Any chance you have some of his 103 stage 3 with different cams?

 

103 t-man stg 2 heads and 625 cam the stg 3 heads will produce approx 3-5 more hp/tq and carry it out further in the rpm range.

 

pretty consistant numbers dont ya think john.

 

SE - Thx

Trying to find a setup that continues to climb higher than 4k and still retains good down low numbers.. I know, dont we all...

KRAZN8 - sorry to hijack.. sounds like were both looking into the same

 

in a 103 thats going to be pretty difficult as the smaller cubic inch motors will make their power at a higher rpm then a larger cubic inch motor.
look at a 107 then. more air to feed the motor you will be starting off with more cubes.
lets take a 120 and a 117 that i am very intimate with.
both bikes have same cam and similar pipes one is carb one is efi.
both bikes have approx 120 ft lbs of tq at 2200 rpms. and both bikes will rev out nicely and peak with their power in the lower and upper 130,s to 140. the best of both worlds.
but
these bikes require a lot of attention . they are not for the average rider who is just looking for more power they require a lot of concentration when riding and throttle control
remember a larger cube engine will have more power down low then a smaller cube engine at max rpm.
look around some builds claim to have 115 hp tq yea thats at 5500 rpm
the builds i mentioned have more then that at 2200 rpm and a lot more at peak.
a good solid 107 build will give you plenty of power down low and rev out nicely.
that 103 with a simple cam change and a bump in compression will give you plenty of power down low and still rev out nicely to mid to upper.

you cant have it both ways unless you plan on building a larger cube motor.
also pipe and tune play a major role i it also.

dave has a bike he is doing now the head work alone is going to cost more then most guys spend on their entire builds including crank work and tune.

 

George is correct. And I thought about that... 120 tq on a wet expressway ramp at 40 degrees outside Loaded down with gear? I ride 20k+ a year in all weather conditions.

So I built a 107 which still is a TON of fun! It is a blast compared to a stock or simply cammed bike. 90tq at 2100, goes over 100tq from 2500 to 5500. Not too much to handle. Nice conservative designed ride. The 116 tq is where one would expect it to be and can use when wanting some spirited riding.

 

PhilM: Glad to see someone picked up on my post. No doubt a 103 can turn some good numbers....but you usually don't see it on Both axis. My little old 103 only made 120TQ and 112HP...and the naysayers said it was "magic dyno". I knew otherwise. Glad to see others with similar results.

 

I agree, my 113 makes good torque down low and I like this as long as the roads are dry ,but when I am riding in the rain with a rear tire that is half worn out it can be a little unnerving at times and it is those times that I wish I had a little less tq on tap at 2200 rpm"s ,this feeling does fade quickly once the sun comes out and the roads dry up.

 

T-Man parts are top quality. TR will talk with you on what your trying to achieve and select the parts you need. I've been running his stuff all year with great results. Love his 590 cam!

I'd like to know what parts you're using to build you 113" (sorry, not trying to hijack the thread). I have a 113" going together at this time also.
