Schizo Posted March 12, 2004 Report Share Posted March 12, 2004 Advance timing 4+ degrees and add vforce for better flow and if you have very mild porting you prolly wont need much bigger carbs, maybe some 28 or 30 keihin pwk's. Since you are running race fuel already it wouldnt hurt to go with some smaller domes to increase your compression, timing advance and more compresson makes a big difference on low end power but you would definately want to consider getting the crank welded if you add compression.

MotulMonsta Posted March 12, 2004 Report Share Posted March 12, 2004 Your running a 404 kit on stock 26's????? Get yourself a set of 30 or 32's carbs and let it breath!! Quote Link to comment Share on other sites More sharing options...
smokin350 Posted March 12, 2004 Author Report Share Posted March 12, 2004 yea i deffinently see where bigger carbs would help and the v force and as for smaller domes i have a bigbore so pro-design has 2 different bigbore sizes 24cc for pump and 22cc for more compression and race fuel and let me tell u what a difference. thanks anything else.

fixitrod Posted March 12, 2004 Report Share Posted March 12, 2004 I don't see what kind of pipes you have or what type of riding you do. I also am very shocked you are running a 404 with stock carbs. That's a lot of vacuum for those carbs. I'm also suprised you don't have the timing advanced. 4-5 deg works good on gas and most pipes. v-force will get you some more "snap" and smooth pull on top. A lightened flywheel would be awesome on a big motor like that. Compression is something else you can play with. If you want to run higher compression you'll need higher octane fuel. Billet parts will make it lighter. We were suprised how light cotten eye joe's quad was. He has a lot of billet though. Quote Link to comment Share on other sites More sharing options...

Don't see anything to add here. Carbs, reeds, compression, timing. Sounds good to me. Quote Link to comment Share on other sites More sharing options...
smokin350 Posted March 20, 2004 Author Report Share Posted March 20, 2004 thanks guys i start with the carbs and v-force i'm sure i'll be back asking jetting questions for the carbs and also what size carbs do think i should get? Quote Link to comment Share on other sites More sharing options...
Oilsmoke Posted March 20, 2004 Report Share Posted March 20, 2004 Personal you should contact Noss Machine and see if David will cut you a Custom dome for the Big Bore in a smaller size 19cc maybe. I sure he can do it. Than your Race fuel Not a waste of money. It will wake that bitch up for sure. Quote Link to comment Share on other sites More sharing options...
geaux 4 it Posted March 20, 2004 Report Share Posted March 20, 2004 Weld the crank!If you worry about reliabilty.If you want to go fast do some more porting to it.Just don't cutting up the cylinders where it will start eating the pistons & rings.

. Posted March 20, 2004 Report Share Posted March 20, 2004 I agree, go for some custom cut domes, carbs, reeds (dual stage boyesons at the least, and if you get the carbs you need the reeds), HO stator and plate from ricky stator is always nice to brighten up your world (could get some handlebar mount lazerstars to add on) I'd definitely advance that timing and open up that intake for better airflow. And keep a close eye on your compression.....dont ruin that top end with a crank thats gonna let go....its just not worth it. Quote Link to comment Share on other sites More sharing options...
