ok i am wanting to bore out my stock carbs to 28mm. will i have to rejet them after i get them bored out? also whereis the best place to do this? graydon prolin, lrd, where? about how long does it usually take? need help fast

 

anyone know??

 

Going up only 2mm in size, and sticking with the same model/type, my intial response would be no.

But....I don't think I need to hammer home the "you should always check", but....you should always check.

Give LRD a shot. Shouldn't take more than a week or so, but it will depend, as always on current backlog.

 

I was going to say LRD myself. Actually though you should be able to find someone localy who can do it. I know there are people around here who do it. I really dont know how much that is going to help though.

 

Backcountry and Brandon:
I have a bunch of mods on my banshee also.. I still run the stock carbs for now..... I was thinking of going to a set of 28pwk's so that I dont lose throttle response and alot of low end. My suggestion for blue-banshee would be to go with a set of 28pwk's. From what I have heard from many of the major motor builders is that the bigger you go with carbs (34's 35's) the more low end you lose. I live out here in New England and I dont get to the dunes that often. I am looking for the best of both worlds.... My next step is going to be one of Rick's (MacDizzys) 400 long rod motors, and I feel the 28's will be small for it but will still be able to run it.. or will they?

Blue-Banshee; a local shop near me will smooth bore or rifle bore a carb for 40.00+/-. Any local shop should be able to perform that task for you

ok thanks i wanted to know this because i am building a quad (project-build-a-shee) yes i said build a quad from allth parts i have left over from what i have exchanged on the other two shees. i am wanting to make this banshee run good but still have the stock ppearance(stock carbs, stock head but shaved, bored out cyl., and i might bring out the dremil myself and do a little ggggrrrrrrrrrrr)

 

When LRD makes their long rod banshees, they use the 28mm pwk carbs. It seems to work well for them so you would probably want to call them and see what they have to say. Arlan would be happy to answer all your questions.

 

I know I have talked to Arlen at LRD about boring the stock carbs to 28 and he said that it is a waste of time and money you end up with a airleak around the carb slide at a idle and part throttle his sugestions are to go to a 28 PWK I talked to him about going larger then that and he said that you do not need larger then that till you get up in the 400+cc's

 

I looked into this myself. The cost was about $40 a carb. They told me it would work, but it would be alot better to buy a larger carb and to go with the flat slides. They perform better. I understand what your gonna do, but if your gonna do it, you just as well do it right. Good luck.
