    This is one helluva thread with the most suited title.
    Hot-rodding, Big-Bore, Loud pipes, seizures, Re-installations, savings and what not. Subscribed long ago & following quietly since then!!! - Good for us that you show up despite your busy curriculum.



    Keep up the work & enthusiasm, mate! Kudos!!!

    I have been through your complete experience and can only express my sympathy for the hell you have been put through. Honestly speaking, this is not the kind of support (add 2 gaskets and call me in the morning) I expect and would be willing to put up with.

    Some where along the line, the gentleman who is supplying these parts has either lost his way or has started cutting corners. The attitude seems to have changed from 'I stand by what I sell' to 'Don't call me, I will call you'. A sad ending to a very promising story.

    I am not a expert in 4 strokes (nor was I ever an expert in 2 strokes for that matter). My first 4 stroke was bought in 2009, and I started working on my bike in 2010. Therefore, I am very raw and new to 4 strokes when compared to seniors like PSR. When I think retrospectively, I KNOW that I had the beginners luck, when I got my first engine build with the 165cc big bore right. I did it without any measuring tools and without any application of 4 stroke knowledge. However, it is a given that Mr. Murphy will strike one day and it is inevitable.

    The whole response; 'add 2 gaskets and see what happens' is like being blindfolded and then being asked to pin the tail to the donkey. What are the chances that you will get it right? 1 in 1000? 1 in 10,000? Engine building is a science and not a pin the donkey game.

    I am sure more knowledgeable people like PSR will give you better advice, but here are a few pointers from someone who is still learning:

    1. First of all make sure you/ your engine builder has good measuring instruments including vernier calipers, dial gauge, micrometer, compression gauge and feeler gauge.

    2. Secondly make sure you/ your engine builder has good set of tools including a good quality torque wrench and impact driver and socket sets.

    If your engine builder does not have the above (and use them), my advice to you is 'get the fastest horse you can and get the hell out of Dodge city', because these type of failures are going to be recurring part of your story.

    3. You should also have your bike's workshop/ standard manual at hand (all the torque values for various fasteners is the bare minimum you will refer to). Though standard clearance values and tolerances will be a benchmark for your build.

    4. As far as your engine build is concerned you need to measure not just the compression, but you need to go through a process called 'Decking'. While the process of 'decking' is too long for me to put in words over here, the bottom line is that there needs to be enough final clearance between piston-to-head (thus you require measuring instruments). One of the reasons this is very crucial is the fact that when a engine is operating at high rpm, the piston will tip sharply at the top of stroke i.e. when the crank will stop pushing the piston upwards and begins to pull it downwards. This phenomena will cause the piston deck to move towards (along the thrust axis) more closely (remember that the connecting rod will stretch and flex at high rpm thereby changing the actual final clearance between piston to head). Under such circumstances if the piston accidentally taps the cylinder head, the top ring groove can collapse and the piston ring can get pinched leading to compression loss.

    The above is just one of the effects if the tolerances are not proper. While assembling the engine you will need to check all the tolerances vis-a-vis stock and decided if they are acceptable. Check and re check every single item, its fitment, tolerances and clearances. You don't need to rush the build, you are not in a race to see how quickly you can finish building the engine.

    I hope I am not offending anyone, I am just giving a few words of hard earned knowledge in the most humble manner possible.

    Abhimanyu....It was kind of you to think of me as a senior member with useful knowledge..
    Like you had mentioned, any one with acceptable level of knowledge ,and having worked with proper tools will never commit the kind of mistakes, and bad engineering seen on the destroyed BB kits..Adding Gaskets is an old trick done for a stop gap working and is never a solution...I had advised a fellow biker of the same almost 2 years back when he had tried to do a BB mod himself, on a Fiero, and landed up with severe knocking...later the trouble shooting was done properly and the member had solved the problem...

    There seems to be no standardization ,or quality check..the so called "Semi Forge" piston is nothing but a cast piston which easily goes out of shape and either leads to seizure or shattering...
    Hope members thinking of Hot rodding are wary of the pitfalls,and take wise decisions .

    No intention to hijack this thread, but just sharing my experience of hot-rodding- http://www.xbhp.com/talkies/help-me/...heating-1.html
    I have been through the same experience on my souped up R15. I just want everyone to know the pros and cons of hot rodding and than take an informed decision. Most of the times, we just get to see 'One side of the coin'.

    Juris.....What a painful and shocking experience you have gone through.You have high level of patience......Hot rodding material and work done by people without proper knowledge, commitment or tools is a recipe for disaster....Good to know that you are now on stock setup .
    Good Luck...
