How to install an HPI 2Ten ignition on a Yamaha RD50dx

[@brucegroom1929]

Great video of a lovely bike. Memories of being a teenager😮

[@VintageGarageYT]

Haha, tinkering around with them is just too much fun 🤣

[@captainflatspot]

11:17 😅👍👍 that feeling is so awesome

[@VintageGarageYT]

Haha it never gets old!

[@nielshermansen3299]

Did you ever get the light to work? I dont know how to set up the lighting cirkuit but it runs fine.

[@VintageGarageYT]

@@nielshermansen3299 yeah lights work fine. Even better than before. You do have to switch to a 12V system. One of the wires (I think it was yellow) is your supply. Connect that to the main wire of the loom and it should work as before

[@M0biUS01]

This video was great. Help me alot. Im building a fs1 with a rd80mx engine malossi 93 cc big bore and hpi 210 and been having the same issue with weak spark when cold. So might try the hpi weight kit.

[@VintageGarageYT]

I was also thinking about that, but I kinda like the fast throttle response. Not sure how much you loose with the extra weight. It ends up starting ok now. And when hot if it doesnt start easily, a push start usually get its going within a meter or so.

[@hamidsuzuki18]

Me too i have 4 yamaha and 2 suzuki

[@VintageGarageYT]

Which ones?

[@hamidsuzuki18]

I have yamaha F5B ,FS1.16J

[@hamidsuzuki18]

And suzuki K50 and A50

[@VintageGarageYT]

@@hamidsuzuki18 Awesome! That's a nice line up you have there. I want to have an RV50 again one day. Used to own one and they are fun little bikes!

Hi thank you for top video. Can you lease show us a link to buy the tool to adjust the TDC? thank you

[@VintageGarageYT]

It's this one I'm using: www.jmpbparts.com/micrometer-sparkplug-hole.html Let them know I sent you 😉

[@eduardodias4661]

​@@VintageGarageYTthank you , i will. Could you please me help me with another question? The site address also has some interesting pieces. I'm asking if you can help make the connection to the lights, horn and brake light circuit. My motorcycle (Gilera Trial 50 - 5V from the same date of this beautiful RD), has no batteries, regulators or other electronic components. It's a rudimentary system I think only 3 wires come out of the actual flywheel and one of them is for the lighting circuit switch or the other two are from the high coil I calculate. In addition to changing the lamps to 12Volts I will have to buy a 12Volts regulator, if necessary, how will I make the connections? Thanks a lot

[@VintageGarageYT]

@@eduardodias4661 12V out of a 70s bike? Are you sure? Stock systems from that era have 6V systems. What colour wires are coming from the engine? Try to get the bike running and grab a multimeter. Usually 1 wire is the power (6V) and one of them is to shut the bike off (usually black). Connect that one to ground and the bike should turn off. Usually (but depending on your bike) the light switch will take the 6V from the engine and when switched on, will comnect that 6V to another wire. Wire those your lights and connect the ground wire on the lights to the frame. You can do the same thing for the horn. I actually have a video on the electricals off this bike on the channel! You can check it out

[@edw670]

@@VintageGarageYT maybe i did not well explain. My Gilera is 6v but if i install the hpi 2-ten Will produce 12volts, correct? That is the reason why i don't know how to Wire the Yellow Wire that is on the. Kit to have lights and horn on the moped. Thank you

[@VintageGarageYT]

Ah yes, if you're using the HPI 2Ten, you will have 12V. So you will have to change your light bulbs and horn for 12V versions. The yellow wire is indeed power for lights and horn. I just connected that to my existing wiring loom where the original power was connected. If you have to make you own wiring, connect the yellow wire to one side of the switch and connect the other side of the switch to your lights. You can test switches with a multi meter to see where it makes a connection in the 'ON' position. Make sure the fittings of your lights are connected to the ground (usually the frame) and these should work. For the horn you can do the same thing. Most switches on mopeds have different connections (1 to connect the power, 1 to connect the lights, 1 to connect to a horn, ...). But that depends on your type of switch. Then connect the wire for your horn to the + terminal on your horn and the other one to the ground.

[@edwardlevett2459]

This is a different engine to the uk dt rd ty

[@VintageGarageYT]

@@edwardlevett2459 really? What's different?

[@edwardlevett2459]

@ at least the cylinder, head and standard stator. Uk one as standard has two coils , your one uses radial coils in standard stator

[@VintageGarageYT]

@edwardlevett2459 I think you are talking about an RD50M these had indeed a newer ignition and different cylinder and head. This is a DX model with aluminium cylinder and head. The M has a cast iron cylinder and head.

