Predator 301 or 420 for drag mini

[frostyflammable]

I am going to be picking up a drag bike frame sometime in January and initially I wanted the 301 due to it being about 20lb lighter and I don’t want electric start or charging coil since I will be putting on a stage 2 kit on. My question is should I still go with the 420 and a 40 series or will the 301 be enough juice. Keep in mind this won’t be a pro drag bike and I won’t be going to races with it but just something fun to have.

I know there are other 420 like engines without electric start that I could go with as well, and I know this is a personal preference kind of question but would you go with a 420 (without electric start possibly but that can still take the stage 2 upgrade) or the 301? Both will get the 40 series.

Thanks.

Maybe something like this for a big block without electric start?

I think I saw Red Beard use this with the GoPower Sports stage 1 kit, I have to research if the stage 2 kit will fit this duromax.

But then again, I could wait for a $299.99 coupon for the 420, and then its pretty close to the DuroMax price without electric starts... choices choices.

The 420's weight disadvantage will reduced to hardly anything after installing a billet flywheel and ditching the e-start parts. There's only about an 8% difference in price between the kits and the 420 stands to make 25-30% more power without being all that radical.

My suggestion is the 420.

I had a mild 420cc on my mini dragbike and with no tuning went consistent mid 10’s in the 1/8 mile with a 2.00 60’ time on the bars. So I’m suggesting the 420 all the way also.

420 -301 = 119 Cubic Centimeters of Screaming Bald Eagles.
That's a 40% increase of 'Murica.

At that point, might as well use a Briggs 2100 or Briggs 305 for that lol.

Well, I cannot say no to screaming Bald Eagles! 420 it is!
