Hi guys I have rebuilt my rx 135 4 speed. It has got the new bore+piston etc. I was really excited about it's power after having the new bore. But all the dreams went away as I am not getting the pickup and also the top speed.

Infact the pickup in my old bore was much better than this new one

When I asked the mechanic he said it will take some time to get the power as this is a completely new engine. Is this normal ?

Please help me guys !

ken cool

Duly go through the thread on this forum, there are many thread explaining how are we supposed to go through the initial phase of new bore kit.

Can you list out what are the other changes have you done apart from bore kit? How old is the bike? Carb setting etc...let us know from where have you purchased the kit (very important).

Also, have you completed the runnin period?

I'm sure you are aware about the new bore as how it has to be treated, the reason is, if you trying to wrist the throttle with in the runnin period, might as well, lead to some disaster.

Take some note from the engine as to noise, response, settings etc and come out with specific question.

I'm sure you will get support from this forum.

Hey guys thx for the reply. I have done around 200kms with the new engine. It is actually 2000 model. The things like new bore + piston + rings have been changed. Apart from that everything remains the same.

Hoping to get some more information. Thx in Advance !

^^ 200kms on new engine is not worth taking an opinion on pick up and top speed.

Please wait for alteast 750-1000 kms to complete. During this period it is advised to control the speed around maximum 40kmph. Also, you will need to add extra oil on to your petrol tank for better lubrication of piston.

Whether your bike has 2t oil pump functioning or premixing,would advise to add extra atleast 30ml of 2t oil along with petrol.

Initially your bike will smoke bit more than you could imagine, relax, it is normal, remember, the extra oil that is poured in would make the engine smooth and would prevent from any scratches or seizure. Offcourse if ain't smoking, it ain't 2stroke (I'm sure many would agree )

This would also, help in getting the engine set right. If the initial period is screwed up, then you might end up having a problems due course of time.

Once runnin period is over, then check if the pick up and top speed.
Hope these pointer would have some help to understand and take precaution.

Seniors: - Please add your valuable suggestions and correct me if I had missed any major point.

Thx for the reply. I really appreciate it. To be frank. I have touched the 60-70kmph speed with this new engine once when I was travelling on highway and I didn't know anything, but now I think the bike is little better now after 200kms. Also regarding the smoke you said, I am not getting any smoke and I am premixing oil with petrol directly.

SriramEfunds

^^ not able to understand your message.. Are you saying the problem is solved?

Touching 60-70kmph, is not advisable during running period.

You were not able to see smoke? Then something is wrong, better check if the 2t oil premixed is optimum. As everyone in this forum would agree that bike should smoke atleast to an extent, and your muffler end should show signs of oil on the outer.

No what I said was the acceleration is sometimes Ok after 200kms as I get quick response from the new engine. But many times I don't get the sudden pickup as a rx135.

Regarding the smoke. I was not their when the bike was rebored. My dad took care of it as the mechanic is my dad's friend. My dad told that the mechanic after reboring started the engine and allowed it run for quite some time for the rings to take seating positon. I don't know whether it smoked during this time. But now I am not getting any smoke from my bike

SriramEfunds

I thought you said it is new bore + piston? Now I read your post saying it is re-bored?

We reply to the issue based on what has been posted, unless you come up with accurate information, you might not get proper solution or guidance and it would be just a waste of time.

Also, not sure if you had posted your intro in 'Who are you' section of this forum. If not yet, kindly do so.
