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.
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've made some headway today. Not on the oil pump though, :sad: 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 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?
Hi im from the uk and i've bought masso'S ttr 50 now ,but it's fitted with the 2 bros 107 kit and various other bits and peices two bros say that the 107 kit they sell does not need the hd oil pump and hd clutch part's is this true as you cannot get part's for the ttr 50 in the uk from YAMAHA as they dont sell them here which suck's .Can this thread be updated as to what part's you have used and fitted as i will be very intrested in what you guy's come up with for youe bike's...thank's BUZZ

Not to be rude, but we are trying to use this thread for listing part numbers for the ttr 50. But nice bike none the less. There is another thread with everybody's bikes specs.
Those are the numbers that are on the part breakdown that comes in the kickstart kit. I had a problem with the gytr oil pump part numbers, yamaha said that they didn't exist, then after a while, they were like we cant get these, then all of a sudden there was a new number they had for it and wella!
I'm enquiring about a custom rev box for the ttr 50 tomorrow as there's a guy in the uk that make's reprogrammable cdi rev box's for most bike's..here a breif description of what it does...
"The cdi he makes is the "Twinspark" it is fully programmable..it comes with 5 user selectable curves which give various degrees of advance up to the maximum advance which is governed by the position of the tab on your engines rotor.
To ease starting (i.e prevent kick back) the cdi retards the ignition until the engine fires.
It's main feature is the cdi fires the spark plug multiple times to promote a good burn. Hence "twinspark" At tickover the cdi is actually firing the spark plug eight times, this reduces as the engine revs up, at 3,500rpm there are six sparks, up to 7,900rpm there are four sparks and 8,000rpm upwards there are two.
This helps to prevent the stutter when pulling away after idling for a while, which you can get with a stock cdi. The engine feels generally a lot smoother and pulls a lot better (as someone mentioned) with curve 3 selected. TJR have one fitted in their 180 race bike which Chris made some custom curves specifically for with Michael.
They reckon they're getting an extra 10km/hr out of their motor as a result.
Attached a photo. The three blue blocks are the high voltage capacitor bank. The BNC plug is what determines which curve is selected. (The cdi beeps the curve number so you know)
They work on chinese engines as well. The cdi needs a +12V supply from the battery (ideally from the ignition switch)
If you have a Honda wiring loom, this might have the rounded type of cdi plug fitted. That plug would need to be replaced with the squarer chinese style plug.
You can get the correct plug from Rovaza NL, (Welkom to Rovaza) contact Rene, part number 400034P (CDI Plug)
