monster_energy06 Posted March 12, 2008 Report Posted March 12, 2008 (edited) ok i ride mostly pits and play around. i like bottom mid range pull to climb, but top end is fun to have. soo far i have pc pipes vf3's, air filter pods no air box with outerwear, tors delete. from what i know engine is stock accept for wiseco pistons and dirt digger clutch kit usin heavy duty springs. bike ran good and strong all summer last year not one faliure. now i want a stronger and faster engine. what would be my best choice as an engine pkg. i already have mikuni 34 tmx flat slide kickin around and i have the cables for them. soo i would like to use them.i was thinking about a cheeta kit 400 or 420 with power valves. maybe just a 4mill with porting still not sure.anyone plz shim in give me some ideals Edited March 12, 2008 by monster_energy06 Quote
okbeast Posted March 12, 2008 Report Posted March 12, 2008 What's your budget? Also try doing a search on this if you can, alot of "what should I build" topics out there. Quote

Also try doing a search on this if you can, alot of "what should I build" topics out there. budjet...not sure all depends on what catches my eye lol i know a cool head and impeller are in order. soo dome change and cooling wont be a problem. the carbs are one less thing to worry about i had them only got a cable ... as for the search. i already did. and i didnt find anything of my liking.. if i knew the answer i wouldnt ask. tx for yur response Edited March 12, 2008 by monster_energy06 Quote
Hilarious Posted March 12, 2008 Report Posted March 12, 2008 A dune ported 4mill w/ drag pipes on race gas makes a very fun ride. Quote

Ought to push around 65-68 hp and have a pretty nice torque curve with those pipes. Quote
monster_energy06 Posted March 12, 2008 Author Report Posted March 12, 2008 ide like to keep my pro circuit pipes and use the 34mm's im looking for sometin that will work with my parts and used for the type of riding i do Quote
okbeast Posted March 12, 2008 Report Posted March 12, 2008 Well ur prolly gona have to decide if you want more low-mid, or mid-top power. Sounds like a play/dune port would be right around your liking and would work with your parts you have now. Quote

Snopczynski Posted March 12, 2008 Report Posted March 12, 2008 (edited) Well you got too big of carbs for pro circuit pipes, so you either need to switch pipes if you want a mid-top motor, or switch carbs if you want a low-mid motor. Pro circuits sign off at 8600 rpm, and with a 34mm carb they will never use the amount of air they can move. With 28mm tm mikunis you can use the smaller bore for velocity and better throttle response, and the ovrall diameter will be ok to 8600rpm where the pipes stop working. So you can run the 34's, but they wont run as good as the 28's will. For the riding you do, I would switch carbs and build a bottom-mid motor. A dune port is still considered more of a midrange port job we run pro circuits with 35mm 2 into 1 carb, and/or dual 28's on those port jobs. Edited March 12, 2008 by Snopczynski Quote

Snopczynski Posted March 13, 2008 Report Posted March 13, 2008 I listed the mods you can do above in my first post. For a good bottom-mid engine porting guy there is Dan at patriot racing, Dave at ILR performance, Rich's guy at Dynoport or me. Sell the carbs and get 28's. A set of tm 28's runs around $350 range. You could probably find pwk 28's easily also. All the stuff I have done is mentioned because of crank dyno testing I have done on the components talked about. Quote
