Set of complete twin 1.25 inch carbs would these fit on a 998cc and how much would it improve the car? would it be noticeable or not?



Thanks

Depends what you mean by improve, personally i wouldn't bother.., i don't think it's worth the effort etc.

Apparently throttle response can 'improve' and the 'smoothness' of the engine can 'improve', to be honest i've always found it to be negligable.

Maintenance wise, there's a lot of scare mongering that goes on regarding twins, If set up carefully, using ther ight linkages and tuned properly, they are no more hassle than a single SU.

yeah i asked a mate of mine about twin carbs. he said don't because they a complet bugger to set up.

if you want some more from your carb might as well get a HIF 38 (?) probly be easyer and better.

if you use the correct linkages and balance the oils well enough so you get the same response from each carb they're fine, they're not hard to set up as such, you just need to know what you're doing.

Id second moving to a larger single SU with an internal float, like an HIF38.

rebuilding a carb is easyer. i found it the most relaxing thing i've done in a while. althought i did buy a cheap carb just to take apart 1st.

another handy gizmo to use when setting up twins is the gunsens air flow meter!! makes sure you get the throttle set the same on each carb at tickover!! relatively cheap and simple to use!!
