I have a guy that is going to do trail porting and a bore on a 2000 scrambler 400 jug. My question is has any one ever put the new style cylnder on an old style motor... basicly NEW = concentric....old = non concentric. I know they use a differnt carb boot, but other than that what issues will i have?

 

i have done this several times and had no problems the carb boot is the same also the only year i know of were the 94to early 96 had a angle slightly differant on the reed housing

 

huh wel lthe guy thats doing it for me said that the older style motor uses a boost bootle while the new one has boost ports!?...?

 

Boost bottle? The scrambler doesnt use a boost bottle. I hope this guy knows what he is doing.

 

UHH Me Two!?

 

Might be better off letting Rick Ritter do it. That way you know that you are getting a quality job done right the first time

 

The 2000 cylinders are identical to the 1997. It is the 1994 , 1995 and early 1996 that are different because of intake angle .

Your mechanic is correct , the 1995 and early 1996 Scramblers had boost bottles . He is also correct that the older cylinders had no boost ports .

PS - I have ported cylinders in stock ready for exchange . Wait time ----- zippo ----
