right

sounds to me like uve lost too much back preasure. is she idaling bad too?

[craigvl038]

it does it at like 60 in 4th and then try and put my foot down but when i drive hard i doesnt do it like when i change at about 3500-4000.
i dont think the rev gauge is off cus it acts normal.
it idles fine when im just sittin on a flat but when i just start it on a hill then the revs sit really low and she really back fires. and also some times when u go to take off softly it feels like she is gonna stall but that could mean im lettin the clutch out to soon but im not sure.

well thats y the gear ur in is to high 4 the acelration at that speed, because the gear is high it take time 2 build up revs coz of its ratio, so tahts y when u knock it bak it gose because its the right gear 4 the right job.
wat size exhaust u got? might b 2big causing negative presure and making xesive backfiring

[craigvl038]

ive got a 2 1/2 right through from extractor and a 2 1/2 to 4 inch cannon on the end.
thanks for ur help

yeah 4th gear doing 60, thats pretty steep

[craigvl038]

i just went for a drive and its anytime that your in 4th gear it back fires when i put my foot down even at 75

[VL Berlina 5speed]

hmmmm
dont use 4th

1st 0-30
2nd 30-60
3rd 60-90
4th skip
5th 90+

or if u want like i do
1st 0-60
2nd 60-130
3rd 130+
4th meh
5th wtf is that 4 (o when u bak off)

maybe guys we should stop just assuming that he is shifting to early and start suggesting some things that might be wrong with his VL so he can check them out?

Im definatly no mechanic but maybe worth checking your spark plug leads (a rat ate half way through one of mine once and it ran like a box)...

yeh get it checked out properly, until then if ur gona put ur foot down use 3rd gear, 4th is jst for cruisin...

I think people are really suggesting things that might help. does sound to me like the prob is that if you tramp it in forth, youre tryin to make the car accelerate faster then is possible at that speed in that gear. that would cause the sluggish feel, until the speed of the car starts to catch where he's tryin to put the revs... 60 in 4th is defenitely not the place for quick acceleration, if you drop it back to third an have no probs, do that, problem solved...
I know that in mine I can easily slip back into second at that speed for a quick boot, but be careful in the wet as it freaks people out when you overtake them sideways at 60/70kmph... an dont let your mates wave to them if it happens, that jus scares them even more... i should prob mention the huge potential for a crash too, jus to be responsible....
