HI folks, having owned my blata 2.5 since last winter 04 have up till now never actually bothered riding it due to the bad weather etc prefering to concentrate on making small changes to the bikes overall looks ( 6.5 wheel conversion, ducati 916 replica decals, etc ) with the idea off riding it with the better weather off summer 05, ie now !!
so okay engine is obviously brand new, never started up till now, went to start the bike the other day , put choke on and used slight throttle but would it start - nope !! thinking I had flooded the bike as I could smell the petrol, left it an hour and tried again and eventually got it going, left it for ten minutes + just to tick over on the small stand checking on it every so often just to make sure everything was okay and to give the throttle a gentle twist, so far so good !!
eventually switched off the engine and then left it another few minutes and tried to start the bike, no problems started first time !!
two days later go out to the bike and attempt to start her up, used the choke on, choke off , slight throttle, no throttle, but nothing apart from it starting the once for a few seconds before an attempt to twist the throttle resulted in the engine cutting out
tried and tried and tried again but apart from an extremly sore wrist and some blood drawn from my finger the damn thing would not start !!
so okay, know that the bike will run, as I say it was running happily for a good ten minutes plus until I switched it off and when restarted a few minutes later, no probs again.
so honestly think it is down to my starting technique or rather lack off it so can someone please just advise me on what is best to do regards starting the bike from a/ cold b/ warm ?? ie always use choke and slight throttle or choke no throttle perhaps ??
the pull starter ?? is there an easier way off starting it rather than just constantly pulling out the whole length off starter cord only for it to be snatched back out your hand back into the housing ??!! what is the correct method for this and also to try maintain some sort off life with the starter cord etc ??
do the bikes get easier to start once the bike has been run in or even just started a few times from new ?? say this because the way I feel just now after having just an extremely sore wrist , blister and a non starting bike am beginning to wonder if a cheap cag which seem to start a lot easier from what I have seen would have been a better bet ??!!! hopefuly not as in all other ways build quality etc, etc am more than happy with the actual bike.
please someone help me out and restore my faith in getting my blata 2.5 to start a lot easier than I have had over the last few days !!
From experience, Blata 2.5's have never been particularly easy to start and unlike Polini or conventional Blata motors, I've yet to come across one that would ever start on the first pull or start without engaging the throttle, but regardless, the bike shouldn't take more than about 3-5 pulls to start.
Anyway, as opposed to just yanking on the cord, try to develop a starting technique by priming the motor with a few slow extensions of the cord. With the throttle slightly engaged, allow the ratchet wheel to catch one of the pawls and quickly pull, not yank. That's exactly what's causing the starter to choke and yank out of your hand. Never pull that cord with it fully retracted in the starter housing. Ouch!
Are you using a fresh plug and fresh gas? Is the plug getting spark? To check, remove the plug, put it back in the plug cap, hold the bottom tip against the cylinder and give the cord a quick pull. You should see a nice blue arc. Make sure you're holding the plug cap as opposed to the actual plug or else you'll be shocked.
I'm sure others will chime in with more starting tips.
Yup, what Freddie said. Also, what ratio oil/fuel mix are you using? As mentioned, your plug will tell you what is going on as far as spark and fuel delivery (Plug color). Good lluck!

Thanks for the informative replies guys will hopefully prove very helpful !!
the engine as I say is brand new so yep the spark plug is obviously new and unused itself.
using a 30-1 mix of oil now and was going to go for a 50-1 mix after running in ( 5 tanks ) correct??
arm / wrist is still to sore to even attempt to try the starter cord again today but will certainly have another try later on in the week using your advice regards the technique for the pull starter cord pulling.
will leave it at that but any further advice / tips from anyone else would certainly still be very much appreciatted.
Im assuming that you have a stock 1412 carb with a manual choke right? My best method starting my 2.5 with a 1414 carb with automatic choke is:
Cold start: choke on, throttle held just before it slightly releases the choke, short quick burst pulls. Usually starts on 3-5 pulls. I then rev her up at 3/4 throttle to release the choke and to feed in more fuel.
Hot start: choke off, 1/4 to 1/2 throttle held, also short quick burst pulls. Usually starts on 1-2 pulls. I then rev her up again.
If my 2.5 has one of those days when its on a rag, I bust out my can of starter fluid and 1 or 2 shots sprayed into the intake will start her right up! Never fails! But I use the starter fluid minimumly. For really hard starting, I also take out the spark plug and spray a shot or two into the cylinder spark plug hole.

Personal preference, but I've broke-in every bike I've owned at 50:1 for a tank or two and honestly, there's really no reason to use that much oil in your mixture. Aside from a few fouled plugs, it's not going to hurt anything, but again, there's really no point.

