more top end!!!

[zilladragger]

im looking for any suggestions or advise to get the most out of my quadzilla. having a hell of a time findind stuff. its all for 88 and up. i need 87.
current set up....
wiseco piston
mild port job by ct
dg pipe and silencer
ported stock carb
boysen reeds
13/40 gearing
does anyone make radvalves for the 87??
is the coolhead worth it??
what size carb should i get??
it runs great now.... i murder my buddies 500 predator, drag and top speed. have hit nearly 90mph so far,
also who still makes swingarms for these, stock or extended??

ditch the DG pipe and go with a Dr Q. The Dr can also do a better job porting if you've got the time and money. A lot of guys prefer the ported stock carb setup, but some go with a 41mm Keihin PWK, and i think some guys run 44mm Lectron carbs...personally mine has a 39mm pwk, but I want to bump up to the 41. You should have the stock head rechambered, the coolhead really isn't worth it in my opinion, because the coolhead domes need to be rechambered as well.

Lonestar makes swingarms, stock and extended, but hold onto your wallet when you price those ($1200+), and Burgard makes them also I believe. Theres a few other not so well known companies that do them too...

if your just looking for a cheap way to pick up a little top speed, try running a 38 tooth rear sprocket....

Hell, a stock pipe performs about the same as a POS DG pipe. Even a crappy FMF pipe is a major improvement over the DG.

Theres a 4" extended swinger on ebay in the stores listing for $400.

A modified stock intake for the 87 still outperforms the Rad and V3 for the 88-90.



Ditto on the coolhead.

Visit the LT250/LT500 HQ to ask the zilla guys over there, they will help you out.

Where did you find the +4 swinger on Ebay? I looked for like an hour and can't find it.

the porting from ct is usually terrible ... the pipe choice is also not helping you out

ct sucks i can tell u that from experience i have a 540 dr q motor with a 48mm lectron that no other zilla builder can come close to and i have riden a ct and duncan zilla

[lvwireman]

what about those cool lookin ct pipes that stop with silencer just behind front tire...cool but no good huh???

[zilladragger]

thanks for the info. money is not an issue. i want to get it done right, i have heard about dr.q before. can anyone tell me any contact info for him. bottom line i want the best of EVERYTHING for my zilla. if dr.q is the man, then thats where i want to be. just need to know how to get a hold of him!!! i have seen an aftermarket intake for it, should i use that or just have the stocker modified?? def heard mixed reviews about dg pipe, but it was all that was available, and i got it with the ct porting. if i kill 450s with this set up.... cant wait to see what it will do with the good shit!!! any contact info would be greatly appreciated
