Saxat ifrån HBF om motorn. Behöver absolut inte vara sanningen men det kanske kan vara en vägledning ändå.

Full mod will eat it alive any time any where, and with flywheel and all, full mod still revs higher.

Mera info ifrån Bruce/Gizmo:

Guys i have been very busy and had no time to test this new Cr300B. We used 2 baja's both have the same everything. one has a stock zenoah 290 and both had 17/57 gears , Rear Dom pipe. now we have found that the Cr300B had good mid range and good top end. But in drag race with stock zen 290 we see that the CR290 is a little faster but not much.As i always say there is not 7Hp engines IMO. I have removed the Hp #'s on my website.But i will say that the CR300B bottom end is by far the nicest set up i have seen.You would be very happy with it.But if you want a bullet proof engine this is great one to have. The cyls have a lot of mods you can do to them also. Sorry for not posting sooner.

Så lite vassare än en zen 290 men långt ifrån 7hk tydligen!

Eftersom V1 av denna motor kanske inte var så testad innan den släpptes och flertalet fick problem med den så är V2 ute nu.

Ser ut som det både kan komma in och ut lite mera luft nu!

Som det ser ut så lär det bli fler varianter innan kylningen fungerar..
Man har sett det så många gånger i jobbet osv, ett konstruktionsfel som ska åtgärdas, men man väljer inte den rätta lösningen på problemet (omkonstruktion) för det blir för dyrt med nya verktyg osv, utan man lägger ett billigt 'plåster' som man hoppas ska fungera, men ingen egentligen tror på. Ungefär så såg detta ut. Fläkten blåser lite på cylinderfoten typ.. Kylningen behövs mest vid toppen och utblåset.
