Where to buy +4 longrod

I would really consider getting it re-ported then....If that's not enough power something is definitely not right
 
It had like 150or 160 psi last time I checked It runs fine I'm just gonna run a different setup with a longrod

There will be VERY little difference in power between a +3 stroker crank and a +4 long rod engine.

If your setup isn't "powerful enough" then you need to re-investigate your engine setup. Something's missing from the equation.
 
Speedy is running a non ported Vito's 240 with a spacer plate and +3 crankshaft.

I think we found the problem, houston!

Stock vito's head is a better design than stock yamaha but NOT optimal. Stock vito's porting is relatively conservative (and casting flawed pretty bad).

Get a port job and the head rechambered, that thing will COME TO LIFE! You just won't believe how much better it will run. Mine lifts (read: not barely off the ground but the the point I can ride it) the front tires off the ground in the first 4 gears and then slides sideways in 5th and 6th! IT'S AWESOME setup right!

If that setup STILL doesn't have enough power, get Ken O'connor to set you up with a +4 long rod crank... he's got a track record with them already.


^^^^ not a particular track.... I mean, a history with them as in "track record"
