strange results
Since at the begining of the year I tought that I was going to race I brought a gsxr 1000 year 2002.
the bike was kind of slow, so I put a bolt on, cleaned the inyectors, all the usual stuff, BMC, at the end slow bike, no mid range.
Not happy.......
then motoman was at my home and he told me that he whanted to see the head of my gixxer, well, I could not say no to a guest of my house and a friend.
he told me that he whanted to experiment with the head something, port related.
he did his epoxy thing.
The bike became very fast, In the track I could notice that the big $$ guys could not leave me. Maybe It was me..... right
Accident, and engine was damaged..... 2 months later engine back toghether and bike for street this time, 2 more on the back only, bolt on and filter.
yesterday a R1 2006, full acro, PC3USB and -1 on the front, came to my house and he whanted to race the monster (known here ZX12r) I said, lets see if you earn it with the gixxer, he was beaten several times with every gear.
today same guy with a stock BUSA, same story. beaten by a gixxer with a bolt on on 125 USD, filter 100 USD, sprocket 60 and epoxy 35.
I thought that I was going to be demolished by the R1 and the BUSA..
The zx12r is faster than my gixxer, what is all the buss with the R1 and busa.
Wy buy a new R1, this gixxer was only beaten by a K5 with full yoshimura and +2 on the back and PC3 (of course tuned by me).

you are friends with the famous Motoman?????
The "epoxy thing" is the adding epoxy to the floor of the exhaust ports or what???

Yes, he is a friend of mine from long, very long time ago.
He came to my house to better his spanish, and visit my family.
Yes he used epoxy in the floor of the port. to get vel up.
Incredible, that is a cheap trick (very hard work) but I dot even have a full exaust. $$$$

intake ones.
the exaust port job is a diferent one and he told me that only a very good welder can do it.
it needs to be Al welded in order to make a step or ramp so the air can go out but restricts it to go back. in R6 it gives like 4 hp aprox.
If you whant pics of the zx12r job I have them. of course is my job. but motoman job is light years ahead of mine is perfect, flaw less.
canadamaxxer has it to and I have his pics 2. he also has a 1270cc

Just curious with that type of work would you want your cams to have a long
duration in oder to fill and take advantage of the higher stacking velocity? What
about lift? Would you want less lift to keep the velocity higher? On the floor of the
intake port was it a gradual epoxy slope or rapid at the end by the valves?
With regard to the exhaust ports is the velocity concept the same but in an exiting
manner when being welded up?
As far as having more low and mid range for road racing how would a set up like
this work for drag racing where the bike will be running in the upper RPM range?
Is the benefit in the launch and 60 foot times?
If you can post those pics as it is an interesting concept, or shoot them to me if you
do not mind. Docbonzz13@aol.com.
Thanks for your patients with all my questions.

In
www.mototuneusa.com
you can find almost all the info you need. Of course I have more info since pics and before the articles where made I was learning from the man.
Regarding cams, Pat have told me that longer duration works best with hi vel porting, and more lift dont do much, since the flow is the same after some point in the lift.
More duration and retarding the intake a bit.
Carb bikes have to go leaner since the vel go so up that the bike becomes rich. My F2 had that thing.
Later he will reveal more secrets about cams, all I can tell you is that he uses his own way of making them, a shop in Europe makes them for him.
I have the concept and seen some pics of the exaust port but cannot help you.
I dont drag race, I do track days, BUt if you have more mid range and more top end, I guess that is better for drag race, My zx12r has more 500rpm since the power just stays there, is sick this bike.
I do roll ons and the bike just get the jump.
I will email you tons of pics that yesterday I put toguether of my zx12r and a cbr600 F2, Its the same.....
But first read the articles and I can help you.
