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.

Sure. I doubt I'll have the money but check with me first if you don't mind.

My Yamaha parts guy is researching GYTR high volume OIL PUMP, GYTR H/D Clutch disks, and GYTR H/D Pressure plate. He is pretty good hopefully he'll get part #s. I'll post when he gives them to me.

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??

Ok, so today I went back down to the yamaha shop and we called yamaha directly from the shop. After talking to some guy for about half an hour we got redirected to some other guy. He said he was the manager of parts customer service. Talked to him for about an hour and finally he told us that there are part numbers for it, but they are not selling the pump components yet and they do not know when it is going to be available.

This blows now I have no way to get an oil pump and I don't know if I really want to put on a big bore kit to just have it seize.

Thanks Justin, keep us in the loop, surley they will start selling the oil pumps seperatly. I sure would like to put on in the KITACO88 BBK ttr50. Maybe one of these people that say you don't need the high volume oil pump will buy their kit and not install the pump and want to sell it.

I am thinking of buying the kit and selling it minus the oil pump and clutch disks. I just don't think that the GYTR kit has enough power. Maybe with the high comp piston and stroked it would go good, but that is a lot of money...

I'm hoping that they have more options available by the time I'm ready to get a bbk. Actually, I'm ready now but I don't have the jack.

I've made some headway today. Not on the oil pump though, but on the Heavy duty clutch and pressure plate! All of the clutch #s listed at the start of this thread are good but the improved pressure plate is not listed. Well the GYTR pressure plate number is XLU-16551-00-00 it costs $85.00.
Also I have a different number for the cylinder head XLU-11103-00-00 and a new number for the piston ring set, 22K-11610-01-00. All other numbers are the same as listed on fist post by jtyam27. The Yamaha GYTR paper that I got these numbers from is dated 2/2006 in the corner.

I'm still giving my Yamaha parts guy a hard time about getting me a pump. I told him that I'm not buying an entire GYTR kit for the pump, thats crazy! He said is is calling back to Yamaha to say WTFO? Everything wears out, how are you supposed to replace the pump when worn? That's the question I keep bugging him about.

Is there a difference between the 06 and 07 kits? There's a kit on ebay that says it's for the 06 only.

I believe it is because of emissions in ca

When I helped my friend install his GYTR kit it didnt come with a pressure plate. Is this just a new thing that they added or what?

Mine came with the new pressure plate and sealed bearing installed in it.

Sounds like an updated kit.

Is there a dyno chart floating around here somewhere? All of the kits seem to make around 6 hp or a little less. What gives with that? How come the 107 kits aren't making more power?

Maybe it has something to do with the design of the head?
