MurphyL17 Posted October 4, 2005 Report Posted October 4, 2005 Im thinking about getting a pair of mikuni 38mm flat slide carbs for my banshee. Im having trouble finding some of the info im looking for: can i use the stock throttle cable with the carbs? Where do i get the bigger intakes needed for the carbs? Please leave any suggestions for the set-up. Thanks! Quote
Ducman Posted October 4, 2005 Report Posted October 4, 2005 I run the TM 34mm flatslides. I got the carbs, twist throttle and cable from Motocarerra.com It is easier to find off the shelf manifolds for 28-36mm carbs, modquad has some nice billet ones at a good price. Cheapest way to go is some UPP stock style rubber intakes (look in Magicracing.com). I have seen two 38mm carbs on a banshee before but it had the cylinder intake necks cutt off and rewelded/replaced with YZ 125 necks, reed cages, and manifolds. Looked almost like stock bashee intakes except the 38mm carbs gave it away. This was a pricy setup on a totally tricked out motor using stock cylinders that were made by a builder for his personal sand banshee. I know someone makes the manifolds for 38's though, but I cant recall where I've seen them. As far as the cable, I just bought a new cable with the prodesign twist throttle, only about $50-60 for both if I remember correctly. Stock throttle will be fairly harder to push compared to stock carbs. If you get a set of TM 34's I can give you some jetting tips. Quote
rocketboy Posted October 4, 2005 Report Posted October 4, 2005 i also ran the 34mm mikuni flatslide carbs in the past ,notice i said past...i now run pwk keihins for many reasons Quote
wayfst Posted October 4, 2005 Report Posted October 4, 2005 38's are huge, I don't know that your banshee will have the air velocity to make things work right. Quote

rocketboy Posted October 6, 2005 Report Posted October 6, 2005 (edited) can you elaborate and give us the reasons why?thank you 422988[/snapback] first off, ill say some people have had great luck running mikuni flatslides,i however didnt. the fuel inlet spigots arent the right size for the fue lline on mine ,the carb bodies are cumbersome ,huge, and barely fit into a banshee frame ,the parts are all special order and alot of shops wont carr y the stuff youl lneed ,the tm carbs have all these orifices and seats i swear these things are like womans vaginas... theres holes ,plugs, drains ,and tubes and shit just alot of unneeded dickin around IMHO ,the Keihin pwks reved faster and smootherand higher on my setup and jetting is a breeze ,plus theres more than 3.5 people on earth who know how to actually get them to run right too! :confused:the flatslides arent like the ease associated wit h the stock roundslides IMHO . :huh:38mm is beyond huge even big for an alky bike. overcarbing your 350 will only make you lose power Edited October 6, 2005 by rocketboy Quote
Ducman Posted October 6, 2005 Report Posted October 6, 2005 I've had 2 things that I have caused me trouble with the Mikunis. One is figuring out what needle jet orafice (dump tube) to use to get the jetting dialed in for the needle (you change orafice size not the needle on TM Mikunis, unles you need to fine tune the needle taper which I didn't need to). The ones they come with are way too rich. (they cost $16 ea and you have to order them, fortuneately I got good advice and got the right ones the first time). The second is that they were too tight to make jetting changes practical using the stock air box so I had to switch to pods, no biggie. Otherwise, jetting was easy and a lot more similar (pilot and main jet # wise) to stock carbs than using a Keihin. I agree, you probably dont need 38's on a typicall ported motor, however, the motor I mentioned above had 38's and it was stock stroke, hightly modded stock cylinders running on gas, and it had the best HP curve I've ever seen. Insane power from down low all the way to 78 hp peak above 9k. Not a drag port at all, more of what most would call an MX port, even though the guy uses his bike exclusively for sand and sand drags. Of coarse the guy owns a dyno and can play with different tunes/ settups all week long untill he gets it perfect without ever leaving the shop. Although If I remember correctly, they were 38mm pwk air striker keihins too, if that makes a difference. Quote
