Mikuni 34mm round slide??

[tripleported]

Hello.. new to the site but not the blasters.. I just wanted to hear your guys input on this vm 34mm round mikuni. The blaster it would be going on has 4 boyesen ports, remaped intake windows huge lol, triple exhaust ports, stock bore & stroke, & the bolt ons.. Just need a base map setting for pilot & main Thanks alot. I:I

might be a little to big, unless you have a crazy port job. Then again it would work but you would suffer low end power but have lots up top.

Well it is a round slide carb.. Its all about tuning that low end & getting the pockets out. I just see everyone runnin airstriker & pwk wanted something diffrent.

my lil bro ran a roundslide 34mm mikuni on a triple ported 175. it had all kinds of top end. I think it'll work out great for u. let us know what jetting u used, i have 2 of those carbs and one will end up on a blaster we just picked up. who ported the cylinder? if u did what method did u use? doesnt exist without pics,lol

LoL your right.. I was going to take pics but im that type of guy who hates takin pics lol. I went with the boyesen ports everyone only does the two bottom i went ahead & did top & bottom. Also the center top boost port has been comepletely opened up from side to side top to bottom. I followed ken onconor on the exhaust port & transfers, I raised the intake windows pretty much to the max limit with out knockin the whole thing out. Triple ports 3/8 size drill bit is the hole size & was opened up with a carbide burr. Man your triples look really nice...I:I

Yea i noticed a big increase in the low to mid range.. I ported my brother in laws blaster all i did was the 4 boyesen ports thats it & it felt way better in the low to mid. I love these blasters! im 26 & would rather have a blaster with like a kx500 engine then a banshee lol...

have u tried 2 at the bottom and then added the 2 at the top? just to see?my lil bro just traded a 78xl250 dirt bike for a bone stock blaster. we r planning on doing one mod at a time just to see how each one adds up.

Yea thats what i mean by 4 boyesen ports... My brother inlaws blaster is bone stock with fresh rebuild all i did was 2 worm holes up top & 2 worm holes on bottom & felt a huge boost in the low to mid rangeI:I

I would deff just do it one by one like you said to see the diffrence. I love my ass dyno & i know how to use it lol..

One thing i forgot to mention.. once i did the four boyesen ports the blasters clutchs started to slip from the extra power or toque it created.. Those clutchs never sliped when it was in stock form lol..

 

[N8tsNastyBlasty]

i meant to ask if u had tried or noticed a difference of running just the bottom 2 vs all 4.?

No that i have not done..

Just to let you know ken suggests a flatslide 34tm not a roundslide. many use the tm34 for port work but I have never heard until now of using a 34 roundslide

 

[N8tsNastyBlasty]

round or flat should both work fine even though most prefer flat.
