i'm happy to say that Ken O'Conner has hooked me up with a Vito's Fat Bastard pipe, and he has also agreed to port the cylinder and build the engine.

Ken, I talked to you earlier this year about building this engine, for reasons I won't get into online it never happened, but if you are willing, I'll pack everything up and get it shipped out to you. I have already purchased the Vito's crank and cylinder kit as well as hot rod bearing kit and...

Dualstroke; Do you have personal experience with a stock ported Vito's bigbore stroker motor?

Last year a friend of mine borrowed my blaster and melted it down in the dunes. I have since purchased vito's 240 kit with +3mm crank as well as new seals and bearings. My question is what pipe should I use with this new engine The bike currently has a FMF Fatty with Turbine core silencer...

This is similar to my experience on our three blasters. We run a 250 in a stock bike with autolube and a K&N, a 280 on a bike with 32:1 premix, FMF fatty and K&N with open lid, and a 290 on a ported bike with 32:1 premix , K&N with open lid.

I continue to be amazed about the obsession with leak down testing on this site.

I stand by my recommendation, look for the obvious stuff first. I have three blasters in my garage, one of them is a stocker with a K&N/outerwear. I run a 250 main in it and it is running rich when the cover is on. 2 jet sizes for cold air would require a 60 degree change in temp, and even...

Very unlikely that jetting is the problem on a stock bike, though I would put in a 250 main if you already have the carb off. Do some simple diagnostic testing before you crazy and pull the carb and do a leakdown. Check for spark, likely a fouled plug or loose wire, if you have spark check...

I recently installed a Vito's forged superstock piston in one of my three blasters. After reading a lot of negative comments about the superstock, I have come to believe that most of the negative posters have probably never seen one and certainly have not ridden a bike equipped with one. It is...

Why does the Mikuni Pocket tuner skip the 270 increment? The next interval after 260 is 280, yet the scale is not consistent with an interval of 20 (all other intervals are 10).

+1 Most of what I read on this forum about the Vito SS piston is misinformation. Vito's SS piston is forged not cast, they say on their site that they are made by wiseco. I assume they know who makes the piston they sell. It is hard to give the negative opinions any value when they...

I have an LT80, and have had problems like this if it is left sitting for a long time. Try rebuilding the carb, be sure to dunk it and get all of the ports / jets cleaned. The petcock also should be cleaned, and make sure the diaphragm is working. If the diaphragm is bad, fuel will not flow.
