In the process of working on two winter projects and one of my winter projects (1990 CBR250RR MC22) had a bent funnel/velocity stack. I can't seem to locate one for sale, any recommendations for moving forward or know of a source. Thanks!
Thanks, I have the part number but 16141-KAZ-000 and 16142-KAZ-000 don't come back to anything in stock anywhere.
this guy seems to have a set. are you in Australia? https://www.gumtree.com.au/s-ad/lep...=socialbuttons&utm_content=android_VIP_sticky
Why not just straighten it, it's very soft aluminium, avoid using metal tools on it and stick to wood, thing like hammer handles and the like. I think you'll be surprised at how easy it is.
I may have an extra set that came with the airbox. give me a day or two to get out to the garage and dig them up
I do have an extra set. There are slight dings that may be hard to show but I can try and snap pictures if you want
now I'm confused... All 4 stacks appear to be the same height. I swear the inner ones are supposed to be taller. There is only 1 in almost perfect shape, but it has a ding on the outside of the lip. I can throw you dimensions of what I've got and pictures to see if its what you need.
I have read that for racing, when people can get their hands on them, the two inner stacks are replaced with the shorter outer stacks. IIRC the length difference is there to assist in getting through a dip in the torque curve as the engine comes onto the cam.
I was just in my airbox today and on an MC19 the outer and inner velocity stacks are two different lengths. looking at @GreyImports parts diagram it looks like they're all the same part on the MC22.
That parts list shows that RRL and RRN have 2 different Vleocity stacks and RRR & RRR-2 have all 4 the same. I would assume there are some engine or carby etc differences to account for that as all 4 designations appear to be be for MC22. POssibly different year models...
I found someone one facebook who had a set attached to a parts carb in Australia who was willing to ship them state side. I have procured a good one and now have a spare carb bank to rebuild and have ready when I need it. While I have folks attention. I have never played much around with Carburetors with the exemption of airplane/bendix carbs. When rebuilding the carburetors is it recommended to treat the O-rings with fuel lube or silicone grease? or assemble dry? This is what I am referring to. EZ Turn Lubricant | Aircraft Spruce
Usually a light coat of rubber grease. Silicone grease would work too. Keep in mind that most of o rings in carburettor will slightly swell after some time in contact with fuel and this is factored into the design.
I use INOX .... in fact I use it for everything .... every nut, bolt, screw ,thread ,electrical or wateva
Hello, I am looking for two of the short intake stacks for my CBR250RR. I am doing a full exhaust system and per the tuning guide, I need to run four of the short intake stacks. Factory, mine has two of the longer stacks in the middle. I am in the United States, but I’m willing to pay shipping to the United States if anyone has them. Thank you.
