I would tend to agree with the above. I really enjoy my cub in the dunes, and I had had no trouble adjusting to the power delivery after a few rides in the dunes. There is nothing wrong with a good set of ported cylinders, but cubs do just fine in the dunes as well... csrmel, when I was debating which direction I wanted to go, all I had to do was ride a 421 cub in the dunes for a while and I was hooked...

Four to Score!

Word. :thumbsup: Double word. :thumbsup: And the inner hub is very cheap as well. Both are worth changing if either shows signs of wear. Sometimes 'next time' comes at a much greater cost... :ermm:

I agree with that statement, for I am in the exact same situation. I have always used haulers on my trikes... I agree, that is a lot of tire R&D. :thumbsup:

Had I known this at the time I bought mine, I would have sent mine in. It is now a serviceable shift cam just holding down a shelf. :ermm:

How does it run with TR6 pipes? I would like to hear from someone who actually has ported cylinders and TR6 pipes...

You do not need them.

I agree, it is a good deal. :thumbsup:

RPM has a lifetime warranty. The Lonestar Axcalibar on my R has a lifetime warranty, and I still have the receipt 13 years later...

The only experience I had with magnetic particle was checking landing gear struts, etc... Used fluorescent penetrant to check fan flades, etc, basically field testing just like you said. X-ray was used for engine mounts, etc... Used eddy current for ribs, spars, etc... It has been a while though. :cool:

I like straight paddles on all my bikes (banshee, ATC250Rs). I tried Skat-Trak Edge and I will never buy anything but a straight paddle again, even for my trikes. :thumbsup: Some say it takes more technique to use the straights, but I have never had any trouble doing whatever I have wanted to do with straight paddles...

Improper break-in could account for the less than desireable top-end results... :ermm:

I concur. :thumbsup:

NGK must have loved you.

I really think you will be much happier with Haulers with an eight inch wheel... :ermm: Eight inch 0.125 wheels will work well with which ever you purchase.

I have had much success with dye penetrant inspection (fluorescent penetrant to be exact). The biggest problem with dye or fluorescent penetrant methods is making sure the parts/components are adequately clean prior to the inspection process. You are correct, X-ray is definitely a better method, for it detects faults/defects under the surface. FireHead, I was going to try and throw you a curve ball by mentioning magnetic particle, but I figured it wasn't worth trying to get one over on you... :biggrin:

Only necessary if clearing the clutch arm with bigger carbs is an issue...

I would like to sell him the parts he needs for his next build.

The stator side of the shift cam is machined down, and a bearing is installed. The shift cam will have a bearing on each end just like it should have had from the factory. The modification is not going to be the fix all, solve all of transmission/shifting problems, but it does allow the shift cam to spin very easily... EDIT: The modified shift cam, modified shift star, and modified shift shaft will be a huge improvement in transmission performance (assuming things are not worn or damaged) over stock. You do not necessarily need the shift pro modification. I would inspect the shift adjust bolt and replace it if necessary while the basket is removed...

Do you have access to any kind of NDI test equipment (maybe eddy current)? A dye penetrant inspection would most likely reveal any surface cracks...

I use a shift cam with the bearing modification. Trinity sells the same thing for $129.99, and it has been fine for me. Alba's $149.99 is not such a crazy, low price after all!

Any chance there is a material deficiency involved with the cracked domes?

Are you referring to "off the shelf" domes or domes cut for special/specific applications?

Sounds like jetting to me as well, I would run the 35s with your setup... :thumbsup: Just to satisfy my curiosity, what needles are you using?