Okay thanks again guys for your continued help it is much appreciatted, have just gone out to the bike tonight and using all you guys kind advice regards starting etc managed to start her within the first two pulls off the started cord and all without starining my wrist !! so certainly a lot lot happer now
did notice that whilst the bike was sitting on its small stand with the engine running away ( no choke on ) that the bike was getting kinda hot, is this normal ?? ie you could feel the heat from the engine comming from the bike, and the sides off the fairings were warm to touch, also slight smell comming from engine - new engine so again perfectly normal ?? - certainly hope so !!!!
rear wheel was also slowly turning on its own under no throttle ( normal again ?? ) obviously upon sitting on the bike the bike would not move unless throttkle was applied.
lastly !!! any tips on mixing up the fuel at the 30-1 mix and also 50-1 mix levels, want to idealy put the exact required amount off oil in the bikes tank and then top up to the brim with petrol, but obviously need to know exactly how much oil to put in the tank first ??
if this is possibly not a good suggested idea for mixing ?? any other oil / petrol combinations that woukld make it easer for me to work out how much off each to add together again for this 30-1 level and also 50-1 level ??
I'd go with the 50:1, also adjust your idle until the the wheel just stops spinning (making sure that the motor does not die out). Your clutch is engaging because the idle is set too high.

Use a Ratio-Rite cup for mixing the gas and oil, which you should be able to find at a cycle shop, auto parts store or hardware store that sells lawnmowers, 2T oil or 2T machines.
Also, it sounds like you're talking about pouring the oil directly into the tank and topping it off with gas. In case you are, don't do that. Premix your gas and oil in a gas can.
I feel your pain! Prior to reading these tips, I also experienced the sore wrists, blistered fingers, and a bruised arm (exact shape and outine of the pull handle) from letting the cord handle whack me at full recoil.
want to know how to start it?
i got the answers
check ur spark plug make sure the tip isnt' black
if so go get a new ngk bm6a spark plug
then install it.
then put some new fuel into ur bike
then try pulling it twice half way very slow
then hold down the throttle and pull that thing like a lawn mower and it will start
hey i got a 49 c air cooled bike 4 days agao, it was really hard to start, i had to pull it about 50 times, it ran good for the fist 10 min, but then the coil inside the pullstart (that pull the string back in ) got messed up so i took the cover off and fixed it, i put it back on and started it (after about 50 tries ) it ran really good, but now i cant start it again, i have tried almost all of tips on this forum and it still wont start, does it make a difference if i jsut pull the string a couple time while giving it gas to prime it, or does it HAVE to be done slowly?
if there are any other tips that might help it would be greatly appreciated.
and also, with the starter fluid, can u just get that at like canadien tire, how much is it, and wut should i buy specificly, also does it work that good?? i hope so, and is it har on the engine ( i have very little experience with mechanics)
Blata 2.5's are kinda tempermental. However bullet proof motors.
Did you check your fuel petcock was open? If the lever is pointing parrallel with the motor then it's off. If the lever is pointing at the carb, then it's on.
Also change your plug. If you let it just sit there for 10+ minutes there's a 95% chance the plug is fouled. Letting Two strokes idle for long periods of time fouls plugs. If none of this works. Take your carb out. open the float bowl check your jet to make sure there is no small piece of debree in there plugging it up. You shouldn't HAVE to do this if the bike is brand new cause there is a small filter on the carb But you never know.
I'm gonna almost be sure that your problem lies with the fuel petcock. I bet it's off. I don't know how many times I've done that myself. Or your plug is fouled.
k i checked the plug and its good, i tried the starter fluid thing and i can hear it starting but it wont stay running , it will die in like .5 of a second, should i just spray mnore or is ther anothetr way i should do this ??
Ok You're not getting fuel to the motor. So somewhere it's getting stopped up. You need to check your fuel lines, need to check the carb. Take it off and open the float. If there's not gas in there . then your fuel line is plugged up somewhere. If there is Gas in it. Then check Your Jet. there May be a small bit of sand or dirt lodged in the hole. Take some compressed air and blow the carb out real good. ANother way to tell if you're not getting any fuel to the motor is by taking the plug out after numerous attemps to start the bike. If it's dry there's no gas getting to the motor.
Also check the fuel tank. Did you maybe run out of gas after letting it sit running for the time you did?
Three things that make a motor go.
Spark
Gas
Air
If you know you got spark that's not the problem
If you know you're getting air that's not the problem
If you know You getting gas, that's not the problem.
So check the spark
check the gas delivery
and check the air delivery.
Maybe Your Air filter is bad.
the damn thing would not start !!
so can someone please just advise me on what is best to do regards starting the bike from a/ cold b/ warm ?? ie always use choke and slight throttle or choke no throttle perhaps ??
