Hello to all, old Kaw racer, new to KX 500 though

<< < (3/4) > >>

Larry Wiechman:
 
 Why not add the spray on the other side of the reed cage and eliminate the cryogenic shock to the composite reeds?

DocsDirtbike01:
Its funny you mentioned that Larry, I thought about using it as the spacer plate, just might have to rotate foggers, or if running just one fogger, then move it to a desireable location. I think the vforce reeds are carbon fiber, that may be why they disintegrated, Im unsure of the materials resistance to extreme hot and cold.
Now Ive read several older posts about Carbs, whats the best choice for WOT racing applications? Ive seen some prefer one for trails, or wood riding, or that another provides best miles per gallon, but which makes best HP?
I just noticed a sleeve for a the cylinder on ebay, would it be custom made or is this a part that some aftermarket company has available?
This is a question for Jfab or stewart. ive seen pics of the work you guys have done reshaping heads and setting up squish and CC's. Once the head is shaped, are the insides then polished to resisit heat build up in one area or over casting flaws or imperfections?
Is this also done with the pistons? I have shopped around for pistons, I really like the wisecos available with the window, are these sold with any coatings for friction or heat? If not, can the top be covered for heat resistance and the skirts for lowered friction?
Sorry for the questions, I usually have a few....

DoldGuy:
I have a 250 cylinder that was plumbed after the reed cage and also in the transfers. Will try to get a pic & post.

RoostDaddy:
in my opinion the 44 Lectron would be your best choice of carb for WOT racing.

Not too sure on what sleeve you found on ebay, but if you want a big bore sleeve, I would check out Advanced Sleeve out of Ohio.  I think their sleeve may start at 86mm and go to 89.5mm for the newer style cylinders. (up to 88mm for the 1988's)
Some guys on here dont care for sleeves, but others think you'll be alright running one.  Take it as you will.  I would think it will save you money in the long run if you want to start stock bore and go bigger down the road.

hope this helps till someone else chimes in.

cbxracer30:
Cometic will make that copper head for you in a bunch of different thickness for you just give them a call. Also for the stronger head bolts Roostdaddy is running heavy inserts in his cylinder ,not just heli-coils, and I think they would work great with heavier grade bolts cut to length. Also if you talk real sweet to Moto tassinarri they will make you reeds out of heavier carbon-fiber , but it takes a litle talkin, or Roost again has a guy that makes them. CBX
