Carbs or not

[yama_dog_350]

Trying to find out if my stock carbs will do the job or if i need new ones.

 

My bike has ADA racing head with 21 cc domes, rad valves, reed spacers, boost bottle, CPI in fram drag pipes, degre key already on it.

 

I have a stage III port job coming along with a 4mm stroker crank, weisco pistons,hison clutch basket, pressure plate,clutch, and oversized raidiator on the way.

 

Also if you have any ideas that will help make my shee faster id like to here them. I'm not to conserned about price but id like to keep it within reason.

Stock carbs will work, but not to your motors full potential. I would say some 30 to 33mm carbs would best match your engine.

33 pwks all the way, lighten the fly wheel also for faster revs

what kinda porting? low end or more top end? for low end id go with a 30 or 33 mm pwk carb. if you are looking for top end id go with some 35mm pwk. stock carbs are gonna severely decrease your power potential with that setup.

Now im not real sure by low end or top end i got into 2 strokes just in time to not have much time to learn about them. I'm trying to build the bike for dunes with the potential of still using it in the woods. open to sugestions.

 

sorry it took so long in the middle of getting settled in the new place

Always a good idea to ask your builder !! I personally would recommend them if you can afford it!

Took the words out of my mouth. With a 4mm crank in there It's gonna be anywhere from 33 to 38's depending on application.

Alright so we got 35 mm carbs now would ya all recomend lightining the fly wheel if so can i get this done at a machine shop? Also I don't trust other people touching my baby so there are no builders invalved other than me and my brother.

Some smaller domes would give you more compression=more HP.I'm thinking 19cc domes,but then you would probably have to run race gas.Someone correct me if I'm wrong.
