Re: Horsepower blata elite 14 wrs

Hi Javi!

Glad to see you around...
This guy does need really help. He´s a real fast rider but his ride is killing him and his mechanic patience, there´s one trouble after another.
In the dyno test the bike developed barely 9hp and is a pain to find the correct carb setting. Last weekend in a local race the bike seemed fine using a chinese barrel, but not that good is suposed to perform a 12cv tuned engine.
Thanks guys, we know in the Uk these bikes are a bunch and you´ve found the right way.

Cheers

Re: Horsepower blata elite 14 wrs

i've tested a stock wrs engine with a 19mm carb on the dyno, it had 11hp at the rear wheel.
the biggest flaw in the blata engine is the intake. you can surely increase power by porting the intake.

Re: Horsepower blata elite 14 wrs

where does one find a dyno for these? also what is the top end on these.

Re: Horsepower blata elite 14 wrs

my posting was a little mistakable. i did not use an engine dyno, i used an "amerschlaeger p4" scooter dyno (simulates a load of 95kg).
any "scooter dyno" is good for minibikes. do NOT use a large motorcycle dyno, they'll just wreck the clutch, as the simulated load is too large (150-200 kg).

i don't know the code of the top end. it's a 2006 wrs engine.

Re: Horsepower blata elite 14 wrs

rasputin i'm wondering if you fitted the PHVB carb in that WRS.. is that right?
Did you know if are any differences between the WRS engine and the B1 Kit engine? i have one origami engine in my elite 13, it's a b1 kit engine because it has the PHVB intake but i don't know if has the claimed 15hp or if it's different than the WRS engine.


PD:the bike also have the WRS exhaust and crank

Re: Horsepower blata elite 14 wrs

the 06 wrs engine has been redesigned from the previous years. thr B1 engine is NOT the same as the WRS engine. the new wrs engine has a flat top piston and a race stuffed crank.the cylinder and head is a complete redesign from the old. My WRS stock came with a 17.5 carb. I had the worst time tuning that carb and getting the bike to run right. I fitted it with a 19mil dellorto carb phbg.. after adjusting the needle and putting in a 83 main jet .. it runs like a champ.

Re: Horsepower blata elite 14 wrs

the 19mm carb is a dellorto phbg. bytheway, that's not my bike. i was wondering about the power of a blata engine so i asked a guy to bring his wrs to the dyno.

i don't know much about all the various blata engines. i have a wrs "kit" engine in my workshop, and it came with a 14mm phva carb. the code on the cylinder is "11d". as far as i know the difference between the "kit" engines and the normal engines is an additional porting of the intake and piston done at the factory. it's not my engine either, but i can use it for dyno tests...

Re: Horsepower blata elite 14 wrs

Anyway I´ve always heard Blata is crearly claiming not so true top end power. The supposed B1 15hp would be 11,5 or 12 at last.
My friends team purchased two 14wrs at the same time and both engines are different, not the same crank nor piston and other small diffs.

Re: Horsepower blata elite 14 wrs

Thanks guys, i had tested both carbs and the phvb was the best to work.. i was very difficult to adjust but once done the bike goes like hell.
My engine is from a 2005 origami and it has the latest type of cylinder, it's marked as 7c05 but in fact is a B Cylinder (marked at the bottom).. had the standar crank but i changed it a few months ago.
Mccrash the power claimed by blata is at the crank, so it you put the bike at the dyno i would do a few hp less.. the other manufacturers had the same problem, all the power output it's supposed at the crank.

Now i'm thinking to purchase a 50cc kit from savacanada because last saturday the piston bearing cracked and some pieces of metal scratched the piston, head and some little scratch in the cylinder.. so anyone could tell me if that kit is a good choice? i'm wondering if the port timing it's adjusted in those kits..

blata, like everybody else, are claiming crank hp. this means that their engine has 15 hp at the crankshaft. the clutch, the chain, and the tire, waste 25% of that power, so the power at the rear wheel is 11 hp. a "17 hp" polini bike tested on that same dyno had 12.5 hp at the rear wheel.

i have done simulations regarding the bigboring of blata cylinders. they predict only a little increase in power and torque, but an enormous increase in "midrange" power and rideability. the only port that definitely needs modifying is the boostport, the rest can be left "as is".
of course, one can modify the exhaust port to get the same power as the other 50cc engines. but this will turn the engine into a goatish beast, so it's only advisable for high-speed tracks.

that phvb carb, is that a 20.5mm carb?

Re: Horsepower blata elite 14 wrs

interesting, i rode this 2 years ago when my buddie got it and i definitly underestimated it. needless to say after a half hr or so of playing with it, the powerband finally reared up like a cobra striking its prey. i think everybody knows what happens next. since i have got it i have not pushed it that hard. i actually want to figure out where that sweet spot is and try to master it so i can be sure to have all my weight down on the front end. any sugestions?

Re: Horsepower blata elite 14 wrs

The phvb carb is a 19mm and the intake connection is 5mm bigger so blata fits in the origami with a special stuffers in the reeds cage and bigger intake hose. As i said this carb gives more performance as the phbg, the engine runs smoother and have better acceleration in my bike

This morning i inspected the damage of the engine and miraclously there was no damage in the cilinder.. so i will change the piston and the head and that's it until i have more money.

Regards!

I see you are also on a spanish forum.. I also have the PHVB19 on my WRS and having a heck of a time trying to dial it in. What idle & main jet are you using and do you run the Blata cf reeds? Also what is temperature over there.. thanks

The wrs already has the intake ported from blata, at least mine came like that. The only problem that hasnt been fixed from what i can see is the reed lift issue. i added a 10mm spacer to help with this and also to stop the boost port from being blocked by the reed since its covered with the original configuration.

My cylinder has the 11D stamp.

This is my dilemna now, i also have a PHBG19 ds i can use in place of the PHVB19. I know the PHVB has a larger throat but trying to dial it in has been a nightmare. What were the differences in performance you found between the two?

Re: Horsepower blata elite 14 wrs

Here is a dyno sheet from a 46.5cc modded Blata with a 19mm PHVB and a 19mm PHBG carby.
There is also the dyno of the 50cc modded motor.
But the kit used is not the USA 50cc wisco kit.

i know these "factory ported" engines. but for a 19mm carb, the intake remains an "eye of a needle".r
