Since I do not have Workshop Manual of RX135, I'm completely deceived by irresponsible Yamaha Motor India for adopting double standard.

I meant you bought a RX 135 4 Speed? Great! Congrats

I have seen it in the manual before. it says 7hs in the five speed manual. And on stock setup there are no heating issues so don't worry

I run an Original 8hs on my stock setup and it feels quite different from a 7hs but Can't say if better. So i have reverted to 7hs.

Thanks for the clarification. So my understanding is there is nothing wrong except cold start and slight difference.

Though going to take the above suggestion to use 7HS, still I'm going to give a try and see what exactly happens for a day or two.

My bike starts on the second kick with the choke.(with the 8HS). No cold start issues faced by me thus far.

The reason I am not using that plug is that I can't be sure that its making any difference to performance or heating/cooling - it feels a bit different thats all.

But its worth a try - you know, just put in an original 8HS and see if you feel any difference ....

Still wonder where it is written that 4 speed - 7HS? If you can direct me to some source of information would be much appreciated.

Says 7HS

I've the same issue, nothing more, nothing less. I was always attributing it to the flat slides & stock air filter. I'll give a check on the plugs & give an update here.

Meanwhile, keeping the disc brakes setup aside, I'm planning to change the front sprockets to 15 tooth from the existing 16 tooth.

Existing - 4S cylinder,head + 5 Gears + 16/34 sprockets
Proposed - 4S cylinder,head + 5 Gears + 15/34 sprockets

Has anyone tried this? I'm assuming that the pick up will become a little sluggish, not sure to what extent. Hope with the new setup, it can still take the Yercaud, Yelagiri hills. And yes, it should give a good top speed isn't it?

**SriramEfunds** · 09-05-2010, 05:39 PM

Thanks for directing me to the parts catalog and I see that it has 7HS

.
Only wonder if that was also given when bought the bike from the showroom

This makes the Owner's Manual futile and as a lay man for many years believed 8HS is the right plug for the bike. This also proves that one is a stupid to refer Owner's manual where there are other sources of information which contradicts with each other.

Keeping the basic information in mind from Owner's Manual seem to be very dangerous I suppose

. You end up doing something other than recommended by various versions of right information. Well, if need be, might have do cross verification with all sources of information and discuss to arrive at a conclusion of what is correct. Jeez!

Though the owner's manual has become useless, however, still could not resist to attach to this post.

Putting a smaller sprocket up front will increase the acceleration. Smaller it is, the easier it is to gain momentum. But top end will decrease very marginally. At the rear its the other way around. Put a small sprocket at the rear and you lose acceleration and gain top end.

Thanks for the correction. Few months ago, Sri told me to carry on with the 16/34 setup of 4S with 5 gears. Now I begin to feel its way too right with your explanation too.

Ok, let me get to the fact as why I'm planning to change; I see a slight horizonatal movement on the chain & hear a slight "tuck" sound when the front sprocks completes one full circle. So I begin to feel there's something wrong with the sprocks as all other components inside are brand new & nothing to get worn out.

So I thought I'll change the existing sprock in the front as I've 2 of them for Rx100 & Rx135 5S.

Any suggestion on the above "tuck" sound pls?

1. Chain too tight?

2. both sprockets not aligned.

3. fake chain-sprocket set.

Troubleshoot as per yamdoots suggestion. Its one of those things. Better start with the parts itself - where did you buy them ? Are they genuine ? In anycase check chain tension - neither too tight nor slack, and then check for sprocket issues.

Do you hear the sound if you rev up in say 3rd gear upto 60 and then back off the throttle and cruise down the road - do you hear a tick tick metallic sound ?

By the way here is my RXZ ..
