For everyone who wanted to know, here is a list of all the parts in the GYTR 84 kit. I cross referenced some of the numbers and found out that the cylinder IS a stock 90 cylinder, every thing else seems to be original. The rotor housing and rotor assy (I think thats the oil pump) numbers dont apear to be right but maybe they are just not in the system yet.

yea thats the one i was talking about and how do you get the cam. i dont see it listed so i just orderd one from a 90 a week ago. i have the cylender, cam but the piston and rings are comeing from cali fo it will take a couple more days. but its all useless without 1st gear which i orderd april 6th and still havent got it im sooo pissed!

I dont know about the cam, it may use the stock 50 cam and that could be why the kit only makes 6 hp.

did the oil pump part # ever get figured out because i have all the stuff to go on my bike i just need the oil pump for the basic 84. and all i need is the rotor housing and rotor assembly??????? i have the piston, cylender, 90 cam, rings, gaskets.

nope, still havent figured it out, the guys at yamaha said those should be the right part #'s but they are supposed to be checking into it for me.

hi im not sure where i should post this but as i see it was mensioned in this thread id thought id ask as im new to this forum. i am from the uk so i am the only one i know of with a ttr 50 and want soe light engine upgrades i see that alot of you say about hot cams from the trr 90 and 125 does this really work and whats the best one to get and where if this is in the wrong place just say thanks

The ttr50, ttr90, ttr125, yfm80, and the yamaha breeze all share the same cam design. The breeze cam is the biggest of these stock cams and works well in ttr50's and 90's. hope this helps.

P.S. the factory breeze cam costs alot less than aftermarket cams, I think it's less than $60 USD>

Mike,



Don't you already have those parts since you have the GYT-R BBK on your TTR?


David,

Yes I do on my GYTR BBK but I'm buying another one that has a 88 Kitaco kit on it without the GYTR oil pump and heavy duty clutch and I want to install these on that one as well as well. I dont have a BB pipe on my bike now just a regular FMF powercore. Looking at buying a bbr BB pipe. You want first dibs on my regular FMF powercore? Probably be the end of this month before I sell.

For those of you who dont know, Powroll now offers a high-compression piston kit for the 50 that uses a stock 90 cylinder or it can be used in the GYTR bore kit. 11.5:1 compression with GYTR kit and 15:1 compression with the stock 50 head.

Well I made some progress with the Clutch disks today, they are available under the part numbers on the first page of this thread (friction disks) They retail for like $48 and they are available from yamaha dealers. There is no pressure plate, just the two disks.

We spent like 2 hours trying to figure out the oil pump, we know the part numbers and they are also on the first page, rotor housing, rotor assy., pump cover, and the pump cover gasket. The pump cover gasket is the only thing that came up. The dealer was on the phone with some guy at yamaha direct when I left and he said that he would get back to me tomorrow with results hopefully.

Justin... exactly how my trip to Yamaha went as well. Parts guy says oil pump not available. Pretty much can get all of the clutch stuff, as far as the pressure plate not sure... I see the clamp listed with the clutch items, don't know what that would be unless that is the pressure plate??
