Hey Nithin, Here when I was searching for butterfly crash guard here all I could find was the one which is slightly smaller in size. In your RX100 I have seen the crash guard looks neat with correct size. And I think its a newly purchased one...If yes, Is it a original part from Yamaha? and please share me the shop address from where you got it.

**NitinGirish** · 01-03-2012, 08:43 PM

OE crashguard was put to rest long back. Had two falls while I was learning (Std.9).

The crashguard currently on my RX100 was sourced by my then mech who also did the 135 restoration. Don't know where he got it from (somewhere from South Bangalore I guess) and I never again want to speak to him in my life. His contact details though, is available few pages back.

Thanks Nithin for the reply, I thought you bought it recently..

I am facing a weird issue with the bike. After riding for 12-14kms bikes shuts off. It jerks like as if petrol is over and then shuts off. Need to start it with choke on, nowadays with only two kicks.

What I cannot understand is that, it happens ONLY during my evening commute. This has NEVER happened in the morning. Also, this happens only after I ride a minimum of 12kms.

Not sure what could be the problem. Most probably I will get 1000kms service done this weekend. Any pointers I should keep in mind for this issue while speaking to the garage?

**kb100** · 01-04-2012, 08:45 PM

probably vapor lock in the tank, try opening and closing the filler cap when it shuts off

**NitinGirish** · 01-04-2012, 09:18 PM

Vapour lock only in the evenings?

**aargee** · 01-04-2012, 09:33 PM

Nitin - Where do you park the bike all day? Cool covered parking or outside in a shade? Like KB100 says, its vapor of petrol probably.

Just remove the rubber cover underneath the tank cap, clean it well, also ensure that the hole is cleaned up + there should be a cork that will be visible when you remove the rubber cap. Just make a good hole on the cork (never mind, the fuel will not spill out). This will take care of vapor, daper or anything.

**NitinGirish** · 01-04-2012, 11:18 PM

I park it in cool covered office parking lot. Will get the tank cap cleaned on the underside and report here.

One more piece of information I forgot to give out. My dad experienced the same problem occasionally but that was before the rebuild. Wonder what problem it could be that survived a complete rebuild!!!!

**NitinGirish** · 01-19-2012, 08:49 PM

Evening blues seem to have gone away. Pierced through the cork seen in the breather hole. Ever since doesn't get switched off.

1200kms up. Still haven't given for servicing due to tight schedule on weekends. Most probably 1st week of Feb.

Oil pump seems to have failed. In 1200kms, only 30% of oil has been consumed. Thank God I've been using pre-mix also.

Plenty of niggles in the bike. Hoping to get everything fixed in the 1st service.

hmmmm yes, make sure the dot mark on the disc has been aligned with the pulley.

Strange to know that the Oil Pump has failed Nitin...Cos in my bike the Previous owner ran on auto-lube only for 1st 1k kms or so and then on pre-mix until 66k kms & till all the way the oil pump continued functioning dry & seems to be still pumping up healthy until i decided to open-up & replace for my own satisfaction...Also speaking of pumping up low volumes of Oil, has the pump been calibrated?

I'm not surprised. Even I had a new oil pump failure in 1000KMs. Ever since I've gone premix.

You say 30% oil is consumed, then how can the pump fail? The oil flow rate is directly proportional to the throttle opening. For the first 1000kms i assume you will be in 2500-3000RPM band. Its quite common.

I do WOT runs & oil gets almost finished when the odo has run 1000Kms. Also you can control the flow rate manually also. Just needs the right tuner to do it.

By the way did you check the procedure mentioned here:

xBhp.com : The Global Indian Biking Community

http://www.xbhp.com/talkies/thumpers-two-stroke-exotics/17834-frequently-asked-questions-yamaha-rx-series.html

10. How to check if the 2-T oil supply pump is working or not ?

Ans: The 2-T oil is supposed to mix with petrol for combustion & it helps in lubrication in the cylinder area. Inadequate supply of 2-T oil can cause major siezure of the engine, sometimes even with crank bottom siezure. It is very essential to have a track of this 2-T oil flow periodically. This is the procedure:

a. On the LHS of the bike (Gear Shifter Side) we have the 2-T oil tank, which can hold approx., 1.1Lts of 2-T oil. There is a peep view available for RX100 (It even has a guage), RXG, RX135 & directly looking at it will give a fair idea of how much oil is present. You may want to bend the bike as well to check if the level is enough. For RX-Z there is a oil level measurement & indication on Tachometer for the same.

b. Now we know that there is enough oil in the tank, but how to make sure it is flowing & doing its part. There is small 2-T oil pipe connected on RHS of the carburettor assembly, you should disconnect this pipe after the bike start up. Keep revving the throttle & wait for the oil to ooze out, if it doesn't even after say 30 secs, then there is something worng either with the pump or there may be some leakage with the pipe or vacuum in the whole system. Get the bike checked with nearest service center & get it get the problem rectified.

c. If you are in the middle of a trip & something like this happens, kill the engine, let it cool down & drive very slowly to the nearest petrol pump, go for an oil mil for around 3-4% & then proceed.

d. On a long trip, you may always want to use around 2% oil mix with petrol (Shell bunks have these facility of direct mix) just to be on safer side.

Sorry i beg to differ here, i have been using Synthetic Oil directly via pump & use additonal 2% mix for Highway rides premix available at Shell Bunks. Till date i have not faced any siezures or spark plug failure or any other adverse effect. Do it your way, we are here only to suggest.

The owners manual doesn't say anywhere to disconnect the pump during run-in period & then again connect it back!!!!!. Trust me i have run-in more RX135 bores than you people can ever imagine for the last 10+ Yrs.

You got me wrong Karthik, the previous owner was in his own mind of using the Auto-Lube only until the can of oil lasted after he took delivery from showroom & then switched over to Premix till 66k kms during which all the way from 2000 kms - 66000 kms the pump continued functioning dry & when i switched over to Auto-lube after a general service & check-up of the pump, it still continued functioning great. I was just vouching for the quality of pump made & to my knowledge i've seen only a very few pump failures due to shaft problems..
