RZ/RD 350 & Misc. 2-Stroke Tech BBS

They are original Allspeed's no real performance gains just much lighter than oem

What powervalve curve and ignition curve are you using? What pipe too?

Crank winding is when the ignition timing on the right cylinder is firing to early due to there being a delay induced by crank twist under load. Its not a crank out of true just a thing that can happen due to load and torque. This can happen even on a welded crank. The effect is it a temp differenti...

With the EGT it sounds like you have crank winding which can be compensated for in some programmable ignitions like the Ignitech

I need the side panels off a 31K asap, if anyone can help or has any please contact me.

Look at water ingress too as that eats the front edge of the pistons along sudden lean fueling. Did it go onto reserve? If not then look at water. I cant see any detonation on the pistons I see marks from a ring that has broken up as the upper groove has been eroded away, causing the ring to snag an...

They look like chinese fakes to me as the aerofoil in the centre isnt rounded off like the originals.

Over here I have seen a 392 hit 78RWHP with 28mm carbs and my pipes so 70is really easy with the Athena kits

I plan to weld the crankcases to make them thicker for trenching. Im looking to make a square engine 64 x 64 about 410cc ish. Should be very torquey and fun to ride as it keeps the std YPVS.

Hi all well I didnt expect this over my little Q but hey. I didnt even think about the date when I posted it lol. The crank webs come in many Diameters when they are stroked but I didnt know the +10 was on std sized webs. OK Q #2 what is the circle diameter of the widest part now assuming its the ou...

Hi all does anyone know the web diameter of the +10 crank please??

I was short a gas tank for a new project so I bought one of these from India: https://www.ebay.com/itm/324627242130?hash=item4b954a9c92:g:QkYAAOSw9j5goSVP The guy builds lots of alloy tanks for classics. I know there is a ton of complaints online about Indian gas tanks with questionable welds, rust...
