Universal Electric Turbo Supercharger thrust motorcycle air intake kit.
Well I have been wanting little extra go for my gc190 mokai to get up bigger rapids and to outrun the odd rogue wave,this maybe answer.
Can buy off ebay world wide whether you have Honda robin or Subaru these look promising I shall certainly be trying for sure.
have been looking at many engineering fixes for the Honda then stood back and looked at big picture have already solved engine power loss due over heating through cold air intake air venting rear of air intake for better airflow free flow exhaust gx 200 no.72 fuel jet and higher grade higher temp 10w60 oil the 10 relates to viscosity or thickness of oil and the 60 relates to higher temperature lubrication of the upper cylinder head also I use nana energizer oil additive for small engines.Thought build piston balance conrod and lighten etc.
Then i thought air scoop then supercharge.
Researched for5hours and the universal electric supercharger for small engines is the bees knees.
Cannot see any logical reason it wont work for me as only want bit more pace to attack bigger rapids although honda has no electrics for short bursts small battery probly do i go for a litium starter battery well its been fun i let ya know how it goes in couple of months gotta order it yet hahaha.
