Default Re: The Yamaha 'RX' Thread (with pics)

Hi,
I am in a bit of a dilemma, actually I am really stuck!
I haven't come across any other thread which touched upon the same issue.

I got a new block put in the bike in my home town Jaipur, this block does not have any markings whatsoever, mechanic told me it is a "Supply" block, which is a block sold in the open by the same vendor who sells it to Yamaha, so it is the same quality and performance. Due to time constraints, I had no option but to go ahead with this.

Now that the bike is in Pune, it was not running properly, the first mech I showed the bike to kept saying that the block is duplicate and performance won't come until the block is changed. The second mech did a better job, bike was much smoother and performance too improved but he also said the same thing that the block is duplicate, he also advised that the Carb and magneto coil also be changed, I asked if changing the Carb and Coil will be enough? to this he replied that these will bring in a 20% change but the rest 80% is through the block.

On asking what is lacking in my "fake" block, he said he can only show it to me when he opens the block, he said the block sleeve, ports and material of the block are of lower quality as compared to the OEM stuff. The mechanic is pretty competent. My bike is lacking low end response, like they say it ain't flying.

After all these encounters with the mechs and talking to a lot of people, I feel there is no clear benchmarks or methodologies, everyone says something different, different reasoning etc, only thing common is the huge sums of money asked to "fix" the bike.

Now, following are the queries and options I have:

1.Query: RX engine tech is pretty old, maybe 40 years old, so does original or duplicate make that much of a difference?
2. Query: What according to the gurus, would be lacking in the duplicate block, if it is only the sleeve, will re-sleeving the current block help?
3. Query: Which Block to go for? I have been told that Yamaha stockists only keep Malaysian blocks, there are no Indian made blocks available, based on opinions these Malaysian blocks are not at the performance as the Indian made G series.

Options: Based on Current usage of 2000 KM in a year and keenness on preserving the bike more:

1. Don't do anything - just let it be the way it is, as again based on opinions old things can't be made new hence don't waste good money.
2. Change the Carb and the Magneto coil, see the performance gain and then take a call.
3. Buy the brand new "Original" block for 10k plus Carb plus magneto coil plus some more and spend 20k totally for the Power Take Off feel!
4. If I want to go really genuine, buy a second hand G series block, which is bored out to .25, bore it to .50 or get it resleeved for 3.5k plus Carb plus Magneto Coil plus some more and spend 10k totally for the Genuine Power Take off feel! I feel, looking at my usage this might be serious option.

I love my bike, even though my usage is low, even if the duplicate\fake block is ok, there is this unsatisfying feeling about the whole experience, like my bike is not complete, I want the bike to be 100% mechanically, so every KM I ride, should be the best that an RX can give.

Guys please help!

Not every non-OE bore deteriorates the performance, there are people happy with the performance of those bores (same performance as OE bores)

1. Quality matters a lot than the technology, be it 4 decades or 4 centuries.
2. Ports and sleeves will not be in order. A competent mechanic with knowledge on ports & 2 stroke working principle should be able to fix it. But your lucky stars should be with you.
3. If you couldn't find a brand new Indian spec bore, get a used one and rebore it rather than further experimenting.

VFM solution I must say.

15 years went up. Spent 80rs on a can of silver paint and sprayed up the head, clutch and magnet covers. Passed test with flying colors.

Swapped the KBX caliper for a gold bybre since the piston seals went out. Bybre caliper is worse than the KBX many folds. Sigh.

Hi Guys,

A quick update, an opportunity has come to pick up a very less used I-2 block, running on the standard size piston without requiring any boring, just bolt on. I saw the block myself and was as described, the other option is to pick up G1 block which will be bored to .5 and then fitted.

Cost wise, I- 2 is turning out to be 1k more expensive than the G1, that is I-2 is 4.5k and G1 is 3.5k.

The advantage of I-2 is that it is running on the standard size, so a lot of life in it but I am not sure about the performance, the G1 has the performance but it is already half way through it life cycle.

The understanding with the mech is that only if the Performance improves, will I retain the I-2 block otherwise will revert to my current local block.

I have to take a call by end of the day, with the transplant happening tomorrow.

Need advice on the above, thanks.

Exact same collection as mine, only difference is I have a 100 and a 135 5 speed and I am yet to get my RXZ delivered to me, nice to see the entire Yamaha 2 stroke family under one roof.
