Honda Spree and Elite 50 Forums

My Spree is running better than ever now. It used to top out around 28 but now it is around 32 and sometimes it gets up to around 35. Once or twice it went past 35 and was screaming like a jet engine at which point I backed it down.

Just how fast is too fast for these little bikes?

mine tops out at 29mph. this sucks.

The limit with stock gearing is the engine rpm. I've had mine up to between 11,000 and 12,000 rpm. Stock the engine speed at 25 is about 8,000 rpm. If you are running at the higher rpm make sure and check your jetting. Go up step at a time with the main jet till it starts four stroking then back off one. If you can pull the higher revs it's time to look into a 1/2" belt, pulley mod, or bigger rear tire. That will push the rpm down and raise the speed.

"too fast?" never heard such a phrase..

More is better, too much is about right.

too lean? They really do scream before the piston is blown out the exhaust as a liquid.

When your face starts to melt...you're going too fast.

No such thing as too fast...

ive had mine going 50+ but that really has nothing to do with this thread due to my mods

dio speed DEMON!!!! The marker of all those youtube videos! Hahaha...how is that stroker going???

i learned how to put clutch springs on thanks to his video

screw that sob to a board and use an awl

speaking of this topic, is there a way to do a front disc conversion?

I hit 40mph on my 86 spree before the engine backfired, a huge stream of fire came out the back, and then my petcock broke.

need to find a new one or create a vacuum shut off.

40 mph is about 12,000 rpm. The Spree engine is speced for 8,000. They seem to handle 10,000 with a proper exhaust. It looks like they run lean or at least hot with a drilled stock pipe at high rpm. That flame was molten aluminum from the piston?
