I had both these aftermarket big bore 88cc top end kits on hand and thought it would be fun to compare them to each other. The CHP is geared towards an OEM look and the TBParts kit is not so much. Enjoy the video! These kits can be used on the vintage Honda Z50 Monkey CT70 Dax Mini trail SL70 XL70 ATC70 CL70 etc.

TB parts does offer a hotter camshaft for their 88 and 108cc V1 race head kits. it is the TBW0300 cam. it has .275″ intake valve lift and 230 degrees of duration @ .050″ .275″ exhaust valve lift and 230 degrees of duration @ .050″ I plan on trying one of these in my TB parts 108cc build. Great information you are sharing with us on your builds! Thank you!

I had to use a ct70 clutch so that it would kick start reliably, sir

[@andrefarden9220]

Good side by side comparison. Will you be building both and then compare?

[@VintageHondaMinis]

I'm only doing the CHP kit now. The bike will be long gone before I build a TBparts engine

[@johnoconnor5581]

If you go with a big bore kit will the OEM muffler handle the increased airflow?

[@VintageHondaMinis]

A stock exhaust will be fine at 88cc displacement.

[@danielgonzales8279]

That's expensive compared to just dropping a Lifan 125cc for power

Using original Honda engine vs a pitbike engine. Honda is going to cost more for sure
