Re: Punsun V twin questions

You must do a static timing check. If you look the top of the output fittings on the fuel pump are slotted. This will allow you to change the fuel timing about 3 to 3.5 degrees. The Pusun's and all the other Chinese diesels that I have screwed with have timing marks on the flywheel. They use BTC for...

New Video

I posted a new video on Youtube. Its an 18 minute ride on my V twin turbo diesel. I decided not to edit it down as it really shows the bike riding in the real world. The top speed was 65 mph. I won't say what the posted limit was 8) http://www.youtube.com/watch?v=DgsxiKslwRU

Re: In production Flying Car-Make this a Trike.......... diesel?

Yup some poor sucker made the news a while back out in British Columbia with one of these. landed in the trees after a control failure. It will never be road legal, can't be flown in much over 5 mph winds and slower than a donkey. Other than that great idea :shock:

Re: Disappointing turbo performance

Just going to throw a crazy idea out there. Has anyone measured the crankcase pressure? I know the v twins have an outrageous amount of blow by when turboed. There is no way the little stock piss hole vent can handle all of the back pressure. This could be part of the problem that the singles are ha...

Re: More compact mounting of CVT

You can't flip one without the other. As the primary closes the belt centre moves to the fixed side of the primary. At the same time the secondary opens and the belt moves away from the fixed side allowing the belt to remain centred. ... Have sat their and done this mentally for hours now.... and I ...

Re: More compact mounting of CVT

You can't turn the secondary around it won't work unless they make a reverse helix. Most units have the spring and helix on the inside but not all. Flipping the primary should be doable. The problem I see with moving the primary is supporting the shaft as it cannot pass through the clutch. So the tr...

Re: More compact mounting of CVT

If you use a Quad CVT you may not be able to get springs, weights and helix that will work in the RPM range of your diesel. Most quad CVTs are designed for much higher HP and RPM. Spinning it faster to get it to engage will work but then the fun starts as you still have lower HP and the torque will ...

Re: 67 Triumph Bobber

Maybe I can shed some light on the clutch setup. Out of tyhe box all Comet 40's come with what they call the standard 4 cycle setup. The engagement is at 1600rpm and the driven has a red spring. This is setup for things like golf carts etc. And as it happens it is almost bang on for a 10hp diesel bi...

Re: Diesel Single Bobber Build

Looks good so far. Its amazing how much these little turbos whip up the oil. If you can use a piece of copper tube or something like it on your turbo return it will help dump some heat out of the return oil

Not clubby just speaking turbo. Maybe the 30+ years of turbos and gas turbines makes me forget to explain things 8) IAT= intake air temp also called TIT turbine inlet temp 165 ddegrees F would be the temaerature. And at 10 psi 165F is very good "...mine was making IAT around 165f..." Huh???? Thanks!...
