In the CR500 community we prefer to be called "hoon". ;)

They even have an annual CR500 hoonfest in the USA :kuda:

if that was running .06mm or .07mm squish it would last about 2 seconds.
I dont know what the squish is TBH, i was told it was machined for more bottom end powa, the guy does dozens of these and is well respected in the CR500 "hoon" community 8)

When I see him online I will ask what it is or I could wait until it is installed.

Update.

Now I will be at home more often i have made a start on the CRF alloy frame.

The challenge is to complete this by the 1st week in April ready for GC which is well before this Xmas as someone with a Jag suggested :P :lol:


Here is a few pics coz' we all like photos 8)

After many months reading about how many have done this I had narrowed it down to a 1/2 dozen different ways, however I decided to get this kit (which has only been recently available) which comes with well illustrated instructions, this takes so much work or rework of original components out of the equation, it is so simple. This bloke makes all the parts needed and ships worldwide and quickly by all accounts. Around the $350 shipped which is reasonable considering the Y piece is billet and the rootaround factor of the other methods and provides better support.

Really dont need to make anything it is simply a cut and replace job. There is a bit of fiddling about with modifying radiator outlets, relocating the CDI, mod airbox, different swingarm bearing spacer lengths and removing unwanted frame brackets etc. Anyway I will highlight each step as we get to it.

they say the hardest part is finding an experienced alloy TiG welder willing to do it although i have someone in mind. ;)

I am considering either revitalising the brushed/linished alloy look on the frame or full polishing, this can be done anytime down the track but I think the brushed looks more factory IMO.

Compression tests read 145+ over four kicks wide open throttle (140 is min spec I think). For now i will button on the new head until I get the bike built and the budget improves. Waiting on the new cometic head gasket to arrive.

New Hinson basket, oem fibres and steels ordered.

Using the steel plates for additional flywheel weight, OEM is best in this application, the Hinson basket has additional holes for better oil flow.

Quite boring really, it is a decompression valve for easy starting, like on a chainsaw it closes when it fires, saves the kickstarter casing and makes life a bit easier.

Ready for welding.

I can tell you attacking an alloy frame with a saw doesn't sit well with me but it has to be done, however the great thing about it is the confidence to take on similar projects in the future.

1st stage of welding is to have the main frame done so I can fit the motor, I really am trusting this jig to be accurate for engine clocking, chain alignment and save lots of mock-up time. 8)

Once fitted the 2nd stage is to prep the mounts for the coil, CDI and exhaust and a few other bits n pieces, then its finishing the fit-up, later on the suspension, plastics/decals and some big $$$ performance components will be done but I want it running for a shakedown ride first. :kuda:
