Carbs on my VTR?

23rd January 2012, 16:47

I was looking at putting some bike carbs on my VTR, However, I've been told people normally only put them on track slags and weekend cars, due to them needing maintained. Would I be a hassle putting them on my VTR as a daily?

I'm looking into doing this on my VTR too. Just searching for some info on them.

25th January 2012, 18:11

people put them on everything nothing to do with it being specific.

However personally id not be using carbs on a car designed to run injection. Especially with the MOT

i had them on my 1600 xsi.. ran it as my daily driver for 4 years without having to touch them.....

Depends how well you set them up in the first place I suppose

I agree with Ryan, carbs on a injection car is like havig a fit mrs and making her eat cake on an hourly basis..

Esepcially when you can get a set of bodies to retain injection quite cheap these days.

as said it depends who sets them up to begin with...

you have to remember carb technology has come on a LONG way since the days of strapping some dirty ol webers or dellortos onto a mk1 escort with a pinto under the bonnet...

yamaha were using them well into the 2000`s for there R6 and R1`s.. you know the R1`s.. there FLAGSHIP superbike?? if there fuelling and reliabilty are that bad do you really think they`d still be in use????

as with so much on the net, rumours start, "my mates nextdoor neighbour used to go to the pub with a guy who`s little sister was shagging a bloke with bike carbs on his car..... it was shit" and before you know it, the whole world thinks ots a bad idea...

yes i`ll say now, it doesnt have the "perfect" driveability of a well mapped injection setup... but guess what.....

#1 - it does work
#2- you can pass MOT`s
#3- it is reliable

as long as its done right from the start...

This man speaks complete sense!!! ^^^^

Was it you that used to have a white xsi always on 106 Owners?

Bike manufacturers make some of the best carbs and throttlebodies around. Shame decent inlet manifolds are not so easy to get hold of.

Can I have more info on your setup?

26th January 2012, 18:58

providing its done to a decent standard you shouldnt have many problems

the engine was built by Shenpar

r6 carbs
dizzy
bogg bros inlet
headwork (by shenpar)
piper 285 cam
balanced + lightened bottom end
alcon paddle clutch

the carbs were initially "set" by bogg bros once running it was taken to mikeanics up in congleton for a fine tune, i think he changed the idle jets?? or needle height?? i cant really remember tbh... either way it worked...

pretty sure the vacuum was left off the dizzy, and the timing was between 8 and 12 degrees advanced @ idle

Was that a 1.6 8v xsi or the 1.4? and did you have it on a rolling road to get some figures?
cheers

Like i put in my first post.. 1600 mate..

It was rr'd @ mikeanics when he set everything up.. according to his dials it was 145bhp..

27th January 2012, 12:47

How did you find bogg bro's mate?

We have a couple of customers at work who have the bog bro's set up on there vaux's and have nothing but problems with them.

27th January 2012, 13:03

I never dealt directly with them...

Nick @ shenpar sourced the manifold and sent my carbs there for the initial "rough" setup...

You gotta remember that engine was built about 8 years ago now.. things might have changed but Nick never mentioned any problems..

27th January 2012, 13:38

Ive had bike carbs and TB's, both were setup and mapped by mikeanics on the same engine with no other mods made. The TB setup is miles ahead of the carbs in terms of driveablity, peak power/torque, sound

, realiabilty!. I never had issues with keeping the carbs in tune but there were other problems, poor starting in cold conditions and fuel serge on track.

Coming from somebody thats had both, TB's are far better. Sourcing the parts at the right price, you could do a TB conversion for the price of a carbs anyway!

27th January 2012, 13:56

Thats a bloody good figure, be interesting to know how it compared costs wise to that 157bhp throttle bodied 1600 s2 someone has on here

When you factor in the costs of inlet manifold, setting up, then something to run the spark there really is no point IMO in choosing them over an injection set up.

Years ago people were not able to get hold of thorttle body set ups cheap, ecus and mapping wasnt as cheap (with systems like predator for the saxo)

When you can have arguably better running with better drivability (esepcially when you consider our temperature sways) I fail to see why carb tuning is considered a good route to take.

I dont like the way the inlet manifold is with the bogg brothers setup. I dont like massively unequal pipe lengths, but without cutting the bulkhead panel its a bit hard to get right.
