    well he's still got his hand on the throttle. No impending crash that can't be saved by gassing it more. Maybe he did save it
    Don't you look at my accountant.

    yes dave... if you re-look at the photo, it appears that he is RE-mounting the bike.....

    he did save it.... we mush ave taught him well

    the photo before shows the front tire being pulled off the rim.
    no he didn't save it. He's only a B grade rider (hope he put his Taupo form in)

    Still got his hand on the throttle "I can save it". I like his optimism.

    Looking at using a RGV250 rod kit which is 5mm shorter than what I had. With the shiny transfers and the higher primary compression ratio, it should go like stink now.

    If you want to plan your ports using Jennings or Blairs methodology then this very good and inexpensive software is just the ticket.

    http://www.porting-programs.com/

    I have always known about Port/Time/Area but found it difficult and cumbersome to do, but with this software I am finding its easy (but still time consuming) to develop a porting plan for my new cylinder for Taupo.

    PortMap Porting Calculator

    Program features:

    * Calculates port heights from durations, or port durations from port heights
    * Assign fixed relationships between transfers and exhaust port. Enables all transfer
    port heights to be calculated automatically by just entering exhaust timing
    * Exhaust and main transfer timing can be entered by mouse click on graph, or typed in
    * Calculates required ranges of Jennings or Blair angle areas, mean areas and time areas
    * Adjustable graph rpm scale: 7k scrollable range, adjustable from 1k to 18k
    * Calculates possible ring flutter rpm
    * Mean piston speed
    * Suggests carburettor size
    * Power meter (you input expected bmep value). Switch between PSI & HP, or BAR & kW
    * Port design in separate cad window: enter shape values, or drag port cursors
    * Limitations on CAD: Single exhaust port, single boost port

    Port map analyzer

    Calculate your angle areas, mean areas, or time areas in minutes, directly from the portmap image:

    * Load png or jpg port map
    * Enter bore, stroke, conrod length and deck height
    * Mouse click once on each port to start port trace
    * Enter port height to top of barrel
    * Set horizontal and vertical cursors to calculate image pixels/mm
    * Enter port angles
    * View exhaust and transfer rpm ranges in angle area vs rpm graph
    * View time areas and power, with adjustable rpm and high-low tranfer bmep
    * Change bmep and power units between psi/bar, hp/kw
    * Measure portmap horizontal (mm, cord, %bore), and vertical (mm, crank degrees) distances

    One of the things I like about the software from porting-programs.com 2 Stroke porting software for the enthusiast http://www.porting-programs.com/ is that it makes it very easy to get the true total and mean port areas of the transfers.

    You input the port window as measured then the horizontal and vertical angles of the port and corner radiuses and the program draws the port and displays the true total and mean areas.

    When you select the rpm and bmep (power) you want it displays the port/time/area requirements as espoused by Jennings and Blair. Then gives you a running total of your ports as you modify them on the screen. It pays particular attention to the blowdown port/time/area requirements as described by Blair.

    Basically this software is the tool for doing what is in the Blair and Jennings books and you can toggle the software between them.

    All this for less than $30 US.

    Well its official, the simple setup is the best bang for bucks. Spent a very enjoyable afternoon with Buckets4Me dynoing his RS/GP125 team ESE bike, for a solid wide phat 18rwhp. He has always had the better bike at Mt Wellington and at Taupo it finished 2nd in one of the races.

    The mode’s are:- 1.5mm from the top of the barrel, 2mm “O” ring for a head gasket, std head, kX80 ignition fixed at 22deg, std exhaust port, std inlet and timing, std carb, 100 main jet and a RG250 pipe and bingo you have 18rwhp.

    We have spent 100’s of $$$$$$ and hours on the other bikes and can only show 2 more hp for our efforts. That 24mm carb class restriction sure does its job and holds them back.

    From what I have read, any attempts at high hp with a restriction in the system make for peaky hp, and that’s what I have, a peaky motor and all for another 2rwhp. SS90 is right, we should forget about our pre occupation with max hp and go for low wide phat power.

    When I have finished my present set of barrels I will seriously look at making a “Tractor” out of a 2-stroke, Speedpro looks to be doing ok with his engine. He has a very drivable ride that works well.

    pffft..... b-grade riders are hardcore!, id rather be at the front of b-grade than the back of a-grade, thats why b-grade riders arnt ashamed of being in b-grade its all about close racing and getting challenged by other riders.

    Thought I would contribute something, I have only read the first 25 pages so far. Heres a timing wheel.Print it off, glue it to card or plastic, mount on motor and start playing
