el süsteemi vedasin siis koos pingeka jne, et oleks egt`le toide ja vajadusel tuled kui plaanis city kruiisi teha v sõita kuhugi trennima ja sis veel killswitchi ja suretus nupu

tegin siis süütepoolile aluse ei oskanud kuhugi seda panna v ei olnud seda kohta v ma lihtsalt loll aga tegin uue

ja polnud täna plaanis üldse töölegi panna aga pidurid said tagumised tööle säde saadud ja mõtlesin, et valan küti sisse ja huvipärast proovin kui ei siis ei hakka punnima ja oleks päeva õhtusse ajanud. Aga panin 3 matsu ja tuksus, NICE! aga siis avastasin et karpa uputab ja jätsin seima
PS: see lenks on lihtsalt et oleks kinni hoida kuskilt ärge sellepärast muretsega! :D:D

sasipundar juhtmetest

aga nüüd märksa parem

ja siis päeva parim hetk kui mu gaasi amort jõudis!! 8) 8) 8) 8) 8) 8) 8) 8) 8) tegemist siis amordiga millel vägapalju erinevaid reguleerimis võimalusi ja toimetab vägahästi ja ikka kuradima kena näeb välja ka, meenutab nata s6 r/t amorti :lol: aga hind oli sellel amordil ka suht soolane isegi peale allahindlust :roll:

aga ostetud täna sai siis: uued splindid, silku tihendid, süütekiilu, naraku silkupea mutrid, laupäeval uuesti sinna siis plaanis karpa väike jama ära likvideerida ja häälestamiseni jõuda! :p :p

heh, Greetz to you to !

sou let`s make a review.

sou i looked forward to fine tune mu beta, but when i arrived to garage my carb started to overflow so i changed carbs to another 21mm oko with see trough bottom cap, sou the overflowing wasnt nomore problem, i started scoot and i revv`d and mu scoot moved backwards, sou the iginition timing was bad, because i use iginition from some chinese scoot and i didn`t match 1:1 so i have to modifi it a bit!

but i got sr-r front wheel need`s to paint ! and got aerox orig. handlebar, i`m so in loved in aerox stock handlebar and fairings, it gives so good driving position and gives me good space to mount gauges :)

so i have some probs with scoot. cant get the right air and fuel mixture. at low rpm it runs lean but higher revs it gets too much gasolin. So i cant get it.. need more fine tuning.

but some good news to, i got my rims painted pearl black, and new tires!
mounted radiator lower because i use bigger radiator than original beta`s.

first race is 23 of may and my beta isn`t running well, so im quite nervous ...!

But to next up!


New Member
so, beta runs greate, perf is good, at first i got suprised and made my beta almost do a flip :L

so breakes have to be aired out and some minor adjustments and practice, practice, practice!

soon pics and some videos

Yellow Rox's wheel in the back & front pink SR wheel are now...

Anyhow, cool scooter, moves quite well too. Tho cylinder could/should be ported further-more.

so first rave is behind me.

Day started at 7.00 am with picking up our scoots and going to final check up to garage i made quick check ride and heard something strange noise from engine attachment and felt quite soft to corner so if i checked frame and found broken subframe attachment, quick welding and off to track.

10.30 was check up everything was fine so freepractise started and i was quite quick at corners but track was full of sand what supermoto had carried to track and thanks to that i found myself crashed at approx. 60km/h auch ..

so i picked up my scoot and my pride and drove to pit

time practise started everything was perf again times where great again scoot worked perfektly untill at the same FUCKING corner crashed again and even worse so again to pit. Got 2. time at time practise but thanks to crash and not driving whole time practise i had to start last. but i hear strange knocking sound from engine 1. race but didn`t gave it lot of attention so start was good again gained 2 positions but suddenly got loss of power and nothing i had no glue what was happening egt showed normal temp to so i drove to pitlane and stopped. i was pissed. so i knew my scoot wasn`t anymore capable competing for first place and i wanted to just collect 15 points for showing up for start and finishing last, but scoot beta didn`t agreed and my engine stopped complitely working so my raceday was over!

But i was happy that i got my experiance and got addicted to scooter race!

so new cilinder is italkit alu ! and 9 of june we meet in latvia!!

some pics:)

and new cilinder
