But, Sri...I've 4TL00 printed underneath the cylinder head; this is on my old head. What does 00 indicate? Rx100?

I'll open the existing cylinder head & check underneath this weekend.

True. I would say a lesson taught and in return lesson learnt!


You don't even have to open the head. It is there bang on top. All you need to do is look at the left side top of the bike when you sit on your bike.

Lol
You need to Thank the mech for what you're now. You lost money, but, you got something worth in return - The Experience, The Knowledge. Can you buy it with money?

Really? This is news to me. I'll open my head sometimes this weekend & keep you posted on the updates here.

It all began last year June/July when I was cheated badly. I was robbed of bore kit + Head (just got to know) and 3k in cash. God damn! I got reminded now which I hate to remember that incident. I had gone through sleepless nights for weeks after knowing the bike did not sound like how for the past 11 years. Somehow did not like it at all so took it to Y.A.S.S and found out the truth. Big time robbed. Since I did not have proof (nor technical knowledge) could not go fight, but went to him and said that I did not like the way it is set up. I was consoled that 'after couple of days you will start liking it'. Cursed myself for being a victim. After some calls across the city, Thank God, one of the dealers had a bore kit and was lucky to get it fixed (don't ask me what happened to the old bore, I did not take it with me ).

Then no turning back. Started to search the internet to learn about my bike, ah! xbhp.com and here I am. Sorry, I could not resist writing the reason behind my question the Head.

Please let me know about the head. By any chance would that be of RX100?

You could have coined with better word 'robbed' than 'played'. Aargee, I had a look at the new head plonked on my bike. It does say 4TL5 on the top side.

+100000000...
No matter its Rx or non Rx, all mechs are unreliable; its purely because they belong to that segment of the society. One of the top mech in Chennai, who used to be expensive affair does the same, atleast that's what I heard from people who used to give it to him.

sad yaar specially mechanic's cheat big time RX lovers as they know a person riding an RX will never go for another bike,its always good to know your own bike inside out atleast the basic this surely helps in alot from getting cheated .
I always do all the basic works almost all the maintenance on my own only carb cleaning,clutch setting,brake shoe change i give it to the mechanic that too i get it done in front of my eyes when he is sitting idle and has no work so that he has no excuse to give me(i have 3-4 bikes for servicing)

You mech might've played.

I couldn't understand; are you saying 4TL5 will be embossed in the cylinder head in addition to cylinder? But, how're you saying this is a fake one?

4TL5 is mandatory for 4-speed head, this one is a fake. I will just confirm this again as my 4-speed engine is dismantled & i will go & check and click some pics & update.

I just recall one such incident when i was doing my PG. One of friends had purchased an RX135 4-speed (2004) brand new & he too was more of a addict to 2-Ts (He had a KB100 previously & upon persuation from my end he ended up purchasing RX135). He was against porting & stuff & hence we decided to upgrade to 5-Speed bore (4TL10) & he was quite happy with the performance after run-in period. I was using a ported 4-speed setup & somehow his bike was not able to match the pickup & top-speed of my setup.

So we finally decided to get this 5-speed bore itself ported. So we went to one of the reputed guys in Mysore & asked him if he could help. He said yes & then we came back in the evening to check the bike. We took it out for a spin to ring-road & boy the bike was doing something like 115Kmph on speedo. Then for some reason we stopped the bike & were looking near the engine & i realized at that time, that the bore has been changed. The mech had replaced the entire new 5-speed bore assembly with a ported 4-speed setup. We knew he had played a dirty trick & hence we went back innocently to him.

The moment he saw us, he asked, "Saar hege ide performance?" (Sir, how is the performance?), we said "Sooper" (Super).

Then in a flash my friend asked, "Bore Porting sakkat aagi madidira, but nanna Bore Kit yelli?" (The port job on this bore is very good, but where is my original bore kit?), the expression on that guys face was simply amazing. Without wasting another second, he went in & brought our 3000km old 5-Speed bore kit. We asked him to fit the bore back & left. The mech was speechless. That was my last affair with him.

