1  For Sale / Want To Buy / Who Has It? / Re: Want to buy cam on: September 13, 2014, 08:55:34 AM
I am working with a company right now to have billet steel camshafts made for the vanguard. It will be a billet core and lightweight adjustable billet gear. They are expected to be done by late November/early December.

I would call Precision Cams and buy a new camshaft.  Finding a good used one may take a while, and installing a used cam can be a gamble considering you don't know the abuse it's been through. And i have some new starters here. Send me a pm.

You could save some money and just solder them up and drill them to the size you need.

Al Hodge at Performance V-twins has several nice parts for them.

As far as the camshaft gains, there are several other factors besides lift that make big HP and torque changes in an engine, including lobe center, lobe separation, and duration. Two cams with the same lift but different duration, lobe center, and lobe separation can have very different power bands and peak hp/torque. However, they could also be using the same legal camshaft but simply changing the cam timing.

The ideal timing for each engine can vary, depending on the compression ratio, rpm range you plan to run, and fuel you are using. High compression engines have a small window of timing.  Too much timing can cause pre-detonation and engine damage (ask the Briggs OHV single guys). On gas i usually run 31-34 degrees, depending on the blend of racing fuel and if it is oxygenated.  On methanol,  generally 35-38 degrees.

From what I read he has access to the rocker area so using an indicator to determine cam lift won't be an issue. The only problem I see is that the vanguard cheetah cam normally has around .308" to .310" lobe lift, and his cams have .304" lobe lift, which isn't much difference and might be hard to catch if he has a worn or cheap indicator that isn't very accurate. Especially if the cheetah cam has wear, or someone takes a few thousandths off the lobe lift to make it appear legal. 

Are these sealed spec engines, or are people allowed to build their own motors? If they are supposed to be sealed motors built to certain specs and cam timing, you could use the same method used to degree in racing camshafts. Use a degree wheel and check the cams for intake opening/closing to determine the intake lobe center and total duration. It would be a little more work, but it would be easy for me to spot a different camshaft this way.

Those motors are actually an easy find and getting parts shouldnt be an issue. They are horizontal shaft ohv single cylinders used on a lot of commercial equipment and generators. I would check around on eBay. I have seen several parts listed for those motors there.

Another way is to get some muriatic acid and wrap the crank journal with a rag and pour the acid on the rag and let it soak. It will slowly eat all the aluminum off the crank. But be sure to do it in a well ventilated area and away from other steel items as it will cause them to rust. Once most of the aluminum is gone you can clean it and then polish it as normal. Lastly mic it to make sure it is still within the required specs. 
13  For Sale / Mower Engines & Parts / New Kohler Command V-twin Racing Heads on: August 21, 2014, 02:00:24 PM
New set of Kohler Command v-twin built racing heads.  Started as NEW 30hp castings, heads have been ported, oversized stainless steel valves with big seats installed, bronze valve guides, dual valve springs with billet retainers and steel locators, machined for billet inserts for roller rockers, combustion chambers welded up and reshaped for higher compression and increased flow, and O-ringed. These were a customers who went with a different setup. All work was done by Lakota Racing, and he had over $900 total invested. I have the receipts and flow specs for the buyer. Again, these heads are brand new and have never been bolted on a motor. They would be a very nice set of heads for a BP or an FXT engine. $700 shipped obo

Yes, all the small block vanguard v-twins (23hp and below) have the same bolt pattern heads and will interchange. Bolt them on and go
