I don't think it's possible to bore these small engines out 0.08"!! The max OEM recommendation for a Briggs flattie is 0.03", and all these small engines have thin wall blocks.

I don't think you'd need to worry about overheating, because I think you'll have a hole in your cylinder before that happens.

Why 0.08"?? Is there a particular piston you want to use? Dynocams has lots of Wiseco and a few Burris pistons for sale.

It may be a differently designed block for the 225, though.

I bet Flyinhillbilly can answer this, I'll let someone else chime in.

The 225 block is already 72mm bore, the casting all looks really nice, and I really love all of the extra bracing.

You can see in the pictures that there really is t much flashing, or casting flaws. These blocks have a lot of extra bracing built in, and they are very much worth the $100 that they値l set you back in my opinion.
This one is slated to be a 14.5 cubic inch open motor. I知 going to do a couple of videos of the build as soon as the rest of the parts come in.

Maybe the pull starter and ignition coil , not much else

How much of the stock predator parts do you want to install in the nice block would be the question.

You can buy just the long block , link was in the first post.

https://www.gopowersports.com/225rs-...ne-long-block/

I think you missed the point , just buy the whole 225 engine or work with what you have. Impressive power output is achievable with the predator's stock bore and stroke. Reaching the point of diminishing returns on a $100 china clone is not much fun.

I知 excited to get going on building mine too. I知 still waiting on the head. It should be a pretty mean little motor. I知 going with a tunnel ported warhead with 34/28 valves, billet 1.3 rockers, 2.3 super alloy stroker crank, custom ground 360 lift cam, all fed by a Clements 34mm flat slide carb. This one should be a high rpm screamer.

Mine is going to be 238cc, so for 10cc I should’ve just bought one of those. I guarantee it would’ve been way cheaper.
Tillotson has really stepped up over the last year.
