Gutwara abafana ni ubwoko bwo gutwara, bivuga ubwoko bwo gutwara bwakoreshejwe numufana wumuriro ukonjesha ikirere.
Mubukanishi bwubukanishi, hariho ubwoko bwinshi bwubwikorezi, ariko hariho ubwoko buke gusa bukoreshwa mubicuruzwa bikoresha imirasire: ibyuma byamaboko ukoresheje guterana kunyerera, imipira yumupira ukoresheje ibizunguruka, hamwe nuruvange rwubwoko bubiri.Mu myaka yashize, inganda zikomeye zikoresha imirasire zashyizeho uburyo bushya bwo gukoresha ibyuma bifata ibyuma bifata ibyuma bifata ibyuma bifata ibyuma bifata ibyuma bifata ibyuma bifata ibyuma bifata ibyuma bifata ibyuma bifata ibyuma bifata ibyuma bifata ibyuma bifata ibyuma bifata ibyuma bifata ibyuma bifata ibyuma bifata ibyuma bifata ibyuma bifata ibyuma bifata ibyuma bifata ibyuma bifata ibyuma bifata ibyuma bifata ibyuma bifata ibyuma bifata ibyuma bifata ibyuma bifata ibyuma bifata ibyuma bifata ibyuma bikoresha imashanyarazi..Imirasire isanzwe ikonjesha ikirere ikoresha cyane amavuta yatewe amavuta hamwe nudupira.
Amavuta yashizwemo amavuta ni amaboko akoresha kunyerera.Amavuta yo gusiga akoreshwa nk'amavuta yo kugabanya no kugabanya gukurura.Mugukoresha kwambere, urusaku rwo gukora ruri hasi kandi ikiguzi cyo gukora nacyo kiri hasi.Nyamara, ubu bwoko bwo kwambara bwambara cyane, kandi ubuzima bwumurimo burarenze kure ubw'umupira.Byongeye kandi, niba ubu bwoko bwo gutwara bwakoreshejwe igihe kirekire, bitewe nimpamvu yikimenyetso cyamavuta (ntibishoboka gukoresha kashe ya peteroli yo murwego rwo hejuru kubicuruzwa bikoresha imashini zikoresha mudasobwa, mubisanzwe ni kashe yimpapuro zisanzwe), amavuta yo gusiga bizagenda bihindagurika gahoro gahoro, kandi umukungugu nawo uzinjira mubitereko, bitera umufana Umuvuduko ugenda gahoro, urusaku rwiyongera nibindi bibazo.Mubihe bikomeye, eccentricité yabafana iterwa no kwambara bizatera guhinda umushyitsi.Niba ibi bintu bigaragara, fungura kashe ya peteroli kugirango ushiremo lisansi, cyangwa ugomba gukuraho no kugura umufana mushya.
Umupira utwara uhindura uburyo bwo guterana kwifata, ugafata ubwikanyize buzunguruka, ibyo bikagabanya cyane ibintu byo guterana hagati yimiterere yabyo, bigahindura neza ubuzima bwa serivisi bwabafana, bityo bikongerera igihe cyumurimo wa radiator.Ikibi ni uko inzira igoye cyane, bigatuma kwiyongera kw'ibiciro hamwe n'urusaku rwinshi rwo gukora.
