I took the Blata 13 to the race this weekend also. It was running great. Then on race day I couldn’t get it started.. I had spark so I checked compression.. 80 PSI.. DOH! After another racer with a blata bike died and he seemed to be having the same issue we checked his PSI with my Compression tester.. 80 PSI.. Then a scooter racer wanted to check his PSI.. 65! Lol Was my compression tester broke? The scooter was starting and hauling as.s on the track?! I checked my BMS and it was showing 120 when it was showing 170 before I left for the races.. I didn’t know what to think. Maybe it broke maybe its not.. lol

So I just took my time and checked the reeds, cleaned the carb and put it back together.. Low and behold it started! Shot a bunch of gas out the muffler then sounded strong.. I took it for a spin and it started out great then kept missing a beat.. It died but I was able to start it again.. Charged it back to the pit and it was still idling but skipping for sure.. I changed to a 1 size cooler spark plug and it ran a little better but still skipping or bogging just a little.. The scooter racer said he thinks its my coil or ignition something.. When that thing bogs at high speeds its scary.. It has no stabilizer.. It took a little bit to get it started today but I did get her to start and it almost sounds fine on the rack..

I can’t seem to find a clear answer on what the correct Ohms should be and what setting should I read it at? 2000k ya?
The Coil Ohms test shows 5.86 at 200k and 10.80 at 2000k Positive to Cap and Negative to mount hole
The Ohms reading on my BMS are a little lower at the 2000K in the 8.somethings.. But the Same on the Polini 10.8 and 5.8 something.
Cam, U posted in an Old thread..

“On the flywheel is a set of magnets set side by side;-this is called a "magneto"........... they should be clean and free of rust;-so should the pick-up coil............the magnets revolve past the pickup coil;-this passing produces a magnetic pulse..........this magnetic pulse is transmitted to a/c power to power the plug through the coil windings...............theres a certain size air gap between the pick-up and the magnets in their passing to produce the strongest spark;-that gap is the thickness of a business card........................

you can test the coils power output with a digital multimeter................

remove the sparkplug to get the best revolutions for the test....................

set the multimeter to 500 or 750 volts a/c....................

stick the red probe in the sparkplug boot......................

ground the black probe to the engine good........................

pull the pullcord and note the voltage reading while the engine is rotating....................

it should read around 448 volts a/c.................if you dont get voltage thats 448-425 volts a/c;-the coil is bad and needs replacing..............Peace”


I tested the coils on all my Euro bikes and it seems to be all over the place when I pull but when it stops the Voltmeter reads 538 or close on all 3 Bikes. I’m assuming this still good?!

****! I just went down to double check my numbers and is seems my volt meter has malfunctioned.. Its sparking on the display when I pull my cord and leaving perminate marks.. It constantly reads 536 or -1 on all settings.. Oh ****! Not my day, Again! lol

Even my tools are breaking! On a good note! The BMS Rocked it!! That bike is very nice!!

Thanks in advance Cam and EPR..

Wow, and I thought I had problems. Ok, well I wrote the test stuff down, I will need it some day, Thanks Cam2!
I do know that when a coil starts fading, it works cold and then it over heats in a few minutes and shuts down. Your volt meter probably takes the highest or first reading. If you get near the same reading time after time it could be right. I would try it on another meter and see what it reads. Could be bad connections vibrating loose, coil wire connection,etc.
I got some NGK spark plug boots at PB Parts for $3.10 each, there nice going to get some good 7 or 8mm wire and make my own like Cam2 does. My L7 avatar bike has the NGK boot w/ 9mm Acell racing wire modded to fit coil & cap.

I did See these posted by Gera229 in Mexicanos Thread.. Are they correct?



Them tests are done on a cheapo chinese cag coil.....Different coils have different ohms and voltages...Id contact the techs at Blata to see what the coil specs are for their engines...The higher compression watercooled bikes need higher voltage coils to spark the mix efficiently

Ya the wire on the thing cant be more than 5mm thick.. I'm sure a bigger one couldnt hurt! I need to get another volt meter but got work all this week so the pocket bikes are gonna be on hold till the weekend... I might have had a leak in my float bowl and my rubber intake manifold. Reworked things a bit, cleaned the carb again and moved the needle up a notch.. Now it sounds great.. Need a test ride. Maybe my spark plug wire was loose... lol

Ya i think its good.. It was reading similar an all my euro coils.. I need a new volt meter before I really know. I did send an E-mail to Blata and BlataUSA. If I do get the specs I will post them for sure!

Thanks again!

Sounds like you found the problem, the resistance of the wire inside is most important, the out side keeps the spark from jumping before it gets to the plug. The yellow meter is set on 200,000 ohms I believe and is reading .4

So I've officially ruined 3 Volt meters trying to read the Volts on the Blata Coil.. I set it to 600AC on two of them and the last one had a 750AC setting.. Red to the sparkplug cap and black to the Case. It goes real high in the 1000's on the first pull then all over the place the 2nd and 3rd then just reads 1 soon after... Then they wont test anything on any setting.. The last one still works a little, I only pulled like 4 times and it reads about 84 volts from a wall socket.. lol

The Blata does start and sounds great.. I haven’t been able to take it for a test ride yet but not sure what’s going on with the volt tests...

