unless your goal is to spend $$$ and lose power, that is"


i then said i had +1 ti valves put in and definatley didnt LOSE POWER.
im not saying oem valves are bad, im only saying there is gains from them! not a loss in power like you say.

so you had +1s put in with no other changes? no port changes or anything? dyno before and after with just the valves being the change?

how can you even judge the power if like mixxer said other things were done to more than make up for any loss. for all we know stock ones could be making the same or more.

Well im not going to set here and argue back and forth with you and mixxer! If you guys think stock valves are so great continue to run them. i Know what gains i got from +1s and could care less if you two believe me.

putting in a big sh!tty valve wont make as much power as putting in a big good valve... no question...

the stock valve profiles are excellent by yamaha design and intent...period

Well i must have not got the big Sh!tty valve you speak of. For some odd reason they added power to my bike. Must have been luck. or maybe bc i didnt have a to put them in and port my head. Maybe you should look in to outsourcing your porting if you cant get gains from +1's.

Hmmmm...I also did over sized valves, +2 center intake and +1's on the exhaust side. Stock outer intakes still. I picked up 3hp on the dyno. I must of got the good ones. Oh that's right I got them from MMAD and not Venom, that's why. Oh and I have the dyno sheets to prove it incase there's people that disagree.

We must have gotten valves from the same batch.

Where did I bash? You're a pathetic waste of oxygen.



You're hiding behind a fictitious name. Here I am, where/who are you? Many people AND reputable builders know me personally. Who are you again?

Oh that's right, you're an insignificant forum "rock star", like some others around here. Sack up, coward. Identify yourself.

My name is derek (obviously) and if you search the ltr forum my screen name is exactly the same. There you can see my profile and other statistics. I am not a big name racer or engine builder. Just a regular guy who likes to ride.
I apologize for making you so upset. I did not mean to hurt your feelings. I am sure this forum was not intended to create drama. I was just trying to help out my buddy (jake) by filtering the good info from the bad. You still have not given us any good info. Just .

You'll never hurt my feelings. Instead of typing your nonsense and adolescent drama in this thread, why didn't you just ask "your good buddy (jake)" to FWD my PM to you? As I stated before I have nothing to hide. Come correct.

I'm not going to knock Chris Williams on either forum, but if Robb sends that motor to Chris and it comes back without a remedy for something that is obviously not right.. I will voice my opinion loud and clear on both sites like I always do anyway.

Jake, Florida is alot farther away from TX than Arizona. I would suggest sending your motor to Kenz Cycle Tech in Mesa, Ken is making good power with the yfzR's. Racers Edge isn't too far away either, in Tucson AZ, but John doesn't want a yfzR in his shop from our last conversation at the races..

There's also the popular MMAD but mixxer is a site sponsor here and goes apeshit when he sees it. Geoff did offer to me a promise of a very reliable pump gas 55 horse yfzR motor last year at a race, that I considered for awhile. Reliable meaning it's got to hold up for 500 miles non-stop in a dusty climate.