[@edwardlevett2459]

How many gears does the Dx have ?

[@VintageGarageYT]

@edwardlevett2459 it's a 5 speed. I think the M also has 5 gears?

[@bluee081]

I have a 1973 Yamaha as1 125 twin . Do you have a link for a company I could buy a electronic ignition. Many thanks

[@VintageGarageYT]

Not sure of they have an HPI for a twin, but I get all my parts from jmpb. They have a great stock of oem and aftermarket parts

[@tonyiversen5737]

Hello i wonder it this kit fits on a Yamaha DT 125 MX 1981 ? or if you can help me ?

[@VintageGarageYT]

The 125 is a bigger step up. I know the rd shares its ignition with dt50 and dt80, but I'm not sure for the 125. Is there no specific kit for the 125 from hpi?

[@Endrjo]

Is it good? I mean the HPI? i was thinkig of installation for rd250 with points.

[@VintageGarageYT]

I like it. Picked up power over the entire rpm range and gained a lot of throttle response. Not sure if the difference will be as big with a 250 though.

[@Endrjo]

@@VintageGarageYT probably it should be too. ignition time is always the same with CDI. How did you solved problem with hard cold start? It was related just with choke on/choke off? Did you installed DC rectifier to charge battery or it works in AC mode? DC always produce stronger spark.

[@VintageGarageYT]

@@Endrjo On this bike the power on the spark does not go through the battery. Straight from the coils. So currently not running with a battery and/ or rectifier. CDI timing has a curve instead of being fixed like points. I also got a CDI with 2 curves, but have not got around testing it.

[@blackstephill1882]

Would this work on a rx115?

[@VintageGarageYT]

That's a good question. I'm unsure, don't really know those bikes. It depends on the type of crankshaft they have.

[@jimmybrouwer2744]

Hele goede video, alleen wel erg slechte reklame voor jmpb haha. Blijf zo doorgaan!

[@jimmybrouwer2744]

Hpi bedoel ik natuurlijk ook

[@VintageGarageYT]

@@jimmybrouwer2744 Tja ik zou het geen slechte reclame noemen. Blijkbaar werd een hpi echt niet veel op een DX motor gemonteerd. Op de gewone RD zou het plug en play moeten zijn. Ze hebben me allesinds goed geholpen om te zoeken naar een oplossing.

[@Pyroteamdutch]

@@VintageGarageYTpast deze ook op de yamaha dt50m? Zonder aanpassingen?

[@VintageGarageYT]

@@Pyroteamdutch Ik denk van wel. Als ik me niet vergis heeft de dtm hetzelfde blok als de rdm? Dan zou het moeten werken.

[@karthikdattagTEI]

Sir could you explain more or perhaps a link to use the Spark Plug Micrometer? Excellent video by the way.

[@VintageGarageYT]

Thank you! This is the one: www.jmpbparts.com/micrometer-sparkplug-hole.html If you do buy there definitely let them know I sent you! How it works: Rotate the 'top half' to the middle of the threads and loosen the screw that holds the center shaft. Rotate the engine so the piston is at top dead center. The center shaft be pushed up a little by the piston. Tighten the screw again so the shaft is fixed. Then rotate the engine until the piston is behind top dead center. Then you can rotate the 'top half' section. It has indications on there. 1 full rotation is 1mm. So you rotate the top half piece 2 rotations inwards. Then rotate the engine until the piston hits the center shaft. That's the point where you have to put the rotor on. Let me know if you further questions! 😁

Hi friend

[@VintageGarageYT]

Hello there and a merry christmas! 😁

[@Struth_Mate]

Be warned hpi ignitions can come with issues and little to no help will be given from the seller. Do Not expect a refund if it fails to work at all

[@VintageGarageYT]

Jmpb is a reputable seller and I have never had any issues with them. If a part was bad before they've always handled it correctly in the past. Can't speak for HPI themselves though... Did not have any issues with the unit, but I do know cooling is very important for them. Most failures are due to overheating

[@Struth_Mate]

@@VintageGarageYT Good to know your seller is honest and should be pointed out as you have. No heat issues for my problem just a faulty unit out of the box. Seller (official dealer) was reluctant to assist with help initially then refused to repair or replace. good to see you had good luck with the unit.

[@VintageGarageYT]

@@Struth_Mate oh that sucks. You got it straight from hpi themselves? Weird how they refuse to replace it. I even think they have to by law (warranty and such)
