Im very confused. Trail port cub motor with vf3's and 35mm pwk's. The two low-mid cubs Dave built, have been re-sleeved and had the exhaust ports dropped. We run carbon tech mid tension reeds and 28mm mikuni tm's bored out to 30mm on them. One runs pt mids, and the other runs pro circuits. What pipe are you running?

You need to figure out if its the base gasket leaking, the header pipe leaking, or the case halves leaking.

Use a carbide in the drill press to flatten down the bosses on the plate. Then use the dremel to arc the bolt holes.

Cheaper=yes, more reliable=no. Coolhead adds slightly more cooling capacity, easier to clean up and replace o-rings on a rebuild. Its also easier to just replace a dome if the motor comes apart on you. With a stock head you would have to have the domes rechambered or replace the head. You can also change out domes and fine tune your compression with a coolhead.

The micrometer was at zero when closed before taking the measurement then?

The stock pipes are focused up top, and have a narrow power window.

Do you have fatty pipes, or gnarly pipes?

I checked the current product line off their site yesterday and it was not on the list.

That comment was made in referrence to the vf3 cages. When I port a motor for a guy who runs vf3's, I have to grind the step out of the intake tract. If you dont, the vf3 cage opens directly into it. The vf3 shoots the air into the tract celing and floor, then its got to funnel down to go in. The chariot cage looks to me like it would work like a stock cage with a little more flow through it. I need to keep a straight shot in on the tract with good velocity. I dont need a ton of petal area like a vf3 has.

OK.

I dont need it, I have a low-mid setup. I need the tension of a low-mid carbon petal with the knifing of a stock style straight flowing cage. My carbon tech mid petals work great on stock cages with knifing. It would just be cool to get a little straighter flow through them. It looks like your cages would push the air straight through instead of splaying it out towards the top and bottom of the intake tract.

He has a twin carb needle in it. Needs eek or eej. Main at 195, 45 pilot 1.5 turns out. Start out with clip in center position. Problem fixed. :biggrin:

You should be running a mainjet in the range of 350-390 with those carbs. I have all the specs for it in my notebook, but your way off on mainjet size. Its bogging because its lean.

What is an oc?

Question, will stock reeds or say carbon tech reeds bolt up to these chariot cages? I wonder if I can get them to make a set with the center rib in it still?

Why did you buy one if you didn't know where it was gonna hide it?

I checked their website and only saw a pipe for the yfz450.

It wasn't programmed for a big bore. Big bore timing is the same as small bore except for advance in most cases. The only change I could see in making a big bore curve is to accentuate a certain area of the powerband. You could do that on a small bore anyway. DAJ uses curve 3 on his drag bike as well. Its just a well built factory dyna curve. My motor is a stock cylinder, stock stroke, stock bore, ported 350 with Pro circuit pipes, and 185psi compression. I just took curve 3 and added 4 degrees to each section of the timing table to advance it.

All the pics I used in the dyno thread were from the photo bucket site.

Do you still have stock headlight connectors and wiring?

Be close to the stock carbs you ran with maybe a few larger main jet size at the most.

I programed the +4 into the curve with the programmer kit. I run straight race gas.

which 28mm carbs? Flat slides, rounds?

I put one in my best friends bike. It works, we dont have problems with it.

I second that statement.