Just for the knowledge of guys here, 5-speed bore is extensively used for Autocross & Rally racing here in Mysore. So every Mech wanted a piece of it for himself.

My bike was bought in September 98 and it was manufactured in the month of July I guess.

Guess along with the bore even the head I was conned last year.

Bike cannot have a head which has a head with future date embossed!

I guess its a 99 Jul/Aug make; I could be wrong though, I'll let some experts comment. Also from the looks only few ppl can comment if its 4S or 5S head. I could make out nothing from it.

BTW, when did you buy your Rx? I know its sometime during 99, but which month?

Argee & JD - Here you go. Let me know if anything strikes with this piece of info.

+1; that's why I asked to take the pic of 5/5 little closer.

Coming up...
Discovered a new way to ride an Rx, hopefully that's a feature that's not present even in a R1, Hayabusa or even Ducati 1198S!!!

look at the production date and month on the top right when you look at the underside of the head sri. can you take a closer pic of that?

This is the one which a street mech conned sometime ago last year. I guess looking at this old head, even the head was replaced. So I'm not sure if it ever belongs to RX135 or not.

After joining this forum, learnt a bit about RX heads. They have special denotion with 4TL5 for 4s and 09L for 5s (if I remember correct). However, in this case, there is no such sign. Anyway good that I have kept it aside and using new 4TL5.

Sharing some experience with installing a 90/100 dynamo

17-Wed being a holiday, I took my 2 comp offs on 18-Thu & 19-Fri & had about 5 days in total

First 3 days spent in total...laziness & the next 2 days were messed up with grease, oil, sleeplessness, phone calls, starvation & all the more...stinking

Saturday, I went to get a magnet puller for Rx so that I can replace my stock 12V dynamo to 90/100 dynamo. Got the tool & started the work around 2:30 PM. Meanwhile, I was able to grab a pair of disc pads for my disc brakes. I bought them as temporary measure so that I can prolong my R&D with Gladiator disc setup.




So I started the work on disc setup first as the front wheels were being removed & Rx was standing unbalanced. Took about solid 3 hours as this is the first time I'm replacing the pads & had to learn things hard way!!!

After that, I thoroughly understoood how to rewire back & then removed the clutch covers, removed the stock dynamo & then wired back the connection; then fitted the matching RR unit. I also bugged psycho98 & SriramEfunds for their help in fixing this. Guys, Thanks a lot, without which I WOULD've not been able to fix this.

So after fixing for the first time, the bike starts good, no issues, absolutely fine & I'm super excited; what a damn bright headlight & I could literally feel the heat from the headlight from the simple 35/35W. When I call up these guys, they give me another pointer that I've missed!!! Damn me

So remove once again & fit it back with a different position; boom & Rx goes kaput now. It doesn't start. By now its around 7:00 PM & fully dark, raining & I'm working with one hand as I'm holding the torch in the other.

I remove it once again & fix it back on the previous position & this time again Rx doesn't start, instead there's a burst in the exhaust with every 5-6 kicks. I'm feeling very terrible as I know I've messed up something bad & all the more, I played with something that was done right at first time

I call up psycho98 & roasted that poor soul who was back from office. So again, I remove, fit it in a different position, but again it doesn't start. By now time is around 8:30 & Wifey is giving damn to me & Rx.

Finally I decide to give up & give one more attempt; this time it was successful, however, there was a double beat (sounded like HD; if you're thinking this is insane, but wait...more comedy to be unveiled). So I call it a day & pack up my tools & head to take my first shower for the day (now you know why it stinks) around 10:00 PM; had dinner by 10:30 PM.

Woke up fresh this morning, found there was a small washer slightly chipped at edge. Though it didn't matter, I replaced it, did it slow & meticulously & boom it works fine. Now I'm happy, fixed the cover, gear lever & it starts in 2nd kick. Excellent. I engage the gear & release the clutch and...what the hell ???
