Air Filters

Post  Snails on Mon Jan 19, 2015 4:32 am

Anyone running a K&N air filter or similar and can supply a link of where to purchase from. I was running one but it fell off and is now lost in space. Looking at the K&N site they dont seem to have any options for 25mm carb size (which is the outer size of my SH1/20 carb mouth)

MB sells foam filters that size. You may want to consider one with an elbow to give more clearance away from the kickstart. Or go onto the Dellorto UK site they have all sorts of air filters.

They say it does. BIM that the Vega carb has no lip to locate the air hose securely hence their propensity to let air filters fall off. Don't ask me how I know!

no carb as well if I can get it to fit? Impossible to get a replacement 20mm and i think my carb is a bit shagged.

tim, theres plenty of 20mm carbs around, granted they are all used, not many true vega 20mm carbs, but you can easily fit a screw in pull up choke plunger to another carb, rather than have the vega flip choke.

i know there are 20mm carbs around, but not Vega ones. i think there are some differences between Li/GP 125 carbs and Vega carbs. Just looking for something new and also where the filter won't fall off.

Hi Tim, if your looking for something different, we have used the Polini Cp 21mm Carb on a 125 Conversion with good success. Chiselspeed sell these, the filter & do the manifold conversion also (Buy new, or supply a 150 manifold). I'm sure he could do something if yours is a 75cc? Hope this helps....Steve

Trosky - How much did the carb set you back roughly?

Are you saying a 150 manifold is all you need for the conversion?

Would you say the carb offers better performance than a sh1/20 for a 125?

Tim - I have a spare Vega sh1/20 needs a bit of an overhall. I was waiting for someone to confirm whether they wanted it but if they don't it will be up for sale soon.

Hi Snails, I think the Carb itself cost about £80. The guy I built the Vega for took it back to Chiselspeed to have the engine dynoed & carb dialled in. Gave about 5.5 BHP & about 5 in torque I think? Standard J 125, exhaust & electronic ign. Steve says it starts,rides & pulls smoothly. To date there have been no probs with Carb & is not harsh on fuel consumption. Hard for me to say if it's better or worse than SH20 as I haven't used that combo, we needed a carb for it so tried the Polini. It seems a good alternative if you can't find original items.
Yes the kickstart sits close to the filter with a Vega Kickstart but Steve has used a J one for his own preference. Personally I like the Vega kickstart (you could just move the kickstart down a spline). So long as you're aware of it when starting, then there shouldn't be any issues. We had a 125 barrel & all that was needed was the manifold machined to match rubber mount I think? A longer Throttle cable maybe needed also.....Steve

Thanks Trotsky, those Polini carbs in a few different sizes. did you not have to seal the vaccum tube on the carb? Found a 19mm on ebay brand new £54, will still need to get the manifold and the rubber mount, and probably use the primavera type filter, as it won't fall off.

Snails thanks for the offer, and I may come back to you. I just want to start with something new, rather than a 30 year old carb.

Hi Tim, the carb came with black rubber bungs that go over the tubes - was as simple as that. I'm sure we got the rubber mount from Chissys as well? Worth giving Martin a call, he'll see you right....Steve

polini carb

Post  boozee on Sat Jan 31, 2015 1:33 am

hi, chiselspeed just supplied me with one of these carbs fitted to a atomic reed valve.using it on a tzr conversion.nice and compact little carb. only issue i had was clearance on cable adjuster.also the manifold inlet was offset from the port on barrell.sorted these minor details out by making a packing plate and shaping it to match them up.

Ah. Found my link for the air filter that I had fitted

http://www.hilevel1.co.uk/hilevel/index.php?main_page=product_info&products_id=6691

I could buy another but as I could never get it to run properly with it on and also as it fell off I have my doubts as whether that is such a good idea. Although there is probably nothing to say that the bad running was necessarily the air filters help. I wonder if there is much variance between what one air filter lets in an another?

while having a bit of a rake around in my shed, looking for something else completely, I came across an old K&N Filter that I used on my first ever Vega I built (before the air boxes had been remade)
here is the part number.

Thanks Daz, Cant seem to find one with that part number - or at least a way of identifying which it is and the K&N site does not allow a search by part number. Also they dont see to start any with an F - anymore at least
