CE - Motorcycle Workshop

Okay! Its Official! Its CE Motorcycle Workshop !

How do Crazy Engineers maintain their motorcycles? What do they know about their motorcycles? What do they do to get that extra mile out of each liter of petrol? What did they tweak their bike engine to get that high pickup?

Everything discussed in this thread. Motorcycle fans - drop in 😎 !

Share it with fellow CEans!

Count me in! I think we can start off with discussions on 2 stroke and 4 stroke engine. Without a detailed study of engines, it will be difficult for any newbie to understand his motorcycle.

Nice initiative!

Sure, I think there's a thread which talks about 2 stroke engines. Can we have motorcycle freaks who understad their machines in-and-out to share the knowledge with us?

Dead thread! 😕

I had lots of hopes from this thread but it seems I'll have to wait to see discussions on motorcycles.

I'm sure we have lots of knowledge to share here. Personally, I'm looking forward to learn more about my Yamaha's Engine 😉

CEans!

Hi Navin, I guess we can put the presentation on one of the data servers and put a link to it in the post.

I'll make an announcement soon.

I have a Royal Enfield Bullet which is not much known for its acceleration though handling and stability is legendary. I got 150/80 R15 tyre installed in rear which further increased the handling. I cut of the rear mud guard and made the bike a single seater to lose some weight for increased acceleration. Got another bend pipe installed on the opposite side of the original one and also lost the silencer. Get engine tuned to a high torque. This further increases acceleration. Lost some more weight by installing a lighter handle, getting rid of the indicators, rear view mirrors(this also made the bike more aerodynamic) and some small thing which i hardly used. Got a smaller tail light. Kept the number plate small so that it won't provide much resistance with air while traveling. Some of these may sound very small changes but put together they are huge and are many times the difference between the winning and the losing bikes on the race track.

Expanding on my last post. In this i will discuss ways to improve mileage. A method for increasing mileage is that you always keep your tires filled with air(more than the standard/required value). The less the contact area between road and tyre, the less gasoline the engine burns and when you overfill them, there is only a point contact with the road though the ride quality does go for a toss. If you do not race then the weight reduction on the bike also increases your efficiency. Get your engine tuned to a lower torque and you will find the mileage slightly better(at the expense of acceleration). Keep the normal tires that came with the bike and do not do any thing with the silencer. Drive in the prescribed way for your particular bike without any sudden accelerations. Always use one kind of fuel, if you use a high octane rated one then always put that. Get your bike serviced regularly and keep it clean. Change all the oils regularly in time. This is rather important if you want mileage. Remember, If you care for your vehicle, it will care for you.

Thanks for the tips, Prateek. What should be the optimal driving speed? Or, is there any?

For different bikes it is different. You will normally find it on the user's manual. For the Indian bikes i.e. 150cc and above bikes it is near about 55 - 65 kmph in the top gear.
Slightly less about 50 - 55 kmph for 125cc
Scooters also have the same range as 125cc bikes
All these figures are approximate though and you will have to check with the manufacturer or the manual.

Which bike do you have and what exactly do you want to know about it's engine??

I have the Yamaha RX-Z model ( 5 Speed, 14 bhp ) which was in production for few days.

I don't have much idea about petrol engines, so all my questions will be newbie questions. Could you tell me about 'engine tuning'? What's that and why its needed?

Tuning is the adjustment/modification of I.C. Engine to give optimal performance either in terms of power output or economy.
It includes a lot of things. From carburetors to air filters everything can be adjusted according to your needs. You can search Engine tuning in wikipedia and you will get a lot of information.
Performance tuning is a specialized form of tuning used in racing circuits. I will talk about cars. Here you tune the suspension, transmission, engines, supercharger/turbocharger(in case of sports car) etc to get the kind of performance you want. eg. if the circuit is a lot straight then you may tune it to some of the following specifications:-
Engine Max. Horsepower
Transmission Top Speed
Supercharger Slightly lower RPM
Suspension slightly towards understeer
In case of a circuit with a lot of twists and turns
Engine Max.orque
Transmission Max. Acceleration
Supercharger High RPM
Suspension Slightly towards oversteer
in the same way to get your required performance you can tune tires, brakes and NOS(if you have one installed).
So therefore by tuning the different parts in your vehicle you kind of tailor make it for your purpose.
I have talked about cars here as it lets me cover a wider topic in tuning. Bikes do not have all these parts but the engine, brakes, suspension, NOS can be tuned.😎

As far as street bikes go I have a Triumph 900, Klr 650 and soon adding a sv 650. I do all my own maintenance and modification work myself. As far as the Triumph, it has free flow exhaust, I've removed the airbox and installed pod filters on the carbs, rejetted and installed a one tooth smaller front sprocket. Suspension weaks have also been done plus things for looks or weight saving. The KLR has mainly been modded for travel/commuting and offroad without sacrificing on-road handling. Lots of guards, racks, oversized front disc carb vent line relocation (so it can go in water up to the seat height).