Cam, that Volt test should be AC setting not DC correct?? I'm going to trade one volt meter in and just stick with the Ohms test... **** Blata and Blata USA have not returned my E-mails about the Coil Specs.. Just a little help might keep the sport alive, huh? Thanks again for being here everyone

Forget Blata returning your message, there to high and mighty to talk to us, if you ask about buying a new bike, I bet they would answer,lol,lol. I think my coil is going bad, orange spark, hard to start, has a new plug and breaks up alot, thinking about a real Blata coil for the C1,lol.
I was so Mad yesterday I was spittingnails and sparks coming out of my ears,lol. Tried to put the slick tires and wheels off the Lucky 7 on to the C1 the front wheel on but the rear rim at he center is 1/2" wider and the gear was hitting the frame and the rear brake disc was not going to line up no matter what, Grrrrr!! Glad I bought that tire changer,lol,lol.
So, I ordered a set of Ultra Soft Racing Tires from SP4L for $40 onsale, cheaper than a stock set. The C1 tires will go on the skinny rims and treaded tires that came w/ the MTA2 bike I got from Canada 2 years ago, so all is not lost,lol.

Oh its A/c volts...I ran a set of christmas tree lights off the coil...They lit up bright and started blowing one by one when I revved it up.....The ohms test is a very reliable test next to an oscilloscope...It lets you know the resistance,,,resistance is what makes a coil function properly..If the windings are compromised or faulting to ground an ohms test will find it,,,,,,,,,,,,,

You know that loop on the end of the tester?????????Thats what should of been used to test the wires voltage tension safely

I have an old Sunn 900 car scope unit on wheel w/ a big scope and a small electric scope, but it is for pre 1973 cars and trucks with points in the distributor. Wonder if it will work on this junk,lol??

HAHA! Its always something... Silly Chinese... ;) Good find on the tires.. Where did you get them?? So the tire changer is still working well for you?

Ya it was on AC... I'll do the Ohms test in a just a bit.. I was using the GB (Gerber Bender) Cheapo Volt meter.. No Loop. Not sure what loop you speak of... :rolleyes: Had no clue the thing could shoot out enough volts to fry the meter.. Crazy!

Haven't used the tire changer yet, looks like i have to take the bearings off the rim, which is no biggy. Scooterparts4less, in Alameda Ca., real close to Oakland, on a little island. Look under MTA2 bikes down near the bottom, $16 S/H and $3.50 Ca. Tax, for $59.50 total. Stock ones total was $64+ dollars, and the C1 could use More Grip,lol.

I have a Commercial Electric model # MS8260A that handles 1000volts and a Fluke 179 that handles 1000 volts aswell....

the loop im talking about is my bad...I forgot those pics are gera229''s..............lol

It dont look too good for Blata.............

As far as the tires...Ive yet to use more than heat,a lil dish soap and a screwdriver to get my cag tires off the rim and a lil soap,,heat the tire in the sun and use my barehands to pop then back on...sometimes it takes a screwdriver just to get that lil bit though...LOL

OK...heres the poop...I just got off the phone trying all their numbers and I didnt get through to anyone...i called the directory assistance and cant find a Blata USA in Lauderhill Fla anymore....I even called Doral F;orida swhere I got a random string of numbers and then crappy music for 10 mins............LOL...........so if the plant in Czechelsylvacchia is still there thats the only place i see getting the info from...............Looks like Blata isnt doing so good in the US anymore due to EPA and declining racing..................:confused:

I just went through their authorized US dealers/repair shops list and alot are outta biz,,Especially the one in NY,,I got through to a Blata USA authorized service dealer in Cali named Rooster racing...The guy says hes at his dayjob and to give him a call back in a couple hours...I told him I needed ohms values for the coil....he said no problem....well see soon......:rolleyes:...Theres many ways to skin a cat....LOL

So if ya want Nipples in 2 hours from now give him a call at....If not Ill do it....but let me know so i dont bug the guy twice for the same info....Thanks...

Wow...Were in the twilight zone............or a reverse dimension....LOL

Do you beleive that when blata pulled its pr and authorized dealers aswell as tech info to the public and shut down their phones they pulled their technical online info aswell and theres one guy in the whole US that knows the actual ohms value to a blata coil?..........i cant wrap my mind around that one.....You mean to tell me out of anyone who ever bought a brand new replacement coil has never ran an ohms value test against the suspected failing coil....?,,,,I cannot even fathom that...........:eek:

Its gonna be a process..This guys gonna find that guy and then Im gonna get an e-mail back...............:confused:
