Ohton Racing in Arizona can build you a 7mm using stock cylinders that will hit very close to 110hp,this of course is an all out drag set up.

55-60hp can easily be achieved with regular bolt ons and a good port job.

 

~Shakes Head...

Sure cant get that with a raptor, by just doing that...

-bLuRRRR27-

 

Mission Yamaha upper and lower port work, Pro Circuit Pipes, Single carb 34mm kehien, cool head 18cc domes puts me about 57.

 

only pipes,reeds,filtercharger,porting (trail),and heads.
timing set is also a must,than jet the thing and it cost alot less to have fun than on a thumper,lol...

 

where can i get one of these adjustable timing plates, and about how much? Also another question does anyone have reccomendations for porting, like who to take it to, or who does it best and also about how much. thanks

 

mine has 58.3 horses.

 

Ricky Stator.com for the adjustable timing plate. For the porting look no further than Passion Racing, you cant beat a 12 port done by Jim. Try the bansheehq.com forums, he is a member there, and you will get all the info you need.

 

thanks for the info, i have a couple questions about the porting. About how much HP gain should i expect with my set up and one of those 12 ports done by jim. Also where is he located and just about how much? once again thanks for the help.

Many builders out there that can do you well over 55-60 horse with just pipes, filters, reeds, carbs depending on budget, and portwork.

A&S has gotten 117 out of their 7mm, ive also seen 95hp stock stroke 350 banshee as well. That gives you an idea of what a stock bore/stroke motor can put out.

Advance your motor 4-7 degree's depending on what you motor likes. K&T, vito's, ect sell's timing plates so its not a rare commidity.

I would go with a builder like K&T, A&S, ohton if he has time to do it, patriot would be my recommendation right now though, Dan is an awesome guy and like previously stated, he got 95hp out of an alk 350 with inframe pipes! Dans the man
