My friend used to have one with a big bore kit i think it was 180cc if i remember rightly and he used to leave my type s civic sitting while on the back wheel 😂 great bikes unfortunately like gold dust now and insurance companies dont wanna touch you because there over the 15hp limit

Amazing! Where did you got the stock ignition curve from? I have a Zeeltronic Cdi on mine and need a save map for the first startup.

@JLMotorsport 2 года назад

Have a look during the video I show it there. But you can get it from haynes handbook.

@jessebrown9046 3 года назад

Great videos bud! I put a 30mm pwk on my 200r with a wr200 pipe and I was wondering what jets to start with? What size jets are you using?

@JLMotorsport 3 года назад

Start with 160-170 and try to lean it 5 points each time.

@jessebrown9046 3 года назад

I'll start with a 170 and plug chop and work my way down if need be, what pilot roughly do you think?, I thought maybe start with 40 or 42

@lizicskabela6096 3 года назад

I use the same pwk carb and it sounds that it could do much more. The power has to load a bit for me. Was there any full throttle with full power? Regards

@JLMotorsport 3 года назад

when you add a carb this size, you are increasing the quantity of air and fuel, so it means more time to burn, you might to increase the advance timing, but be careful, cause advance can eat your piston alive :)

We are using STD intake and exhaust timings as well as cylinder head. Only added 2 auxiliary ports to the exhaust.

Hi mate do you not need woodraff key after advancing the timing as fort it would just turn on crank or come loose and what gains you get from advancing it

@JLMotorsport Год назад

The woodroof key is just to quickly assemble the flywheel. what really holds it together is the conical fitting, if you ever used a flywheel puller before you will know very well what I mean. ( Racing ignitions do not have woodroof keys)

@djCarterboi25 Год назад

@@JLMotorsport oh don’t they I’ve never known that cheers. So what do you gain from advancing the timing more revs?

@JLMotorsport Год назад

@@djCarterboi25 depending on your carb/ cylinder setup you will gain loads more power/torque and revs. (be careful, it can seize your engine)

I have had 4 Yamaha DT125R, an a YZ 250 1991 but in new condition, I would pick my best DT125R, more fun than the YZ ,the YZ was brutal ,x race bike 2 fast and heavy , plus you don’t need to wear boots with a DT R, the older gen was better than the DT X , I don’t know why they changed it

Won't the flywheel just spin as no key?

@JLMotorsport Год назад

The woodroof key is just to make it easier to assembly it (massive production) What makes it to lock in place is the conical taper on the shaft. (if you ever removed a flywheel you will know what I mean)

@Johnwick-vw5ox Год назад

Thanks for the reply. I thought you needed a key. I have learnt something new today. How much does it cost to do the same as what you have done to the dtr?

@BitbartDE 3 года назад

Why not just buy a adjustable cdi and do it that way. Removing the metal piece from the crankshaft to put the flywheel in an other position isn't the most safe way. I saw engines where the flywheel got lose at high rpm and damaged the crank.

@BitbartDE 3 года назад

I mean it still should have lights so why dont you buy a mvt ignition, Zeeltronic

@JLMotorsport 3 года назад

Hi, This is a budget build, custumer doesnt want to spend to much in this project that's why. if we had used a racing ignition we should get even more power out of it. Flywheel key does not hold the flywheel is only there to make ignition timing easy and accurate.
