DYNO RUN Stock Z50

[smcdonn]

Alright I decided to do some dyno pulls of my buddies stock Z50 (with rev box) as we will be installing a big bore pretty soon. I have seen some requests for dyno runs so here is our baseline. Peak number was: 2.17hp @ 7834 rpms. In the coming weeks I will get the big bore installed (TB 88cc) and repost numbers. By the way, hows the stock carb and jetting with the 88cc big bore?

...with 4 of these to keep all that raw horsepower in place

Stock carb is WAY too small for 88cc Its actually too small for 50cc! 'nutcase

Alright well the numbers are in. 2.89 hp with the TB 88cc big bore. No jetting changes were made as it seems to be running pretty good. Oh and heres a pic for a good laugh.

Bahahahahahahahahaha!!! I love it!!!

You'll notice a fairly good gain up top if you go with a 20mm carb.

[qwoke-q]

Damn, I thought it would be more. Throw the race head, carb, and exhaust on there if you get a chance.

Grief, for a second I thought the back strap was hooked to the sprocket. Isn't that a 24% gain?

[BlingBling5O]

You guys have the dynojet on a trailer?

[smcdonn]

No I built the dyno myself, just had a dynojet sticker laying around from a jet kit.

[smcdonn]

Heres the HP graph comparing the two setups. Amazing how bad the stock carb chokes this thing down.
