I have a set of those that I'm working on. I'm sure you can only imagine my intentions for them.

That is an extremely sweet set up. I am totally jealous.

Ok now I get to be a n00b in the conversation. What is so great about Jason Hall triples?

DirtHog350,

There is nothing especially great about Jason Hall triples. They are simply big beautiful blocks of billet milled into a shape to adapt a three wheeler to an inverted fork. There are some three wheeler enthusiasts who are as rabidly into their mid-80s rides as we are into our technologically backwards bikes. The inverted fork is the Holy Grail to the modern three wheeler. Jason Hall provides the means for the dream to become reality:



He just also happens to make a set that fit the Yamaha Tri-Z. That's all...

More on inverted forks... please.

Mr. BigWheel,

Could you tell us more about those triple clamps? If the Tri-Z clamps fit both the 200 or 350 frames, then I'm assuming that those custom clamps will work with either as well.

(Just still thinking about that BW-XT 225/250+ idea.)

Ongoing progress to find why my BW200 is only giving 35psi compresion..

Well I pulled the head/cylinder this morning off the BW200, tip from a friend over the phone was to first spray carb cleaner into the intake and exhaust ports on the head and see if any comes dripping out from the valves.. well no drips out the exhaust side but a verrrrry slight weeping on the intake side. No drips, just a tiny bit of soaking thru and took a bit of time as well.

Next I removed the top piston ring from the piston, came over very easy.. with just one hand (that normal?) I placed just the top ring into the cylinder and got it lined up to measure the gap. Factory Service Manual states a standard end gap of 0.15-0.30mm with a limit of 0.6mm

Well I couldn't find my feeler gauges but had a pocket full of coins and was able to slide in US nickel which has according to the US mint a width of 1.95mm, even with the nickel there was still a bit of gap left on which I'd estimate the piston ring end gap to be near 2.3mm.. that seem very excessive?

Looking at the piston itself it looks in good condition, the cylinder wall has no gouges, the bottom 1/4 of the cylinder wall has the factory crosshatching, then the next portion is all very smooth, and finally the top tiny portion of the wall is not as smooth, guessing that is where the piston does not travel past TDC..

Next step I'm going to do is have the actual piston and cylinder wall measured at a shop to see if I just need to replace the rings or even need to bore it and replace with new piston/rings.

Thanks Mr. BigWheel for the education :)

Once I'm ready to do a full build on my bike I will add a set of those to my wishlist.

epix,
In my opinion it sounds like your top end is due for a slight over bore and over sized piston.

Check out this article.

Da Brooklyn BOMBER!

Well I took it for it's first LEGAL ride! Ok the trip to the shop was quazi legal plate on, signals on not wired and tail light w no brake light. Severasl hrs later took to the mean streets and even had a horn! Pumped up the tires to a whopping 12psi makes it more road friendly. Will post some pics tomorrow. Also some F*%KTARD trieed stealing it and my XR350 flat tracker. Found the lock cut this morning. Next investment is a camera to watch over the beasts and maybe a 12 gauge. LOL City living at it's finest.

ATR Rear

Greg24,

Earlier you posted you were going with the ATR 25x12-9 on the rear. What mounted diameter did you get for that tire? What's the swingarm clearance?

Thumb the mega bm

So the bigmower is back. Got a little sidetracked with the suburban and the 67 and the vista cruiser and the blaster and yz. But my custom hubs and rear end mounts are done finishing up the brakes soon. And then finally finishing the got dang wiring harness. Any ideas for it?
