ruff_rida69 Posted February 24, 2004 Report Share Posted February 24, 2004 you should'nt have to get new pistons with just a honing unless the bore has alotta wear on it, as for domes I would talk to dlnoss im sure he could hook you up.

JayFressh Posted February 24, 2004 Report Share Posted February 24, 2004 Depending on *how much wear there is* you should be fine with the pistons that it came with but invest in a new pair of rings. Dome wise I'm not sure. Quote Link to comment Share on other sites More sharing options...

Meat Posted February 24, 2004 Report Share Posted February 24, 2004 Make sure you get "big bore" domes. Noss doesnt sell big bore O-rings yet so hook up with a pair of big bore dome O-rings from Vitos' or somewhere like that. Iv been using the smaller standard size dome O-rings on my big bore domes and they worked fine for awhile, but I did blow 2 of em out. You have to really stretch standard O-rings on big bore domes, but they will fit. Bitch to work with tho, so try and hook up with big bore O-rings for your domes. Also Nax, no one gets big bore sleeves installed in thier cylinder without having some porting work done, so find out every little detail about the port job on the 409 juggs. Anything more than a trail port is not ideal for XC racing, you want a motor with a low end style powercurve, porting for low end aint gonna happen. You'll also want a smooth powerband that wont tire you out, anything more than a mild trail port is going to be a handful trying to race for two hours in tight woods and muddy and rutted out trails. Bigger is not always better, espcially when your talking about XC racing. The top guys out there racing xc are using engines sizes around 300cc's. 250r quads with powervalved single cylinders between 265 and as big as 310cc. A 409 ported twin cylinder Banshee would be a handfull in the woods, especially for a 15 year old amature. Just something to think about Quote Link to comment Share on other sites More sharing options...
